The Christmas Invasion was the 2005Christmas Special ofDoctor Who.

It was the show's first Christmas special since its revival and the first Christmas special starringDavid Tennant asthe Doctor.

It was the first episode ofDoctor Who to premiere onChristmas Day since "The Feast of Steven", the seventh part of 1966 twelve-part serialThe Daleks' Master Plan. However, unlike that episode,The Christmas Invasion was specially commissioned byBBC One to be transmitted outside the programme's normal broadcasting season. It was thus the first in the modern tradition of the "Christmas special", and its sixty-minute running time made it then the longest episode yet produced byBBC Wales.

Narratively, it continued the story ofHarriet Jones, started theTorchwoodstory arc and involvedUNIT in its first major appearance in the new series.

More importantly, it was the first full story to feature theTenth Doctor, played byDavid Tennant. Its initial pre-titles sequence on thePowell Estate was later used to "bookend" the closing scenes ofThe End of Time. Its setting was the first and last place onEarth the Tenth Doctor saw.

To coincide with this release, three short stories were released on theU.N.I.T. website. The first wasAlien Life, part of theUNIT Press Briefings mini-series, which was set directly in the aftermath of theSycorax invasion, where UNIT confirms that aliens exist, and the second and third,Guinevere One andProject Rooftop, part of theOperations Board mini-series, was set during and afterThe Christmas Invasion, respectively, depicting events of the television story from UNIT's perspective.

Synopsis[[edit] |[edit source]]

It'sChristmas Eve and high aboveLondon, the alienSycorax are holding theEarth for ransom. TheTenth Doctor must recover from hisregeneration in time to save thehuman race fromslavery.

Plot[[edit] |[edit source]]

It isChristmasEve onEarth. AsJackie prepares presents andMickey works in thelocal garage, both of them hear the distinctive sound ofthe TARDIS's engines. Rushing out intothe street of thePowell Estate, they see the TARDIS blink into existence above them, ricochet off a few buildings and a post van, then come to a crashing halt. A freshly-regenerated Doctor stumbles out of thepolice box doors, greets the two of them by name and wishes them a merry Christmas before collapsing.Rose follows and, in response to Jackie and Mickey's questions, identifies him as the Doctor.

They bring the Doctor to Jackie's flat and dress him in pyjamas belonging toHoward, Jackie's current beau, who has the habit of keeping pieces of fruit in his pocket for snacks. While Rose discusses the Doctor's change of appearance and the fact he hastwo hearts with Jackie, they do not see a wisp of regeneration energy emerging from the Doctor's mouth, which then floats off into space. Ontelevision,Prime MinisterHarriet Jones and project directorDaniel Llewellyn give a press conference about theGuinevere One space probe, which is about to land onMars. In space, however, the probe is swallowed up by an rock-like spaceship.

That evening, Rose and Mickey goChristmas shopping but are attacked by a group ofmasked Santas armed with lethal musical instruments. Managing to escape when the tuba mortar brings a giant Christmas tree down on the Santas, Rose realises that their attackers are after the Doctor. She and Mickey rush home in ataxi. When they reach the flat, Rose notices anunfamiliar Christmas tree in the sitting room, which Jackie says was delivered to the door. As they deduce that none of them purchased the tree, it suddenly comes to life, whirling around with razor-sharp branches while playing a cheerful rendition of "Jingle Bells" as it tries to slice them all to ribbons. The three retreat to the bedroom with the tree in hot pursuit. As Jackie laments the indignity of being "killed by a Christmas tree", Rose places thesonic screwdriver in the still-comatose Doctor's hand and begs him to help her. Reacting instinctively, the Doctor rises just as the tree bursts through the door and disintegrates it with the screwdriver.

