Doctor Who

Season 3

Smith and Jones

1. When Martha and The Doctor first step out onto the balcony and Martha says that the cause must be extra-terrestrial, she refers to a cousin, named Adeola. Freema Agyeman played the character Adeola in Doctor Who: Army of Ghosts (2006). It was this role that convinced the directors to choose her to play Martha.
2. The line "Judoon platoon upon the Moon." was written as something of a joke towards David Tennant. The Scottish accent, which is Tennant's natural one, makes it difficult to pronounce the sound/syllable "-oon" in an English accent.
3. The Doctor is wearing the same pyjamas that he did in Doctor Who: The Christmas Invasion (2005).
4. The Doctor for the first time reveals that he has (or, rather, had) a brother.
5. When the Judoon are first cataloging all the patients, The Doctor mentions that the hospital has a shop. In Doctor Who: New Earth (2006), The Doctor expresses his disappointment that there isn't a shop in the hospital with Rose.
6. Mr. Saxon references: 1. Referenced on a television news report about the disappearance of the hospital. 2. An election campaign poster visible on a wall before Martha enters the TARDIS for the first time.
7. The working title for this episode was Martha. This was intended to parallel Doctor Who: Rose (2005).
8. The original special effect for the Judoon weapons - in which the victim's skin would be seen to boil away - was too frightening, and so this was altered.
9. Paul Kasey had to be replaced in some scenes because of scheduling conflicts so Ruari Mears played the Judoon Captain in some scenes.
10. A set piece in which the Doctor and Martha flee from the Judoon by scaling down the outside of the hospital in a window cleaner's cradle had to be excised due to its length, but was later resurrected for Doctor Who: Partners in Crime (2008).
11. The location of the fictional Royal Hope Hospital in which this episode is set, is in real life St. Thomas' Hospital in London.
12. Adjoa Andoh previously played Sister Jatt in Doctor Who: New Earth (2006).
13. Anne Reid previously played Nurse Crane in Doctor Who: The Curse of Fenric: Part One (1989)/Doctor Who: The Curse of Fenric: Part Two (1989)/Doctor Who: The Curse of Fenric: Part Three (1989)/Doctor Who: The Curse of Fenric: Part Four (1989), involving Haemavores. In this she plays the Plasmavore. Both are variants on Vampires or are possibly the same thing.
14. The Judoon later appear in The Sarah Jane Adventures (2007), where they are hunting another alien fugitive, and also ban Clyde Langer and Rani Chandra from leaving Earth after interfering with their plans.
15. The Doctor sarcastically mouthing along when Martha says "It's Bigger on the Inside!" was an ad-lib by David Tennant.
16. For a number of drafts, a key element of the adventure involved the Doctor and the Plasmavore each trying to reach the hospital basement, where the TARDIS was hidden. Russell T. Davies subsequently felt that this was too banal a plot strand, however, and decided to have the time machine left behind on Earth instead.
17. When the Doctor first meets with Martha on the moon, most of his initial dialogue with her is in the forms of questions - asking her her views on what has happened and what is happening. This reflects the dialogue Martha and the other student Doctors were having with the consultant when doing the ward rounds. The Doctor is prompting Martha to offer her diagnosis.
18. After Martha discovers the alien patient, she returns to the Doctor to tell him she found the fugitive alien in the hospital. When the helmeted slab drones begin chasing her, the Tenth Doctor grabs her hand and tells her, "Run!" This scene echoes the scene in Doctor Who: Rose (2005) where the Ninth Doctor grabs Rose's hand and tells her, "Run!"
19. Martha becomes the first character to use a mild profanity on the series with the line, "We're on the bloody moon!"
20. With the action taking place in a hospital, Russell T. Davies chose to name its administrator after Mr Stoker, a character in the family programme Children's Ward (1989). Given the presence of a blood-sucking creature in the episode, however, this was misconstrued by the design team, who assumed that Davies was referencing Dracula author Bram Stoker. As a result, the character's office door bore the legend "B Stoker".
21. The first appearances of Martha, Leo, Tish, Francine and Clive Jones.
22. The phrase "burn with me" is used again in Doctor Who: 42 (2007).
23. The episoded featured the first extra-diegetic use of hip hop in the show's history, in the form of Arrested Development's "Sunshine" to introduce Martha and her family. Due to a quirk of release scheduling, this was also the first time that the series served to premiere a song in the United States. "Sunshine" wasn't released in America until Halloween 2007, months after the US release of Smith and Jones.
24. In the book "Doctor Who: The Inside Story", a piece of concept art by Peter McKinstry shows a concept sketch of a "burnt out" sonic screwdriver. The book came out some time in advance of the airing of the episode.
25. Just for perspective: A normal MRI is less than 10 Tesla, most are less than 5 Tesla.
26. On the channel Watch, the execution of the person who attacked the Judoon with a vase was cut out from the episode.
27. Martha's "welcome aboard" scene is almost identical to that of Peri Brown in Doctor Who: Planet of Fire: Part Four (1984). In both cases, The Doctor and the companion fall on the console before The Doctor makes his welcome.
28. This episode takes place in 2008.
29. This is the first story since Doctor Who: Rose (2005) to lack a pre-credits sequence.
30. Exclusive previews of the episode were also held in five venues across Wales. The Cardiff Bay Odeon, Swansea Odeon, Wrexham Odeon, Aberystwyth Arts Centre and Pwllheli Neuadd Dwyfor all screened it on the morning of 31st March, hours before the television broadcast.
31. The titular names "Smith" and "Jones" are a fitting homage to Men in Black (1997), which also has several undercover aliens posing as humans.
32. When Martha asks what the Plasmavore is doing on Earth, The Doctor says, "Hiding, on the run. Like Ronald Biggs in Rio de Janeiro." Ronald Biggs was an English criminal who helped plan and carry out the Great Train Robbery of 1963. He was convicted and jailed, but escaped after 15 months. He hid out in Australia for 4 years, before going to Rio de Janeiro, Brazil, which did not have an extradition treaty with the UK.
33. Martha is the Doctor's first black companion, and in fact, the first non-white companion.
34. In Doctor Who: Turn Left (2008), the events of this episode are revisited. In that timeline, Martha, Sarah Jane Smith, Luke Smith, Maria Jackson and Clyde Langer are killed stopping the Plasmavore as the Doctor died during the events of Doctor Who: The Runaway Bride (2006) and Oliver Morgenstern is the only survivor.
35. In final moments of this episode, the Doctor is describing his action as he begins to pilot the Tardis. He says " hand brake off", then we hear the telltale sound of the Tradis dematterilising. In a future episode, River Song is piloting the Tardis and it makes no sound. When asked why, she replies " The Doctor leaves the hand brake on" , implying the signature grinding is on purpose.

