Doctor Who

Season 6

The Impossible Astronaut

1. This episode is dedicated to Elisabeth Sladen (renowned Doctor Who companion Sarah Jane Smith), who died a few days before its original airing. The episode's broadcast on BBC One was immediately followed by the airing of My Sarah Jane: A Tribute to Elisabeth Sladen (2011) on CBBC (the home network of The Sarah Jane Adventures (2007)).
2. Originally Mark Sheppard was to wear old age makeup in order to play the 2011 version of his 1969 character. Instead, at Mark's suggestion, William Morgan Sheppard (Mark's father) was cast for the part. The pair had also played two versions of the same character about a year earlier in an episode of NCIS (2003).
3. When on the TARDIS, the Doctor remarks on how Sundays are boring. The Tenth Doctor said the exact same thing to Donna in season four Doctor Who: Silence in the Library (2008).
4. Alex Kingston had to genuinely slap Matt Smith several times in a scene because it was difficult to fake. Kingston recalled that after a few takes, Smith got red cheeked and grew frustrated at having to do the sequence over and over again.
5. A scene that was cut because it was deemed too naughty, which River Song is naked, can be glimpsed in the Series 6 trailer, but it didn't make the deleted scenes on the Series 6 DVD box set.
6. Even though Mark Sheppard is an English actor, this was his first appearance in a British-made television show. And, he plays an American character, unlike his appearances on American television, where he usually uses his natural British accent.
7. When the Doctor is calculating where and when to go to find Canton Delaware III, he states that Sundays, Tuesdays, and Thursday afternoons are boring times for the TARDIS to go. It then directs him to April 8, 1969, which was in fact a Tuesday.
8. Stuart Milligan found the role of Richard Nixon exciting, having played other presidents in the past, including Dwight D. Eisenhower. Prosthetic pieces were applied on Milligan's cheeks, nose, and ears to make him resemble Nixon as much as possible. He also practiced how Nixon would speak, but initially found it difficult since he had to wear fake teeth.
9. The Silence were inspired by the impermanence and unreliability of memory. Visually, they were inspired by Edward Munch's painting 'The Scream'.
10. In filming the "Viking funeral" scene, Toby Haynes wanted to film it during the sunset. However, the sun set over the desert, so was instead filmed during sunrise, as the sun rose over the water.
11. Mark Sheppard described playing Canton as a "dream job," and said he wished to appear in another of Steven Moffat's works, including Sherlock (2010).
12. The location listed on Amy and Rory's invitation is 37º0'38" N, 110º14'34", which is atop Oljato Mesa in southeastern Utah, USA., about 0.85 miles (1.37 km) north of the Utah-Arizona border. There is no Lake Silencio, nor any other body of water large enough to be a lake nearby; the closest body of water is Lake Powell (a reservoir created by the dammed Colorado River) about 35 miles to the northwest.
13. The Oval Office set was constructed at Upper Boat Studios in South Wales. Because the production crew had access to several pictures and plans of the real office, they were able to replicate it in almost every detail. The main problem for building the set was the plastering; the crew normally plaster one wall at a time for normal rooms, but because the Oval Office was round, they had to do the entire set at once.
14. Florida (to tie into the NASA element) and Mount Rushmore in South Dakota were also considered as potential locations.
15. In the script, Amy and Rory were dropped off by a truck. Toby Haynes altered this to a yellow school bus as he felt it was more distinctly American.
16. A scene had been written and filmed by got cut because Steven Moffat felt it was too naughty, which a naked River Song winks at an unknown man. The deleted scene could be glimpsed in the Series 6 trailer.
17. This episode takes place on April 22, 2011 and April 8, 1969.
18. The Laurel and Hardy film The Flying Deuces (1939), in which the Doctor intruded, was done by Matt Smith dancing in front of greenscreen. This is a reference to a skit from the 1992 Academy Awards in which Billy Crystal was depicted alongside Laurel and Hardy.
19. The working title for this episode was The Year of the Moon.
20. The Doctor carries his own soda straw with him, much like the plasmavore in Doctor Who: Smith and Jones (2007).
21. River remarks to Rory that, because of their unsynchronized time traveling, there will come a time when she meets the Doctor and he will have no idea who she is, and she thinks its "going to kill" her. In fact, the first time that the Doctor met River was the episode in which she died, back in season four's Doctor Who: Silence in the Library (2008).
22. While recording the Doctor's apparent demise, Alex Kingston drew on her knowledge of the season's secrets and decided that River would react in a particularly comforting way towards Amy. Karen Gillan, however, was unaware that their characters would soon be revealed as mother and daughter, and was quietly baffled by Kingston's demeanour.
23. Karen Gillan was genuinely upset while filming The Doctor's 'death' scene.
24. In this episode, the Doctor 'dies'. It was broadcast 23 April 2011. 36 years earlier, 23 April 1975, was the day that William Hartnell, the first actor to portray the Doctor, died.
25. When Rory sees The Doctor alive, he pokes him, similar to The Doctor poking Rory when he saw that he was alive in Doctor Who: The Pandorica Opens (2010)
26. Alex Kingston and Sydney Wade had come off of filming Marchlands (2011) in which they played a mother & daughter, immediately prior to filming this episode in which they portrayed older & younger versions of Melody Pond/River Song.
27. The diner that the Doctor brings his companions to is later revealed to be Clara and Me's stolen TARDIS, or at least the inspiration for it. This implies that they visited the Doctor along his timeline at least once, especially since Clara was the Eleventh Doctor's companion first and likely wanted to check up on him once she gained the ability to travel through time herself.
28. The Diner that the characters go to is located near the millennium centre in Cardiff, which is where many of the scenes in "The Girl Who Waited" were filmed. It is also near the Ianto Memorial(Torchwood) which is outside the MC.
29. The Doctor appears to begin to regenerate before he is struck down, which becomes slightly puzzling given the fact that it is later revealed that at this point he had already used up all of his regenerations and was on his last body. This continuity error is due to the fact that the War Doctor had not yet been introduced, nor had it been established that the Tenth Doctor's aborted regeneration added to the number that had been used up. Given that the scene was actually staged by the Doctor himself, it's also possible that he wanted to be more convincing by eliminating any speculation about a delayed regeneration.
30. Madame Kovarian (Frances Barber), the main antagonist of Series 6, was influenced by Emilio Largo, the main villain of Thunderball (1965). Largo is the one-eyed member of the Spectre criminal organization. Madame Kovarian whom is one-eyed and was credited as "Eye Patch Lady" works for The Silence, which is a sinister relics order.

