Doctor Who

Season 7

Asylum of the Daleks

1. The BBC had to put out a call asking anyone who owned a Dalek to contact them because they did not have enough to make this episode and that they needed Daleks of different eras.
2. The presence of Jenna Coleman in this episode was successfully kept secret, despite the episode having several preview showings prior to broadcast. After broadcast, Coleman and Steven Moffat both issued statements thanking fans and the media for keeping Coleman's debut - months before her official first episode, the 2012 Christmas special - a secret.
3. This has the second showing (if you look carefully) of the special weapons Dalek in the background which was only ever seen in Remembrance of the Daleks - 4 of 4 which has a single 'cannon' weapon and no domed head.
4. Karen Gillan admitted that she had not been scared of the Daleks before working on the episode.
5. The snow scenes on the asylum planet were filmed in Spain during the production of "A Town Called Mercy"
6. Russell T. Davies loaned the production a TV Dalek he owns for use in this story.
7. The scenes with Oswin were filmed in two days.
8. Steven Moffat wanted this episode to make the Daleks scary again.
9. Rory was originally meant to have a beard in this episode, which Amy would hate and he would shave off at the story's conclusion. Between seasons, Arthur Darvill was appearing on stage as Mephistopheles in Doctor Faustus, and Steven Moffat planned to have him keep the beard grown for that role. However, this plan had to be abandoned when it was decided to make this as part of the second recording block alongside "The Angels Take Manhattan".
10. 25 different Dalek props were used in this episode.
11. The logo in the title sequence featured the texture of a Dalek, in keeping with the varied "blockbuster" themes for each of the opening titles of the first half of the series.
12. Oswin was originally conceived as being a fan of Elvis Presley, whose music would play throughout the episode and inspire the Doctor to give her the nickname "Blue Suede Shoes". However, when obtaining the rights to use these songs proved problematic, it was decided that the soundtrack to Bizet's Carmen would feature instead.
13. When Oswin accesses the dalek database for information on the Doctor, the three words visible on her screen are "Predator", "Doctor", and "Hatred". The daleks had told the Doctor that he possesses, "...such divine hatred."
14. This story marks the first appearance of a new title sequence.
15. Jenna Coleman's scenes were filmed over six days on a closed set with a green screen which she acted to.
16. The continuity-patching placement of the Dalek Parliament on "Skaro 2" was cut from the script.
17. This episode was shown at the Edinburgh International Television Festival in August, just as was done with "Let's Kill Hitler" in 2011.
18. Ruthie Henshall was originally cast as Darla.
19. In the very first scenes of Amy Pond's photo shoot, her hair is done up all curly and remarkably resembles River Song's.
20. When The Doctor asks why these Daleks are special, Oswin says they are survivors of wars. One of them being Vulcan. the location of the human colony in Power of the Daleks, also used as the name for Spock's home planet in Star Trek, both in 1966.
21. When the Doctor tells Amy and Rory,on a scale of one through ten, 11. This is the 11th Doctor.
22. Oswin is played by Jenna Coleman. Coleman was originally cast as the Doctor's new companion and scheduled to make her first appearance during the Christmas special. Steven Moffat came up with the idea to cast Colemen in this episode in order to generate speculation about her character. The Christmas special later revealed that the new companion's name is "Clara Oswin Oswald" and that she is somehow connected to Oswin.
23. Steven Moffat realised that the Doctor would never actually see Oswin in her human form. This meant that the actress portraying Oswin and the actress cast as the new companion could be one and the same. As such, Moffat did away with a suggestion that Oswin might be a Dalek whose insanity has caused it to believe itself to be human.
24. Although stressing that the first syllable of "Exterminate!" sounds like eggs was new to television, it was not the first time the notion appeared in licensed Doctor Who. It was done about 20 years earlier by Paul Cornell in Metamorphosis. The usage is remarkably the same in that Doctor Who Yearbook comic, except that it's the Seventh Doctor who is turning into a Dalek and saying "eggs".

Dinosaurs on a Spaceship

1. David Bradley (Solomon) would later play 'William Hartnell' in An Adventure in Space and Time (2013).
2. The scene where Amy, Riddell, and Nefertiti stumble upon a sleeping Tyrannosaurus rex was almost cut as it was originally intended to feature CGI raptors, which were too expensive. However, Millennium FX realised they could use a baby T-Rex that had been in an exhibit they designed.
3. Saul Metzstein (director) later said that Matt and Arthur's kiss was not scripted.
4. Matt Smith had to wear padded trousers when riding the triceratops, and recalled it was "a painful couple of hours, a laugh though and definitely worth it".
5. The CGI models of the raptors are the same as those used in Primeval (2007).
6. Half of the triceratops was actually built and pushed by crewmen when Matt Smith, Arthur Darvill, and Mark Williams were riding it. The rest of it was filled in with CGI by The Mill.
7. The production team had to be mindful of the series' budget when planning the effects and sets. Chris Chibnall commented that "it would be very easy to spend £300m on this but we don't have it". As such, the dinosaurs could not dominate the episode, and Chibnall had to tell "a big other story".
8. The episode contains one of the biggest sets ever built for the show.
9. Solomon, was modelled on a "well-known nightclub owner with long hair". Chris Chibnall described him as "half businessman, half Somali pirate".
10. For this episode, the title logo's texture resembled scales, like those of a dinosaur. It was also given a green hue.
11. Chris Chibnall also wanted to incorporate frontiersman Charles "Buffalo" Jones (1844-1919), who helped save the American bison from extinction. However, Steven Moffat was concerned that this character was too similar to the cowboys of A Town Called Mercy, the story which would follow Dinosaurs On A Spaceship in the season schedule.
12. The robots were previously designed by Millennium FX for Mission 2110 (2010).
13. Chris Chibnall intended Riddell to have once saved the life of the Doctor, who was now doing him a favour because Riddell was fated to die the day after he was collected from the African plains. (Both of these references were eventually deleted during editing.)
14. This episode takes place in 1334 BC, 2367, 1902 and the 2010s.
15. John Riddell was inspired by Alan Quatermain, the hero of a series of novels by H Rider Haggard.
16. The part of John Riddell was written for a man in his 30s but played by Rupert Graves who was 48 at the time of filming.
17. The role of Solomon was written for a man in his 50s but played by David Bradley who was around 69 at time of filming.
18. David Bradley (Solomon) and Mark Williams (Brian Williams) both play in the Harry Potter series as Filch and Arthur Weasley, respectively.
19. The voices for the two robot comic relief are provided by Mitchell and Webb, a British comedy double act, composed of David Mitchell and Robert Webb. They are best known for starring in the Channel 4 sitcom Peep Show.
20. The cast for this episode include actors from three highly popular TV/Movie series: Rupert Graves (Riddell) plays DI Lestrade in Sherlock (2010), Mark Williams (Rory's father, Brian) plays Arthur Weasly in the Harry Potter series, and David Bradley (Solomon) plays Walder Frey in Game of Thrones (2011). Bradley also plays Argus Filch in Harry Potter.
21. The role of Nefertiti was offered to Angel Coulby.
22. When the Doctor shocks the two robots, they start singing "Daisy Daisy" this is what Hal, the ships computer in 2001: A Space Odyssey (1968), sings when he/it is shut down.
23. The idea of Nefertiti running away with John Riddell, is actually quite plausible due to the complete historical gap in the later years of her life.
24. Originally, Nefertiti knocked out the Doctor and gave her own life to destroy Solomon's ship. When this was felt to be too similar to other self-sacrificial moments in the final cycle of Amy-Rory episodes, Steven Moffat instead suggested that the Doctor and Nefertiti could be saved by having the TARDIS materialise around them as the missiles strike Solomon's pod. Subsequently, however, Moffat decided that this lacked drama.

A Town Called Mercy

1. Much of the episode was filmed around the desert area of Almería, Spain, where studios have built Wild West-style streets that have been used in the making of over 100 Western-set films, such as The Dollars Trilogy.
2. While Matt Smith was allowed to try riding the horse, most of the action shown in the episode was done by his stuntman.
3. Filming the episode in Spain was cheaper than constructing a set in the UK.
4. Ben Browder accepted his role because his children were fans of the series and he also wanted to do a western.
5. The Doctor's confrontation with the townspeople outside the jail was inspired by To Kill a Mockingbird (1962).
6. The major change made to the episode was the elimination of a hauntingly beautiful melody emanated by Kahler-Tek, which typically presaged his arrival. Originally, Kahler-Jex eventually revealed that this was music he played during the torturous operation which created a cyborg, in order to drown out the subject's screams.
7. Toby Whithouse stated the hardest scene to write was where the Doctor is forced to use a gun, because the Doctor is a pacifist and he would need "the right sort of emotional journey".
8. It took about three and a half hours for Andrew Brooke to have all his make-up applied. Due to the costume, Brooke had to act with just his left eye.
9. An early version saw the cyborg killed off partway through the story, which then focussed on the true villain of the piece, Kahler-Jex. This approach was soon inverted, with Kahler-Jex shot to death by Isaac's mad father George, and the drama of the final act generated by the cyborg seeking to punish the town that had deprived him of his revenge. This culminated in the Doctor confronting Kahler-Tec with the projected image of a woman named Kahler-San, who wore the same pendant as the cyborg. Although Kahler-Tec saw through the deception, it was enough to convince him to halt his assault on the people of Mercy.
10. For this episode, the title logo's texture had a wooden look with gunshots, representing the story's Western setting.
11. Originally, Rory was the one in favour turning Issac over to the gunslinger.
12. Scott Bakula was first offered the role of Isaac but dates clashed with other projects.
13. Working titles for this story included The Gunslinger and Mercy.
14. This was the first episode of the BBC Wales revival whose visual effects were not credited to The Mill.
15. This episode takes place in 1870.
16. Not the first Doctor Who (2005) to be shot in Spain; the first were Doctor Who: The Two Doctors: Part One (1985) and Doctor Who: The Two Doctors: Part Two (1985).
17. Steven Moffat was keen on putting Matt Smith in a Western setting, who he called one of the last people one would expect to replace Clint Eastwood.
18. The Wild West has not been a setting for a Doctor Who episode since the "The Gunfighters" in 1966. Toby Whithouse was advised not to watch The Gunfighters by the other writers, who said it was "not exactly the jewel in the crown"
19. Issac was initially a robot, but quickly became a cyborg (called Kahler-Tec, then modified slightly to Kahler-Tek) because Toby Whithouse felt this offered greater emotional depth.
20. This is the first episode not to feature the TARDIS interior since "The Doctor, the Widow and the Wardrobe".
21. Karen Gillan later starred in the western In a Valley of Violence (2016).