The Shakespeare Code

1. In response to a flirtatious remark from Shakespeare towards him, the Doctor says, "57 academics just punched the air." William Shakespeare's Sonnet 57 is one of many believed to have been written to a man, and contains lines referring to time: "I have no precious time at all to spend,/ Nor services to do, till you require./ Nor dare I chide the world-without-end hour/ Whilst I, my sovereign, watch the clock for you."
2. "Love's Labours Won" is an actual lost William Shakespeare play, the text of which has never been located. Some scholars believe that it is not really lost, but is simply a working title for one of his romantic comedies such as As You Like It, Much Ado About Nothing, or All's Well That Ends Well, all of which have interchangeable titles which don't describe the play's content very well. Or even The Two Gentlemen of Verona, Twelfth Night, or The Taming of the Shrew, which all revolve around exhaustive efforts in pursuit of love.
3. When he emerges from the prop storehouse, The Doctor is carrying a prop that reminds him of a Sycorax (the evil aliens from the 2005 Christmas special, Doctor Who: The Christmas Invasion (2005). Shakespeare tells him that he likes the word, and will have that off him as well. Sycorax is a posthumous character in William Shakespeare's play "The Tempest".
4. This episode originally aired a few months before the release of the final Harry Potter novel, making the J.K. Rowling references and the Doctor's line "Wait until you read Book 7." particularly memorable at the time.
5. The Doctor's quote of Dylan Thomas' famous villanelle, "Do not go gentle into that good night" is likely an in-joke, as Thomas was heavily influenced by William Shakespeare as a youth. There are distinct resonances with King Lear in the poem, which is even written in modified iambic pentameter.
6. In Doctor Who: City of Death: Part Four (1979), The Doctor claimed to have met William Shakespeare, however his behavior upon meeting Shakespeare in here suggests he's never met the man before. Writer Gareth Roberts, in an interview, indicated that lines were written to reference the City of Death meeting, but were cut so as not to confuse new viewers.
7. Christina Cole kept her character's teeth.
8. This is one of the few 3rd season episodes NOT to include a Mr. Saxon reference.
9. Phil Collinson called this episode the "most expensive ever", because of the large amounts of CGI and filming in Warwick, Coventry and London.
10. One of few occasions where The Doctor didn't appear to use the sonic screwdriver in the episode.
11. In creating the villains of the story, Gareth Roberts considered either the Three Witches of Macbeth or the Fairies of A Midsummer Night's Dream. It was felt that the former were more iconic, and so Roberts created the Carrionites.
12. During this episode, multiple references are made to Harry Potter. David Tennant played Bartemious "Barty" Crouch, Jr. in the film adaptation of the fourth novel: Harry Potter and the Goblet of Fire (2005).
13. The Doctor and Martha watch a fiction sequel to William Shakespeare's 'Love's Labours Lost'. David Tennant played Berowne in the Royal Shakespeare Company's 2008 production of the same play. In addition, Shakespeare says "To be or not to be...oh! That's quite good." The Doctor tells him he should write that down, to which Shakespeare replies, "Maybe not. Bit pretentious?" Tennant was cast as "Hamlet" in the RSC's 2008 stage production and its television version, Hamlet (2009).
14. This is the first time The Doctor and his companion are shown sharing a bed (though platonically on The Doctor's part). It is also the first time a companion is actually shown making sexual advances (albeit subtle) towards The Doctor. (Martha's advances are defused when The Doctor starts talking about Rose.)
15. The Doctor finds Shakespeare backstage, rubbing the top of his head where he had hit it when he fell on stage. The Doctor tells him to stop rubbing it or he'll go bald. The most authentic images portraying William Shakespeare show him to be a man who is balding on the top of his head.'
16. The Doctor says that Martha Jones is from the country of Freedonia. This is the name of the fictional country in Duck Soup (1933).
17. Martha asks The Doctor about changing history if she stepped on a butterfly. This is a reference to the Ray Bradbury short story "A Sound of Thunder," where a character steps on a butterfly in the past and changes the future.
18. Working titles for this episode included Love's Labours Won and Theatre of Death.
19. Shakespeare's daughter, Susanna, was to have appeared at one stage.
20. Upon arriving at the inn where The Doctor and Martha meet Shakespeare, Martha attempts a timely appropriate accent, to which The Doctor says "No...don't do that." The Doctor previously said this to Rose in Doctor Who: Tooth and Claw (2006), exactly one season previously.
21. Wiggins was named after Doctor Who (1963) fan and William Shakespearean professor Martin Wiggins and Dolly Bailey is a reference to David Bailey, who has written various Doctor Who short stories and audios in Big Finish Productions' range of Bernice Summerfield dramas.
22. Lilith's name is only said once throughout the whole episode. It is only said in the beginning when the young man tells Lilith that her house is foul. Her name is not even said by Bloodtide, Doomfinger or Lilith herself.
23. Lilith was named after a storm demon in Mesopotamian mythology who is also mentioned in Judeo-Christian tradition.
24. The episode bears some similarities to the previous Gareth Roberts' penned comic story featuring William Shakespeare and the Ninth Doctor, A Groatsworth of Wit, which may have provided some of the inspiration for this episode.
25. It is implied that Shakespeare is bisexual. Biographers of William Shakespeare have long debated this possibility.
26. William Shakespeare and Queen Elizabeth I, then played by Hugh Walters and Vivienne Bennett, had previously appeared in Doctor Who: The Executioners (1965).
27. The use of a name having power ties in to many things, and has subtle references to the William Shakespeare quote 'What's in a name? A Rose by any other name would smell as sweet.' This refers to the replacement of Rose by Martha as The Doctor's sidekick.
28. This episode takes place in 1599.
29. The character Mr. Lynley, Master of the Revels, is based on Sir Edmund Tilney, who held that office 1579-1610. This job involved reading all plays submitted to the London theatres, to make sure they had no subversive content. Very little is known about Tilney, who is often portrayed in William Shakespeare-related fiction as something of a buffoon. Arguably his most famous portrayal is Shakespeare in Love (1998), where he is played by Simon Callow who played Charles Dickens in Doctor Who: The Unquiet Dead (2005).
30. Title and plot elements are a homage to "The DaVinci Code".
31. Six years later in Doctor Who: The Day of the Doctor (2013) we got to see the tenth Doctor getting married to a younger version of Elizabeth I. Their marriage might explain why the older Elizabeth seen here wants to Doctor executed.
32. When Shakespeare improvises to close the portal and stalls out, Martha shouts "expelliarmus", echoed by the Doctor and Shakespeare. Then the Doctor says "Good old J.K.!" This is another Harry Potter reference, as this word was invented by J.K. Rowling for that series.
33. The ending featuring Queen Elizabeth was Russell T. Davies' idea. It is taken from Gareth Roberts' Big Finish Audio play "The One Doctor", which featured The Sixth Doctor and Mel Bush.
34. Initially, Bloodtide and Doomfinger were referred to as Lilith's sisters rather than her mothers. Their dispatching of Peter Streete was at one point envisioned as being much more complex, with Streete being sucked down into his bed.
35. During the death of Shakespeare's manager, the music becomes very similar to the Satanic chanting during similar death sequences in The Omen (1976). David Tennant later starred in Good Omens (2019), which spoofs the basic concept of The Omen.

