Aliens of London (TV story)

"Funny way to invade, putting the world on red alert."

- Mickey Smith

Aliens of London was the fourth episode of Season 27, and the first story to introduce the Slitheen. It was first broadcast on 16 April, 2005, and is the first of a two-part story. The concluding episode, World War Three, was broadcast on 23 April.

Synopsis
The Doctor takes Rose back to 21st century London, just in time to witness a spaceship crashing into the River Thames, triggering a worldwide state of alert and the closing off of the city. As the Doctor investigates the survivor of the crash, Rose finds problems closer to home.

Plot
The TARDIS materialises on a street in Rose's council estate. The Doctor has taken Rose back home, some twelve hours after she first left with him, by his estimate. However, when Rose goes to see her mother, Jackie stares at her in shock, as they have in fact been gone for twelve months. In the interim, Rose was declared missing, her mother organised a search campaign with posters and her boyfriend Mickey was suspected of murder. Jackie does not understand why Rose cannot seem to tell her where she has been all this time; she blames the Doctor, accusing him of taking her daughter for immoral purposes and slaps him.

Rose and the Doctor talk on the roof of her tower block, where she expresses her frustration at not being able to tell her mother because she would not understand. Nobody else on Earth knows that there are aliens and spaceships and things… just as a massive cruiser-like spaceship roars overhead, trailing black smoke. The craft zooms through Central London, its wing cutting into the side of the Clock Tower that holds Big Ben, ringing the bell before it finally careens and splashes down into the River Thames. The river is cordoned off by soldiers from the Parachute Regiment, and the Doctor and Rose have to watch the events unfold on the television in Jackie's flat. The world is being put on red alert, divers have apparently recovered an alien body from the wreckage of the craft, but there is still no word from the Prime Minister. The body is placed under military supervision under the command of General Asquith and brought to the nearby Albion Hospital. The general examines the body and asks Dr Sato, the pathologist, whether the creature is a fake. She tells him that X-rays of the skull show wiring she has never seen before &mdash; no one could have made it up.

MP Joseph Green, a large, flatulent man and a minor member of government, is escorted to 10 Downing Street, and is met by Indra Ganesh, a Junior Secretary with the Ministry of Defence. Ganesh tells Green that with the Prime Minister missing and the Cabinet trapped outside London due to the gridlock, Green is now Acting Prime Minister. Ganesh hands Green a red box containing Emergency Protocols to deal with extraterrestrial incidents, and Green is met by Margaret Blaine of MI5 and Oliver Charles, Transport Liaison, both as rotund as Green is. Blaine reports that she escorted the Prime Minister this morning to his car, but according to Charles, the car has disappeared. The three government officials leave Ganesh and enter the Cabinet Rooms. Once inside, they look at each other and start laughing.

The evening settles on Rose's estate, and people are holding alien-welcoming parties. The Doctor leaves Rose's flat, saying that he is not good with people. Rose thinks he is going to investigate the crash, but the Doctor tells her that he is not going to interfere with humanity's first contact with extraterrestrial life. To assure her he is not going to disappear, he gives her a TARDIS key. However, once downstairs, he enters the TARDIS and starts it up. Mickey spots the Doctor from his own flat and rushes down, too late as the TARDIS dematerialises.

The Doctor lands the TARDIS in a storage cupboard in Albion Hospital, and opens the door only to run into a group of soldiers, who level their rifles at him. At that moment, they hear a scream, and the Doctor immediately takes charge, barking out orders to lock down the perimeter. The Doctor finds Dr Sato cowering in the corner of an operating room. The supposedly dead alien had come back to life. The Doctor spots the alien, which looks like a pig in a spacesuit, and the creature flees in terror, only to be shot by a soldier. He angrily berates the soldier for killing the creature, protesting that it was only frightened. Examining the body with Dr Sato, the Doctor tells her that it is a real pig, its brain augmented by alien technology. Something else alien wanted to fake an alien crash landing, but for what reason? By the time Dr Sato asks the question, the Doctor is gone, to the echo of a dematerialising TARDIS.