He then strides outside the flat to see who was remotely controlling the tree. From ground level, the Santas stare up at the Doctor, buttransmat away when he threateningly points the sonic screwdriver at them. The Doctor calls them "pilot fish" before collapsing in pain: he is still regenerating, and the energy leaking from him has attracted the "pilot fish"'s attention. He tells them he is having aneural implosion because they woke him up too soon, but Jackie keeps interrupting with a stream of increasingly unhelpful suggestions until the Doctor tells her to shut up. He grips Rose, warning her that something bigger is coming, then loses consciousness again.

PM Harriet Jones during the Sycorax crisis.

The first signal fromGuinevere One arrives on television: a snarling alien face, which is soon broadcast all over the world. Llewellyn is escorted byMajor Blake to theTower of London, which houses an underground facility run byUNIT. There, he meets the Prime Minister and her aide,Alex, who tells him that they're putting out a temporary cover story that students in masks hacked into the television signal. Llewellyn is shaken to realise that extraterrestrial life does indeed exist and that both theBritish government and theUnited Nations are aware of this. A technician,Sally Jacobs, explains that the signal did not come fromMars but 5000 miles above the planet's surface, which means that there is a ship, and it is moving rapidly towards Earth.

As Rose and Mickey use his laptop to access theUNIT website and monitor their readings, the aliens send another signal to Earth. They speak in a language that Rose does not understand; normally, the TARDIS would translate it for her, but it seems that with the Doctor unconscious, that function is not working. Rose examines the bedridden Doctor and finds one of his hearts has stopped, meaning he is too injured to be of use and may die if they attempt to wake him again. Back at UNIT, Blake orders the use of translation software. With no sign of the Doctor, Jones asks Blake aboutTorchwood. She knows that she is not supposed to know about them – not even the United Nations knows — but she wants them to be ready.

The software translates the message: the aliens are called theSycorax, and they areclaiming the planet as their own, demanding surrender or "they" will die. Their word for "human" also appears to be similar to that of "cattle", temporarily baffling UNIT. Jones declines to surrender, replying to the Sycorax with a warning that the planet is armed. As dawn rises over London, the Sycorax enact their first move. With a wave of the leader's hand, blue energy sweeps over a third of the world's population, mesmerising them. The mind-controlled people, Sally Jacobs amongst them, then climb to the highest spots they can find, primarily the roofs of buildings, and stand at the edge, all of them poised to jump.

Checking the UNIT staff's medical records, Llewellyn discovers that all the affected people haveA+ blood. The Sycorax found the sample of A+ blood that was sent with other materials onGuinevere One to identify the human race in case of alien contact, and are somehow using that as a control mechanism. Desperate now, Jones gives an emergency broadcast on television, informing the public that theQueen's Christmas speech has been cancelled as theRoyal Family are "on the roof", and pleads for the Doctor's help if he is out there. Driven to despair by the Doctor's comatose state, Rose breaks down in tears in Jackie's arms.

Harriet Jones aboard the Sycorax's ship

Just then, the shockwave ofthe Sycorax ship entering the atmosphere shatters windows all over the city; the gigantic craft takes position above the Houses of Parliament and an under-reconstruction Big Ben as the frightened population watch. Rose, not knowing what else to do, asks Mickey and Jackie to help her move the Doctor to the safety of the TARDIS. Jackie gathers food and other supplies, including a thermos flask oftea.

The Sycorax teleport Jones, Alex, Blake and Llewellyn up to their ship, where theSycorax leader removes his helmet, revealing a skinless face surrounded by a mantle of bone. His hand hovering over a large glowing button, he demands immediate surrender, or he will order the mind-controlled humans to jump. Llewellyn tries to reason with the Sycorax but is reduced to a pile of bones by the leader'senergy whip, as is Blake when he protests. The choice is left to Jones; half of the world will be sold into slavery or a third will die.

As Rose and Mickey move the Doctor into the TARDIS console room, Jackie goes back to get more supplies. Rose, having apparently given up, broods by the console as Mickey tries to use the scanner to tune into what is happening, but the time machine's advanced technology is detected by the Sycorax. Outside, Jackie watches helplessly as the TARDIS is transmatted up. Not realising that they are aboard the Sycorax ship, Rose steps out of the TARDIS and screams when she sees the aliens. Mickey rushes out after her, dropping the flask of tea, which spills and starts dripping through the grilles at the base of the console next to the Doctor's unconscious form. The Doctor breathes in the subsequent fumes as the tea sparks against various components.