Gridlock

1. As The Doctor and Martha exit the TARDIS onto New Earth, The Doctor pulls an arrow out of the TARDIS door, an arrow which Queen Elizabeth's men shot at them at the end of the previous episode, Doctor Who: The Shakespeare Code (2007).
2. The couple seen in the pre-credit sequence are made up to resemble the father and daughter in the Grant Wood painting, "American Gothic".
3. The Macra first appeared in Doctor Who: The Macra Terror: Episode 1 (1967), and the Doctor's description of Gallifrey is identical to that given by Susan in Doctor Who: A Desperate Venture (1964) within "The Sensorites" serial.
4. Russell T. Davies has said this will be the last episode of the series to be set in the year 5 billion.
5. In devising an appropriate aquatic monster, Russell T. Davies had considered both a Godzilla-like reptile and a giant octopus before using the Macra.
6. Alice and May Cassini are the first homosexual married couple featured in the series.
7. This episode had a working title of Chasing Fumes.
8. The vehicles seen "driving" on the motorway are designed to look like the iconic Volkswagen Type 2-also known as the VW Bus in the USA and the VW Camper in the UK. The Type 2 was world-renowned for its role in cheap, reliable and comfortable long-distance driving-used and lived in much like the ones seen stuck on the motorway.
9. Murray Gold wrote a different hymn with choral voices for the finale, but it sounded too much like part of the soundtrack score rather than the travelers singing it. Abide with Me was used instead.
10. One story strand excised involved baby Macra, which were feeding upon the drivers of the Motorway's lowest level.
11. Originally, the action would have been split between the wealthy inhabitants of the Overcity, the downtrodden denizens of the Undercity riding the Motorway, and the gargantuan creatures living in New Earth's oceans.
12. Brannigan's appearance was taken directly from Ratz, a character created for Live & Kicking (1993).
13. When The Doctor asks how long they'll keep on driving, Brannigan replies "'til the journey's end". Doctor Who: Journey's End (2008) is the title of the fourth series finale.
14. Russell T. Davies drew plenty of inspiration from 2000AD. The overcrowded New New York is based on Megacity One, from Judge Dredd, while the bowler-hatted businessman was inspired by Max Normal. Sally Calypso was inspired by reporter Swifty Frisko from The Ballad of Halo Jones.
15. Sally Calypso was Erika Macleod's first and only acting role.
16. This episode takes place in 5 000 000 053.
17. There are several similarities to fellow sci-fi series Futurama (1999). Both are set in the distant future, in a city called New New York - with hover cars that despite being able to fly are often stuck in traffic the same as modern traffic jams - and both feature a character named Brannigan who pilots a flying ship (Futurama's recurring character Captain Zapp Brannigan is a bumbling, misogynist, Captain Kirk-like space captain).
18. The role of Brannigan was offered to David Threlfall.
19. Despite the fact that the episode takes place in New New York, almost everyone speaks with UK accents. Of course, since the city is not in America, but rather on an entirely different planet, it's not beyond reason that the population of this city, and perhaps the majority of the planet, speak with UK-inspired accents.
20. The Face of Boe's final message was actually due to be given to the Doctor at the end of Doctor Who: New Earth (2006), but was removed and saved for this story instead, because the death of two recurring characters in that story would have been too bleak.
21. When Novice Hame is describing to the Doctor how the virus killed the population - except those in the sealed Motorway - she says, 'they were saved.' This idea - of being 'saved,' rather than 'safe,' will play a big part in the next series' two-parter Doctor Who: Silence in the Library (2008)/Doctor Who: Forest of the Dead (2008).

Daleks in Manhattan

1. Steven Moffat was originally going to write this serial. However, he was busy with Jekyll (2007), and so offered to write the Doctor-lite story Doctor Who: Blink (2007) to compensate.
2. Originally, much of the action around the speakeasies which proliferated during Prohibition, including having Laszlo involved with the mob. However, Russell T. Davies wanted to avoid the jazz music which would be predominant in such an environment, and so Helen Raynor came up with the Broadway and Hooverville settings instead.
3. The budget did not allow David Tennant and Freema Agyeman to go to New York.
4. This is the first time since the Daleks' debut story that one of them has actually considered leaving their shell.
5. Russell T. Davies chose Helen Raynor to write this two-parter based on the strength of Torchwood: Ghost Machine (2006), which she wrote.
6. Helen Raynor drew inspiration from the Universal Pictures stable of monster movies, which were at their zenith during the Great Depression. Frankenstein (1931) was a main inspiration.
7. Solomon called $1.00 a day slave wages. For perspective, the fortunate few who worked building the Empire State Building earned $2.00 an hour for tradesmen like masons and steel workers and $1.00 an hour for unskilled laborers.
8. Tallulah was an homage to the singer played by Jodie Foster in Bugsy Malone (1976).
9. Mr Diagoras was named for the fifth century BC Greek poet, Diagoras the Atheist.
10. The working title for the episode was originally "Daleks in New York" but was changed due to the fact that it would be easier to say Manhattan.
11. Frank is played by Andrew Garfield, who is close friends with Matt Smith, who would later go on to play the Eleventh Doctor.
12. A major set piece saw Tallulah discover a cage full of the remnants of the Daleks' failed genetic experiments, but this was dropped due to expense.
13. The Doctor mentions that New York City was originally named New Amsterdam. Freema Agyeman later starred in New Amsterdam (2018).
14. Towards the beginning, the character Solomon breaks the bread in half for the two men fighting over it. This is analogous to the biblical story of King Solomon threatening to cut a baby in half for two women both claiming it.
15. The theatre exterior that is shown at the beginning is The Majestic Theatre in New York City where the musical The Phantom of the Opera is playing.
16. This episode takes place on November 1, 1930.
17. The time-travel setting of New York in 1930 was also used in Star Trek: The City on the Edge of Forever (1967), often considered a groundbreaking story in science fiction television.
18. A snippet of George Gershwin's "Rhapsody in Blue" plays as The Doctor and Martha arrive in New York City.
19. Andrew Garfield (Frank) later starred as Peter Parker in The Amazing Spider-Man (2012) and The Amazing Spider-Man 2 (2014), which also involve New York being endangered by human hybrid menaces.
20. The cliffhanger of this episode (the appearance of a humanoid Dalek) was spoiled when the production team chose to feature an image of it on the cover of that week's Radio Times.
21. It was discovered at the last minute that no hands had been ordered for Eric Loren's costume as the hybrid Sec, and so the actor was given a pair of black gloves to wear for the scenes in which Diagoras is absorbed by Sec. Subsequently, however, it was realised that the panic was all for naught: the hands had been fabricated after all.
22. An opening TARDIS scene, in which Martha convinces the Doctor to take her on one last trip through time was cut. This matched up with the opening moments of the next story to be broadcast, Doctor Who: The Lazarus Experiment (2007), in which the Doctor finally brings Martha home.