The Power of Three

1. The emphasis of the story was heavily altered in post with a huge chunk of the Shakri scenes being removed .
2. Kate Stewart mentions having "ravens of death" in the Tower. There are six captive ravens that are cared for and live in the real Tower of London. Legend has it that these ravens are the guardians of the Crown and the Tower, and if the ravens ever go away the kingdom will fall.
3. Steven Berkoff proved difficult to work with. He repeatedly went against the wishes of Douglas Mackinnon, in some cases just plain refusing to do what he was told, deliberately ruined takes (sometimes by reading his lines as badly as possible), and had several temper tantrums. Virtually all the footage they shot featuring Berkoff was unusable, and the ending as broadcast is all they could cobble together from the few scraps they were able to salvage, plus some pick-ups filmed later on with just Karen Gillan and Arthur Darvill (as well as some shots of Berkoff which were allegedly taken from when the camera was left running between takes, because even the filmed footage of Berkoff walking across the floor could not be used) - it was not originally the intention for Shakri to be a hologram, or for the plot to effectively be resolved entirely by the sonic screwdriver, but that was all they were able to do with what they had.
4. Matt Smith put disgust into the Doctor's remark concerning Twitter in the episode, reflecting his real-life decision to stay off the social network.
5. The episode was largely restructured to introduce the invasion storyline earlier. The episode originally began with scenes such as the adventure with Henry VIII and Amy at the engagement party.
6. The character of Kate Stewart had previously appeared in Downtime (1995).
7. Producer Marcus Wilson stated that a "hundred" individual cube props were made, with "many more" added with CGI.
8. In one throwaway gag, the Doctor is seen randomly holding a cabbage. Tom Baker once famously joked that he wanted a sentient cabbage as the next companion.
9. The working title for this episode was Cubed.
10. Despite playing the main villain of the story Steven Berkoff only has 8 lines.
11. The final TV role of Peter Cartwright who died soon after working on this.
12. Amy and the Doctor's conversation outside the Tower of London could not be filmed at the genuine location due to the London Olympics, so it was shot on studio in Cardiff and the live action was combined with other footage to create the illusion.
13. One major element removed from the script was the appearance of Prime Minister Stephen Carter. Suspicious of the Doctor, Carter would bar him from the United Kingdom, resulting in the Time Lord's absence from a long stretch of the narrative.
14. Steven Berkoff was required for three days of filming.
15. Chris Chibnall drew upon his childhood love of the Jon Pertwee era in writing an alien invasion story featuring UNIT.
16. This episode takes place in the 2010s and on June 26, 1890.
17. Chris Chibnall's brief from showrunner Steven Moffat was to "live with the Doctor - The Man Who Came to Dinner, Doctor Who (2005) style."
18. For this episode, the title logo's texture resembled the Shakri cubes featured prominently in the episode. Also, the shade of red in the time vortex appears to be more crimson, rather than orange, with the lightning strikes causing an additional effect of electrical surges spreading out from the tips of the bolts. The vortex also turns purple with the sharpness seriously decreasing when the Title appears.
19. Chris Chibnall described this episode as "a lovely big Earth invasion story" but different from the ones done before, as it focused on Amy and Rory's time with the Doctor and the impact of him on their lives.
20. Alan Sugar's cameo was in fact filmed on the set of The Apprentice (2004), with director Douglas Mackinnon standing in for the person who was fired.
21. A scene with bomb disposal experts Conroy (Okezie Morro) and Sullivan (Henry Luxemburg) was deleted in post.
22. There was an extended action sequence in the climax in which Rory took down the two orderlies. The Shakri was not a hologram, and instead was defeated when Amy and Rory attacked him with the syringes retrieved from the orderlies, and the Doctor used his sonic screwdriver on the Shakri's devastating ocular weaponry. However, it was felt that this part of the episode detracted from the focus on Amy and Rory's life together.
23. Chris Chibnall was also inspired by the story of the MSC Napoli, a 2007 shipwreck along the Devon coast near his home, when people showed up in droves to claim merchandise which had washed up on the shore.
24. The abductee who led Rory to the Shakri ship was not Brian Williams, but instead a patient named Anne.
25. Before being taken by android orderlies himself, Arnold Underwood was to make reference to a neighbour named Elizabeth Cracknell who had not returned home from the hospital.
26. The read-through of the episode was held on April 27, 2012.
27. This was the last episode filmed with Karen Gillan and Arthur Darvill. The last scene shot was of their characters entering the TARDIS with the Doctor. When the doors closed behind them, all three actors hugged each other and began to cry.
28. The episode originally ended with Amy and Rory deciding to take "one more" trip in the TARDIS despite Brian's unease. Steven Moffat suggested that this be changed to have Brian encourage them to go with the Doctor, providing a less sombre and more subtle lead-in to Amy and Rory's final story, The Angels Take Manhattan.
29. Kate Stewart claims that she's got "officers trained in beheading [which could be in reference to the Headless Monks, and] also Ravens of Death". In the season 9 episode, Doctor Who: Face the Raven (2015), Clara Oswald (The Doctor's companion following the loss of Amy and Rory) is Killed by a Raven. This could be a subtle hint implying Steven Moffat had Clara's timeline planned out more than 3 years in advance.

The Angels Take Manhattan

1. Filming in New York was attended by thousands of American fans, which surprised the cast and crew.
2. Karen Gillan insisted on reading Amy's afterword to Matt Smith when his reaction was filmed. They were not expecting it to be in front of a crowd in Central Park, and Smith said he had to "treat this like a play". Because the content was so secret, Gillan had to read very quietly and Smith could not hold the real page because a spectator might take a picture of it. Gillan found that she only had one page of the script, and had to improvise the rest.
3. Matt Smith and Karen Gillan got very emotional filming the final graveyard scene.
4. This episode features the last usage of the TARDIS console room that debuted in "The Eleventh Hour".
5. The newspaper Amy reads in the park has the headline "Detroit Lions Win Superbowl". As of 2022 the Detroit Lions have never even appeared in the Super Bowl, let alone won it (they are in fact the only NFL team that has been active for every Super Bowl season but never appeared in one). This could be either an inside joke or a hint that this is an alternate time-line.
6. The mother and son statues that turn into angels are identical to the Pioneer Woman statue located in Ponca City, OK.
7. This story originally featured the Daleks. It was decided that the Weeping Angels were a better fit.
8. The song playing when we first see the Doctor and Amy and Rory in the park is "Englishman in New York" by Sting.
9. This episode has individually stylized opening credits: the time vortex appears blue and grey, and the title logo resembles the Statue of Liberty in colour and pattern.
10. The crew did not take any props of Angels or the TARDIS to New York. They were instead added in post-production.
11. A possible alternate ending of The Angels Take Manhattan (#7.5) would had seen The Doctor and River visiting a retirement home in present day Manhattan. Where they find an dying 87 year-old Amy in bed. Amy gives The Doctor a letter and says "Raggedy man. Goodbye!" and dies, leaving The Doctor heartbroken. The Doctor and River return to the TARDIS and River leaves The Doctor alone to read Amy's letter.
12. Just before the Doctor exits the Tardis to see River Song, the plaque that he is using as a mirror reads"TYPE FD 12MK V11 Rolls-Royce Motors Crewe England"
13. This episode takes place on April 3, 1938 and in 2012.
14. Amy and Rory's scene on the rooftop was filmed in a car park in Cardiff, Wales, with a greenscreen standing in for the New York skyline.
15. Originally, the item made in ancient China at the Doctor's request was a TARDIS-shaped puzzle box. River discovered it amongst Grayle's collection and stored her vortex manipulator inside. The Doctor then used the vortex manipulator to travel to 1938 New York after locating the puzzle box in a museum in the twenty-first century.
16. Originally, when the TARDIS was unable to materialise in New York, it was shunted back in time to the Viking era.
17. The Chinese foreman reappeared later in the script: Grayle was transported back to his workshop by the Weeping Angels, and was put to work making the very things he had collected as antiques. The final script instead saw Grayle wind up as a slave during the Renaissance, as depicted in one of his paintings; however, this was lost during editing.
18. Early drafts saw more obvious time manipulation at Winter Quay, with multiple versions of both Rory and Sam Garner present at different ages.
19. Zac Fox is credited as playing the Photoshoot PA but there is no trace of him in the story at all.
20. A possible extended ending to The Angels Take Manhattan (#7.5), which tied-in with the 2012 Christmas Special The Snowmen would had seen The Doctor return to the TARDIS after reading Amy's letter. The Doctor decides not to allow River Song to travel with him with the TARDIS and has become disillusioned with traveling through time and space, fighting evil and has had enough of gaining and losing friends and ruining their lives and drops River off. The TARDIS arrives in London, 1842 and The Doctor sets up the staircase in the sky and shuts himself away in the TARDIS and becomes a recluse. Vastra, Jenny and Strax, suspecting something terrible has happened to The Doctor and that The Doctor needs time, agree to keep people away from him and not go up the staircase and bother the now reclusive Time Lord.
21. The episode's title references the 1984 film "The Muppets Take Manhattan," which was in turn inspired by the 1925 song "Manhattan" by Lorenz Hart and Richard Rodgers, with its lyric "I'll take Manhattan, the Bronx, and Staten Island too."
22. When the scene where The Doctor reads Amy's letter was filmed, Karen Gillan who was off-camera, sat next to Matt Smith and read to him Amy's letter. When the director called "Cut!" Smith broke down into tears and started to cry.
23. In "God Complex" (S06E11), the Doctor leaves Amy and Rory behind in their new house to protect them, remarking, "What's the alternative? Standing over your grave?", which is unfortunately exactly what happens at the end of "The Angels take Manhattan".
24. On Amy and Rory's gravestone, it is marked that Rory's middle name is Arthur and he died at the age 82 and Amy died at the age of 87. Arthur Darvill was born on June 17 1982 and Karen Gillan was born on November 28 1987.
25. Amy's exit was a mutual decision between Steven Moffat and Karen Gillan. Gillan stated that she wanted to go "on a high when the character was at her prime" and to "go with everything that she wants". She wanted her character to have a final ending, and ruled out returning to the show in the future as she felt it would take away from the impact of her final scene.
26. An unfilmed postscript written by Chris Chibnall, entitled simply "P.S.," showing how Brian, Rory's dad, learned what happened to Amy and Rory was released on the BBC's website and on YouTube as a short video using storyboards with text from the script and a voice-over by Arthur Darvill (Rory). The video shows Brian in Amy and Rory's house watering the plants, as he'd promised to do, when a knock at the door interrupts him. The man at the door gives Brian a letter written by Rory which tells Brian briefly how he and Amy met their fates. It also tells Brian that the man who delivered the letter is their adopted son - Brian's grandson.
27. Karen Gillan refused to read the script for a few weeks after she received it because she "didn't want to make it real". She said in an interview, "I literally couldn't read it without crying. It was the most highly-charged read-through I've ever experienced. But I couldn't have asked for a better exit. I don't think it'll be what people expect."
28. Amy asks the Doctor to return to meet a young Amelia Pond the morning after he left her waiting in the garden in "The Eleventh Hour" to tell her about the adventures they will have together. The older Amy was dreaming about that morning when the Doctor came back to pick her up the night before her wedding at the end of The Eleventh Hour. Steven Moffat said of the scene, "After showing Amelia Pond in the garden as a young girl in The Eleventh Hour, Karen's first episode, the final shot in Saturday's The Angels Take Manhattan is a punchline I have been waiting to tell for two and a half years."
29. When the ending of The Angels Take Manhattan (#7.5) was filmed. Karen Gillan whom was off-camera sat next to Matt Smith and read to him Amy Pond's farewell letter. When the director called 'Cut!', Matt Smith broke down into tears and started crying.
30. Chris Chibnall wrote a scene where Brian Williams becomes aware of Rory and Amy's fate. The scene was written to be a DVD extra, and was not filmed due to time constraints.
31. Final appearance of Rory.
32. The music in the background as Amy and Rory are falling from the Winter Quay to create a paradox is either the exact same or reminiscent of Series 3's Blink (Suite) score from the episode Blink.
33. Some fans were disappointed with certain plot holes in this story; for instance why, even though The Doctor can't go back in time and retrieve Amy and Rory, he couldn't land a hundred miles away then either catch a train or phone them.
34. During rewrites Steven Moffat went back and forth deciding whether or not Amy and Rory should live or die. He eventually decided that death would complement the storyline involving the "old, sentimental" and "dangerous" characterisation of the Doctor.
35. The Doctor gets upset that he has to break River's hand because he read about it in a book about the future. Any number of things could have happened differently. River just needs to make sure she writes it properly.
36. Amy revealed as the author of the Melody Malone detective novel foreshadowed Karen Gillan starring in Not Another Happy Ending (2013) as successful first time Scottish novelist Jane Lockhart.