Harriet Jones, a backbench MP, approaches Green, Charles and Blaine, wanting a report to be placed on the next Cabinet agenda, but is brushed off. She enters the empty Cabinet Rooms and opens the Emergency Protocols box to place her report there, but is intrigued enough to start reading. Later, she hears General Asquith complaining to Green, Blaine and Charles about their inaction, and hides in a side room. In the Cabinet Rooms, the three government officials seem to find Asquith's complaints amusing, and they all start to break wind, laughing. When Asquith threatens to relieve Green of his role as Acting Prime Minister and place the country under martial law, the three unzip the tops of their heads, a bright blue light shining through. As Harriet watches terrified through a crack in the door, General Asquith screams.

Meanwhile, Mickey confronts Rose about where she has been with the Doctor, and smugly tells her about the TARDIS disappearing, telling Rose that the Doctor has abandoned her. When Mickey, Jackie and Rose go to where the TARDIS was formerly parked, Rose's key starts to glow, followed by the TARDIS materialising before their eyes. Rose proceeds inside with Mickey, but Jackie is too overwhelmed by what she has seen, and exits the ship to run back to her flat. The Doctor confesses that he suspected the crash was a fake &mdash; it was too perfect a set-up. Mickey notes that it is an odd way to invade a planet by putting it on red alert. Mickey (whom the Doctor insists on calling "Ricky") and the Doctor exchange barbs, but the Doctor has more important things to do. While Mickey and Rose catch up, the Doctor modifies the TARDIS scanner to track the spacecraft back twelve hours before the crash and discovers that it was launched from Earth. Whoever these aliens are, they have been here for a while.

Jackie sees a news report calling for anyone who has seen any evidence of the existence of aliens and calls the Emergency Alien Hotline to report that she has seen one &mdash; the Doctor, in a blue box he calls the TARDIS. This combination of key words triggers a Code 9 alert, and Ganesh rushes to tell General Asquith. Inside the Cabinet Office, the alien that was Oliver Charles puts on the general's skin, while Blaine remarks that they have do something about the "gas exchange" that is causing their flatulence. Ganesh tells Asquith about that the Doctor has been spotted, and when Blaine asks who this "doctor" is; Ganesh explains that the Doctor is the expert on aliens, one they desperately need. In the meantime, other alien experts from around the world, including the United Nations Intelligence Taskforce, are being summoned to Downing Street.



When the Doctor, Rose and Mickey exit the TARDIS, they are immediately surrounded by armed soldiers, vehicles and a helicopter. Mickey runs away and escapes, but the Doctor and Rose are put into a limousine and escorted to 10 Downing Street. The police escort Jackie up to her flat and a full-figured, gassy police inspector assures Jackie that Rose is in a position to help her country, and asks Jackie how she made contact with the Doctor.

At Downing Street, Ganesh, who has gathered all of the experts together, meets the Doctor and Rose. Ganesh tells them that their ID cards must be worn at all times, and ushers them into a room. Rose, however, is not cleared and thus not allowed in. Harriet Jones, who managed to sneak out of the Cabinet Rooms unseen, comes along at this point and offers to take care of Rose. She takes Rose to the Rooms and shows her Oliver Charles's empty skin. When they search the room for alien technology, they find the body of the Prime Minister stuffed in a cupboard. Ganesh enters at this point, and is aghast when he sees the Prime Minister's body.

At the briefing headed by Asquith and Green, the Doctor reads the reports and notices that three days before, a satellite picked up a blip of radiation under the North Sea. However, before anyone could investigate, the crash happened. The Doctor realises, however, that the reason someone would fake an alien invasion is so they can gather those who have experience and knowledge in fighting off aliens together in one place. The crash is not a diversion &mdash; it's a trap.