Evolution of the Daleks

1. This is the first episode of the revived series to use the convention of the classic Doctor Who series of naming Dalek-centered serials as "(blank) of the Daleks" (Doctor Who: The Power of the Daleks: Episode One (1966), Doctor Who: Remembrance of the Daleks: Part One (1988), etc.). This convention would later be used for series 5's Doctor Who: Victory of the Daleks (2010).
2. This is the first two part story in the revived series to not feature the inside of the TARDIS.
3. A deleted scene involved the return of the Doctor, Martha and Frank to the Hooverville with Tallulah in tow, and saw the Doctor admit to Tallulah that he'd be unable to reverse Laszlo's transformation. It was cut because it had been shot too late in the day, and so the light was insufficient.
4. This episode takes place on November 1, 1930.
5. Shortly before the lightning strike the group on the top floor waiting for the elevator speak about staying away from any metal to avoid being shocked all the while they're leaning again a giant steel I-beam support.
6. Near the climax, Tallulah says, "Gammon radiation? What the heck is that?" In England a gammon is a ham that was cured like bacon is. It is commonly served for Christmas dinner.
7. The Daleks' plan involves solar flares and gamma radiation, a formula often used as a plot device in Marvel Comics. Andrew Garfield (Frank) later played Marvel hero Peter Parker in The Amazing Spider-Man (2012) and The Amazing Spider-Man 2 (2014).
8. Although set in 1930, The Doctor uses time travel privilege to throw around the term 'Genocide', which wouldn't be coined until 1944 by Raphael Lemkin.
9. Laszlo was originally supposed to die. Russell T. Davies asked Helen Raynor to alter this, as he felt the development was too depressing for the New Who ethos.

The Lazarus Experiment

1. The Doctor says, "It shouldn't take that long to reverse the polarity. I must be out of practice". "Reverse the polarity!" was the catchphrase (and strategy) of Jon Pertwee's Third incarnation of Doctor Who (1963) in the early 1970s.
2. The set piece for the capsule of Lazarus's Genetic Manipulation Device is actually the redecorated descent capsule from Doctor Who: The Impossible Planet (2006)/Doctor Who: The Satan Pit (2006).
3. An old head-cast of Vincent Price was tracked down and used by Neill Gorton to add an aged and wrinkled look to the prosthetics Mark Gatiss wore when playing the elderly Dr Lazarus.
4. Originally Professor Lazarus was working on developing invulnerable synthetic skin. This was dropped because Russell T. Davies feared that this might be part of the plot of Spider-Man 3 (2007), which was due for release around the same time the episode would likely air. The episode has plenty of Spider-Man (2002) and Spider-Man 2 (2004) references as is.
5. Mr. Saxon Reference: Throughout the episode, Mr. Saxon is brought up by Professor Lazarus, as one of his confidants and supporters of the experiment. Also, Francine Jones begs Martha not to go with the Doctor, that she's heard terrible things about him from "Mr. Saxon himself".
6. A scene cut from the episode, but included as an extra with the DVD release, reveals that the Doctor participated in the writing of the United States Declaration of Independence and in fact carries a copy of the first draft folded up in the pocket of his dinner jacket.
7. This is the first time since Doctor Who: Smith and Jones (2007) where Martha is wearing different clothes other than her jeans and leather jacket.
8. In creating a 'mad scientist' story, Stephen Greenhorn was inspired by The Fly (1986) and The Strange Case of Doctor Jekyll and Mister Hyde. He also sought inspiration from Spider-Man villains Doctor Octopus and The Green Goblin.
9. Several of Stephen Greenhorn's initial ideas had to be discarded because they were too similar to concepts being developed either for the first season of Torchwood (2006) or (in the case of using the Thames Flood Barrier as a setting), Doctor Who: The Runaway Bride (2006).
10. Professor "Lazarus" is played by Mark Gatiss who plays Sherlock Holmes' brother Mycroft in Sherlock (2010), where "Lazarus" serves as an important password in a crucial story arc.
11. This episode takes place in 2008.
12. When The Doctor and Martha leave the elevator, the musicians are playing "The Doctor Forever" theme on the double bass.
13. The working title for this episode was The Madness Of Professor Lazarus.
14. The creature that Dr. Lazarus de-evolved into actually was very close in appearance (but not size) to the centipede and scorpion like organisms that first made their way onto land out of the sea over 470 million years ago. The first vertebrates (animals with backbones) didn't come onto land till 40 or 50 million years later.
15. Professor Lazarus quotes T.S. Eliot's 'The Hollow Men'. "Between the idea, And the reality, Between the motion, And the act, Falls the Shadow". 'Falls the Shadow' is the title of one of Virgins, Doctor Who New Adventures, starring the seventh Doctor and Bernice Summerfield.
16. Professor Lazarus was originally named Professor Anger.
17. Lazarus' demonstration is based on scenes from Sam Raimi's interpretation of Spider-Man (2002) and Spider-Man 2 (2004). The immediate previous serial Doctor Who: Daleks in Manhattan (2007)/Doctor Who: Evolution of the Daleks (2007) starred Andrew Garfield, who then played Peter Parker in The Amazing Spider-Man (2012) and The Amazing Spider-Man 2 (2014), which cover much of the same ground from a different angle.
18. In order to defeat Lazurus, the Doctor turns the amplifier of the pipe organ in the Southwark Cathedral "up to eleven". A line from the mockumentary This Is Spinal Tap (1984). Spinal Tapper Michael McKean was David Tennant's costar in Good Omens (2019).
19. The circular symbol displayed around Lazarus' lab is the same design as on The Master's ring.
20. After Lazarus dies in the Cathedral, The Doctor closes his eyes just as Martha did to Mr. Stoker in Doctor Who: Smith and Jones (2007).