Reunited with Harriet Jones, Rose tries to bluff the Sycorax by citing various things and races she has encountered on her travels, commanding them to leave, but is answered with laughter. The Sycorax leader taunts her attempts to pass off second-hand knowledge as authority... but as he gloats, his alien words start being replaced with English. Rose realises that the TARDIS translation ability is working again, and since the Doctor must be conscious for it to be active, that can mean only one thing: the Doctor is awake. On cue, the Doctor emerges from the TARDIS in Howard's dressing gown, smiling as he says, "Did you miss me?"

Easily deactivating the Sycorax leader's energy whip and breakinghis staff, the Doctor bluntly tells the alien to wait while he gets more important things out of the way; namely, getting reacquainted with his friends. Disappointed at not being "ginger" (red-haired), and somewhat annoyed at Rose's speed in giving up on him, he tells them that all he needed was a "good cup of tea; a superheated infusion of free radicals and tannin. Just the thing for healing the synapses." As the Sycorax leader demands to know who he is, the Doctor blithely strides across the ship's floor, nattering on cheerfully and still working out what his personality is like in this new incarnation. He walks up to the glowing button, discovers that it is powered by A-positive human blood, and quicklydeduces that the Sycorax are usingblood control — they're controlling all the humans with A-positive blood. The Doctor tells the leader that in his unstable state, when he sees a large glowing button he just cannot help himself — and to everyone's shock, he pushes it.

However, instead of sending the possessed crowds on Earth to their deaths, it simply releases them from the Sycorax control. The Doctor explains that blood control is likehypnosis: "you can hypnotise someone to cluck like a chicken or sing likeElvis, but you can't hypnotise them to death. Survival instinct's too strong." The Sycorax were bluffing, and the Doctor called them on it. The leader says that they can still conquer Earth by force with an armada, but the Doctor demands that the humans be left alone (quoting part of "The Circle of Life" fromThe Lion King in the process), challenging the leader to single combat for the planet.

The Doctor goads the leader into the fight by insulting him in his native Sycoraxic. The swordfight ranges from inside the ship to its exterior; in the midst of it, the leader cuts the Doctor's hand off, and it falls to the city below along with his sword. The leader assumes the Doctor will yield as he's been "disarmed". But while his friends are horrified, the Doctor is calm; he notes that he is still within the first fifteen hours of his regeneration cycle. Grinning, he explains that there's enough leftoverenergy after the change to rectify any anomalies or missing bits; and his hand regrows.

Grabbing a new sword, the Doctor notes "This new hand, it's a fightin' hand!" and reengages the leader in battle, ultimately winning the duel. The Doctor pins the leader to the edge of the ship with his sword, commanding him to leave the planet and never return in exchange for sparing his life. As the Sycorax leader appears to yield and the Doctor walks back to celebrate his victory with Rose, he attempts a final attack whilst the Doctor's back is turned. In response, the Doctor calmly bounces asatsuma he finds in Howard's dressing gown offa control button, opening a section of the ship's wing beneath the leader, sending the alien plunging to his death. With a now-grim expression, the Doctor declares he is a man who doesn't give second chances.

The Doctor sends the other Sycorax on their way with a reminder that the planet Earth is defended, and he and his human friends aretransmatted back to London to reunite with Jackie. Jones asks the Doctor if there are more aliens out there, and he confirms that there are thousands; the human race is being noticed more and more and it is something they will have to get used to. As Jones ponders this, visibly troubled, Alex receives a telephone call and quietly informs Jones that Torchwood is ready. Jones appears reluctant, but nevertheless gives the order to fire. The Doctor and his friends watch in shock asfive green beams converge into one over London, and the resulting energy burst destroys the Sycorax ship as it heads into space.

