Voyage of the Damned (TV story)

"Information: you are all going to die."

- Heavenly Host

Synopsis
The Doctor finds his TARDIS colliding with a spaceship based on the RMS Titanic during a Christmas party. With the help of a waitress named Astrid, the Doctor must take on the robotic Hosts, as the lives of the Titanic crew and the whole of humanity are in danger.

Plot
The bow of a ship crashes through the wall of the Doctor's TARDIS. The Doctor is momentarily stunned, especially after learning the ship is the Titanic. Pressing some buttons, he repairs the TARDIS walls, pushing the ship out. The TARDIS then materialises aboard the ship. The Doctor soon learns the Titanic is a large luxury spaceship cruiser from the planet Sto, orbiting Earth and finds out the date: Christmas Eve. He decides to stow away to enjoy the party, only confessing his unauthorized status to lively waitress Astrid Peth, who reveals her own desire to travel the stars.

Astrid has found her new job disappointing, as she is not allowed off the ship to visit destination planets. The Doctor cheers her up by sneaking her onto an excursion to London via teleport, along with Morvin and Foon Van Hoff and a small red-skinned alien, Bannakaffalatta. Following alien attacks on London on the previous two Christmases, however, London is deserted apart from the Queen, Nicholas Witchell, and newspaper seller Wilfred Mott. The rest of the population has decided to spend Christmas in the countryside. Ship's historian and guide Mr. Copper gives the excursion party a bizarrely inaccurate explanation of human society, especially Christmas, despite the fact that he claims to be an expert on the planet.

The party returns to the ship because of a power failure in the teleports system. The Doctor attempts to find out what caused it, and discovers that the shields are offline with meteors approaching. The Doctor warns the Captain of the ship, but is forced away from the computer by a Steward, as he is unauthorised to use the system. The Doctor breaks free and tries to warn everyone, but is forcibly taken away from the singer's microphone and taken away from the main party. The Doctor gasps to a guest to look out of the window. He sees the meteors and finds out the shields are off. He tries to tell the staff, but they will not listen, so he follows the Doctor. Also trying to help the Doctor now are Astrid, Foon and Morvin Ban Hoff. Midshipman Frame tries to get the shields back online, but is (non-fatally) shot by the Captain. Three meteors slam into the side of the Starship Titanic.

The Captain is killed in the resulting collision, as are the bulk of the crew and passengers. The Titanic's hull holed in several places, and the TARDIS is left drifting in space before automatically homing in for a landing on Earth. With the teleport system offline and the engines losing power, the Titanic is heading for an extinction-level collision with the Earth. The Doctor makes contact with the injured Midshipman Frame, and leads a small group of survivors in a climb through the shattered vessel to reach him.

Complicating matters are the Host, android servitors that were seen malfunctioning earlier. Now their sole function is to kill the survivors scattered throughout he ship. The Doctor's party is harassed by Host all the way, and the Doctor's sonic screwdriver proves to be useless against them. Bannakaffalatta reveals to Astrid that he is actually a cyborg, something considered shameful in the society on Sto. Bravely, he saves the party from a Host attack by transmitting an electromagnetic pulse from his cybernetic implants, killing himself in the process. The Van Hoffs also die during this attack: Morvin falls from the ledge into the nuclear engines, while Foon commits suicide while pulling a surviving Host down with her. At this, the Doctor makes a grim promise that "no more" will die. The survivors take Bannakaffalatta's EMP unit with them as their only effective weapon against the Host.

The Doctor sends the remaining survivors, including Astrid (who gives him a kiss to follow an old tradition,) on ahead with the EMP unit and the sonic screwdriver, while he attempts to reach Deck 31, the place from which the Host seem to be controlled. Using a security protocol, he convinces the Host to take them to their leader. This turns out to be the cruise line's owner, Max Capricorn, who is hiding in an indestructible "impact chamber" on Deck 31. Capricorn is also revealed to be a cyborg, resembling a small wheeled vehicle. Having been forced out by the company's board of directors (due to their prejudice against cyborgs), he is seeking revenge. The collision of the Titanic into a heavily-populated world will not only break the company, but see the board charged with murder, giving Capricorn his ultimate revenge. Outnumbered by Host and faced with death, the Doctor is saved by Astrid, who has made a short range teleport to his position. She rams Capricorn with a fork-lift truck, and in the struggle both are forced off a precipice and fall into the fiery engine of the ship.