42

1. In the commentary for this episode, Russell T. Davies stated that he prefers the Doctor in the blue suit when going to the future and the brown suit when going to the past.
2. "42" may also be seen as reference to the Ultimate Answer to Life, the Universe and Everything, as written by Douglas Adams in the radio series "The Hitchhiker's Guide to the Galaxy". Some of the sound effects in this episode were taken from The Hitchhiker's Guide to the Galaxy (1981) TV show. Adams also wrote scripts for several Doctor Who (1963) episodes during the late seventies. Interestingly, in one of the "Hitchhiker's Guide" books there is also a chapter where the protagonists are caught in a stolen spaceship headed for the sun.
3. This episode takes place in the 42nd century.
4. This episode ostensibly (though not quite) takes place in real time, a technique made famous by 24 (2001). The average running time of a Doctor Who episode also happens to be about 42 minutes.
5. Martha Jones gets her phone upgraded and a key to the TARDIS, two signs that she's the new companion.
6. The ship was originally called The Icarus. However, Sunshine (2007), which opened around the same time, had a ship called The Icarus II. It was renamed The SS Pentallian, after the Pentalion drive mentioned in Doctor Who: Revenge of the Cybermen: Part One (1975).
7. When the Doctor is asked about The Beatles songs, he replies, "Here comes the sun!" This is an inadvertent pun on both the spaceship hurtling towards the sun, and also the name of one of the Beatles top hits.
8. The masks worn by the possessed crewmembers were inspired by Cyclops from The X-Men. This is the final of four consecutive episodes with Marvel Comics references.
9. It was suggested that the story would be set in the same era as Doctor Who: The Impossible Planet (2006)/Doctor Who: The Satan Pit (2006), and for a time, consideration was given to including the Ood from that story, although this did not survive to the drafting stage.
10. The story originally took place in the Peony system, but it became the Toraji system following concerns that the original name would be misheard as "penis".
11. The Doctor wears his blue suit for the entire episode however, once he exits the TARDIS and is on board the spaceship, the red lighting makes it look as though he is wearing his brown suit.
12. Ashton was originally called Motta, but it was felt that this would sound too similar to Martha.
13. Riley's last name was originally Kincade. It became Vashtee because Brannigan's middle name in Doctor Who: Gridlock (2007) is Kincade.
14. A major set piece involved the Doctor scaling the exterior of the spaceship, until fears were raised about the expense it would incur. Chris Chibnall simplified this to the Doctor's efforts to reach the lever outside the airlock.
15. This was the first episode written by Chris Chibnall, who would later take over as showrunner.
16. The scene in which the Doctor promises to rescue Martha from the escape pod was inspired by The Last of the Mohicans (1992).
17. Mr. Saxon Reference: Francine works with government agents to find Martha (and thereby, The Doctor) who tell her that "Mr. Saxon will be very grateful" for her cooperation.
18. Miss Dexter makes her first appearance in this episode, although her name is not spoken. She's only referred in the credits as the "Sinister woman".
19. Michelle Collins filmed her death scene on the first day of shooting.

Human Nature

1. In John Smith's book, "A Journal of Impossible Things", sketches of previous actors who have played the Doctor are shown, marking the first time that the 2005 series has explicitly depicted the Doctors from Doctor Who (1963) and Doctor Who (1996). The actors depicted on screen were William Hartnell, Peter Davison, Colin Baker, Sylvester McCoy and Paul McGann. Images of the Journal that were published on the BBC website reveal that the other remaining Doctors, Tom Baker, Jon Pertwee, Patrick Troughton, Christopher Eccleston, and David Tennant himself, were also illustrated on the page.
2. John Smith gives the names of his parents as Sydney and Verity. This is a reference to Sydney Newman (creator of Doctor Who (1963)) and Verity Lambert (the show's first producer).
3. When Martha has returned to the TARDIS and is watching the video the Doctor made for her she fast forwards through a long section before reaching the Doctor's last point. There was no actual script for what David Tennant was saying in this section, as we see in the deleted scenes. Instead he lets loose a babble that covers not only the fact that he has to talk for a minute and a half, but he also tells us about The Housemartins and a gig of theirs he saw in 1990, before wrapping up with a string of random words and sounds.
4. The receptacle for The Doctor's identity was changed from a cricket ball to a pocket-watch, as this was something which could actually be opened.
5. This serial was adapted by scriptwriter Paul Cornell from his 1995 Doctor Who novel, "Human Nature." This marks the first time in Doctor Who history that a novel based upon the series was adapted as an episode. Many changes were made in transferring the novel to the screen. The original book featured the Seventh Doctor and his companion, Benny Sommerfield, and the Doctor's motive for becoming human was to study the human condition, not to flee aliens.
6. John Smith's skill with the cricket ball is reminiscent of that of the Fifth Doctor, best shown in Doctor Who: Black Orchid: Part One (1982)/Doctor Who: Black Orchid: Part Two (1982) and Doctor Who: Four to Doomsday: Part One (1982)/Doctor Who: Four to Doomsday: Part Two (1982)/Doctor Who: Four to Doomsday: Part Three (1982)/Doctor Who: Four to Doomsday: Part Four (1982).
7. The scarecrows were added because Russell T. Davies wanted a traditional monster for the story.
8. The aliens in this episode were intended to have technology that was very organically based and this carried through to the design of their guns. The guns' theoretical design was that there was a creature inside each gun and pulling the trigger resulted in a jab to the creature, who would then scream; this scream is the disintegration beam.
9. In the opening of the episode, The Doctor tells Martha Jones that the Family of Blood is able to follow them even though they are fleeing in the TARDIS because the Family has stolen a Time Agent's Vortex Manipulator. This suggests that the Family have, in the past, encountered one of the five Time Agents aside from Captain Jack Harkness and Captain John Hart, as both are still in possession of theirs.
10. A great deal of the episode was rewritten by Russell T. Davies.
11. Fearing that a straight adaptation of Human Nature would be too old-fashioned for New Who's modern storytelling sensibilities, Paul Cornell struggled mightily with the construction of his scripts. At one point, for instance, the adventure opened with The Doctor already married to Joan Redfern (now the school's nurse rather than a teacher). Russell T. Davies encouraged Cornell to hew more closely to his novel, however. Later, Cornell had the timeline for the episodes stretch over several weeks to provide time for John Smith's courtship of Joan to play out, but it was found that this removed too much intensity from the Family's pursuit of The Doctor.
12. John Smith's birthplace was given as Gallifrey. This planet The Doctor is from. Though in this episode he states it is somewhere in Ireland. He says he was brought up in Nottingham to reflect David Tennant's desire to continue using his English accent.
13. The Aubertides of the novel were creatures whose entire being (including their clothes and possessions) was an extension of their form. Paul Cornell tried to make this work on screen, including giving the little girl (whose last name was initially Wainwright, changed to Cartwright because Doctor Who: Blink (2007) already featured a character with that surname) a sentient, attacking balloon, and having Martha realise that Jenny is an alien when her friend reacts with pain after Martha spills tea on her handbag. Ultimately, however, it was decided that this notion worked better in prose than as television, and so the Aubertides were replaced by the Family of Blood.
14. The setting was shifted forward to the summer of 1914, and then back to the winter of 1913 in order to ensure that viewers not confused as to when the events of the story fell relative to the start of World War I.
15. The cliffhanger originally focused on John Smith being faced with the decision of ordering the schoolboys to open fire on the Family.
16. Part of the plot at one point was Martha's family. At an early stage, the character was intended to actually come from 1914.
17. The Doctor is seen wearing a bow tie in this episode. His next incarnation would go on to wear a bow tie all the time, insisting "Bow ties are cool."
18. Actors Thomas Brodie-Sangster (Tim Latimer) and Harry Lloyd (Baines) both appeared on Game of Thrones (2011) as Jojen Reed and Viserys Targaryen, respectively.
19. The school's name was changed from The Hulton Academy for Boys to The Farringham School for Boys.
20. This episode takes place from 10 November 10 to 11 November 1913.
21. Oliver Redfern was killed in the Battle of Spion Kop in January 1900.
22. The fob watch that figures so prominently in this episode (and through the rest of the third series) was originally seen in the early series one episodes as a knob on the TARDIS control console. It is clearly seen in closeups of Christopher Eccleston's hands as he sets the controls in Doctor Who: The End of the World (2005).