The Snowmen

1. The Snowmen features a first-ever special effect for the series: a single camera shot following a character (Clara) from the outside of the TARDIS, through the doors, and into the console room.
2. The Doctor first met the Great Intelligence in his second incarnation in the story Doctor Who: The Abominable Snowmen: Episode 1 (1967). He battled against them again in the London underground in Doctor Who: The Web of Fear: Episode 1 (1968). A map of the London underground appears on the top of the lunch box the Doctor gives Dr. Simeon.
3. When The Doctor is introduced as Sherlock Holmes, the music mimics the style of the music from the show Sherlock (2010) which is also by Steven Moffat. However, due to copyright reasons (they would have had to pay David Arnold) the tune is not the same music from Sherlock.
4. Neve McIntosh played two other Silurians, Alaya and Restac, in Doctor Who: The Hungry Earth (2010) and Doctor Who: Cold Blood (2010).
5. The Doctor impersonates Sherlock Holmes, a role already played by two previous Doctors - Tom Baker and Peter Cushing. And then, of course, Steven Moffat, the head writer of Doctor Who (2005) since 2010 also co-wrote the Sherlock (2010) TV series.
6. The episode saw several major design changes for the series, such as a redesigned TARDIS interior, a new title sequence and variation of the theme tune.
7. For the first time since the series' revival, the face of the Doctor appears in the title credits. The Doctor's face had first appeared during Patrick Troughton's era in the 1960s.
8. Vastra, Jenny, and Stax first appear in Doctor Who: A Good Man Goes to War (2011).
9. The Great Intelligence's line, "Now the dream outlives the dreamer and can never die," echoes what was written about the Weeping Angels: "What if we had ideas that could think for themselves? What if, one day, our dreams no longer needed us?"
10. Matt Smith described his Victorian-style costume as "a bit Artful Dodger meets the Doctor". Steven Moffat described the new outfit as a "progression" as the Doctor was in "a different phase of his life now" and felt more "grown-up" and fatherlike.
11. This was the first Christmas special to be filmed in BBC Wales' new Roath Lock studios.
12. Steven Moffat compared the withdrawn Doctor seen at the onset of the episode to the first appearances of the First Doctor in 1963 and the Ninth Doctor in 2005. He also attributed the idea of a retired Doctor to a plot proposed by Douglas Adams in the 1970s, but rejected by the production team at the time.
13. This episode has individually stylized opening credits: following the revamp of the opening title sequence, the time vortex has changed to a vibrant red with several nebula-like effects, and the title logo resembles a fresh snowfall in color and pattern.
14. Richard E. Grant previously played The Doctor in Comic Relief: Doctor Who - The Curse of Fatal Death (1999) and voiced The Doctor in Doctor Who: Scream of the Shalka (2003).
15. The glasses the Doctor is wearing in this episode (and the following few) are Amy's old glasses.
16. Some consideration was given to providing no on-screen title at all, since it was thought that the title sequence might be held off until the end of the episode, illustrating the Doctor's return to his old self.
17. This episode takes place in December 1842, from December 23 to December 25, 1892 and in the 2010s.
18. The TARDIS on the cloud was achieved through a mix of fog on the studio floor and post-production special effects.
19. Director Saul Metzstein explained that it was difficult to achieve the desired look for the snowmen. The first ones he likened to Zippy from Rainbow (1972) which was too "cute" of an appearance, and so the effects team created more menacing CGI faces.
20. The original concept for the new companion was that she would be a Victorian governess named Beryl. Over the next few months, however, the production team reconsidered the difficulty of writing for a regular character who was more than a century behind the viewing audience.
21. "The Snowmen" was influenced by The Dark Knight Rises (2012). The Doctor has become a recluse and is no longer interested in traveling through time and space and fighting evil, but is forced out of seclusion to fight The Great Intelligence and The Snowmen.
22. It was originally planned that this special would be the first episode to not have an opening credits sequence, instead opening with the title superimposed over a scene. In pre-production it was decided to have one, and a newly redesigned credit sequence and theme arrangement was devised.
23. Steven Moffat was also uncertain about an epilogue featuring the 2013 version of Clara, which appeared and disappeared between several drafts. When it was finally decided to preserve this scene, a false ending was concocted to safeguard the surprise; this saw Vastra and Jenny comment on how the events of the story had reinvigorated the Doctor.
24. The series was in the process of relocating from its former studio facilities at Upper Boat to its new permanent home at Roath Lock in Cardiff Bay. There was no way to preserve the TARDIS set designed by Edward Thomas for Doctor Who: The Eleventh Hour (2010), and so this became an opportunity to give the current production designer, Michael Pickwoad, the chance to leave his own mark on the TARDIS interior. Steven Moffat indicated that he wanted to move away from the organic feel of recent console room sets and instead embrace the idea of the TARDIS as a machine, citing in particular the look of the time machine during the 1970s.
25. The inspiration for Doctor Who: The Snowmen (2012) was inspired by a storyline that was pitched by Douglas Adams called "The Doctor Retires".
26. Early drafts incorporated another ingredient to the mystery of the Snowmen, associating them with sightings of riderless hansom cabs. There were also more flashbacks to Dr Simeon's early life, and medical equipment used to try to revive Clara after her fall was implied to be responsible for Strax surviving the events of Doctor Who: A Good Man Goes to War (2011).
27. The Great Intelligence is voiced by Sir Ian McKellen. McKellen also played the wizard Gandalf in The Hobbit: An Unexpected Journey (2012), which also featured former Doctor Who star Sylvester McCoy.
28. A pond is an important part and word for this episode. Amy Pond's last episode was the one before this.
29. Several elements of The Snowmen were discarded in editing. This included material involving a little boy (Max Furst) and his mother (Devon Black) who live near the site where Simeon's labourers were working, and suggestions that the monsters were snowmen built the previous year given new form. The coming of the Ice Governess was originally foretold when a formation appeared in the middle of the Latimers' pond which resembled an upthrust arm. Also deleted was an inscription on Clara's tombstone: "Remember me. For we shall meet again."
30. Christopher Nolan's 2012 film "The Dark Knight Rises" is considered an influence behind the 2012 Christmas Special The Snowmen. The Doctor, now a recluse and no longer interested in traveling across time and space and fighting evil, is forced out of seclusion to fight The Great Intelligence and The Snowmen. In "The Dark Knight Rises", Bruce Wayne, now a recluse, is forced to become Batman again, to do battle with Bane and Talia al Ghul.
31. The story was originally called The Snowman.
32. With the casting of Matt Smith in Morbius (2022), four of the performers in this episode have been in Marvel universe projects. Jenna Coleman had already appeared as Connie, Bucky's date, in Captain America: The First Avenger (2011). The villain of the episode, Dr. Simeon, was played by Richard Grant, who would be cast in Logan (2017) as Dr. Rice, as well as Classic Loki in Loki (2021). The voice of the Great Intelligence was provided by Ian McKellen, who had been portraying Magneto in the X-Men films since 2000. This was the first Dr Who episode to feature Matt Smith without Karen Gillin, who portrays Nebula in the Guardians of the Galaxy and Avengers movies, but her death at the hands of the Weeping Angels in the series' previous episode is the cause for the Doctor's depression and apathy in this episode.
33. A further link to Sherlock Holmes would occur when Sir Ian McKellen, who plays the voice of The Great Intelligence would play the retired Sherlock Holmes in Mr Holmes.
34. In the narrative behind The Doctor becoming an recluse and no longer being interest in traveling through time and space and battling evil aliens and fighting evil. The Doctor had gained and lost a lot of friends throughout his 11 lives and on his travels across time and space and the loss of Amy and Rory really pushed The Doctor too far causing The Doctor to become disillusioned and giving up on saving the world.
35. The date of birth that can be read on Clara's tombstone is 23 November 1866. 23 November 1963 is the release date of the first episode from the classic era, Doctor Who: An Unearthly Child (1963).
36. The set where the Doctor first meets Clara is the one used for the hidden Sanctuary so it bookends Clara.