In the Cabinet Rooms, Blaine enters, closing the door behind her. Ganesh states that it's impossible for the Prime Minister to be dead, as he was driven away from Downing Street that morning. Blaine smugly explains that the only reason that he thinks that is because she told him that earlier, and begins to unzip her head before a horrified Ganesh, Rose and Harriet. In Jackie's flat, the police inspector does the same, and in the briefing room so does General Asquith. The enormous, greenish aliens wriggle out of their skins, the one inhabiting Blaine attacking Ganesh and the one that used to be the inspector cornering Jackie in her kitchen. In the briefing room, the unmasked Asquith identifies himself and his cohorts as the Slitheen. With that introduction, Green activates a hand-held device that sends a deadly dose of electricity jolting through the experts' ID cards, including the Doctor's…

Story Notes

 * This episode had the working title "Aliens of London Part One" ("World War Three" being "Part Two").
 * The episode ends on a cliffhanger, the first since episode two of Survival. The story continues in World War Three. This is also the first occasion since Invasion of the Dinosaurs in which the first episode of a serial does not share its title with the second.
 * A poster announcing Rose's disappearance states that she has not been seen since 6 March, 2005. However, the BBC-produced "official" UNIT website indicates that the climactic events of Rose happened on 26 March. The same site also dates this episode at either 26 May or 28 June 2006. If the June date is accepted, Boom Town (and also The Parting of the Ways) would have to take place in late December 2006 — the same week as The Christmas Invasion (dated to 2006 by the Guinevere One website). On the other hand, if only on-screen evidence is accepted, Aliens of London would take place in March 2006, Boom Town in September, and The Parting of the Ways later in the autumn or early winter.
 * The official police poster is the first reference to the Powell Estate on the television series. Rose is described as, "19 years old, 5 feet 4 inches in height, slim build with shoulder-length blonde hair." The photograph used is one of Billie Piper herself, rather than one of Piper playing Rose. Several other, home-made posters are seen on Jackie's table, including one with a banner headline saying "WHERE IS ROSE?".
 * When the Doctor complains of being slapped by Rose's mother, Rose laughingly remarks, "You're so gay!" This remark has caused some controversy in fan circles, some seeing it as an anti-homosexual slur. Davies, who is gay, wrote in an e-mail response that it was the way people talked, and claimed that he was trying to provoke discussion by using the phrase.
 * A running joke involving the Slitheens suffering from flatulence while in their human disguises was also slightly controversial in fan circles, with some critics disapproving of the style of humour. It did, however, give rise to one of the most quoted lines uttered by the Doctor during the season: "Would you mind not farting while I'm trying to save the world?"
 * The scene where the pig-like "alien" is breaking thought the metal door with Dr Sato watching in shock is reminiscent of an almost identical moment in the 1996 Doctor Who television movie, in which the newly-regenerated Eighth Doctor breaks through the metal door of the morgue, terrifying a hospital worker.
 * The production team had intended to suggest that the murdered Prime Minister in this episode was current real-life incumbent Tony Blair. On the DVD commentary for the following episode, producer Phil Collinson explained that they had hired an actor to play the dead body on the understanding that the man was a Tony Blair lookalike. When the resemblance proved disappointing, they decided to avoid showing the body clearly. The suggestion that the body is Blair's remains in Harriet's line "I'm hardly one of the babes", a reference to the large number of female Labour Party MPs who entered the House of Commons in Labour's 1997 general election victory, who were dubbed "Blair's Babes" by the British media. That Tony Blair was elected in the Doctor Who universe was confirmed in Rise of the Cybermen.
 * The armoured personnel carrier seen outside Number 10 is a Saxon, possibly foreshadowing future events.

Myths
to be added

Location Filming

 * The Cardiff Royal Infirmary provided the setting for the fictional London Albion Hospital. The interior scenes at "10 Downing Street" were shot at Hensol Castle in Wales.
 * The entrance to the Prime Minister's residence was a redress of a similar-looking door in Central London.