Day of the Moon

1. The Silence masks caused vision difficulties for the performers, who had to be guided by two people when they had to walk.
2. Delaware was written to be deceptively antagonistic towards the protagonists, which was based on Mark Sheppard's past as villains for his work in American television.
3. The Doctor tells Nixon that he has to tape everything that he says in his office or else he won't know if the Silence has affected him. This is a reference to the Nixon tapes, with the famous eighteen and a half minute gap in one of the tapes.
4. Incorporating Richard Nixon into the plot was accidental. Steven Moffat wanted to set the story during the moon landing and looked up the United States president during the time. He was initially disappointed that it was such a "rubbish one" and briefly considered using a generic, unnamed president, such as the one seen in "The Sound of Drums". However, he thought it "didn't feel right for a story partly about real events" and realized it could be fun to use Nixon. He believed there was something "comically awkward" about him, and it would be interesting for the Doctor to have to work with someone he did not like.
5. There were originally two running gags - the Doctor insisting on keeping his beard, and River refusing to remove his handcuffs. These eventually dovetailed when River advanced upon the restrained Doctor with a shaving razor in hand.
6. The control room set used from "The Lodger" was used again for this episode. Steven Moffat wanted the set to be used again, feeling it would be a suitable Silence base. The set was adapted to give it a darker, evil feel. Because of this, fans have been theorising that the ship from "The Lodger" is the same ship here.
7. This episode had the working title Look Behind You.
8. Matt Smith wore a glued-on beard, which was difficult to peel off.
9. This episode takes place in July 1969 and 1970.
10. At around 17:20, Rory salutes two men and says "America salutes you", but his palm is facing forward. This is a British style of salute.
11. The Doctor claims that the blue envelope was the first time he was summoned by a stranger who wouldn't even show his face, yet he was summoned in just this way when River sent him a message on the psychic paper the first time they met (from his perspective).
12. A scene was filmed, but deleted because Steven Moffat deemed it too naughty which a naked River Song winks at The Doctor at the Stormcage Containment Facility. The deleted scene can be glimpsed in the Series 6 trailer.
13. The Doctor mentions David Frost, referencing the famous interviews of President Richard Nixon by Frost, which were dramatized in the stage play and subsequent film Frost/Nixon (2008). Michael Sheen, who played Frost in the film version, appears as the voice of House two episodes later in "The Doctor's Wife".
14. The scene in which Amy confronts Canton was originally watched by three Silence in the script.
15. Dr Renfrew was named after RM Renfield from "Dracula".
16. Doctor Renfrew is named after the town next to Paisley, the town Steven Moffat is from. Paisley is in the county of Renfrewshire.
17. Arthur Darvill would be depicted infiltrating a moon launch in his later role of Rip Hunter on "Legends of Tomorrow".
18. The sequence where Delaware chases Amy was shot in the Valley of the Gods in Utah. Karen Gillan found it difficult to run because of the altitude.
19. The "young girl" was originally going to regenerate in Chicago.
20. Rory's capture by Canton was conceived as taking place at docklands near the Golden Gate Bridge in San Francisco.
21. The doctor opened the doors of the TARDIS by snapping his fingers at the beginning of this episode. This has only happened twice before (silence in the library/forest of the dead/The Eleventh Hour).

The Curse of the Black Spot

1. This episode was supposed to air in the autumn half of the series, but was swapped around, along with "The Doctor's Wife" being fourth instead of third and "Night Terrors" being ninth instead of fourth. This was because Steven Moffat felt "Night Terrors" was too dark.
2. The exterior of the pirate ship was filmed at a dock in Cornwall, while the lower decks were built from a set at the studio. The principal challenge to film at the dock was to ensure the audience would not see it. The crew set up smoke machines to simulate fog. To create the storm the crew used wind and rain machines, the latter of which went through 15,000 litres of water.
3. This episode takes place in 1699.
4. The working title for this episode was The Siren.
5. Pirates and "the black spot" as an indication of judgment and doom is a literary device invented by Robert Louis Stevenson. In the 1883 novel "Treasure Island" Billy Bones and Long John Silver both receive a black spot.
6. A significant continuity error was introduced in editing, when the removal of scenes involving the Boatswain - in which he was manacled to the ship's bulkhead and then cut himself trying to escape, resulting in his capture by the Siren - meant that the character abruptly vanished from the narrative, only to reappear as a patient on the spaceship at the end of the story.
7. The episode was also made to allow the Doctor and his companions to "kick back and have some fun."
8. Anticipating they would get soaked, the cast present on the deck wore dry suits underneath their clothes.
9. The 4th pirate story which The Doctor has encountered pirates. In the 1966 William Hartnell story The Smugglers, The 1st Doctor, Ben and Polly encountered pirates led by Captain Pirates on the Cornish coast in the 17th century. In the 1969 Patrick Troughton The Space Pirates, The 2nd Doctor, Jamie and Victoria encountered space pirates led by Caven aboard a stolen space beacon and in the 1978 Tom Baker story The Pirate Planet, The 4th Doctor, Romana and K9 encountered the space pirate The Captain on the pirate planet Zanak.
10. The sickbay set was built in a studio. Because the beds were attached to strings, they were prone to swaying.
11. Lee Ross (the Boatswain) starred in The Press Gang which was written by Doctor Who showrunner Steven Moffat.
12. Broadcast 45 years after the William Hartnell story The Smugglers. In that story, The 1st Doctor, Ben and Polly encountered 17th century pirates.
13. The cast members who were asked to lie on the beds were instructed to stay still and not breathe heavily to limit movement.
14. The Curse of the Black Spot is a nod to the Disney pirate film Pirates of the Caribbean: Curse of the Black Pearl (2003).
15. In 2019, Karen Gillan was rumored to replace Johnny Depp in a reboot of the Disney pirate franchise Pirates of the Caribbean: The Curse of the Black Pearl (2003).
16. Karen Gillan was allowed to perform several of her own stunts in the episode. She was excited to learn that her character would fight pirates with swords, and was taught how to handle one with basic moves. Gillan was also allowed to swing across the ship. However, a stunt double was required to film the sequence where Amy is thrown across the deck by the Siren.
17. This episode is notable both in that none of the guest cast die and there is no villain of the piece.
18. One late deletion from the script was the idea that the Siren would appear to Toby Avery as a young girl. This would have given the Doctor a clue as to the entity's true nature.
19. Steve Thompson was inspired by a popular Cornish legend about "the Mermaid of Zennor", which apparently dated from the fifteenth century. The story concerned a mermaid with a beautiful singing voice who tempted a human man to come live with her in the sea. It is associated with an ancient chair bearing a carving of a mermaid, which can still be found at St Senara's Church in Zennor.
20. The scenes in which Lily Cole appeared on the ship were done by using a harness as if she was flying. Because the actress wore green dress and makeup, the normal greenscreen was replaced by bluescreens in the studio. Cole felt it was fun to fly on the harness, but found it painful after a few hours.
21. Henry Avery was a real pirate and was mentioned in the classic series episode "The Smugglers". Steve Thompson was unaware of this. He'd simply looked through his sons' book about pirates and picked Avery because of his mysterious disappearance.
22. Amy fights with a sword. An older version of Amy would fight with a Samurai sword in Doctor Who: The Girl Who Waited (2011).
23. Before filming began on the storm sequences, Arthur Darvill heard that he would perform the stunt where he is thrown into the sea, and was willing to perform it. The stunt would later be performed by a double.