The Bells of Saint John

1. While searching for the mysterious blue box, and spotting it in Southbank, Mahler says "Are we sure this time? Earl's Court was an embarrassment." In real life, there is a Blue Police Box outside the Earl's Court Underground Station - the only one left in London.
2. The author of the book that Artie is reading is Amelia Williams, the married name of the Doctor's previous companion, Amy Pond.
3. This is only the second time since the revival the TARDIS' police box phone has rung. The other time was for the Ninth Doctor in Doctor Who: The Empty Child (2005)
4. After seeing the book Summer Falls Clara says that Eleven is the best and that they will cry their eyes out - a subtle reference for Matt Smith, the Eleventh Doctor, and the emotional stories he is associated for.
5. "The Bells of Saint John" is a reference to the ringing TARDIS. The TARDIS of the Eleventh Doctor has the Saint John (Ambulance) image on the door.
6. The password for the Maitland family's wi-fi, 'rycbar123' is both an acronym of 'run you clever boy and remember' and a reference to the fact that this is the third version of Clara to appear.
7. Steven Moffat described the premise as "the traditional 'Doctor Who' thing of taking something omnipresent in your life and making it sinister, if something did get in the Wi-Fi, we'd be kind of screwed. Nobody had really done it before, so I thought, 'It's time to get kids frightened of Wi-Fi!'"
8. To keep the reappearance of the Great Intelligence a surprise, Richard E. Grant was not credited in Radio Times. He was, however, originally listed on the BBC website, but was subsequently taken down.
9. A long scarf similar to the one worn early in the fourth Doctor's run is seen by the home security monitor inside Clara's house.
10. Angie has a friend called Nina. Nina is what Oswin Oswald nicknamed Rory in The Dalek Asylum.
11. The book by Amelia Williams was initially called One Deadly Summer before becoming Summer Falls (a version of which, ghost-written by James Goss, would be published online and later as part of a print anthology).
12. Steven Moffat denied that his intention was to give a warning about technology, but rather tell an adventure story about a "new way [for aliens] to invade" based on something viewers were familiar with.
13. People's essences being trapped in screens also occurred in The Idiot's Lantern (2006). In this previous episode it was due to an entity called The Wire taking people's faces through TVs.
14. This story gives a new logo for the second half of series seven, a weathered metallic texture. Unlike the first half of the season, in which the logo changed from episode to episode, the logo remained constant for the remainder of Series 7. Similarly, the new theme tune of the series is slightly modified from its previous arrangement, omitting the "shimmering" musical flourishes and electrical hissing noises heard in its first variation.
15. The inclusion of the Shard skyscraper near London Bridge as the headquarters of Cloud Incorporated was intended to give the story a highly contemporary feel; the edifice would not be opened to the public until February 1st, 2013.
16. The title of this episode is a reference to the phone incorporated into the TARDIS police box disguise, and to the "St John Ambulance" logo on the door of this version of the TARDIS. The "Bells" part is referring to the police box phone ringing. It is also a reference to the nursery rhyme Oranges and Lemons.
17. Producer Marcus Wilson suggested that the episode be an "urban thriller", as the story would already be set in contemporary London to introduce Clara and the Wi-Fi monsters.
18. Originally, there was no reference to Miss Kizlet's client, but in later drafts the Doctor learned over the course of the story that this was the Great Intelligence; only latterly was this made known to the audience but not the Doctor.
19. This episode takes place in 1207 and 2013.
20. The character of Clara Oswald is named after Elisabeth Sladen, who played famous companion Sarah Jane Smith. Elisabeth's full name was Elizabeth Claira Heathe Sladen.
21. One major edit came towards the end of the episode, in which the Doctor would have been seen contemplating images of Oswin and the Victorian-era Clara when the TARDIS phone rang again; a whispered female voice on the line then implored the Doctor to trust Clara and take her with him. This had replaced an earlier version which took place after Clara was attacked by the Spoonhead, with the voice telling the Doctor, "Run you clever boy. And save her."
22. Until a very late stage, the Doctor found a sheet of passport photos in Clara's travel book rather than a leaf; this was changed to tie into the next story to go before the cameras, Doctor Who: The Rings of Akhaten (2013).
23. Wi-fi networks were still new technology but were fast becoming omnipresent, and Steven Moffat had been struck by the way they would pass in and out of the range of his laptop as he rode the train between London and Cardiff. This led to the notion of a rogue wi-fi network.
24. Clara states that the bad guys, later named as Cloud Inc., are on the 65th floor of The London Shard. While The Shard has many floors of offices the 53rd through 65th floors are residential.
25. The title was originally announced as The Bells of St John, in keeping with the actual abbreviated spelling of "St John" on the logo.
26. For a time, it was thought that Kate Stewart might accompany the UNIT troops who arrest Miss Kizlet.
27. Steven Moffat said that the episode was "an action roller coaster" rather than a story intended to be scary.
28. The bike used to ride the Shard is the (British) Triumph Scrambler.
29. Steven Moffat compared the story's style to James Bond and The Bourne Identity (2002).
30. The first appearance of Angie and Artie.
31. The alien races the Doctor points out to Clara include a Hooloovoo, a nod to Douglas Adams who described them as "super-intelligent shades of the color blue" in "The Hitchhiker's Guide to the Galaxy". The Doctor also mentions a "Pan-Babylonian", which is an academic joke. Panbabylonianism is a school of thought from 19th century Germany that considered the cultures and religions of the Middle East and civilization in general to be ultimately derived from Babylonian myths. The "Lucanians" were actually an Italic tribe from the 5th century BC.
32. Calvin A. Dean was seen for a minor role.