TheTenth Doctor asksAlex, "Don't youthinkshe looks tired?"

The Doctor is furious with Jones, but the Prime Minister tries to justify the use of the weapon (engineered from a crashed spaceship ten years previously) as defending the planet. She tells him how Llewellyn and Blake were mercilessly killed in front of her while the Doctor was asleep, making her realise he cannot be there all the time. The Doctor bitterly retorts he should have warned the Sycorax to run, as the real monsters, the humans, are coming. When Jones asks if she should consider the Doctor another alien enemy, the Doctor warns her that he can bring down her government with just six words, which he whispers into Alex's ear: "Don't you think she looks tired?" Alex gives Jones a startled look, and she demands to know what the Doctor just said, growing frantic in her attempts. Everyone else leaves without a word, and Jones can only apologise quietly.

While the Doctor looks through the TARDIS wardrobe for a new outfit to suit his new incarnation, Jackie, Mickey and Rose serve Christmas dinner in the flat. The Doctor joins them to celebrate, having finally settling on a brown pinstripe suit and a long brown coat. On television, Harriet Jones is seen fending off rumours about her ill-health and a pendingvote of no confidence in the House of Commons. Outside, what looks like snow is falling over London, accompanied by shooting stars, but the Doctor points out that it is, in fact, ash — the remains of the Sycorax spaceship breaking up in the atmosphere. It is a new start for Earth, however; with so many people seeing the Sycorax ship, there is no covering up the existence of aliens this time.

But there are new worlds to see and explore. With a now-trusting Rose by his side and eager to continue their travels, the Doctor looks up into the sky to choose a star for their next destination, assuring her that it will be, in the words ofhis previous incarnation, "fantastic".

Notes[[edit] |[edit source]]