The Doctor's Wife

1. When Amy and Rory are running through the halls of the TARDIS it is only the second time, since the return of the show in 2005, that any part of the TARDIS other than the control room has been shown.
2. The junkyard, where "The Doctor's Wife" takes place, was written as a nod to the first ever episode "An Unearthly Child". Which Ian and Barbara met The 1st Doctor and Susan at a junkyard in contemporary London and discover The TARDIS.
3. A scene featuring the TARDIS swimming pool was removed because Karen Gillan couldn't swim.
4. Neil Gaiman based House's personality and his treatment of Rory and Amy on AM in Harlan Ellison's famous short story "I Have No Mouth and I Must Scream". Gaiman posted on Tumblr that he hoped to make Harlan Ellison smile with the shout-out. Apparently, he did.
5. At a certain point, Neil Gaiman became tired of re-writing drafts and asked Steven Moffat for help. Moffat wrote in what Gaiman called "several of [the episode's] best lines" and rapidly rewrote several scenes when budget problems harmed filming locations.
6. While it has been hinted at before a few times in the series, most directly in "The End of Time", this episode offers the first concrete confirmation that Time Lords can change genders when they regenerate. This was a deliberate addition to the mythos on Neil Gaiman's part.
7. Arthur Darvill noted the floor of the older TARDIS set had a cheese grater-like quality to it, so when the scene called for the cast to fall on it, they found it uncomfortable to stay down for a long period of time.
8. Neil Gaiman originally created a new alien for Nephew, but was asked to choose a previously established race (an Ood) when the budget didn't allow for the creation of a new monster.
9. During a read-through of the script, the producers asked Suranne Jones to "neutralise [her accent] a bit," because they did not want Jones to "be a Northerner" or have a standard accent, but to act "kinda like the Doctor."
10. Neil Gaiman chose the name Idris because it was an unusual but authentic name which resembled "TARDIS".
11. Uncle, Auntie and Nephew were conceived as monstrous amalgams of various alien races, but the budget could not cover the extensive prosthetics necessary. As such, the physical changes to Uncle and Auntie were rewritten to be more subtle.
12. Originally, House would be revealed as having grown from a spore which entered a bubble universe via one of the cracks in time which featured throughout Series 5. Neil Gaiman intended the Doctor to glimpse the true House, an enormous mollusc-like entity concealed beneath the asteroid's mantle.
13. The TARDIS corridors built for this story are now standing sets, available for use in future stories.
14. The Eleventh Doctor Companion mentions additional script elements that were cut before broadcast, including the fact the TARDIS indicates that the chameleon circuit is not broken - she simply stays as a police box because the Doctor likes it; and, during their farewell conversation, the TARDIS was to tell the Doctor he was forgiven for his actions in the Time War (providing narrative bookending to the earlier discussion about the Doctor wanting to be forgiven).
15. The Junk TARDIS console was the subject of a 2009 design competition on Blue Peter (1958).
16. The main villain of the story was originally The Great Intelligence.
17. When Amy was sent back to the TARDIS to fetch the sonic screwdriver, she originally found her engagement ring - a version of which ultimately appeared in "The Lodger".
18. Suranne Jones (Idris) has previously appeared in the Doctor Who universe as the Mona Lisa in The Sarah Jane Adventures (2007) in The Mona Lisa's Revenge.
19. The episode originally opened with the Doctor, Amy and Rory about to be sacrificed to rain gods on a primitive planet, before the arrival of the Corsair's psychic container scares the locals and affords the time travellers a chance to escape back to the TARDIS. Due to time and budget constraints, it was changed to the trio in the TARDIS.
20. "The Doctor's Wife" was also a fake title attached to the 1984 serial The Caves of Androzani. Then-producer John Nathan-Turner had changed the title to that on his planning board in an attempt to weed out a suspected leak in his office.
21. Working titles for this episode included The TARDIS Trap, Bigger on the Inside and The House of Nothing.
22. A scene involving House toying with Amy and Rory's perceptions as they traverse a hallway lined with mirror-like walls was cut due to budget constraints. The concept was allegedly inspired by Poltergeist III.
23. This episode was originally planned as the eleventh episode of Series 5, but because of budget limitations was delayed until Series 6.
24. A scene where Rory is trapped in the TARDIS Zero Room from Castrovalva was cut due to budget constraints.
25. House is voiced by Michael Sheen, who previously played David Frost in Frost/Nixon (2008). Two episodes earlier, in Doctor Who: Day of the Moon (2011), The Doctor told President Richard Nixon to "Say hi to David Frost for me".
26. On his blog, Neil Gaiman released a short conversation between Amy and the Doctor that did not make the final cut in the episode he wrote.
27. Idris refers to Arthur Darvill's character Rory Williams as "the pretty one", indicating some level of fondness or attraction. Later in Darvill's career, the soul of another time ship, Gideon, would kiss him in an obvious homage to this episode.
28. The original plan focused on the idea of the Doctor being pursued by an enemy inside the TARDIS.
29. The Doctor and The TARDIS state that the Doctor has only been traveling for 700 years. As he was known to be at least 900 years at the point in time of this episode, that would mean The Doctor was in his 200's when he stole the TARDIS.
30. Neil Gaiman wrote Good Omens starring David Tennant and Michael Sheen
31. When Amy and Rory are running through the TARDIS and Amy and Rory get cut off for the second time, it doesn't show Amy turning around to the door that closes on Rory
32. The console room set used by the Ninth and Tenth Doctors was left standing for eighteen months after its last appearance, so that it could be used for this episode.
33. Before mentioning fish fingers and a motorbike, Idris, as the TARDIS, says an unintelligible line. That line was English backwards which, spoken forward, is "The only water in the forest is the river".
34. When Idris (as the TARDIS) is locked in her cell, she says several lines of dialogue that don't make sense, then wonders why she's saying them. Later in the episode, those lines turn up in dialogue in-context.
35. When Idris is dying she says to Rory "The only water in the forest is the river", which is brought up a few episodes later as the explanation for River's name.
36. In the TARDIS graveyard, one draft depicted Idris deactivating the chameleon circuits of all the other time machines, resulting in the sight of dozens of everyday objects suddenly metamorphosing into their default TARDIS state.
37. This is the second televised story in which every character, except for the Doctor and his companions, dies (the first was Horror of Fang Rock, featuring the 4th Doctor).
38. Early drafts of the script featured more of Idris before having her soul removed, more backstory about the Corsair's relationship with the Doctor, more TARDIS rooms, burial of Idris' corpse and clear indication that House survived its defeat.
39. When The Doctor dances with Idris, Murray Gold's soundtrack resembles a tune from Les Miserable called "Waltz of Treachery" (on the Who soundtrack, it is within the song titled "My Tardis"). This could be a reference to House's treachery, but it is more likely that Gold is referencing the miserable loneliness and loss that the Doctor and his TARDIS share as they travel the universe.
40. The makeshift console created by the Doctor and Idris was inspired by the Third Doctor's travel via console to a parallel universe in Inferno.
41. The old control room that Idris/TARDIS sends Rory and Amy to appears to be the control room of the TARDIS used in Series 1-4 before it was redesigned for Series 5.
42. Rory originally didn't appear in the script, as the episode was originally meant to take place during Series 5 when Rory was not aboard the TARDIS with Amy and The Doctor; at that point he would have still been dead and erased from existence.

The Rebel Flesh

1. Steven Moffat suggested that the avatars work in a factory. Attempting to make it different from other factories featured in the series, Matthew Graham proposed to set the story in a monastery, an idea of which Moffat greatly approved.
2. Steven Moffat indicated that the Doctor should be proactively investigating the Flesh, rather than happening upon the St John's monastery by chance.
3. Matthew Graham wanted the Gangers to be scary, but not monsters who wanted "to take over the world for the sake of it". He wanted them to appear relatable to the audience as they were humans who deserved rights.
4. Originally, the facility would have housed a much larger complement of both staff and Gangers, but these numbers were cut back both for budgetary reasons and to accentuate the atmosphere of claustrophobia and paranoia.
5. In the early drafts of the script, there were "so many copies of people running around the place" which made the story too confusing, so Matthew Graham and the production crew worked to make it more rational.
6. The monastery was inspired by The Name of the Rose (1986), while the Gangers were influenced by The Thing (1982).
7. Steven Moffat devised a story about "avatars that rebel". Initially worried this may seem too similar to Avatar (2009), Matthew Graham went on to create the Flesh.
8. The cold temperatures at the time were a challenge and caused discomfort. The crew were concerned that the cast, particularly the three lead actors, would fall ill as their costumes were not designed for such weather conditions. Even so, the cast remained healthy.
9. Matthew Graham, who wrote this episode, is the co-creator of the series Life on Mars (2006) and its sequel series, Ashes to Ashes (2008). Marshall Lancaster, who appears in this two-parter, plays the character of Chris Skelton on both of these shows.
10. Raquel Cassidy was cast three days before filming after the originally cast actress pulled out.
11. The arrival of the TARDIS at St John's was originally more involved, and included the Doctor revealing the existence of a "dear little hatch" in the bottom of the police box.
12. A "chief computer" was to feature in the dining room, which chatted with the humans in a Yorkshire accent.
13. This episode takes place in the 22nd Century.
14. Raquel Cassidy and Matt Smith had previously starred side-by-side in the political drama Party Animals (2007).
15. Sarah Smart had no idea which of the Two Jennifers she was playing at times.
16. The episode also contains a subplot in which Rory helps and protects Jennifer as she is scared and affected by the Gangers, which proved a twist in Amy and Rory's relationship. Karen Gillan enjoyed the twist. Amy had previously always had Rory "in the palm of her hand" and a different side of the character was shown as she experienced the same emotions Rory felt when she seemed interested in the Doctor. Arthur Darvill also thought it gave Rory a chance to "man up" and be a hero by protecting someone.
17. Steven Moffat wanted the Gangers to appear like "eyeball matter": white with small capillaries running through them.
18. Jennifer originally had perfect recall, which explains why her Ganger is able to overcome the memory suppression protocols.
19. The actors each played their respective Gangers, with prosthetics applied to their faces for when the duplicates' faces reverted to the original material of the Flesh.
20. For the scenes in which both the character and their respective Ganger was in the same shot, a double for each of the actors was used. Most of the shots showed either the character or their Ganger speaking over their counterpart's shoulder, as only the backs of the doubles' head were made to look similar to the actors.