The Rings of Akhaten

1. In the market on Akhaten, the Doctor points out a Hooloovoo, a race first described in The Hitchhikers Guide To The Galaxy books as a "Super-intelligent shade of the colour blue".
2. When the Doctor and Clara first arrive at Akhaten he mentions that he once brought his granddaughter there. This is a reference to Susan, a companion of the First Doctor and the Doctor's granddaughter.
3. Ellie Oswald is shown to have died on March 5, 2005, the same date as the events of Doctor Who: Rose (2005). This possibly suggests that Clara's mother was killed in the Auton invasion.
4. The Doctor at one point mentions how the elements came together to form "shoes, and ships, and sealing-wax, cabbages, and kings" This is a direct reference to "The Walrus and The Carpenter" from "Through the Looking-Glass and What Alice Found There" by Lewis Carroll.
5. Originally the resolution was to be the Doctor defeating the planet with his speech, which Neil Cross likened to "facing down one of Lovecraft's Old Gods: an alien so alien that it's practically a supernatural being." Steven Moffat pointed out that the Doctor had given similar speeches before and was more interested in Clara saving the day. After thinking about it for a while, Cross realised he could incorporate the leaf into the solution.
6. According to Matt Smith, there were "between 50 and 60 prosthetic aliens" in a scene set in an alien market.
7. The Doctor features minimally in the first act because Matt Smith was busy filming pick-ups or reshoots for Doctor Who: Nightmare in Silver (2013).
8. In his speech, the Doctor includes the line "I walked in universes where the laws of physics were devised by the mind of a madman". This is a reference to the serial 'The Three Doctors' in which the Time Lord Omega has been banished to the antimatter universe where his will is the only thing that maintains reality, but his exile has caused him to become insane.
9. The basic plot has commonality with the Doctor Who Magazine comic story, Thinktwice. As in this story, the Tenth Doctor fights an enemy that takes memories, and he proposes to defeat that enemy, the Memeovax, by "overloading it" with his own memories.
10. Much of the episode was constructed around talks of what could be created with limited resources. For example, Neil Cross recalled that producer Marcus Wilson called him and asked, "We've always wanted to have a speeder-bike like in Star Wars: Episode VI - Return of the Jedi (1983)and we know how to do it inexpensively, so can you get one into the story?" However, Cross felt that the speeder-bike ended up having more in common with Flash Gordon (1980).
11. Neil Cross was chosen to write this episode based on the strength of Doctor Who: Hide (2013).
12. The episode originally had a different pre-credits sequence, which consisted of a long scene in the kitchen in which Clara informs the Doctor she cannot come and travel with the Doctor because she has responsibilities to her job, and the boy she takes care of asks if the Doctor is her boyfriend. Neil Cross's intent was to juxtapose this "mundane" scene with the vast scale of the planet. However, Steven Moffat thought that at the time in the series the Doctor should be investigating Clara through her parents and Cross revised to include the leaf, an idea Moffat approved of.
13. The Doctor quotes two lines from Blade Runner (1982):"I've seen things you wouldn't believe," and, "Home again, home again, jiggidy-jig."
14. Millennium FX's Neill Gorton remarked that he had "always wanted to do a scene like the Star Wars (1977) cantina" and had worked on different moulds in his spare time in case they could be used in the future, as making thirty different aliens at one time would be out of the budget.
15. Jenna Coleman named this as one of her favourites of the second half of the seventh series, as it was the first adventure for Clara which allowed the audience to watch the story "[begin] again".
16. The concept behind having the episode based around an alien planet occurred to Steven Moffat, Caroline Skinner, and producer Marcus Wilson when realising they had done big location pieces in the first half of the series with Doctor Who: A Town Called Mercy (2012) and Doctor Who: The Angels Take Manhattan (2012), but had none for the second half.
17. Akhaten was originally referred to as Akhet, a name which survived in references to the Sun Singers of Akhet. It was an homage to both the unknowable alien gods depicted in the macabre stories of H.P. Lovecraft, and the anthropomorphised moon in A Trip to the Moon (1902).
18. Most of the aliens in the bazaar are made of bits of props left over from previous Doctor Who (2005) aliens or ones from other BBC shows.
19. When the Doctor is in Blackpool he reads the 1981 Summer Special issue of the children's comic book "The Beano". The same issue was given to the Thirteenth Doctor's new companion (Graham, played by Bradley Walsh ) in the July 2018 trailer for series eleven.
20. Unlike the previous episodes of Series 7, this episode does not introduce a new variation of the Doctor Who logo.
21. The Doctor tells Clara that he visited Akhaten before with his granddaughter Susan. Obviously, the 1st Doctor and Susan visited Akhaten after they left Gallifrey and before meeting Ian and Barbara in Trotter's Lane in 1963.
22. The glasses the Doctor is wearing are Amy's old glasses.
23. Early on, Neil Cross' script (a first draft of which was completed in early October) bore the functional title "Alien Planet". This reflected the author's process of first conceiving the sentient planet Akhaten with its two concentric ring systems (where the pyramid-like Apex Temple lay in the inner ring, and the market asteroid of Tiaanamaat lay in the outer), and developing its people and their religion, before building the plot around this setting.
24. The flashback was the first scene to be filmed.
25. This episode takes place in 1981, 2005 and 2013.
26. Virtually all of this story was filmed at the new Roath Lock studio.
27. You see the Doctor read a Magazine: The Beano...covering an item about the "Dolphinarium". This is an actual theme park in the Netherlands. Although it hasn't had to do anything with the scene showing on the cover. It's a huge aquatic waterpark. Incl. the opportunity to swim with dolphins and other sea creatures.
28. The merchants use objects of sentimental value as currency instead of paper money. The Doctor lies to Clara saying he has nothing on him except for his sonic screwdriver. He has his former companion Amy Pond's glasses, which he wore in the previous scene and placed inside the same jacket pocket as the sonic screwdriver.
29. When Clara and her father Dave visits her mother Ellie's grave. Ellie's gravestone states that Clara's mother died on 5th March 2005 and that her death remained a mystery. The 9th Doctor first met Rose Tyler, Jackie Tyler and Mickey Smith in March 2005 in Doctor Who: Rose (2005) and it's most likely, Ellie was killed in the Auton attack in London that occurred that month.

Cold War

1. Both of the two main guest stars have been in the running to play the Doctor. David Warner was suggested by Pip Baker and Jane Baker for the Seventh Doctor prior to the casting of Sylvester McCoy. Liam Cunningham was seriously considered for the Eight Doctor in Doctor Who (1996).
2. The things that are pulled out of the Doctor's pockets when they are searched are a Barbie, a ball of twine, a toffee apple and the sonic screwdriver.
3. Liam Cunningham was the 1st and only choice for Captain Zhukov.
4. In an early draft the character of Professor Grinsenko was a villain.
5. Steven Moffat had originally been hesitant to bring back the Ice Warriors, worrying that they were seen as "the default condition for what people thought of as rubbish Doctor Who (1963) monsters - things that moved very, very slowly and spoke in a way that meant you couldn't hear a word they said." Mark Gatiss, however, was a fan of the Ice Warriors' stories and had been campaigning to bring them back. In a phone conversation with Moffat that was originally supposed to be about Sherlock (2010), Gatiss pitched new and "very clever ideas" of what to do with the Ice Warriors, and Moffat agreed. What sold Moffat were the submarine setting and seeing what the Ice Warriors looked like underneath their suits. Gatiss felt that the Ice Warriors had a lot of gaps in their timeline and had not been featured in a while, which allowed a lot of room to explore them.
6. It had been decided that the submarine would be realised as a model, rather than as computer animation, to provide a better sense of weight and presence.
7. David Warner approached Mark Gatiss about a possible role in the series.
8. The submarine was Mark Gatiss's idea. He felt that Doctor Who called out to be set on a submarine. Executive producer Caroline Skinner described the story as "Letting a huge Ice Warrior loose at the heart of a classic The Hunt for Red October (1990) style submarine movie."
9. For the submarine setting, the cast would be sprayed in between every take.
10. Many of the character names had some significance: Sergei Stepashin was briefly Prime Minister of Russia under President Boris Yeltsin, Eugene Onegin was a verse novel by Alexander Pushkin serialised from 1825, and Captain Zhukov was an homage to General Georgy Zhukov of the Red Army, who had been instrumental in the liberation of Eastern Europe from the Axis powers during World War II.
11. This episode takes place in 1983.
12. Mark Gatiss chose the time period because he was "kind of obsessed" with the Cold War, and felt that there were several times in the 1980s where the danger was close. Gatiss also described "Cold War" as a "love-letter" to the base-under-siege stories that were common during Patrick Troughton's time. The episode even contains a reference to "The Krotons", which was the last time the TARDIS's HADS had been mentioned.
13. Skaldak's costume was made of flexible urethane rubber.
14. This episode features several main cast members of Netflix's The Crown (2016). Matt Smith (The Doctor) played Prince Phillip, the Duke of Edinburgh, in seasons 1 and 2 of the series. Tobias Menzies (Lieutenant Stepashin) took over the role from Smith, playing an older Prince Phillip in seasons 3 and 4. Josh O'Connor (Piotr) also joined the cast in seasons 3 and 4 as Prince Charles, the son of Menzies' Philip.
15. The scenes in which the characters are drenched in water were achieved by constantly pouring "gallons and gallons of water" on the cast. Jenna Coleman found the experience fun, while Matt Smith said that it made acting easier. Coleman said, "The whole make-up process was reversed as they would damp us down in the morning and rub my mascara off!"
16. 1983 was indeed a point in which the the Cold War could have very easily run hot, due to the (alluded to) Able Archer '83 exercises that terrified the already paranoid Soviets. There were even several close calls throughout the year, including one famous incident where only the cool head of a Soviet radar operator deciding that the missile that appeared on his screen was not a launch but most likely an equipment malfunction prevented a full-scale nuclear launch. On the 1st of September 1983, a Soviet fighter jet even shot down a Korean passenger airliner which accidentally strayed into their airspace, killing 269 people.
17. Unlike some other returning monsters, the Ice Warriors were not heavily redesigned. Mark Gatiss insisted upon keeping the fundamentals of the original and Steven Moffat explained that the original design was not well-known enough to put a new spin on it, and so Skaldak's shell is just a "super-version of the original".
18. In the original script, the Ice Warrior Skaldak was a more complex creation: he was a time traveller from the thirty-first century who planned to provoke a nuclear war which would wipe out humanity, thereby preventing mankind from dominating Mars in his era. After mind-controlling the Doctor's new companion (at this point, a Victorian-era governess named Beryl) to further his scheme, Skaldak was ultimately killed by one of the Russians. The surviving crew escaped to a British sub, the Redoubt, while the sinking Russian vessel was destroyed by the water pressure.
19. The new Ice Warrior costume was constructed by Neill Gorton and his team at Millennium FX. While respecting Mark Gatiss' desire that this should hew as closely as possible to the original Ice Warrior design, Gorton effected some changes to make the armour more credible: the hands had digits rather than clamps, the proportions were better balanced, and the tufts of fur were removed. (In some ways, the overall conception of the new Ice Warrior reflected Brian Hayles' original vision of the Martians as being partly cybernetic.) However, to accommodate such a massive costume - as well as to provide more space for the cast and crew - scenes aboard the Firebird would have to be largely realised in the studio, since a real submarine would be far too cramped.
20. This is the first time an Ice Warrior has been seen "out of uniform" on television.
21. All camera shots featuring the exterior of the submarine under the water were made using scale models in front of a blue screen.
22. The interior of the TARDIS isn't seen in this episode.
23. Both Liam Cunningham and Tobias Menzies play important characters in Game of Thrones (2011): Ser Davos Seaworth and Lord Edmure Tully, respectively.
24. Josh O'Connor played Prince Charles in seasons 3 & 4 of The Crown. Prince Charles is the son of Prince Phillip, played in seasons 1 & 2 by Matt Smith and 3 & 4 by Tobias Menzies.
25. Clara hears David Warner's character singing and she mentions karaoke , David Warner's character tells her she speaks Russian wonderfully but strange. The character being a Russian Scientist/ professor would know of his Japanese counterparts use of karaoke in Japan in 1983 as it was quite prevalent very popular and surely a man of his class would pride himself knowing of their quirks as part of information. He would have traveled to other countries to study, attend symposiums to learn research developments and those also who were friendly to Russia while not being stuck in culture loss. His having a Walkman with western music shows his cross cultural access was very up to date for 1983, Ultravox and Duran Duran were very popular.
26. Several of the character names evolved during the adventure's development: the lieutenant was originally Tsarsko instead of Stepashin; the name Stepashin was earlier applied to the political officer (later Belevich); and Serovian, not Onegin, was the navigator.
27. "Mars will rise again" is a nod to Futurama.
28. Liam Cunningham (Captain Zhukov) also plays a seagoing captain (albeit a smuggler, among other things) in Game of Thrones as Davos Seaworth.