• This is the firstDoctor Who episode clearly labelled as aChristmas special. The seventh episode ofThe Daleks' Master Plan, titled "The Feast of Steven", was written as a Christmas episode and was first broadcast on25 December1965.
• This is the first episode of the 2005 revival ofDoctor Whoto air on a Sunday in the UK.
• David Tennant is credited as "The Doctor", as opposed toChristopher Eccleston who was credited as "Doctor Who". The change in the credit was done at Tennant's request.
  • This occurrence parallelsPeter Davison's request for an identical change in credit when he succeededTom Baker. Like Tennant,Davison's first episode would begin this new billing.
  • This story was effectively the first since 1989'sSurvival to credit the role as "The Doctor".
• The "middle eight" section ofthe theme tune is restored in this episode and is heard for the first time in the revived series.
• Before this episode was broadcast, a tie-in website for theGuinevere One project was created and launched by theBBC. The site includes an introduction by Harriet Jones and an interview with the project director,ProfessorDaniel Llewellyn. The site claims that the probe was developed by theBritish Rocket Group. The organisation's logo partially appears in this episode, in the televised press conference with Professor Llewellyn. The name of the organisation was first mentioned inRemembrance of the Daleks and is a reference to the British Experimental Rocket Group from theQuatermass science fiction serials of the 1950s. David Tennant had previously starred inthe 2005 BBC live remake ofThe Quatermass Experiment as Doctor Gordon Briscoe, and Quatermass' first line to Briscoe was changed by actorJason Flemyng during the broadcast from "Good to have you back, Gordon" to "Good to have you back,Doctor" — Tennant's casting as the Doctor was announced two weeks afterQuatermass went to air, and his castmates would have been aware of the speculation during rehearsals.
• Immediately following this episode,Attack of the Graske, an interactive mini-episode starring David Tennant, was made available on theBBC Red Button.
• Just before the opening credits sequence, Jackie says the line, "Doctor? Doctor who?", continuing a long-running in-joke. Unlike many instances of the joke, however, the line primarily plays as a genuine question, since she has never before met theTenth Doctor and knows nothing ofregeneration.
• The Tenth Doctor speaks with an accent similar to Rose's but unlike theNinth Doctor's Northern one. In a radio interview broadcast on 23 December 2005,David Tennant explained that a line of dialogue had been scripted for this episode which explained that the newly regenerated Doctor had imprinted on Rose's accent, "like a chick hatching from an egg", but the line was deleted from the final episode. This concept would later be added back into thenovelisation.
• The opening shot of this episode, in which the Earth and its moon appear, is reused footage from the opening shot of the episodeRose.
• The song being played by the Santa Claus band which attacks Rose and Mickey is "God Rest Ye Merry, Gentlemen". This song is traditionally associated with the novelA Christmas Carol, written byCharles Dickens, whomthe Doctor and Rose met inThe Unquiet Dead. The song shares its melody with the "Venusian Lullaby" theThird Doctor sang inThe Dæmons andThe Curse of Peladon. The carol can be heard again inThe Next Doctor.
• Another song featured in this episode is "Song for Ten", an original composition byMurray Gold sung byTim Phillips. The next two Christmas specials included an original song on the soundtrack. The Phillips version of the song was very brief, and when the time came to compile a soundtrack album, new lyrics were written for the song (reflecting the events ofDoomsday) and it was recorded byNeil Hannon. "Song for Ten" is the first original song commissioned forDoctor Who since the untitled rap song for theRingmaster heard during the 1988 storyThe Greatest Show in the Galaxy.
• One of the outfits considered by the Doctor in the wardrobe is the costume worn byDavid Tennant in his previous role asCasanova inthe eponymous television serial.
• This marks the first time in the new series that any room in the TARDIS other than the console room is seen on-screen.
  • It is also the only appearance in the firstRussell T Davies era of an area of the TARDIS outside of the console room.
• In a scene filmed for the episode, but deleted before broadcast (though included on the DVD), the Doctor attempts to utter his predecessor's catchphrase, "Fantastic!" but due to his "new teeth" (ref. his comments at the end ofThe Parting of the Ways) finds it initially impossible to do so. This scene was intended to set up the final scene of the episode in which the new Doctor finally utters the word, "Fantastic!"
• The Christmas Invasion can be viewed in its entirety on the BBC America website.
• A signal intrusion incident that occurred inChicago during an airing of theFourth Doctor serialHorror of Fang Rock is referenced by Harriet Jones' aide Alex when he says the official story of the Sycorax appearing via the probe is because of "a mask, some sort of prosthetic. Students hijacking the signal."