With the Host no longer under Capricorn's control, the Doctor grimly makes his way to the bridge just as the ship plunges into Earth's atmosphere. Working with Frame, he uses the heat from the re-entry to try to re-start the ship's engines, but discovers that they are headed straight for one of the few places in London currently inhabited: Buckingham Palace. Calling through with a security code, he manages to get the Queen out of the building, which the Titanic narrowly misses as the ship pulls up, now back under control. The Queen, in her dressing gown, is heard thanking the Doctor as he pilots the ship back into space.

With the danger over, the Doctor suddenly realises that there might be hope for Astrid after all. A safety feature of the ship's teleport system is that in case of accident, it automatically holds in stasis the molecules of the affected passenger. As she was wearing a teleport bracelet at the time of her death, her pattern might still be stored in its buffers. Despite desperate efforts, only a shadow of Astrid can be generated due to extensive damage to the teleport system, despite the Doctor's claims, "I can fix it, I can do anything!" After a kiss to follow an old tradition, the Doctor watches her dissipate into motes of light that float free into space. This way, she can at least fulfill her dream of exploring the universe, forever.

Sadly, the Doctor teleports back to earth with Mr. Copper, who is no expert on Earth, but a former salesman who lied his way onto the ship to explore the stars. Impressed by his heroism on the Titanic, the Doctor leaves him on the planet to build a new life, with the ship's expenses card, which contains £1,000,000. The Doctor then heads off in the TARDIS, alone.

Story Notes

 * The working title for this story was Starship Titanic. It was changed when it was pointed out that Douglas Adams had created a video game and novel by that title years earlier.
 * Also according to The Writer's Tale, American actor Dennis Hopper was approached about playing Mr. Copper and, later, Max Capricorn, but plans fell through.
 * Astrid Peth was originally named simply "Peth" until Davies gave her a second name.
 * Composer Murray Gold and arranger Ben Foster both cameo as members of the Titanic's band, along with singer Yamit Mamo who performs the original song, "The Stowaway". Mamo also performs "Winter Wonderland". An instrumental version of "Jingle Bells" is also heard when the Doctor first arrives.
 * The theme tune has been revamped for Voyage Of The Damned. "I think I just decided to spruce it up - new drums, new rhythm section, new bass line, new little bit of piano," says Murray Gold.
 * The episode is dedicated to the late Verity Lambert, the very first producer of Doctor Who and a legend in the TV industry. Verity died on 22 November 2007, one day before Doctor Who's 44th anniversary, and (per The Writer's Tale), Davies immediately requested a tribute card be inserted into the episode. The TARDIS sound effect is heard softly in the background as the tribute is shown.
 * Angels seem to be a recurring theme throughout the new series. The Doctor has been referred to as a Lonely Angel, faced The Weeping Angels and made use of the Master's mesmeric communication network, Archangel.
 * The Doctor agrees to let Astrid travel with him, but she dies before she gets the chance to. This also happened to Reinette in The Girl in the Fireplace and Lynda Moss in The Parting of the Ways, although Astrid gets to act more in the traditional vein of companion, placing her in the same category of one-time companion as Grace Holloway and Sara Kingdom.
 * The scene where the Doctor is lifted into the air by Angels was heavily criticized by Catholic audiences.
 * This was Kylie Minogue's first major acting appearance since her diagnosis and survival from breast cancer two years earlier.
 * David Tennant's mother died near the start of production of the episode, forcing the crew to shoot around him during his subsequent absence.
 * A specific special effects shot is repeated several times in the episode: someone falling while looking up towards the camera. This occurs at least four times in the episode: when the steward is sucked into space (although he's technically not falling), and when Foon and Astrid fall to their deaths; a fourth occasion can just be glimpsed when Morvin falls.
 * In his first draft of the episode, Davies had Buckingham Palace destroyed by the Titanic (the Doctor stops the ship from crashing but not before it smashes through the palace). In this version, instead of wishing the Doctor a Happy Christmas, the Queen is heard to curse the Doctor. This same early draft also featured a cameo by Prince Charles.
 * At 71 minutes long, Voyage of the Damned holds the record for the longest 'single episode' of Doctor Who since the series revival and the third longest single episode of all (the second longest episode ever is the 1996 movie, which was 85 minutes long, and the longest was the special The Five Doctors, which was 90 minutes long ).
 * Voyage of the Damned has the distinction of being the only episode of the revived Doctor Who not to be shown by the series' Canadian broadcast network, the CBC. The network skipped the episode when it began showing Series 4 in the fall of 2008 and the season ended on 12 December 2008 with no announcement that the Christmas special would be shown. Perhaps coincidentally, beginning with Voyage of the Damned, the CBC no longer received an on-screen credit for its participation in funding the series, although it continued to do so for the remainder of Series 4. When CBC Bold, a digital cable network run by the CBC, began airing Series 4 in early 2009, Voyage of the Damned was again omitted.
 * Midshipman Frame says meteors are coming yet the meteors do not have tails as is shown, further if they are comets as indicted by the tails the tails should not move with a change in direction as the tail always moves away from the sun regardless of direction of travel.