Hide

1. The spacesuit The Doctor wears is the same one he first uses in Doctor Who: The Impossible Planet (2006) and Doctor Who: The Satan Pit (2006) and then reused in Doctor Who: 42 (2007) and then again in Doctor Who: The Waters of Mars (2009).
2. Neil Cross wanted to write "a really old-fashioned scary episode of Doctor Who (2005) targeted especially at children nine to twelve, which was how he remembered Doctor Who (1963) at that age. He stated that "time travel and ghosts are echoes of one another. What is a ghost, if not a fragment caught in time?" He aimed to show suspense and tension, as he felt it was more terrifying than "full-on shock horror blood and gore".
3. The Doctor visited Metabilis 3 and had fun with blue crystals in "Planet of the Spiders".
4. The Crooked Man's movements were done in reverse and then played forward, to give it an unnatural movement.
5. This was the first episode filmed by Jenna Coleman as a series regular, but screened as the fourth episode in series 7b.
6. Matt Smith was ill with flu when making the TARDIS scenes.
7. Director Jamie Payne had Neil Cross's children be "monster consultants" during filming and evaluate if it was scary enough.
8. When The Doctor is unraveling the mystery of The Crooked Man he says "Birds do it, bees do it, even educated fleas do it". This is a line from the song "Let's Do It, Lets Fall In Love" by Cole Porter.
9. Subsequent to filming her appearance in this episode, Jessica Raine was cast as Doctor Who (1963)'s original producer, Verity Lambert, in An Adventure in Space and Time (2013).
10. "Hide" was intended to be a "very small, very restricted ghost story", but he was asked to make it bigger in the end. The different universe was present, but it was "smoke and mirrors" and the climax originally took place in the house, just in daylight and in the alternate world.
11. When Clara and The Doctor are scared from the creature making a loud noise, Clara tells The Doctor that he doesn't have to hold her hand, to which The Doctor replies, "I'm not holding your hand!" This is a reference to the 1963 film, The Haunting (1963) which contains a scene where the films main character, Eleanor is in the dark and thinks her friend is holding her hand, but when the lights come on it is revealed no one is there (it was a ghost) to which she says "Whose hand was I holding?"
12. Caliburn House was named after King Arthur's sword in the writings of Geoffrey of Monmouth, which later evolved to become Excalibur.
13. Neil Cross was inspired by The Quatermass Experiment (1953) and its sequels, and originally intended to have the Doctor meet Bernard Quatermass, though this was not possible, for copyright reasons. Cross was also inspired by Quatermass writer Nigel Kneale's The Stone Tape (1972), which was why he set the story in the 1970s.
14. To Neil Cross' surprise, Steven Moffat also encouraged him to expand the scale of the script. Cross had set the entire adventure in and around Caliburn House. Even the scenes in the Crooked Man's realm were confined to Caliburn House, thereby minimising budgetary requirements. It was Moffat who suggested that much of this material could be relocated to an eerie wood.
15. This story is set in the year 1974, as stated by Alec Palmer as he records his notes.
16. The script process involved no face-to-face meeting, as Neil Cross lives in New Zealand. However, he flew in with his family to watch the filming
17. The idea of the Crooked Man was something Neil Cross said lurked in his imagination.
18. Neil Cross said that Jessica Raine and Dougray Scott were good at filling out their characters, as he found it difficult to fully "evoke the history of a quite complex relationship" between their characters with just the script
19. Jenna Coleman was uneasy about diving straight into the middle of Clara's adventures with the Doctor before filming her introduction (a circumstance created in part by the lateness of the script for Doctor Who: The Snowmen (2012)) but Steven Moffat and Jamie Payne both worked to assuage her concerns.
20. Clara declares that whiskey is the 11th most disgusting thing ever invented (while being 11's companion)
21. The opposite of bliss is said to be Carlisle. That UK city has long been considered dull and is listed as the city with the least to offer tourists.
22. Working titles for the episode were Phantom of the Hex and The Hider in the House.
23. Jessica Raine had also worked with Matt Smith before on a play.
24. This episode takes place on November 25, 1974.
25. This episode takes place on November 23, 1974.
26. The love story twist was added in later, because Steven Moffat felt the monster should be more fleshed out, and Neil Cross chose to mirror the love plot between Emma and the Professor.
27. The Doctor decides to enter the pocket universe and says they need a strong rope, blue crystal, and Kendal mint cake. Kendal mint cake is a high energy soft candy made of sucrose, dextrose and peppermint oil which has long been popular among British mountaineers. The harness he wore was not climber's gear but a military LLP Mk1 low level parachute harness with the rope tied to a reserve chute D ring.
28. When Clara is explaining to Emma that the professor is giving off signals that he is interested in Emma, Emma asks how she knows that. Clara explains that all the signs are there and they "stick out like a big chin." When Clara first meets the Doctor in the episode, Doctor Who: Asylum of the Daleks (2012), she keeps commenting on calling the Doctor's big chin.
29. In the original script, The Hex was the otherworldly dimension in which Hila was trapped, and it was the prison of the Lost Lord, an ancient Time Lord also called the Revenant of Anathenon who had become snared in the Hex so long ago that he was now just a bogeyman of Gallifreyan legend. The Lost Lord sought to tempt the Doctor into the Hex and feed on him, enabling him to return to the normal universe where he would begin absorbing all of time. The Lost Lord element of the tale was discarded, to be replaced by the more straightforward Crooked Man. (The Hex terminology would survive until recording, before being lost in editing.) However, Steven Moffat became concerned that the Crooked Man was now too shallow a concept. He worked with Neil Cross to develop the idea of the two Crooked Men and the love which bound them, reinforcing themes already present in the storyline.
30. In this episode the Eleventh Doctor says, "It's the oldest story in the universe. This one or any other. Boy and girl fall in love, get separated by events - war, politics, accidents in time. She's thrown out of the hex or he's thrown into it. Since then they've been yearning for each other across time and space. Across dimensions. This isn't a ghost story, it's a love story." This is a direct reference and confirmation to the Doctor's relationship with Rose Tyler. In S1 the Ninth Doctor and Rose meet and fall in love. In S2 the Tenth Doctor and Rose are separated by accident when Rose is pulled into a parallel universe (the first episode of this two parter being called Doctor Who: Army of Ghosts (2006)). S3 is predominately about The Doctor missing Rose and grieving her absence. S4 is Rose fighting her way across dimensions to get back to him.
31. Before Doctor and Clara start to explore the house, Emma says "The music room is the heart of the house" out of the blue. This sentence looks completely out of place here. However, in the next episode's ending ("The Journey to the Centre of TARDIS"), Doctor will solve a huge crisis by finding the right music at the heart of TARDIS. Since Emma is a psychic, this seems to be her warning for the future episode's events.
32. This episode bears a passing resemblance to "The Man Who Walked Home," a short story by James Tiptree Jr. (Alice Sheldon) that appeared in a 1977 edition of Andromeda.
33. When The Doctor travels back in time to photograph the exact same spot, he tells Clara that they have travelled "about 6 billion years" into the past. This is a continuity error, since in Series 3: The Runaway Bride, the creation of the Earth occurred 4.6 billion years prior.

Journey to the Centre of the TARDIS

1. When Clara is in the Doctor's room of trinkets she finds the cot the Doctor told Amy he slept in as an infant. She also picks up one of the toy TARDIS' Amy made as a child.
2. When Bram removes part of the TARDIS console, the past leaks through. Heard, in order, are the voices of Susan Foreman in Doctor Who: An Unearthly Child (1963), the Third Doctor and Jo Grant in Doctor Who: Colony in Space: Episode One (1971), the Eleventh Doctor and Idris in Doctor Who: The Doctor's Wife (2011), the Fourth Doctor in Doctor Who: The Robots of Death: Part One (1977), the Ninth Doctor in Doctor Who: Rose (2005), Martha Jones in Doctor Who: Smith and Jones (2007), Amy Pond in Doctor Who: The Beast Below (2010), Ian Chesterton in Doctor Who: An Unearthly Child (1963), and the Fifth Doctor in Doctor Who: Time Crash (2007).
3. This episode is only the third time since the shows revival that the areas of the TARDIS outside the control room have been shown.
4. The rooms that Clara comes across on her initial exploration of the TARDIS are the Doctor's workroom, an observatory, an indoor swimming pool, and a library.
5. This is the first time the whole of the Eye of Harmony has been seen.
6. This is the first televised story to include the word "TARDIS" in its title.
7. Steven Moffat gave the concept of an episode discovering the centre of the TARDIS to Stephen Thompson. Thompson explained that this was because Moffat was "haunted" by Doctor Who: The Invasion of Time: Part Six (1978), which was set on the TARDIS but used hastily-constructed sets. Thompson was also interested in mathematics and remarked, "anything involving multi-dimensional geometry gets me excited".
8. Although the action was normal in the classic series, this is the first time since the series restarted that the Doctor has closed the TARDIS doors from the console, rather than manually shutting them or occasionally closing them by snapping his fingers.
9. The TARDIS in the opening credits shakes to match the captured TARDIS in the magno-grab.
10. Sarah Louise Madison (Time Zombie) played a Weeping Angel.
11. Ashley Walters managed to get in trouble with the producers on the first day of filming when he tweeted a picture of himself in his costume in his trailer with the word "space". The picture was immediately removed.
12. Steve Thompson initially thought back to his days as a teacher, and came up with a story in which the TARDIS crashed into a school trip, unleashing a gaggle of teenagers into the time machine who cause it to malfunction. Steven Moffat disliked this idea, and so Thompson suggested replacing the students with a salvage team.
13. The title is an obvious nod to the classic 1864 science fiction novel "Journey to the Centre of the Earth" by Jules Verne.
14. In early versions, Clara came across a chamber containing the leftover belongings of all of the Doctor's previous companions; this was eventually simplified to the storeroom in which she finds one of the young Amy Pond's model TARDISes (from Doctor Who: Let's Kill Hitler (2011)) and the Doctor's cot (from Doctor Who: A Good Man Goes to War (2011)).
15. Early on, when The Doctor's going to put the TARDIS in 'basic' for Clara, the key he turns says 'SMITHS' on it. This iteration of The Doctor being portrayed by Matt Smith. Or more likely, a nod to the Doctor's oft used pseudonym, John Smith.
16. While Steve Thompson was writing the episode, it was intended to be the sixth episode of the spring run. As such, it ended with a coda featuring Clara's charges, Angie and Artie Maitland, confronting the time travellers about their adventures and leading into episode seven, Doctor Who: Nightmare in Silver (2013). However, as Thompson's story was moved to the fifth spot, the epilogue was rewritten and shifted to the eventual episode six, Doctor Who: The Crimson Horror (2013).
17. At seven words long, this episode shares the record for the longest televised story title to date with Doctor Who: The Doctor, the Widow and the Wardrobe (2011), which also is a title inspired by a book/film.
18. This is the first episode since "The Web Planet" to use the "British" spelling of a word "Centre" versus "Center", although other episodes don't use words that have different spellings in Britain and America.
19. For a time, the Van Baalens' salvage career was motivated by a severe metal famine in the area.
20. Nearly all of the episode was filmed at Roath Lock studio home. An exception to this was the first day of recording, September 4th, when the deck of the Hornet was actually a warehouse on Celtic Way in Newport.
21. In the final conversation between Clara and the Doctor, you can tell there are two distinct takes making up the scene because Clara's hair consistently shifts between being on either side of her head when the camera is facing her and being all pulled over her left shoulder and even off her neck when the camera's behind her.
22. Originally, the third van Baalen brother was named Sander rather than Tricky - meant to be short for "Electricky" - and was not an android, while Gregor was disfigured and had numerous metal attachments.
23. While in the Library, Clara comes across a book titled The History Of The Time War. She then opens the book to an undetermined page and says "So that's who." Leading one to think she knows who the Doctor is.
24. The Sixth Doctor had previously used the countdown timer as a fake self-destruct in Doctor Who: Attack of the Cybermen: Part Two (1985)