• This was the first time a television drama was permitted to film atop the Tower of London.^[2]
• This is the first episode to use music performed by the BBC National Orchestra Of Wales, in contrast to all previous episodes of the revived series which used a computer-created soundtrack.
• Harriet Jones states that the laser that destroyed the Sycorax was taken from technology of a ship that crashed a decade ago, placing the time of the crash in1996.
• Russell T Davies wrote the script with theNinth Doctor in mind, the idea being that the characteristics of the Tenth Doctor would emerge more throughDavid Tennant's portrayal than from scripted lines.
• At one stage, the Sycorax were assisted by an ill-fated civil servant called Sir Aubrey. Having destroyedBig Ben inAliens of London,Russell T Davies considered a scene in which the Sycorax spaceship decimated the newly-rebuilt structure, leading to Sir Aubrey's death beneath the falling rubble. Instead, he decided to demolish a much more modern London landmark:the Gherkin.
• The TARDIS wardrobe contains a Hogwarts uniform.David Tennant was fresh off his appearance asBarty Crouch Jr. inHarry Potter and the Goblet of Fire.
• The prototype of the Sycorax swords was auctioned on eBay to raise funds for theGreat Ormond Street Hospital Children's Charity. It raised £920.51.
• Phil Collinson was fond of Harriet Jones, and he argued against her downbeat fate, which was partly fuelled by the sense of betrayalRussell T Davies felt towardsTony Blair.
• TheGuinevere 1 probe was inspired by theBeagle 2, a British-made spacecraft which landed on the surface ofMars onChristmas Day2003. Sadly, the malfunction of its solar panels prevented theBeagle 2 from establishing contact with its operators on Earth, and the mission was deemed a failure. Davies also remembered the first pictures sent from Mars by theViking 1 lander inJuly1976, and he wanted theGuinevere 1 to transmit something more exciting than the empty, bleak Martian landscape.
• Because theUnited Nations had reacted unfavourably to a UNIT website set up by the BBC to help promoteSeason One,Russell T Davies decided to refer to UNIT by the acronym only.
• Two of the blood-controlled children were named afterRussell T Davies' nephew and niece, Jonathan and Catrin.
• Some consideration was given to moving to high-definition recording, but it was ultimately decided to retain the Digital Betacam format used duringSeries 1.
• During the four months which had elapsed since filming wrapped onBad Wolf/The Parting of the Ways,Billie Piper had adopted a noticeably shorter hairstyle, not realising that the events of the special would occur in its immediate aftermath. As a result, it was decided that she would wear hair extensions for the holiday special.
• Freema Agyeman auditioned for the role of Sally Jacobs, but the production team felt that she was deserving of a more prominent role. She would later playAdeola Oshodi inArmy of Ghosts before landing the role ofMartha Jones.
• Peter Davison visited filming at theBrandon Estate.
• Torrential rain prevented some of the Powell Estate sequences from being completed in London. They were instead taped at Loudoun Square in Cardiff.
• For the interior of the Sycorax ship,Russell T Davies wanted to avoid a traditional metallic spacecraft. As such, these scenes were recorded at Clearwell Caves inGloucestershire.
• Russell T Davies hoped to reprise a shot originally intended forRose, tracking from outside the TARDIS, through the doors and into the console room to reveal the revived Doctor. Unfortunately, these plans had to be abandoned due to the difficulty of transporting the motion-capture equipment into the caves.
• The overall pace of the Gloucestershire work was very slow, hampered by both the technological limitations imposed by the environment andSean Gilder's difficulties with the contact lenses he wore as the Sycorax Leader. This forced an additional day at Clearwell Caves.
• It was originally thought that the swordfight between the Doctor and the Sycorax Leader on the wing of the spaceship would be performed on the roof of a tall building in Cardiff. However,James Hawes could not find a venue which obscured the surrounding conurbation, and so the sequence was instead filmed against an unobstructed view of the sea at the docks in Barry.
• Originally,Russell T Davies had hoped to emphasise the global threat of the Sycorax by including scenes of blood-controlled humans nearthe pyramids and onSydney Harbour Bridge. However, neither shot could be realised convincingly, and they were both dropped.
• A deleted scene saw the Tenth Doctor realising that his predecessor's “Fantastic!” catchphrase no longer suited him.
• The concluding scene initially saw the Doctor and Rose ruminating on how they missedthe Ninth Doctor, but the production team felt that the special should be looking to the future in its closing minutes, rather than reflecting on the past.
• To accompany the scene of the Doctor in the TARDIS wardrobe,Russell T Davies originally wanted to use the1963 version of "The Bells of St Mary's" byBob B Soxx & the Blue Jeans. When the rights proved prohibitively expensive,Murray Gold was instead asked to create an original tune. The result was "Song for Ten".