The Almost People

1. Matthew Graham found writing for two Doctors easy, as The Eleventh Doctor had a constant "internal dialogue" and was always finishing his own sentences.
2. The doppelganger Doctor says 'I've reversed the polarity of the neutron flow', this was a favorite saying of the third Doctor and often his solution for many problems.
3. The original script explained that Jennifer has a perfect memory, and so her Ganger was able to remember every terrible thing that had happened to the Flesh.
4. The original ending had Amy having a vision of the "Eye Patch Lady" while the Doctor and Rory head back to the TARDIS.
5. This was the first time Matt Smith had worn prosthetic make-up.
6. The episode's working title was Gangers.
7. It was originally planned that Jennifer would eat Buzzer, but The Mill decided only the shadows of the action would be shown on the wall. All of this was cut from the final episode, with the exception of Jennifer's elongated mouth as she advanced towards him.
8. This episode takes place in the 22nd Century.
9. At one point in this episode, the Doctor says he is 'John Smith'. David Tennant used the name 'John Smith' in Doctor Who: Human Nature (2007).
10. The doctor remarks to his double that he once tried to plug his brain into the core of a planet to win a bet, this is a reference to 'The Forrest of the Dead' where the tenth doctor was going to use his brain as part of the planets core computer which would have killed him if River Song had not taken his place.
11. Matthew Graham originally intended on setting the story in a different location to "throw everybody", but decided that would be unnecessary.
12. Raquel Cassidy and Matt Smith had previously starred side-by-side in the political drama "Party Animals" in 2007.
13. When the ganger Doctor is transforming you can hear David Tennant's voice say "Hello, I'm the Doctor."
14. As the Doctor is transforming, you can hear Tom Baker's voice as he asks if "he" wants a jelly baby.
15. The monster Jennifer transforms into at the end was created with CGI and a photo of Madonna was used as reference, as in the image "her arms were...really sinewy, white, veiny, and fleshy". Matthew Graham wanted the creature to have a real face and an alien body. He was inspired by a drawing in Alice's Adventures in Wonderland that depicted Alice with a long neck.
16. Karen Gillan discussed the labour scene with her mother, and tried to make it "really horrific".
17. In the original script, the Doctor quizzes the Flesh Doctor about the events of The Mind of Evil and mentions former companions Jo Grant, Sarah Jane Smith, Romana, Rose Tyler, Martha Jones, and Donna Noble.
18. The pile of discarded Jennifer Gangers was originally intended to just be a pile of bodies, but it was decided that would be "too grim". Instead, life-sized dolls were used and computer-generated Flesh was painted on it, giving it a more melted look.
19. The death of the Ganger Doctor was to be accompanied by a montage of "happy memories" including travelling with his granddaughter Susan, defeating Davros with Sarah Jane Smith (as seen in Genesis Of The Daleks), meeting Rose Tyler (in Rose), eating fish fingers and custard with the young Amelia (in The Eleventh Hour) and more.
20. The original script contained a scene where the TARDIS provides the Doctor with another sonic screwdriver after he had given it to the Flesh Doctor, in a similar fashion to "The Eleventh Hour".

A Good Man Goes to War

1. According to Steven Moffat, Captain Jack Harkness was going to be part of The Doctor's Army. However, John Barrowman was filming Season Four of Torchwood (2006) ("Miracle Day") in America.
2. This is the first story to include River where the phrase "Hello Sweetie" isn't heard.
3. When Madame Vastra exits her cab, she says "Thank you Parker, I won't be needing you again tonight", and the cab driver responds with "Yes, milady". This is right out of Thunderbirds (1965), where Lady Penelope would address her chauffeur, Parker.
4. This episode features a unique sound mix on the opening theme music, which features the sound of the TARDIS. No Series 6 episode before or after featured this version of the theme.
5. The chevrons worn by the clerics on their sleeves are almost identical to the modern logo of the United States Air Force.
6. In the previous episodes, Frances Barber was credited as "Eye Patch Lady". This episode revealed her name as Madame Kovarian.
7. Originally the episode contained a scene with Ood Sigma, previously seen in "Planet of the Ood", "The Waters of Mars", and The End of Time, but it was cut from the final episode.
8. First appearance of Madame Vastra, Jenny and Strax.
9. The idea that the word "doctor" derives from the Doctor was first advanced by Steven Moffat in a Usenet post in 1995.
10. Steven Moffat devised many false endings for the episode, one of which - a putative revelation about the Doctor's true name - was even used for the readthrough.
11. The uniforms and insignia worn by the soldiers are of identical design to the Airman Battle Uniform (ABU) worn by members of the United States Air Force.
12. This episode takes place in the 52nd Century, 1888, 4037 and the 51st Century.
13. Alex Kingston filmed her roles in two days.
14. Working titles for this episode included Demons Run and His Darkest Hour.
15. The battle in which Strax was serving as a nurse took place on Zaruthstra in 4037 CE. The human inhabitants of that world are seen to be wearing 19th century British clothing.
16. Alex Kingston and Frances Barber both worked together before in Warrior Queen (2003).
17. When Dominicus and Lucas are talking about Demon's Run being on Yellow Alert, Lucas states that they have been on Yellow Alert for 3 weeks. Doctor Who: A Good Man Goes to War (2011) was broadcast 3 weeks after Doctor Who: The Doctor's Wife (2011).
18. The same year this show aired Christina Chong (Lorna Bucket) had a cameo as a air hostess in Johnny English Reborn (2011). Rowan Atkinson (Johnny English) had played The Doctor in the spoof Comic Relief: Doctor Who - The Curse of Fatal Death (TV Short).
19. This episode solves the fan debate as to whether or not The Doctor was speaking Gallifreyan and it was being translated.
20. Karen Gillan and Arthur Darvill were both nervous about holding the infants playing Melody Pond, but they felt it added to their acting.
21. River Song hints at the fact that she is the child of Amelia Pond and Rory Williams when she tells Rory it's her birthday after he arrives at the prison. This reveal comes shortly after Amy has given birth to Melody Pond who would grow up to become River.
22. The TARDIS console room does not appear in this episode. This is the first time this has occurred since "Planet of the Dead", over two years earlier. It is the first episode of the Eleventh Doctor era to not have a scene set in the TARDIS.
23. The Cybermen in this episode are of Cybus design, but for the first time are with the Cybus Industries logo absent.
24. The title of the episode is actually open to interpretation, as the Doctor asserts here that he is not a "good man", because good men don't need rules and he has "so many". This, coupled with Amy's opening narration, which leads the viewer to believe she is talking about the Doctor, but later reveals she is actually talking about Rory, implies that Rory is the "Good Man" spoken of in the title.
25. River spends her birthday with the Doctor at the 1814 Winter Frost Fair in London, the last such fair ever held. The dredging of the Thames prevented it from freezing over again. The Twelfth Doctor would later visit the same fair with Bill Potts, and later revealed that he had been there "a few times".
26. There has been fan speculation regarding the possibility that Lorna Bucket is Jenny, the Doctor's daughter, regenerated. This misconception has been put to rest by Russell T. Davies, who said Jenny was revived from the energy of life, not through Time-Lord regeneration, so her appearance would not change.
27. The Doctor does not appear until around 19 minutes into the episode.
28. The Headless Monks were played by stuntmen, and so the main-cast actors were free to improvise their choreography when fighting the stuntmen.
29. For the scene in which the hoods of the Headless Monks are pulled back, a shoulder piece was created for actors who were shorter than the ones who portrayed the monks in other scenes.
30. According to Simon Fisher-Becker, in the original version of the script the scene showing the decapitation of Dorium was longer, with much more emphasis placed on him having no head.
31. In the episode Amy's Choice (#5.7) Amy dreams of being pregnant. This foreshadowed Season 6's story arc concluding with Amy giving birth to Melody Pond, later revealed as River Song.
32. The Series 1 & 2 variation of Doctors theme (The Doctor's Theme) plays for six seconds when the Doctor and Vastra are talking about a Time Lord being used as a weapon.
33. When the Doctor first met River Song in The Library, he told her that as a time traveler, he points and laughs at archaeologists. When he first sees the infant Melody Pond, he laughs and points at her. Later, when he leaves in the TARDIS, he points at the grown River Song and laughs.
34. The "Star Wars" films are a strong influence behind the episode. The Headless Monks are a religious order who can fire energy blasts from their hands and channel red energy into their swords.
35. River implies that she sent a memo to her guards asking that they dress as Roman soldiers, offering a subtle hint that Rory Williams, aka "The Last Centurion" is her father.
36. When Amy is talking to baby Melody about her father Rory, she tells Melody that her father is "The last of his kind. He looks young and he's lived for hundreds of years." This is misdirection. The Doctor is a 903 year old Time Lord in the body of a man in his early 30s and he is the Last of the Time Lords. Rory is a human who has lived for more than 2000 years, and is also known as The Last Centurion.
37. Seven Samurai (1954) is an influence behind this episode. The Doctor and Rory recruit Madame Vastra, Jenny, Strax, Dorium Maldavour and River Song to help them rescue Amy. Madame Vastra wields a samurai sword.
38. The climax, in which River Song reveals herself as Melody Pond, had been foreshadowed in River Song's debut story Doctor Who: Silence in the Library (2008) which River met the tenth Doctor and Donna Noble. Both Donna and Amy are natural redheads and it's possible Donna reminded River of Amy.