Discontinuity, Plot Holes, Errors

 * When the ship crashes into the clock tower, both the numbers on the clock face and the text beneath are backwards. According to the DVD commentary, director Keith Boak altered his shots of the crash sequence but this was not related to the visual effects team, who had prepared according to the storyboarded version. As a result, the sequence was electronically flipped to make it conform to the spaceship's final descent pattern.
 * The clock also appears to keep working after the incident: the time reads roughly 10:55 when the spaceship strikes it, but reads roughly 6:10 when the clock is later seen on a news broadcast. (The shot is flipped)
 * For the first time the Doctor states that he is 900 years old, contradicting the last on-screen reference to his age, 953, in Time and the Rani. Although initially rationalized as the Doctor lying about his age, or "rounding down" or perhaps only counting his years of travelling in the TARDIS, the later Voyage of the Damned muddies the waters by having the Doctor give an exact number - 903 - which tallies with the number of seasons/years since this episode. Other suggested rationales are that the Doctor is counting time differently than done on Earth, or that for some reason as yet unchronicled (perhaps due to the Time War) he has forgotten some years of his life.
 * Dr. Sato(Tosh) seems to be reluctant about the concept of aliens, and scared of the "Pig". However, by this point, she is supposedly already working for Torchwood, therefore something like that should be a common occurrence for her.

Continuity

 * Dr. Sato reappears as Toshiko Sato in  Torchwood.
 * UNIT makes its first appearance on television since Battlefield.
 * Mickey notes that he found out on the Internet that the Doctor had worked before for UNIT, among other things. A notation at http://www.whoisdoctorwho.co.uk/ implies that Mickey is the one who has been updating Clive Finch's website since the latter's death in Rose.
 * A boy spray paints the words "BAD WOLF" on the side of the TARDIS while it is parked on the council estate, echoing the mentions of the "Bad Wolf" in previous episodes. According to Russell T. Davies in a 2008 episode of Doctor Who Confidential, it was this scene that inspired him to place Bad Wolf throughout the season.
 * The TARDIS was previously defaced with chalk scribblings in The Time Warrior and The Leisure Hive, graffiti in Paradise Towers and was painted pink in The Happiness Patrol.
 * The Doctor revisits Albion Hospital in 1941 during The Empty Child and The Doctor Dances.
 * Although not clearly seen on screen, one of the UNIT officers killed by the Slitheen at the end is wearing the name tag "Frost" (the tag is seen more clearly in publicity stills). This may have been a reference to the Doctor Who Magazine comic strip character Muriel Frost.
 * In Love & Monsters the crash sequences (and the events that follow) are seen from an entirely different point of view.
 * The TARDIS key began as an ordinary-looking Yale key, then changed during the Third Doctor's last season into a more alien looking one, which was also used for the first two seasons of the Fourth Doctor's tenure. It then reverted back to the Yale key for the rest of the run of the original series. The alien key made one last appearance in the Doctor Who television movie. It has now returned to looking like an ordinary key, except that it starts to glow when the TARDIS is arriving.
 * The Doctor tells Rose he is 900 years old, however in Time and the Rani he was 953, in Set Piece he was 1000 and in Vampire Science he was 1,012, the Doctor spend 100 years on Earth (The Burning to Escape Velocity) which makes him at least 1,112 (this isn't counting all the intervening time during adventures either).
 * The Doctor offers Mickey a chance to travel with him, which he declines; in School Reunion Mickey invites himself to travel.
 * Beginning with this episode, most "modern day" Earth stories are said to take place approximately one year after the year in which they were broadcast; i.e. this episode and its second chapter take place in 2006, but were first broadcast in 2005.

DVD and Other Releases

 * Aliens of London together with World War Three and Dalek were the first released on the Universal Media Disc format for the PlayStation Portable.