Ratings[[edit] |[edit source]]

• 9.84 million^[3]

Myths[[edit] |[edit source]]

• Some early reports suggested that the enemy would be theCybermen. Tabloid newspaperThe Sun reported thatShaun Dingwall would return asRose's father,Pete Tyler, and that this episode would be set on an alternativeEarth. However, all of these claims were proven to be incorrect when the episode was broadcast, and appear to refer toRise of the Cybermen/The Age of Steel. Coincidentally, the Cybermen were later announced as the enemies inthe later 2008 Christmas special.
• After the announcement thatChristopher Eccleston would leave after the first series, there were erroneous reports that the regeneration was to take place during the Christmas special, not duringThe Parting of the Ways.(This may have been an intentional red herring in order to maintain at least some element of surprise for the series finale given that the BBC had accidentally blown Russell T Davies' plan for a surprise regeneration.)

Influences[[edit] |[edit source]]

• Besides being the name of the invadingaliens,Sycorax is also the name of thewitch inWilliam Shakespeare's play,The Tempest. In the laterseries 3 episode,The Shakespeare Code, the Doctor accidentally gives Shakespeare the name "Sycorax" when he sees an animal skull which reminds him of one of the aliens.
• The Sycorax, with their curse-like blood control technology and bone-motif costumes, are slightly similar toFaction Paradox, a time-travelling voodoo cult created byLawrence Miles that were recurring villains in theBBCEighth Doctor Adventures novels.
• Harriet Jones's decision to destroy the Sycorax spaceship, despite the fact it was leaving Earth, echoesMargaret Thatcher's decision to sink the Argentinian shipBelgrano in the 1982Falklands War, even though evidence suggests it was actually leaving British waters.
• Guinevere One, the name of the probe that Earth sends toMars, references the myths ofKing Arthur. In those stories, Guinevere was Arthur's Queen Consort. Her name is an old French form of the Welsh name Gwenhwyfar, which can be translated as "white shadow". Her adulterous affair with Arthur's chief knight,Lancelot, and betrayal of her husband led to the downfall of their kingdom. When theSeventh Doctor was recognised asMerlin, Arthur's advisor, he assumed that he would later find himself in this role. (TV:Battlefield)
• The Doctor's sword duel with the Sycorax leader, particularly when his hand is cut off, resembles thelightsaber duel betweenLuke Skywalker andDarth Vader inStar WarsEpisode V: The Empire Strikes Back.
• The Doctor comments that the bathrobe and pyjamasJackie has given him to wear are "veryArthur Dent". In the short storyHave You Seen This Man? on theWho is Doctor Who? website, a certain Arthur Dent mentions that the Doctor had once laid in front of abulldozer in front of Dent'shome, meaning that the reference inThe Christmas Invasion is more this likely referring to this encounter between the characters. Arthur Dent is a character inThe Hitchhiker's Guide to the Galaxy, created by formerDoctor Whoscript editorDouglas Adams. Also, Jackie's line "Anything else he's got two of?" is also spoken by Arthur Dent in the 2005 movie adaptation ofThe Hitchhiker's Guide to the Galaxy, in reference to the two-headedZaphod Beeblebrox.
• When speaking to the Sycorax of the great potentialhumans possess, the Doctor realises he is quoting fromThe Lion King.

Production errors[[edit] |[edit source]]

• When Mickey calls Rose to check out the military broadcast of the Sycorax ship, you can see for a split-second the video player playing the broadcast, revealing that it was not green-screened, but a video playing on the computer.
• Although it has been a very short time since the Doctor regenerated, as Rose passes the door of the TARDIS after the Doctor collapses, her hair is visibly longer. (TV:The Parting of the Ways) This exposes the several month break between the wrapping up of Series 1 in March 2005, and the beginning of filming for Series 2 in July, during which time Billie Piper allowed her hair to grow longer.
• When proclaiming his new form to be "lucky", the Doctor is facing towards the Sycorax ship, but when mentioning being in the first 15 hours of his regenerative cycle, he is facing away from the Sycorax ship. He is facing the ship again when his hand regrows.
• A lot of the shots between the Doctor winning the challenge and giving his warning to the Sycorax horde have inconsistent lighting. One notable example of this is when the Doctor throws the satsuma, the light is on the right side of his face but is then on the left side of the button the fruit hits when it should be on the right. The green screen of the ship exterior is also darkened on the left side, making this error more prominent.
• In one of the Tower of London scenes, the Guinevere 1 Space Probe is incorrectly spelt "Guinivere 1" on a computer screen.
• In the 2017 Series 2Blu-raySteelbook, Phil Collinson, the producer of this episode, is incorrectly credited after the title sequence as "Phil Collision".