Let's Kill Hitler

1. There was a delay in shooting the second half of the season to allow the wheat to grow for this episode.
2. This episode introduces a new article of clothing for the Eleventh Doctor that he continues to wear for most of the remainder of Series 6 - a green, double-breasted moleskin coat with six pockets and six gold buttons. Matt Smith explained that he wanted a longer coat because of cold weather.
3. The famously clumsy Matt Smith was afraid of ruining his tuxedo, so he placed the jacket onto a table and into a glass of grape juice.
4. The German Major-General eliminated by the Tesselecta for his war crimes is named Erich Zimmermann. Ironically, one Erich Zimmerman was one of the co-authors on one of the earliest standard works on the attempt on Hitler's life on July 20th, 1944.
5. The cast and crew felt that the costume and make-up artists did a good job with Albert Welling, as he looked so much like Hitler it was a "surreal" experience.
6. Before broadcast, Matt Smith stated that it was "maybe [his] favorite episode to date...it just rockets along".
7. Jenna Coleman was seen for the role of Mels.
8. Arthur Darvill was pleased that his character, Rory, was more of an "action hero" in the episode.
9. Steven Moffat was overseeing six episodes of Doctor Who (2005), making three film-length episodes of Sherlock (2010) and writing The Adventures of Tintin (2011). As a result, he was stretched too thin and overworked. When filming was due to commence on this episode, his only option was to hand the actors his first draft and hope for the best.
10. This episode takes place in 2011, 1938, the 1990s, the 2000s and the 52nd Century.
11. According to the script, Mels' last name is Zucker.
12. Steven Moffat wanted to show Hitler in a comedic light and "take the mickey out of him" instead of making him "an icon of evil". He was inspired by Indiana Jones and the Last Crusade (1989).
13. Arthur Candy was introduced in the short story Continuity Errors. As such, this marks the first televised appearance of a character introduced elsewhere.
14. When the Doctor asks for someone for a voice interface, the first person is Rose Tyler, the first companion of the Doctor, from season 1-2. Then Martha Jones, the second companion of the Doctor, season 3. Then Donna Nobel, the third companion of the Doctor, season 4. Then young version of Amelia Pond, all of the Doctor companions in order from the beginning of the new series.
15. "Let's Kill Hitler" was broadcast 11 weeks after the mid-season finale "A Good Man Goes to War".
16. The paper Amy is holding and reading instructions off of to Rory in the beginning scene in the wheat field sending a message to the Doctor, looks almost like the ancient/Devil language from "Impossible Planet" 2-parter in Series 2.
17. When the Doctor tricks River/Melody with the gun-to-banana switch, this is a nod to Captain Jack Harkness with the Ninth Doctor when he switched Jack's gun with a banana in "The Doctor Dances". Coincidentally, in her first appearance, River was shown to be in possession of the "Squareness gun" used by Jack in the same episode.
18. Although there have been dialogue hints in the past that a Time Lord regeneration can result in drastic physical changes (e.g. gender change), previous on- and off-screen regenerations have always resulted in a person of the same race and gender as their predecessor. This story reveals that Melody Pond (the Caucasian daughter of Amy and Rory) regenerated into Mels (who appears to be of African or Caribbean ancestry), and later into River Song (Caucasian again).
19. Arthur Darvill was not allowed to ride the motorbike.
20. Mels establishes that she had last regenerated in New York, which was shown starting at the end of Doctor Who: Day of the Moon (2011), regressing to a toddler Mels. She regenerates here in 1938 again as Mels into River Song. Time Lords are normally limited to 12 regenerations (13 lives), last stated in Doctor Who (1996), so she gives up at most 10 regenerations to revive The Doctor, assuming she hadn't regenerated any other times earlier.
21. One scene involving the Teselecta (disguised as a German soldier) chasing Amy and Rory on motorcycles through Berlin was cut from filming due to budget issues.
22. The images of all the former companions are taken from publicity shots. The projections of Rose and Donna are publicity images from Series 4. That of Martha is from a publicity image for Series 3.
23. When River Song says "I think I'll lower the age a bit, gradually, just to freak people out". This gives a reason as to why the River Song in season 4 was younger.
24. The leg pose that River strikes for the Doctor and her seductive "Hello, Benjamin" is an homage to the iconic scene with the lead character's older lover (Mrs Robinson) in The Graduate (1967). In River's future but the Doctor's past he inadvertently nicknames her "Mrs Robinson". River is visibly upset by that nickname, since she would remember having done the leg pose for the Doctor. As another level of irony, the plot of The Graduate is about Benjamin Braddock's choice between his older lover (Mrs Robinson) and her daughter (Elaine Robinson), in a way like Amy Pond and her daughter (River) both having feelings for the Doctor.
25. The Anti-Bodies were originally envisaged as humanoid robots with featureless chrome heads.However, it was eventually felt that this appearance hewed too closely to the look of the Handbots from "The Girl Who Waited", which would be made shortly before "Let's Kill Hitler" (but transmitted two episodes later). As such, the Anti-Bodies instead became floating, tentacular automatons.
26. River Song is twice named after herself. First Amy names her baby "Melody" after her friend Mels. Then River asks Amy who River Song is, and she shows her an image of herself from the archives of the tesselecta.
27. River's line about "taking the age down a bit" comes to full fruition towards the end of her life. Alex Kingston's last appearance in the role, in "The Husbands of River Song", occurred several years after she filmed the character's first appearance and demise in "Silence in the Library". From River Song's perspective, "The Husbands of River Song" takes place immediately before "Silence in the Library", which means in the intervening time between the two episodes (the 24 years spent with the Twelfth Doctor), River goes from the oldest she'd ever looked, to the youngest she'd ever looked.
28. When the Doctor is dying in the TARDIS he turns on the voice interface and when it shows him he says "no no be someone I like." The voice interface then turns into Rose Tyler before he says "give me guilt" and then it turns into Martha Jones and he says "more guilt" and it turns into Donna Noble. Rose, Martha, and Donna were all companions of the tenth Doctor, whose lives were greatly changed by the Doctor.
29. Mels drives up in a stolen Corvette. This type of car was popular among American astronauts in the 1960's, partly due to a discount they received on the vehicle from a local dealer. The car is a clue that Mels is the "Impossible Astronaut" who is responsible for killing the Doctor.