The Crimson Horror

1. Rachael Stirling, who plays Ada, the blind daughter of the villainous Mrs. Gillyflower, played by Diana Rigg, is also Rigg's daughter in real life.
2. "Thomas Thomas" gives directions like a GPS. Tom Tom is a manufacturer of GPS devices.
3. This is the first time that Diana Rigg speaks in her native Doncaster accent.
4. The episode was specially written for mother and daughter Diana Rigg and Rachael Stirling.
5. When getting out of the TARDIS, Clara points out the Doctor's habit of not turning up where they want, to which the Doctor replied he once spent "A Hell of a long time trying to get a gobby Australian to Heathrow airport." This is a reference to the Fourth and Fifth Doctor's companion Tegan Jovanka.
6. This is the 100th episode since the return of Doctor Who in 2005.
7. The front door of Madame Vastra's house is painted a glossy version of TARDIS blue.
8. Vastra's client continually faints when exposed to any unexpected or shocking events. This is a satire of how women were culturally perceived to act in the Victorian era.
9. Sweetville is based on the real-world model village of Saltaire, Yorkshire, founded in 1851 by wool industrialist Titus Salt. Titus also had a daughter called Ada, after whom a street in the village is named. Sweetville's name may also reflect the model village of Bournville whose name was later used for a brand of sweet, a chocolate bar.
10. Matt Smith was delighted to see Vastra, Jenny and Strax return to the series, and based the Doctor's relationship with Strax on the interplay between Blackadder and Baldrick in Blackadder (1982) and its sequels.
11. Diana Rigg had never seen Doctor Who (1963). She was persuaded after viewing a showreel of classic villains from the series assembled by Michael Dennis, stage manager on The Recruiting Officer, a play she was appearing in at the time.
12. Steven Moffat originally planned to write this episode himself, but found he was unable to and turned it over to Mark Gatiss.
13. Mr Sweet was derived from "the repulsive story of the red leech", an untold adventure of Sherlock Holmes mentioned at the start of The Adventure Of The Golden Pince-Nez (1904).
14. This story marks the first time in the revived series that a companion's associates have successfully deduced the person's time-travelling affairs with the Doctor's on their own, along with the Doctor's ability to time-travel, without questioning the Doctor directly or getting a firsthand experience of the TARDIS.
15. The unnatural slurry which caused the eponymous "horror" was suggested by Carry on Screaming! (1966), in which a chemical sludge turned young women into mannequins.
16. Recording was paused for two weeks to facilitate various promotional engagements, including a major panel at the San Diego Comic Con.
17. Sweetville was inspired by real planned communities in the North, such as Saltaire (built in 1851 by Sir Titus Salt to house workers at his textile mills) and Akroydon (developed from 1859 by Colonel Edward Akroyd to service his mills).
18. The Thursday brothers took their surname from G.K. Chesterton's 1908 thriller The Man Who Was Thursday: A Nightmare.
19. Mark Gatiss stated that he wanted to write "a properly northern Who"
20. Because the episode was underrunning, two new sequences were created featuring Vastra, Jenny and Strax. These were the scenes of the Paternoster gang plotting in the carriage en route to Yorkshire and studying Mrs Gillyflower's poster.
21. Diana Rigg's character is called Mrs. Gillyflower, this may be based on actress Gilly Flower who played the slightly dotty Miss Tibbs in Fawlty Towers.
22. First collaboration between Matt Smith and Diana Rigg, to be followed by Last Night In Soho (2021).
23. The episode was originally called Mother's Ruin.
24. This episode takes place in 1893 and 2013.
25. Mark Gatiss named "Mr Sweet" after his friend film historian Matthew Sweet.Matthew Sweet.
26. The first material to be shot was street scenes.
27. When the Doctor and Jenny are about to be attacked by Mrs Gillyflower's pilgrims ('attack of the supermodels,' as the Doctor dubs them), Jenny reveals she's in a leather catsuit. In The Avengers (1961) - as Mrs. Peel - 'Diana Rigg' was famous for wearing the form-fitting outfits, in both leather (as Jenny is kitted out), or in PVC.
28. Although Jenny and Vastra both question the Doctor concerning how Clara is alive, he neither explains anything to them, nor is she ever present for these questions. Thus despite having met, Vastra and Jenny do not know that this is a different person and not the same one revived in some manner, and Clara gains no knowledge of her past life from the pair.
29. In Mark Gatiss' original conception, Mrs Gillyflower escaped after the launch of her rocket, leading to a carriage chase through the streets of Sweetville which ended when the villainess was thrown and impaled on a statue dubbed the "Bringer of Light".
30. Script development briefly saw Clara take over much of Jenny's role, including fighting the Pilgrims in a leather catsuit.