(TV:Last of the Time Lords) It bubbled furiously when it sensedthe TARDIS flying off to findJenny. (TV:The Poison Sky,The Doctor's Daughter) After the Doctor used it as a receptacle for regeneration energy, something compelledDonna to touch the hand, enabling it to grow into theMeta-Crisis Tenth Doctor and also turning Donna into theDoctor-Donna, leading them to defeat theNew Dalek Empire and stopDavros'reality bomb.

  • The Mighty Jagrafess [sic] (TV:The Long Game)
  • The Daleks (TV:Dalek,Bad Wolf/The Parting of the Ways)
• Rose attempts to invokeArticle 15 of the Shadow Proclamation. (PROSE:Diamond Dogs) Presumably, she was attempting to recallConvention 15, which the Ninth Doctor had used to approach theNestene Consciousness. (TV:Rose)
• The ramifications of the destruction of the Sycorax vessel, including the impact on a group of female (and presumably related) Sycorax, is explored inCOMIC:The Widow's Curse.
  • It also indicates that the Sycorax Leader's proclamation of "Fadros Pallujikaa" is actually his name.
• The TARDIS is in motion as it materialises, due to the Doctor speeding it up to breakneck speeds in the time vortex. (TV:Born Again) It has materialised and dematerialised in motion before, (TV:Fury From the Deep,The War Games) and would do so again next Christmas. (TV:The Runaway Bride)

• The Doctor previously encountered the Sycorax andblood control in hisseventh incarnation atthe Blood Bank in thefar future. (AUDIO:Harvest of the Sycorax)
• By seeding the downfall of Harriet Jones as Prime Minister, the Tenth Doctor unwittingly triggered a cascade of events that would endanger the universe and end with his demise:
  • The Doctor and future companionMartha Jones arrived atMalcassairo in the year100,000,000,000,000 by accident. They also found thatJack Harkness hitched onto the TARDIS exterior and was dragged through theTime Vortex, trying to reunite with the Doctor after being left behind at theGame Station when he was madeimmortal by theBad Wolf. (TV:The Parting of the Ways,Utopia)
  • The group metProfessor Yana, who Martha noticed had afob watch. After her experience with thechameleon arch, she thought Yana was a benevolentTime Lord that became human, but Yana's true identity belonged to theWar Master, who had fled theTime War. After regenerating, he stole the Doctor's TARDIS and fled the planet, but the Doctor tampered with his TARDIS to trap him on Earth. (TV:Human Nature,Utopia)
  • Jones' removal from power allowedthe Saxon Master to replace her under the identity of Harold Saxon, though he was later removed from power and shot byLucy Saxon for tormenting her. He chose to die rather than regenerate into a new incarnation and live a life of captivity. (TV:The Sound of Drums,Last of the Time Lords)
  • TheDisciples of Saxon, the Master's followers, resurrected him, but Lucy again tried to kill him and managed to damage his new body at the price of her own life. The crippled Master was soon recruited byJoshua Naismith to work on theImmortality Gate for his intellect.

  • The Doctor cut the link holding Gallifrey out of the Time War, which sent the Time Lords back into the battlefield, the Master joining them. However, he left the Immortality Gate's nuclear bolt running. It went into meltdown and the excess radiation would have dumped into the containment booth with Wilf still inside. Trying to operate the booth in any way would also have the same result. In order to rescue Wilf, the Doctor had to enter the booth and expose himself to the radiation, leading to his regeneration. (TV:The End of Time)
• On Christmas Eve 2006, an older version of the Tenth Doctor returned to London on the day that his newly regenerated self was battling the Sycorax above the city. On that occasion, he visited a young patient atSt. Nicholas's Hospital,Daniel Francis Thompson, and helped him awaken from his coma. (PROSE:Deep and Dreamless Sleep)