Ratings

 * Overnight - 12.2 million viewers. (At times the ratings peaked at 13.8 million.)
 * Final ratings - 13.31 million, making this the most-watched Doctor Who story since its 2005 return, and one of the highest in franchise history.

Myths and rumours

 * A lot was made of the fact that Astrid is an anagram of TARDIS. This however, turned out to be a red herring and not at all significant to the story.
 * When publicity photos for this episode were first released, some fans noted the resemblance of the Hosts to the Humanoid Axons, giving rise to the rumours (soon disproven) that the episode featured the Axons.
 * As the producers intended, the cliff hanger leading into this story raised the question as to whether the TARDIS had collided with the real Titanic, which gave rise to fan speculation in the interim as to how this episode would reconcile with previous references to the Doctor's involvement with the ill-fated vessel (DW: Rose, et al).
 * The British tabloid press published reports that Minogue's character was going to be a Cyberwoman; this was disproven once publicity photos of her in Astrid's serving girl outfit were released. (According to The Writer's Tale, the tabloid reports of Kylie-as-Cybermen not only went out before she'd actually been cast in the special, but Davies hadn't even completed writing it yet.
 * The meaning of the lyrics in the original song "The Stowaway" (heard only briefly on screen, but released in full on the Series 3 soundtrack album prior to broadcast) have given rise to some speculation. The general consensus is that they are from Astrid's point of view (reflecting in part their first meeting where the Doctor identifies himself to her as a stowaway, supported by the fact they're sung in a female voice), but comments by production team have been interpreted to suggest they might be from the captain's point of view (implying a same-sex interest, but not coinciding with anything that occurs in the episode - the Doctor and the captain never even meet each other). In either case, it was widely speculated that Rose Tyler is the lost love referenced in the lyrics, with the line "lying with his love that's where he'll be" in particular foreshadowing her later return in Series 4, and the events at the conclusion of DW: The Stolen Earth.
 * Newspaper, The Sun released a report claiming Albert Einstein would be in this episode played by Woody Allen.
 * Minogue was reportedly mistaken for a waitress outside a hotel due to her costume.
 * The nature of Astrid's fate led to rumors that she might reappear in Series 4, particularly in the finale; this did not happen (other than a brief flashback appearance in Journey's End). Ongoing rumors suggest a possible return in one of the 2009 specials; as of March 2009 there has been no indication of this.

Location Filming

 * St John's Street, Cardiff (by the Queen's Arcade Shopping Centre)
 * Close to where the shop dummies went on a rampage in "Rose".
 * Where the evil Father Christmases menaced Rose and Micky in the Christmas market in the first Christmas special.