Nightmare in Silver

1. When talking through the Doctor the Cyber-planner uses the phrases "fantastic" and "allons-y", catchphrases of the Ninth and Tenth Doctor's respectively
2. Steven Moffat stated that the Cybermen were redesigned because they did so often in the classic series, and yet had been consistent in the new series.
3. The three Cybermen seen at the start were the Cybus Industries models from Pete's World.
4. Neil Gaiman was motivated to provide a "rationalisation" for the Cybermen in current Doctor Who (2005) continuity. The classic series had depicted the Cybermen as alien cyborgs, while the revived series depicted them as human cyborgs from a parallel Earth; Gaiman opined that his Cybermen stemmed from an encounter and amalgamation of these two types of Cybermen following "The Next Doctor".
5. Warwick Davis stated that it was a "thrill" to be in Doctor Who (2005), especially in an episode with the Cybermen written by Neil Gaiman.
6. During filming at Castell Coch, a copy of the readthrough script was found in a taxi in Cardiff. It was marked as being Eve De Leon Allen's copy and had the working title of "The Last Cyberman", which was subsequently changed. The script was found by Hannah Durham, who posted a picture of the script to Facebook with the caption: "found Dr Who script in the back of a taxi. Cheeky spoilers anyone?" It was then posted to Reddit by Dan Rowling with the caption: "Look what a Facebook friend found in a taxi in Cardiff on Monday". Arrangements were then made by Hannah Durham and Dan Rowling to return the script to the BBC
7. Both Neil Gaiman and Matt Smith have expressed their disappointment and frustration with this story. Smith found the double acting role to be a hard role and received little support from the crew, whom Smith constantly voiced his frustrations at. Gaiman meanwhile enjoys the script as he wrote it but found that the finished product was misinterpreted by the director, leaving a lot of his intentions unclear. Gaiman revealed in 2018 that he felt like the product was being taken out of his control and being weakened without his consent, leaving him with a bitter experience. Whilst this hasn't altered his love of the show or his desire to return, it did lead him to demand full creative control over future projects based on his scripts.
8. Neil Gaiman felt that it made sense for the Cybermen to be regularly updated, thinking in terms of how quickly modern technology, like smartphones, was evolving. He also wanted to make the Cybermen more stealthy and spooky, whereas the modern versions had been portrayed as noisy and slow-moving. Gaiman felt that the parallel-universe Cybermen would likely have merged with their counterparts from Mondas, giving him the freedom to conceive a new form of Cyberman which drew upon the best of all of their previous appearances.
9. Steven Moffat wanted this story to 'make the Cybermen scary again'.
10. Neil Gaiman thought it was unlikely that he would ever work on the series again, especially since Doctor Who: The Doctor's Wife (2011) had proven to be a time-consuming endeavour.
11. Neil Gaiman was inspired by the story of the Turk, allegedly a man-shaped, chess-playing automaton constructed by Wolfgang von Kempelen in 1770 and eventually destroyed by fire in 1854. The Turk was in fact an elaborate hoax: the cabinet at which the lifelike figure sat was carefully designed to hide an operator, even though the space could be opened to reveal that it seemingly contained only the Turk's mechanisms.
12. The episode was to end with an ominous scene in the Cyberiad featuring Cybermen from throughout their televised history, including the "Oldest Cyberman" (resembling those seen in "The Tenth Planet") who would hint at a broader plot to snare the Doctor. This element would eventually be dropped, while Neil Gaiman also struggled to find a way to better involve the Doctor in the action. He finally came up with the idea of engaging the Doctor and the Cyber-Planner in a duel set inside the Time Lord's mind, affording Matt Smith the opportunity to give a very different onscreen performance.
13. The command insignia first worn by the Captain and then by Clara is actually the cap insignia for an Air Force General of the German Federal Armed Forces (Bundeswehr).
14. According to "Behind the scenes...", the Cybermen were redesigned for this episode and got a variety of new abilities and features. These new Cybermen share several similarities with the Borg Collective of Star Trek - which were in turn originally based somewhat upon the Cybermen. The Cybermen's ability to adapt to attacks is reminiscent of the Borg from Star Trek: The Next Generation (1987). Additionally, the Borg used nanoprobes to convert individuals, similar to the cybermites, and Webley's cyber-appearance is reminiscent of the Borg's "half machine, half human" face. And as of Star Trek: First Contact (1996) they, like these Cybermen, assimilated new members by use of tubules coming out of their wrists/back of their hand. Voice notifications for individuals to convert were also typical for the Borg and the Cybermen, both new and old.
15. Neil Gaiman also wanted to adapt two related ideas which had been introduced during the Sixties. Although never named on screen, the Cyberman Planner had debuted in "The Wheel In Space", and was an immobile entity which directed the Cybermen's activities. Now it gave rise to the Cyber-Planner, who could serve as a more personal adversary for the Doctor than the faceless, emotionless Cybermen themselves. The Cybermats, first seen in The Tomb Of The Cybermen and most recently in Closing Time, were used by the Cybermen for infiltration. Gaiman knew that the Cybermats had been inspired by silverfish, and this led him to take the concept to its next logical stage, in the form of the Cybermites.
16. Neil Gaiman's progress was stalled by the loss of his laptop, as well as the distraction of other commitments.
17. On redesigning the Cybermen, Gaiman thought back to classic series serials "The Moonbase" and "The Tomb of the Cybermen" and decided to "take the 1960s Cybermen and [incorporate] everything that's happened since". However, Gaiman said that he "got completely side-tracked by a mad, strange romp".
18. Neil Gaiman wanted to set the story on a beach, where the Cybermen would rise out of the ocean, but budget constraints prevented that.
19. The bomb used to blow up the planet look like an old fashioned stereo "Boom" box right down to the carrying handle.
20. For a couple of drafts, after the defeat of the Cybermen, Angie saw an older version of herself - wearing a wedding dress - who had apparently been brought to the imperial ship by a future Doctor.
21. The Doctor refers to Cybermen being vulnerable to cleaning fluid and gold. The gold weakness was introduced in Doctor Who: Revenge of the Cybermen: Part One (1975) and reappeared in every subsequent story of the classic show. The lesser known cleaning fluid weakness is a reference to Doctor Who: The Moonbase: Episode 1 (1967) in which a cocktail of different chemicals was used to melt Cybermen chest plates.
22. Hedgewick's World was originally called Lampwick's World, until it was found to be the same as that of a store which sold light fixtures.
23. The showdown with the Cyber army was originally set on an island attraction accessible only by boat; like the castle which replaced it, this bore the moniker "Natty Longshoe", which was an homage to the title character of the 1945 children's novel Pippi Långstrump (that is, Pippi Longstocking). Nehemiah Webley, meanwhile, was named after folk and alternative musician Jason Webley, who had collaborated with Neil Gaiman's wife, Amanda Palmer
24. Broadcast 30 years after Warwick Davis first achieved fame in his acting debut as Wicket in Star Wars: Episode VI - Return of the Jedi (1983)
25. When the Doctor lets the Cyber-Doctor access his memories on regeneration, the First, Second, Third, Fourth, Fifth, Sixth, Seventh, Eighth, Ninth and Tenth Doctor are seen. Each image of an incarnation is taken from photograph stills used as promotional material during the respective actors' tenures. All of these images can be found on the banner of the Doctor Who BBC America website, and the same images are used in the end credits of The Day of the Doctor (2013).
26. Near the end Angie says "when someone asks you if you want to rule the universe, you say 'yes'!" This is a nod to the line "Ray! When someone asks if you're a god, you say 'yes'!" from Ghostbusters (1984)

The Name of the Doctor

1. This is the first episode to use colourised footage of black and white material originally filmed in the 1960s.
2. Matt Smith and Jenna Coleman were told not to swing on the bars during the TARDIS's fall to Trenzalore. He went and did so, anyway.
3. This story features for the first time on television the Doctor prior to stealing the TARDIS.
4. This is chronologically the last event in River Song's personal history, taking place after her death in the Library. It's implied she fades from existence at this point. However, Alex Kingston would reprise the role one last time in Doctor Who: The Husbands of River Song (2015), which was intended to be her final appearance in the series.
5. The War Doctor came about because Christopher Eccleston declined to appear in Doctor Who: The Day of the Doctor (2013). Steven Moffat briefly considered positioning the Eighth Doctor as the Doctor who had ended the Time War, but felt that this was inconsistent with Doctor Who (1996).
6. Achieved overnight ratings of 5.46 million viewers on BBC One.
7. Clara appearing throughout the Doctor's timeline involved a combination of recording on sets with stand-ins representing various incarnations of the Doctor as well as his granddaughter Susan, plus greenscreen work to insert Jenna Coleman into archival footage.
8. Ultimately, Clara's companionship with the Doctor is something of an ontological paradox; the Doctor might not have invited 21st Century Clara to travel with him if he had not met the echoes of her in the Dalek Asylum and Victorian London, but if she never travelled with the Doctor, those echoes would never have existed.
9. Lead writer Steven Moffat stated that he had wanted to have a new monster in the finale, after the series had seen the reappearance of old monsters such as the Ice Warriors, Cybermen and Daleks. The idea of The Whisper Men came from "the thought of stylish, whispering, almost faceless creatures" which seemed frightening and appropriate for "an episode that looks forward and back".
10. The shot of Oswin looking out on a futuristic city was simplified from a longer version in which Oswin tells her mother that she feels compelled to go out into space for a reason she can't explain.
11. The episode boasted a cornucopia of video and sound clips from throughout the programme's long history. Most notably, in the sequence where the Gallifreyan version of Clara prompts the First Doctor to steal the TARDIS, William Hartnell appeared courtesy of two colourised shots from the Doctor Who: The Warriors of Death (1964) and Doctor Who: The Day of Darkness (1964), together with dialogue from Doctor Who: Invasion (1965). Clara and/or Dr Simeon were also inserted into clips featuring the Second Doctor (from "The Mind Robber" and Doctor Who: The Five Doctors (1983)), the Third Doctor (also from Doctor Who: The Five Doctors (1983)), the Fourth Doctor (from "The Invasion Of Time"), the Fifth Doctor (from "Arc Of Infinity"), and the Seventh Doctor (from "Dragonfire"), with a Yeti appearing from "The Web Of Fear". Emanating from the rift were the sounds of the First Doctor (from "100,000 BC"), the Second Doctor (from "The Moonbase"), the Third Doctor (from "The Time Monster"), the Fourth Doctor (from "Genesis Of The Daleks"), the Fifth Doctor (from "The Caves Of Androzani"), the Sixth Doctor (from "The Trial Of A Time Lord"), the Ninth Doctor (from Doctor Who: The Parting of the Ways (2005)), the Tenth Doctor (from Doctor Who: Voyage of the Damned (2007)), and the Eleventh Doctor (from Doctor Who: The Pandorica Opens (2010)).
12. This is the first season finale in the revived series to be set primarily on another planet.
13. This episode takes place in 1893 and 2013.
14. In Steven Moffat's original conception, the Doctor would explicitly identify the time rift in his tomb on Trenzalore as leading back to the final day of the Time War. Once Clara had been splintered and scattered throughout the Doctor's life, he didn't enter the rift to save her. Instead, Clara emerged from it on her own, but then started screaming about knowing who the Doctor really is. This convinced the Doctor to return to the Time War via the rift, leading into the anniversary special.
15. When the Doctor and Clara are in the TARDIS hovering over Trenzalore he says he never thought he would die like this, he thought he would maybe "retire, take up water colours or beekeeping or something." 'Beekeeping' is a reference to Sherlock Holmes, of which Steven Moffat is a huge fan. In the books Sherlock retires to Sussex Downs in his later years and takes up beekeeping.
16. While trapped in the Doctor's time stream, the First, Sixth, Ninth, Fifth, and Fourth Doctors move past, behind, and in front of Clara. Unknown actors portrayed them. The actor portraying the First Doctor resembles the appearance of Richard Hurndall, who replaced William Hartnell in "The Five Doctors".
17. This is the second series finale of the revived series not to feature a Dalek (Doctor Who: Last of the Time Lords (2007) being the first), though the Dalek Asylum is mentioned and appears in a flashback.
18. The Sycorax in the Christmas invasion (2005) are briefly mentioned by the great intelligence.
19. The Doctor refers to the time traces as "the tracks of my tears", to which Simeon replies "enough of the poetry". Tracks Of My Tears is a song by Smokey Robinson, who is often referred to (after a quote by Stewart Maconie) as "America's greatest living poet".
20. At the graveyard, the Doctor and Clara exit the TARDIS [17m05s]. In the foreground there is a grave bearing the name 'Clemency Bunn'. Clemency Bunn was one of the set painters. (See Art Department credits).
21. While the Doctor is dying and his whole time line rewritten, there is a shot of the night sky over Trenzalore with star after star going out, worlds he once saved in his original time line but not in the r rewritten one. That is actually not in conflict with general relativity for once, as long as the destruction of these worlds occurred so long ago that the light they had been emitting since then already had reached Trenzalore.
22. The scene between the Doctor and River, where they say their final goodbyes before River fades away, was filmed in just one take, and by the end both cast and crew were in tears.
23. The episode was leaked early after a bbc america store acidently sent out the season 7 box set two weeks before the episode aired. Despite steven moffat asking for people to not reveal anything one newspaper revealed spoilers from the episode, including the reveal of john hurt as a new doctor
24. Costume designer Howard Burden later confirmed that John Hurt's character is a "dark Doctor" existing between the Doctor's Eighth and Ninth incarnations.