Night Terrors

1. In the scene in which Alex and the Doctor are in the kitchen they open and close the fridge as they are talking. This was not in the script, but improvised by Matt Smith and Daniel Mays on set.
2. One change made at a late stage was the elimination of a running gag about door-to-door religious solicitors actually being aliens.
3. The Doctor emphasises his age frequently in the episode, this is a thematic contrast with the core ideas of childhood fears and the toy imagery.
4. The landlord, Purcell, was inspired by a gym teacher who had terrorised Mark Gatiss in his youth.
5. Daniel Mays was drawn to the story because of the family element. He has a young son like George.
6. The story was originally set in a hotel hosting a psychiatric conference, where the patients' phobias would be made manifest. However, this was very similar to "The God Complex". Steven Moffat suggested setting it in an apartment complex.
7. One of the children's stories the Doctor mentions, Snow White and the Seven Keys to Doomsday, shares its title with a story in the then-recently published Doctor Who The Official Annual 2012. Had Night Terrors aired as originally planned in the first half of the season, the story would have been published afterwards (suggesting a probable tie-in with the episode).
8. This episode had the working titles House Call and What are Little Boys Made Of?
9. This is one of only a handful of Doctor Who episodes where no one dies. Several people are transported to the dollhouse and turned into peg dolls, but they all revert back to their normal human selves by the end of the episode.
10. Mark Gatiss had previously worked with Daniel Mays in Funland (2005) and purposely inserted the line "Maybe later" into the script as it had been "a bit of a catchphrase" for the two on Funland. However, Mays did not notice the reference.
11. This was originally going to be the fourth episode of the series, but was moved to the second half as Steven Moffat felt that the first half was "too dark". This necessitated minor changes to the episode. A scene with Madame Kovarian was removed, and the ending with the data file from Let's Kill Hitler was added. This means Karen Gillan, when she filmed the episode, was in fact performing as the Ganger version of Amy. The Doctor's line at the end of the episode "Well, it's good to be all back together again, in the flesh" referring to Amy's recent turn into a peg doll was written with the intention of also applying to Amy being a Ganger.
12. During post-production, Steven Moffat came to the conclusion that, though the Peg Dolls were appropriately creepy while stationary, they were less effective as they moved silently through the doll's house. He suggested that they be heard to constantly recite nursery rhyme dialogue in children's voices.
13. Mark Gatiss drew upon his fear of dolls for this episode. He was especially interested in peg dolls, which he said were "the stuff of proper nightmares".
14. The actors portraying the dolls were choreographed to move with stiff legs but swing their arms.
15. At one point, it was thought that the story might run simultaneously with another episode. As such, Gatiss focussed his storyline on the Doctor, with his companions kept off-screen for much of the episode after being drawn into the doll's house.
16. The scene in which Purcell sinks into the carpet was filmed with Andrew Tiernan on a hydraulic platform that lowered him into green-coloured liquid, that acts as a chromakey (green screen), for when he is composited into the carpet pattern of the background footage so that it looks like he is sinking into the carpet.
17. The country house of Dyrham Park was chosen because of its staircase and checked flooring. The antiques were stripped out of the building and replaced with "child-like" furniture that was placed to look as though it had been played with.
18. Mrs. Rossiter getting sucked into the mound of garbage bags stemmed from Mark Gatiss' fear of trash being riddled with vermin.

The Girl Who Waited

1. Originally an older actress was going to play Older Amy, but Karen Gillan insisted on playing Older Amy with the aid of prosthetics and it was decided Karen Gillan playing both characters would be more believable. Gillan developed different body-language, vocal range and attitude for the new individual, whose character has changed after being left behind and in danger. To achieve this, Gillan studied with a voice coach and movement coach. Gillan also wore a padding which affected her movement and she spent hours in makeup.
2. Executive producer Beth Willis insisted that Amy's speech about how Rory was the most beautiful man she ever met made it into the final version.
3. The cast list for this episode is the shortest of any full length episode of the modern series. Considering the classic series, it is second only to The Edge of Destruction for least cast members.
4. When the Doctor looks for the glasses, a small tape player looking device activates on the TARDIS console and the 1963 Doctor Who theme can be heard, played backwards.
5. Tom McRae called this his "most accomplished piece of plotting ever".
6. Tom McRae decided to make the sets all white in color.
7. When Older Amy stabs her samurai sword in the face of a Handbot, the Handbot beeps like R2D2 from Star Wars (1977).
8. There's a reference to there being a Disneyland on the planet Klom, which Appalappachia's Roller Coaster Zone has been modeled after the Warp Speed Death Ride Rollercoaster. Klom is the home world of "Absorbaloffs"-- the species of Mr. Kennedy from "Love and Monsters" in season 2. Klom is also the planetary neighbor of Raxicoricofallipatorius, home of the Slitheen. Klom is also one of the worlds stolen by the Daleks in the 4th seasons "Stolen Earth" 2 part finale.
9. The lobby where Amy first encounters the Interface is identical to the lobby of the New New York Hospital seen in "New Earth".
10. The Handbots were originally envisaged as cloaked entities whose hands emerged from the folds of their robes.
11. Working titles for this episode included The Visitors' Room, The Visiting Hour and Kindness. Despite many reports to the contrary, there was no late change to the adventure's title and at no point was it ever called The Green Anchor.
12. Was watched by six million viewers on BBC One.
13. A deleted scene featured a Handbot's hand being cut and continuing to walk by itself.
14. Older Amy was modeled after Scathach n-'Uanaind, a red haired Scottish warrior woman and martial arts teacher from Celtic mythology.
15. Like the future Series 8 story "Kill The Moon". "The Girl Who Waited" is about The Doctor forcing his companion to make a choice which only the companion can make. The Doctor forces Rory to choose which version of Amy he wants, due to the TARDIS not withstanding the paradox of two versions of Amy Pond and in "Kill The Moon" The Doctor abandons Clara on the moon, so she can decide the fate of humanity.
16. In one draft of the script, the scene near the end in which Rory and the two Amys race to the TARDIS did not include Rory in person; he was watching the scene from the lens.
17. This is the second time Amy Pond wields a sword. In Curse of the Black Spot Amy wields a pirate sword. Here, Older Amy wields a samurai sword.