The Family of Blood

1. Scriptwriter Paul Cornell based this serial upon his 1995 Doctor Who novel, "Human Nature", making this two-parter the first time in series history that an original Doctor Who novel was adapted for television.
2. Fourteen days of rain caused difficulty for the production of the episode.
3. Consideration was given to attempting the story entirely without the use of computer effects, but this was ultimately abandoned.
4. The bulk of this episode takes place 5 years to the day in advance of the armistice signed with Germany, ending WWI.
5. Russell T. Davies felt that this two-parter was too dark for the program's audience.
6. David Tennant suffered from voice problems.
7. This episode takes place on 11 November 1913 and in the 2000s.
8. The role of Phillips was offered to Nicholas Briggs but he passed because it was too small.
9. Even in the guise of John Smith, the Doctor cannot bring himself to fire his weapon.

Blink

1. In the disc of the original DVD release of Series 3 with "Blink" in it (disc 4) there is an Easter Egg on page 2 of scene selection of "Blink". It has the Doctor's Easter egg, unedited. To access it, you have to highlight "Blink" in the page and select it. Unlike other bonus scenes and deleted footage, the Easter egg remains "filmized" rather than being rendered on video, in keeping with it supposedly having been filmed in 1969.
2. Steven Moffat revealed that Carey Mulligan was offered the chance to stay on as a companion, but she declined.
3. The Doctor and Martha were purposely not featured in this story so David Tennant and Freema Agyeman could concentrate on the final three stories Doctor Who: Utopia (2007), Doctor Who: The Sound of Drums (2007), and Doctor Who: Last of the Time Lords (2007).
4. This is the first Doctor Who TV story to be directed by a woman, after a 22-year interval. The previous one was Doctor Who: The Mark of the Rani: Part One (1985)/Doctor Who: The Mark of the Rani: Part Two (1985).
5. Steven Moffat claims that the Weeping Angels were inspired by the children's game 'Statues', which he found 'frightening'.
6. Billy Shipton comments that the police box isn't a real one as, "the phone's just a dummy, and the windows are the wrong size." This is a reference to the fact that the TARDIS props over the years have been scaled down versions of the real thing.
7. To create the rigid structure of the angels' dresses, prosthetics supervisors Rob Mayor soaked fabric in fibreglass resin, which was then painted over.
8. Voted Best Story by readers of Doctor Who Magazine in their Season Three Season Survey.
9. One humorous deleted scene would have formed part of the pre-credits teaser. After Sally discovered the message behind the wallpaper, Steven Moffat had requested the sound of cliched horror movie music. This would turn out to be Sally's mobile phone ringtone, and it was actually Kathy calling her friend from a pub.
10. Steven Moffat initially wrote placeholder dialogue in the script for the scene where the Doctor tells Sally that he can hear her in the DVD shop, because he knew the lines that appeared would have to play "double duty later on" and be authentic and fresh both times.
11. To create the effect of the Angels rocking the TARDIS, Carey Mulligan and Finlay Robertson threw themselves around the ship's set. The camera's operator then shook the camera in the opposite direction that Mulligan and Robertson threw themselves.
12. The scene wherein the Doctor talks to Sally via a DVD extra was created by writing a conversation, removing Sally's lines, then having David Tennant record his lines. Steven Moffat felt that this one-way filming made the performance more convincing.
13. The portfolio that Larry keeps the list of "Easter Eggs" in has a Cunard Lines sticker on the back. Cunard Lines is the successor to White Star lines, which owned the "Titanic", possibly anticipating Doctor Who: Voyage of the Damned (2007), which features the spaceship "Titanic".
14. Originally, the producers considered having Michael Obiora play both the young and old version of Billy Shipton. However, it was decided that Obiora in makeup would look too fake, and so Louis Mahoney was cast to play the older version. Initially, Obiora played the role with a London accent. Mahoney, however, has a thick accent. Obiora had to re-dub his lines to match.
15. Due to the show's tight schedule, the episode had only one script meeting.
16. Banto's DVDs included: Breakfast in the Rain, Dance of Days, Civilisation Zero, Angel Smile, Falling Star, One Oak Country, My Best Friend's Boyfriend, Mean Teens, Shooting the Sun. All of these were fake titles created for the episode, complete with DVD cover and poster designs.
17. Billy can be seen in the police station with a patch on his jacket depicting a sparrow, a possible joke on Sally's last name.
18. Kathy was originally named Jenny.
19. In a 2017 interview for the episode's tenth anniversary, Finlay Robertson mentions that he had to change his accent to match Lucy Gaskell's, as their characters Larry and Kathy are siblings.
20. The hologram Doctor uses the term "time capsule" when referring to the Tardis. This has a double meaning: while a "time capsule" could be a time-ship or time-machine (such as the TARDIS), it is more commonly used to mean a cache of items and messages that is meant to be found by future archaeologists. The messages and DVD extra that the Doctor left for Sally to find, and even the TARDIS itself, could be considered such items.
21. The working title for this episode was Sally Sparrow And The Weeping Angels.
22. This episode takes place in 2007, on 5 December 1920, in 1969 and in 2008.
23. David Tennant suffered from voice problems.
24. Michael Obiora and Louis Mahoney played father and son in Sea of Souls: That Old Black Magic: Part 1 (2004).
25. Exploding eggs are mentioned twice - once by the Doctor about his device that has a side effect of boiling eggs and exploding hens, and also by Larry who says that having a complete transcript of the Doctor's DVD extra would "explode the egg forums."
26. A character appears to have a conversation with a video recording of another character. This mirrors a similar scene in Steven Moffat's previous series, Jekyll (2007).
27. A scene cut from the epilogue had Larry revealing that he regularly checks to ensure that the Weeping Angels are still petrified.
28. The renovated shop entrance is painted in shades of blue (like the TARDIS exterior), with round things on the wall (sort of like the proverbial "round things" inside the TARDIS).
29. The plot of this episode was based upon a short story Steven Moffat wrote for the Doctor Who Annual 2006 called What I Did on My Christmas Holidays by Sally Sparrow. The story involves Sally Sparrow (who is a child in the story as opposed to a young woman in the episode) writing her school assignment about being contacted by the Ninth Doctor through photographs and a videotape (like the episode, there is a sequence in which Sally has a conversation with the Doctor through a television) in which he gives her instructions to allow her to return the TARDIS to him (the Weeping Angels aren't present in the story; the Doctor being separated from the TARDIS was due to a "hic-cough"), knowing what to do thanks to an adult Sally (who is a beautiful spy who saves the Doctor's life) giving him the story which details the experience.
30. First appearance of the Weeping Angels
31. At one point, Sally would have been seen to be pregnant at the episode's conclusion, but Steven Moffat decided that it was more effective to delay Sally and Larry's romance until after her meeting with the Doctor.
32. The last lines that (young) Billy Shipton says to Sally Sparrow is that he'd probably phone her tonight. Later that night, old Billy Shipton does in fact phone her.
33. It is possible, and likely, that Billy Shipton married Kathy Nightingale (Wainwright)'s daughter Sally--as Billy tells Sally Sparrow he did marry a Sally (Shipton). Kathy's youngest was Sally, Billy travels back to the 1969, therefore Sally Wainright COULD have married Billy.
34. The chapter ends with the last bit of The Doctor's DVD monologue. There is a close up of his face, he blinks once, and everything goes black for a moment before the end credits.
35. The first draft of the script is very close to the finished episode with the exception of the ending. Instead of taking off by itself, the TARDIS brings Sally and Larry to 1969 where they meet the Doctor and Martha. After returning them to the present, the Doctor reveals that he learned everything from a book called Sally Sparrow and the Weeping Angels. He asks Sally to sign it and she sees that the author's name is Sally Nightingale.
36. Ben Wainwright was born in 1897 and died in 1962.