The God Complex

1. Matt Smith called David Walliams "hilarious" and found it hard to take him seriously, as when he was in his prosthetics for the part he resembled a giant mole.
2. David Walliams' prosthetics took two hours to apply.
3. The pictures seen on the walls throughout the episode show various aliens the Doctor has encountered such as Silurian, a Sontaran, a Judoon and a Sister of Plenitude (cat nun).
4. Toby Whithouse was more pleased with "The God Complex" than "School Reunion" and "The Vampires of Venice", his previous Doctor Who scripts, as the tone was darker which he was "more comfortable" writing.
5. Eager to avoid the cliché of an eerie old Victorian hotel, Toby Whithouse drew upon dreadful family vacations of his youth and instead opted for a tacky 1980s establishment.
6. David Walliams was asked to guest-star in the episode in an email and he agreed, having been a fan of the show. He had previously been a candidate to play The Tenth Doctor.
7. Rory's favorite car--as gifted to him from the Doctor--is a 1968-1971 Jaguar E-Type Series 2 roadster.
8. At the time of the script read-through, Lucy Hayward's name was "Lucy Miller". It was ostensibly changed so as to avoid conflict with Lucie Miller, the long-term audio companion of the Eighth Doctor.
9. Originally, an additional human character was Edward, a conservative blowhard who placed his faith in authority. To provide more variety, Edward evolved into the alien Gibbis, who exhibited more extreme and comical versions of the earlier character's traits.
10. At one point the Doctor holds a solved Rubik's Cube. It seems he finally solved the one that stumped him two episodes previously in "Night Terrors."
11. This episode takes place in 2011.
12. David Walliams had been offered to play the Tenth Doctor when Christopher Eccleston left the series, but was not able to take the role due to taking his hit BBC comedy show Little Britain (2003) (TV Series) live on tour. Matt Lucas, David Walliam's comedy partner and co-creator of Little Britain (2003) (TV Series) later joined the series as Nardole, companion to The Twelvth Doctor (Peter Capaldi).
13. Amy's room is #7, which is her age when she first met (and waited for) the Doctor.
14. Toby Whithouse wanted to illustrate examples of faith besides the purely religious. Hence Joe was associated with luck and Howie with conspiracy theories. Nonetheless, the writer also intended to include a prominent and sympathetic character who would exhibit a more traditional faith in God. Although Whithouse was not particularly religious himself, this would buck the often cynical trend in modern fiction of portraying devout individuals in a negative light. He considered having this character be a Christian, but felt it would be more interesting to portray a different religion, inspiring Rita's adherence to Islam.
15. The Doctor's room is #11. Matt Smith is the 11th Doctor.
16. The Doctor fears that he will either get Rory and Amy killed or have to watch them die. These themes were also touched on in "The Vampires of Venice" and "School Reunion" respectively. Both episodes were also written by Toby Whithouse.
17. The idea to have a Minotaur be the monster came from Toby Whithouse's love for Greek mythology.
18. You can see the contents of the Doctor's room in the reflection of his eye.
19. The front door of the house The Doctor gives to Amy and Rory is painted TARDIS blue.
20. A late change came when executive producer Beth Willis voiced her concern that the story relied too much on abstract concepts. To take better advantage of the hotel setting, Toby Whithouse introduced the notion of there being a room assigned to each denizen which contains his or her worst nightmare. This was partly inspired by his work on Being Human (2008), where the third season premiere had depicted characters in Purgatory and suggested the notion that every person has his or her own version of Hell.
21. The symbols on the computer, when the prison reverts to it's original shape, are the same as the ancient language in the Satan Pit 2 parter from series 2.
22. When Amy protests the Doctor's decision to stop traveling with her and Rory, the Doctor counters, "What's the alternative? Standing over your grave?" This turns out to be foreshadowing of Amy's departure in "Angels in Manhattan," where the Doctor does in fact stand over Amy's grave after she and Rory are permanently sent back in time by the Weeping Angels.
23. The contents of the Doctor's room are later revealed in the Eleventh Doctor's swansong, The Time of the Doctor, where it's shown that it's the crack in reality that was the main arc in his first series.
24. Toby Whithouse originally envisioned Amy and Rory moving into an idyllic cottage, reflecting the fairytale theme which Steven Moffat had woven into the Eleventh Doctor's era.
25. One of the rooms seen is called the "Pasiphae Spa." In Greek mythology, the mother of the Minotaur is called Pasiphae. The monster in this episode is modeled after the Minotaur.
26. Steven Moffat originally pitched the episode to Toby Whithouse for the previous series with the idea of a hotel with shifting rooms. However, as production continued, Moffat thought that there were too many instances in which the characters were running through corridors in that series, so Whithouse wrote "The Vampires of Venice" instead.

Closing Time

1. James Corden, who was about to become a father, learned tips from the mothers of the babies playing Alfie.
2. Seven babies and two infant dolls were used to portray Alfie.
3. The perfume ad that Amy is seen in is for Petrichor perfume. Petricor means the smell of dust after rain. The tagline for the ad is "for the girl who is tired of waiting", the Doctor frequently calls Amy "The girl who waited".
4. The Doctor's line reaction to seeing Craig's flat - "Oh, I see you've redecorated! I don't like it" - is an homage to The Second Doctor in "The Three Doctors" and "The Five Doctors".
5. The Doctor's ability to converse with Alfie came late in development. Steven Moffat came up with the idea for "A Good Man Goes to War".
6. Daisy Haggard's reduced role as Sophie in the episode was due to her role in the play Becky Shaw at Almeida Theatre in London.
7. At one point the Doctor says to Craig, "Not a rat, a cybermat." This line echoes the words of The Fourth Doctor in The Revenge of the Cyberman in 1975.
8. Much of the episode was filmed in a department store in Cardiff. As the store had to be closed, they filmed over four or five nights, sometimes going until 6:00 in the morning. Steve Hughes said it was a "drain" on the production team, while James Corden recalled it made the cast and crew "lightheaded" and "hysterical".
9. Actress Lynda Baron (Val) has prior history with Doctor Who. Previously playing the villainess Captain Wrak during the fifth Doctor era in the story Doctor Who: Enlightenment: Part Four (1983). She also sang The Ballad Of the Last Chance Saloon in the William Hartnell serial The Gunfighters.
10. Petrichor, the name of the perfume advertised by Amy, was one of the passwords used to get into the secondary Tardis control room in The Doctor's Wife.
11. The Doctor is referring to K9 when he says "Robot dog - not as much fun as I remember.".
12. Keen to place the Doctor and Craig's escapades in a mundane, everyday environment, Gareth Roberts considered settings such as a hospital, a police station and a supermarket before finally settling on a department store.
13. This episode takes place from April 18 to April 20, 2011 and in the 52nd Century.
14. Three versions of the Cybermat were made. The first was simply a "stunt double" which did not have teeth and was meant for being thrown around or laid still. The second was a cable-controlled "close-up" version that had teeth and thrashed, and was used for when the characters handled it. The third was radio-controlled to dash along the floor.
15. BBC Radio 1 DJ Greg James appears in a non-speaking cameo role, as a man shopping for lingerie. His character was nicknamed "Carlos".
16. Working titles for this episode included Carry-On Lodging, Everything Must Go, Three Cybermen and a Baby and The Last Adventure.
17. Craig and Sophie's child was originally a girl, first named Grace and later Tess.
18. Amy appears in an advertisement for Petrichor perfume. Karen Gillan (Amy) was a fashion model before becoming an actress.
19. First time the cyber men are the main villains for an episode since Matt Smith became the Doctor.
20. A scene in the stock room in which a warehouseman is killed by a Cyberman while assembling a mannequin was cut.
21. Alfie (through the Doctor) criticizes Craig's singing voice. In real life, James Corden is an accomplished singer having starred in several musicals.
22. Like the BBC Three hit sitcom, Two Pints of Lager and a Packet of Crisps (2001-11). Both penultimate episodes of their sixth series that have the same episode title, Closing Time.
23. When the Doctor disables the cybermat is the first time the Doctor has ever used the sonic screwdriver as a gun.
24. This is the first television story since the series revival in which the Cybermen are not armed with any type of weaponary. The Cybermen who are seen have visible gaps in their forearm armour where they would normally have blasters and they are not seen electrocuting anyone.
25. Matt Smith broke a Cybermat prop when he hit it with a frying pan in the scene where Craig is being attacked, and it was subsequently repaired with tape.
26. It was Gareth Roberts' idea to bring back the Cybermen, because there were no other returning monsters in the series and he thought "there should be a sense of history about the Doctor's final battle to save Earth before he heads off to meet his death".
27. The "app" for disabling the Cybermat used one of the "bonus sounds" found on the toy version of the Eleventh Doctor's sonic screwdriver, unheard on the show until now.
28. The window of the sliding door in the house that the Doctor jumps through to save Craig from the Cybermat was too small, so the production team built another one. The new door was too big for shatterglass. Instead, glass that breaks into chunks was used, wired with a small explosive that would crack the glass when the stuntman jumped through it.
29. The final two scenes - the three children remembering their encounter with the Doctor, and Madame Kovarian's reunion with River Song - were written by Steven Moffat.
30. Gareth Roberts' first draft was much different. The disappearances were not a new phenomenon, but occurred every few decades, to be accompanied by strange graffiti. Much was made of the history of a market which had been held for centuries on the site of the shopping centre; the Cybermat would have been found entombed within its foundation stone. It transpired that the being responsible for the kidnappings was a Cyberscout - referred to as "the Guardian" - which had operated on automatic for centuries, with the graffiti part of its reconnaissance procedure. Over the years, the Guardian had gradually replaced its defective parts with human limbs and organs when it periodically awoke from dormancy. Now nothing was left of the original Cyberman, and it was protecting Colchester from the other Cybermen which lay underground in suspended animation. After an ending in which Craig destroys the Cybermen with a wrecking ball was dismissed, the climax subsequently hinged on the Doctor transmitting the Guardian's personality into the reactivated Cybermen, overwhelming them.
31. The Cybermats were redesigned to be more high-tech. The top was designed to recall the head of a Cyberman, and piranha-like teeth were added to suggest that they were converted animals, just as Cybermen were converted humans.
32. Part of the nursery rhyme that was heard "Night Terrors" is sung by Madame Kovarian, with new lines.

The Wedding of River Song

1. The Doctor learning of The Brigadier's death was a tribute to Nicholas Courtney, who passed away the same year. The episode also contains scenes in which "everybody was wearing an eyepatch", a reference to the alternate universe Brigadier in "Inferno". Furthermore, Amy says to the Doctor "We'll be in Cairo soon", Cairo being Courtney's place of birth. Steven Moffat said of the reference, "In a story about the Doctor going to his death, it seemed right and proper to acknowledge one of the greatest losses Doctor Who (2005) has endured."
2. Brigadier Alistair Gordon Lethbridge-Stewart is said to have died in his sleep peacefully at a nursing home. In "Battlefield", The Seventh Doctor stated that this was exactly how his old friend would pass away.
3. The brief appearance of Simon Callow as Charles Dickens marks the first time that any character (other than the Doctor or River Song) from series 1-4 has appeared on-screen in an eleventh Doctor story. Callow previously played Dickens in the first season story "Doctor Who: The Unquiet Dead (2005)".
4. This is the first series finale of the revived series not to be a multi-part episode.
5. Amy's confrontation with Madame Kovarian, a scene which shows what she might have been like had she not met the Doctor, was also added into the script later.
6. This is the second time the Eleventh Doctor is shown with facial hair. He was previously depicted with it Doctor Who: Day of the Moon (2011) which was directly tied with this episode.
7. The Doctor calling the retirement home and learning Brigadier Lethbridge Stewart passed away was added in the script by Steven Moffat as tribute to Nicholas Courtney whom passed away during production on Series 6 on 22nd February 2011.
8. The cast found working with the eye patches strange as they had to act with one eye. Alex Kingston remarked that it made her "slightly dizzy".
9. Originally, the script did not include the brief scene with a Dalek, as Steven Moffat had intended to rest the Doctor's most famous adversary for the sixth series.
10. "Live Chess" came because Steven Moffat wanted to make chess - which he called "one of the most boring games in the world" - into a dangerous spectator sport.
11. The script called for an Indiana Jones style tunnel for the Headless Monks' chamber, but as that kind of location was not available in Cardiff a set was built instead.The skulls were hand-crafted and required a lot of preparation, so it was one of the first things started for the episode's production.
12. Mark Gatiss is credited under the pseudonym "Rondo Haxton", a homage to the American horror actor Rondo Hatton who Gantok's look is based on.
13. Steven Moffat described the episode as "a big roller coaster ride of Doctor Who (2005) madness".
14. This episode takes place on April 22, 2011 and in the 52nd Century.
15. At time stamp 39:52 showing the earth from space, there in the clouds is an image of a horse with head left, bucking off the Doctor wearing the cowboy hat. His head is to the right.
16. In post-production, one major change to the episode - which acquired the title The Wedding Of River Song - was the introduction of the "eye drive" terminology. Originally, these devices had been called "data cores", but Steven Moffat came to worry that viewers might not know that this was referring to the eyepatches.
17. In the back-story of Madame Kovarian (Frances Barber), the main antagonist in Series 6: she was a member of the Papal Mainframe space church, which Tasha Lem (Orla Brady) is the Mother Superior, but left the Papal Mainframe and became a servant of the Silence religious order.
18. The cast and crew had to perform some scenes with only a vague suggestion of the dialogue from Steven Moffat's suggestions when deciding the overall story arc. This was due to the fact that the script was a last minute rush that only had one draft as Moffat was also busy with Sherlock. This is partly the reason as to why the story doesn't make sense and some of the plot points have no relevance other than to extend the run time.
19. When Amy tells her name to Winston Churchill ("Pond. Amelia Pond"), she stresses her first name in much the same way James Bond introduces himself throughout the various movies. This is fitting, since the time-slipped Amy is some sort of important special operative, similar to James Bond.
20. Simon Callow and Ian McNiece both co-starred in "Ace Ventura When Nature Calls".
21. Meredith Vieria is a well known American TV news and talk show host. She first came to prominence on 60 Minutes in the 1980s. She was also one of original panelists/co host of The View (1997). Her appearance on Doctor Who maybe an indication that the series is becoming known to Americans.
22. All the armed security personnel in the pyramid are wearing eye drives over their right eye, but they are also all right handed given by the way they hold their rifles, this would make aiming impossible as their vision would be impaired.
23. Gideon Vandaleur, The Silence envoy in The Wedding of River Song (#6.13) wears a Viking helmet and armor.
24. During the conversation between The Doctor and River where they ultimately say their vows, a theme is playing in the soundtrack that has recurred throughout this season as a theme for River. If you listen carefully, the tune repeats itself in slightly different ways, morphing into what can clearly be heard as the common bridal tune "Here Comes the Bride", revealing that the composer, Murray Gold, had this inspiration in mind the whole time. His rendition of the tune is slow and sad, however, reflecting the pain that comes along with River's love for The Doctor.