Utopia

1. Professor Yana's costume was inspired by The First Doctor's outfit.
2. This episode takes place just after the events of the Torchwood series-one finale Torchwood: End of Days (2007). At the end of that episode Captain Jack sees the doctor's severed hand glowing and hears both the sensors in it beeping as well as the sound of the TARDIS, and he runs out to find the Doctor.
3. Just before the start of the opening credits, the scene shifts from showing Jack clinging onto the TARDIS as it flies through the vortex to the Futurekind preparing for a human hunt. According to the DVD commentary, this had to be done, otherwise the opening credits - showing the TARDIS flying through the vortex - would have felt out of place without Jack being seen clinging to the outside. David Tennant and Russell T. Davies joke that they could have re-made the titles with Jack clinging onto the TARDIS and that a 'special edition' may be released in the future with a computer generated Captain Jack attached to the TARDIS.
4. Upon first meeting, the Doctor ask Jack if he's "had work done". John Barrowman, by his own admission, had some minor botox done around his eyes, probably during the year and a half between his appearances on this series.
5. This is the first time in the revived series that The Doctor uses his sonic screwdriver in a vertical fashion, reminiscent of Doctor Who (1963)'s old sonic screwdrivers.
6. Nine year old John Bell from Kilmacolm, Renfrewshire, Scotland, entered a Blue Peter (1958) competition to appear in this Doctor Who story. He was notified by phone by Russell T. Davies that he had beat out 8,000 other competition applicants to appear on the program. Bell went on to a prolific acting career, which included the vaguely Who-like series Outlander (2014).
7. At one point, Jack was to explain that the Doctor's hand had been recovered from a newsagent's roof.
8. The Futurekind originally travelled around on quad bikes. This was abandoned due to safety issues.
9. Chipo Chung said that playing Chantho was "the most fun she'd had in front of the camera".
10. Chipo Chung reappeared in the following season as The Fortune Teller in Doctor Who: Turn Left (2008).
11. The firearm of choice at the end of the universe, some when beyond the year 100 Trillion, is the AK-47.
12. The keyboard Chantho uses is a keyboard for Japanese hiragana.
13. Derek Jacobi (Professor Yana) and David Tennant (The Doctor) have both played the title character in productions of "Hamlet" starring Patrick Stewart as Claudius: Jacobi in Hamlet, Prince of Denmark (1980) and Tennant in Hamlet (2009).
14. John Barrowman performed the stunt where Jack leaps onto the TARDIS on his birthday.
15. This episode takes place in 100,000,000,000,000 A.D.
16. Derek Jacobi played Hamlet in Hamlet, Prince of Denmark (1980) alongside two stars of Doctor Who (1963); Lalla Ward (Romana) who played Ophelia and Geoffrey Beevers (The Master) who played Lucianus.
17. The Futurekind were influenced by the warrior ghosts from Ghosts of Mars (2001).
18. When Professor Yana examines his fob watch, voices of The Master actors Roger Delgado and Anthony Ainley, taken from footage of Doctor Who (1963) are heard.
19. Near the beginning, when the Doctor and Martha find Jack unconscious outside the TARDIS, a brief moment of the theme from Torchwood (2006) (Jack's regular series) is heard.
20. This story features the first canonical appearance of The Master since Doctor Who (1996).
21. Throughout the episode, brief moments of the theme "This is Gallifrey (Our Childhood, Our Home)" play. The music is developed more thoroughly during the following two episodes, in which the Master is a central character; the piece is a leitmotif for the homeworld shared by the two Time Lords.
22. This marks the second time that Derek Jacobi has played the Master, having previously portrayed the character in the BBCi webcast Doctor Who: Scream of the Shalka (2003). David Tennant (The Doctor) had an uncredited role in that production as a caretaker.
23. The Doctor's response to The Master asking him to "use my name" was originally intended to reveal who Yana really was, but the writing team decided it would be a pity to have Derek Jacobi not be able to utter his catchphrase during his brief stint as the character.

The Sound of Drums

1. When The Doctor and The Master are speaking to each other the phone, they really are talking to the other person. Instead of having the lines read to them on the set, David Tennant and John Simm called each other in order to make the scene more authentic.
2. As the Toclafane remove one tenth of the population Noel Clarke's (Mickey Smith) voice can be heard during the alarm calls.
3. The television in Martha's flat was made by Magpie Electricals, the same television-maker featured in Doctor Who: The Idiot's Lantern (2006).
4. Before introducing the Toclafane, The Master offers his wife a Jelly Baby, which was the candy of choice for Fourth Doctor Tom Baker.
5. Martha's suggestion that The Doctor and The Master are brothers - dismissed by The Doctor - was Russell T. Davies response to a popular fan theory he found rather daft.
6. Some of the car action sequences in this episode were filmed by Freema Agyeman herself rather than a stunt double.
7. Mister Saxon (the Master's pseudonym) is an anagram of Master No. Six. Excluding Derek Jacobi's brief moment of glory, John Simm's Master is the sixth incarnation of the character seen on television. However, according to executive producer Russell T. Davies in an interview with the Radio Times, the anagram is merely coincidental. Derek Jacobi played the master twice: once as Professor Yana (aka the master) and in the Doctor Who: Scream of the Shalka (2003) mini-series (voice).
8. As the Toclafane descend on Earth the dance track being played is "Voodoo Child" by Rogue Traders, ironically from the album "Here come the Drums".
9. David Tennant's makeup in which The Doctor is aged 100 years was inspired by William Hartnell.
10. There was originally dialogue between Jack and the Doctor which playfully poked fun at the opening voice-over of Torchwood (2006). This was removed because it was felt to be too metatextual.
11. This episode of Doctor Who features the theme song in a different, lower key than the previous episodes of the revived series.
12. The masters overcoat is the same coat the Twelfth Doctor will wear.
13. This is the first appearance of Jelly Babies in the new series, having last appeared in Doctor Who (1996). However, it is The Master who has them, not The Doctor. They would eventually be seen in the 12th Doctor's possession in Doctor Who: Mummy on the Orient Express (2014).
14. The car chase was originally much more elaborate. It was scaled down due to budget concerns.
15. The Master's speech that opens with "Peoples of the Earth, please attend carefully," parallels a similar pronouncement in Logopolis. His fascination with Teletubbies (1997) is an homage to Doctor Who: The Sea Devils: Episode One (1972), in which he was seen to be watching The Clangers (1969).
16. The Gallifreyan headpiece was an original prop from Doctor Who (1963). At the suggestion of Gary Russell, the young Master's outfit reflected the earlier Time Lord costumes established in The War Games.
17. The Archangel Network was originally named Angel One.
18. Russell T. Davies decided against bringing back The Master's tissue compression eliminator, despite his fondness for it. He decided that he had enough tricks to use against The Doctor.
19. When Saxon addresses the nation, his first words are "Britain, Britain, Britain". Fourth Doctor, Tom Baker used these words often as a narrator for comedy series Little Britain (2003).
20. Russell T. Davies considered using the aliens that became the Toclafane in Doctor Who: Dalek (2005) and Doctor Who: The Satan Pit (2006) when those stories ran into issues with their monsters .
21. The Mysterious Man from Doctor Who: The Lazarus Experiment (2007) was due to make a cameo appearance. But when actor Bertie Carvel was not free, the character became Sinister Woman instead.
22. This is not the first time the Doctor has been subjected to aging. In the last part of The Daleks Masterplan, Doctor Who: Destruction of Time (1966), he survives the aging caused by the activation of the time destructor with no physical effects while others died from aging. However, at the end of Doctor Who: The Leisure Hive: Part Two (1980) he is aged an additional 500 years (to 1,250 years old) resulting in significant physical aging.
23. The Master wears variations of various outfits from different stories. He wears a black single breasted suit, white shirt and black tie (from Doctor Who: Planet of Fire: Part One (1984), albeit without the black leather gloves worn in the original costume). He also wears a black overcoat with red satin lining like The Third Doctor's early outfit and black leather gloves during his airport meeting with President Winters.
24. Many aspects of the episode all revolve around the number four. There are four drum beats; when the Toclafane are first shown, there are four of them; and on each Toclafane there are four spikes on the bottom plate and four spikes on the middle plate.
25. The Toclafane was originally called the Roclafane. This was changed to avoid confusion with the Racnoss from Doctor Who: The Runaway Bride (2006).
26. Vivien Rook was named for journalist Jean Rook.
27. The Doctor, Jack Harkness, and Martha Jones do not appear at all in the trailer for The Sound of Drums.
28. This episode takes place in 2008.
29. First appearance of Lucy Saxon.
30. The website that appears in the episode, "haroldsaxon.co.uk", was a real. To avoid confusion among viewers, the BBC added a legal note at the bottom of the real website, which stated that it was fictional and specifically made for the show. The website was shut down in 2010, but it can still be accessed through web.archive.org.

Last of the Time Lords

1. Despite the original show's limiting of Time Lord regeneration to only 13 lives, this episode, as well as Doctor Who: Utopia (2007) and Doctor Who: The Sound of Drums (2007), presented the Master's 17th life, due to his many schemes to prolong his life past this limit. Also, we learn that it's more an act of will than biology for Time Lords to regenerate. In an episode of The Sarah Jane Adventures, the Doctor jokes that Time Lords can regenerate 502 times, although this has been proved wrong.
2. This episode has two directors, Colin Teague and Graeme Harper. Teague was injured after falling down some stairs and some scenes with Martha in the episode were finished off by Harper.
3. The mysterious woman's hand with the red nails which picks up the ring in the final scene actually belongs to Production Manager Tracie Simpson.
4. The final scene with Jack was written to include dialogue between him and the Doctor which playfully poked fun at the opening voice-over of Torchwood (2006). This was removed because it was felt to be too metatextual.
5. This episode was planned to be broadcast live to the crowds attending Pride London in Trafalgar Square via a giant screen. However, a local curfew after the nearby attempted terrorist bombing the previous day prevented the screening. Freema Agyeman and John Barrowman attended the event.
6. This episode takes place in 2009 and 2008.
7. Leo Jones was also intended to appear in Last Of The Time Lords, welcoming Martha back to Britain and introducing her to Milligan. This had to be changed due to Reggie Yates' scheduling conflicts, which meant that he could only spare one recording day.
8. The is the only regular season finale of the Russell T. Davies era that doesn't feature the Daleks in any capacity (however, they are mentioned in Doctor Who: The Sound of Drums (2007) when The Doctor and The Master discuss the Time War).
9. Last appearances of Clive, Tish and Leo Jones.
10. The first draft script was written in 4 days.
11. Jack in chains complains about being fed "cold mashed swede". The English 'swede' is also called 'Swedish turnip' and 'rutabaga'.
12. Right before Martha decides to not travel with the Doctor anymore, he mentions that they could go back in time and meet Agatha Christie. In Doctor Who: The Unicorn and the Wasp (2008), he did this with Donna.
13. According to Julie Gardner during a panel presentation at the 2008 San Diego Comic Con, John Barrowman wasn't aware of the revelation of Jack being The Face of Boe until fairly late in production.
14. The subtle indications that The Master is physically abusing Lucy Saxon help reinforce her reasons for eventually turning on him in both this episode and in Doctor Who: The End of Time: Part Two (2010).
15. Originally, Downing Street played a much larger role in the story, serving as the location for the last of Martha's decoy chemicals. At this stage, Milligan was in fact a traitor, who was killed after betraying Martha to The Master. Russell T. Davies began to feel that the world of the ravaged Earth deserved greater exploration, however, and concocted the material involving Professor Docherty instead.
16. At the scene where Jack reveals he was called the Face of Boe, several people can be seen in the background taking pictures at the location of the Torchwood lift.
17. In Doctor Who: Last of the Time Lords (2007) Captain Jack Harkness reveals to The Doctor and Martha that he was nicknamed "The Face of Boe", leading The Doctor and Martha to believe that Jack *is* The Face of Boe, the gigantic humanoid head The Doctor, Rose and Martha had encountered on New Earth and Captain Jack grew up in a Earth colony on the Boeshane peninsular. If Captain Jack is indeed The Face of Boe, it's most likely that in the far future, Captain Jack underwent a genetic mutation and mutated into his new incarnation - The Face of Boe.