Discontinuity, Plot Holes, Errors

 * As the Doctor was flying with the Hosts towards the bridge of the Titanic, his hair was going upwards instead of downwards. Likely the effect of gel or hairspray. Strong amounts of ether can support light objects and could likely sustain the flight.
 * The Doctor later explains that they flew him up to the flight deck because with Max dead the Hosts were programmed to obey the next highest figure of authority, The Doctor, who had just been acknowledged as a stowaway and a criminal, there were still members of the Titanic crew around so why take orders from the Doctor He was the only non-Host in the vicinity. Also, the Time Lords were regarded as "the oldest and mightiest race in the universe", hence this may have played a part if the Hosts were able to recognise his species.
 * After the Doctor says, "Take me to your leader", he remarks on how he's always wanted to say that sentence, even though his ninth incarnation said it in Aliens of London Perhaps this means that the Tenth Doctor has always wanted to say it and doesn't count his previous regenerations. It could also fall into the category of "old joke".
 * Although the evacuation of London renders the Doctor's concern moot, the question is left unanswered as to how Bannakaffalatta was expected to remain incognito during the shore party excursion to Earth. It doesn't appear that Mr. Copper expected the evacuation to have taken place, given that he expected the passengers to go shopping upon arrival. Perhaps the teleportation bracelets included perception filters similar to that seen in The Sound of Drums.
 * When the Doctor tries to warn the fellow passengers by grabbing the microphone the singer was using, it is branded Magpie electricals; why would a Sto microphone be branded Magpie Electricals. It could be for the same reason the ship looks like the Titanic in that they wanted everything to be as close to Earths variant as possible and that magpie electronics appeared to be a big brand name in the show and thus would be the brand they decided to style it on. It's also established in dialogue that Slade's tuxedo is "a genuine Earth antique", ergo it came from Earth. That means the microphone likely was obtained during a previous visit.
 * The opening collision between the TARDIS and the ship raises several questions: Why would a space-going vessel have a foghorn? How could a vessel in space expel a life preserver (and why would one even be needed?) And how was the captain of the ship not aware that it had not only collided with another craft, but had briefly embedded itself within it? The foghorn and life preserver make the ship seem authentic, and more realistic like the Titanic itself. Perhaps the vessel is designed to enter the atmosphere of a planet, and thus the foghorn would be used. As for the captain being strangely unaware - only Midshipman Frame knew about the meteors and the Captain was after all under orders to crash the Titanic so maybe he did know about the crash but thought that (if anything) that it would only damage the ship more and make it crash faster. An alternative suggestion is that as the Doctor winds the crank on the control panel he is reversing time as the ship slips out and the hull heals itself and that he then jumps the TARDIS out of the path of the vessel.
 * Rickston Slade is seen using a mobile phone (or something similar) both before and after the crash, why couldn't he have used it to send an SOS, the survivors didn't need to get to the Main Deck at all. They also needed to stop the ship crashing, it may have taken a while for the distress vehicle to reach them. Also, given how Slade is portrayed in the episode, he may have simply forgotten to mention he had a phone.
 * Related to the above, the Doctor is seen using a telephone on the bridge to contact Buckingham Palace. Couldn't Frame have been instructed to "phone down" to Earth to warn them about the danger? As this occurs prior to The Stolen Earth the general population wasn't aware of alien life yet, and who would Frame have called? Contacting Torchwood or UNIT would have probably resulted in the ship being blown out of the sky, an option the Doctor would not have sanctioned.
 * Why was there an England flag in the room where the TARDIS landed? This is once again most likely because the ship is based on the real Earth Titanic. Many things in the ship are designed to follow this pattern (edit - this is completely wrong, as the Titanic was built in Ireland and was owned by an American, so England had nothing to do with her other than when she left Southampton [edit- the former is correct, the latter is wrong. RMS Titanic's port of registry was Liverpool.]) Note also that the "landing party" visits London.
 * The Doctor claims that he is 903 years old. This contradicts Time and the Rani, in which the Doctor's age is given as 953. It also contradicts the 2005 series. In Aliens of London, the Doctor claims to be 900. From a real-life viewpoint, Series 1 to Series 3 is 2 years and adding The Year That Never Was, the Doctor ages 3 years between Series 1 and Voyage of the Damned, making him 903. However, if one is to include the three years the Doctor spends separated from Martha in The Infinite Quest, the Doctor is 906 years old. It is not certain that the time between Aliens of London and Voyage of the Damned was 6 years for the Doctor. Between Aliens of London and The Infinite Quest could have been a period of months or weeks, and so the Doctor could still be 903 following the events of The Infinite Quest. The reasons why the Doctor has apparently trimmed his age have yet to be explained on screen; it's possible he may be counting years differently than humans, or has forgotten his true age, or has chosen not to count the Year That Never Was or the 3 years he was separated from Martha, or he's simply lying about his age, or any number of reasons that have yet to be confirmed. Also, the Doctor could be counting his years in Galifreyan years, which might not be equal to Earth years, or he gives his age in the years of the people he talks to; either way he is probably not using Earth years when he gives his age in this episode.
 * When Mr Copper is talking about Great Britain in the final scene, why doesn't the Doctor correct him that the country is actually called the United Kingdom, especially considering that Mr Copper actually referred to the country as the UK earlier in the episode? The Doctor has previously referred to the United Kingdom as Great Britain and it is probably just a habit.
 * The Doctor explained that the exchange rate from credits to pounds is 50 million to 1 million, respectively. This means that Foon Van Hoff's 5000 credit debt is only 100 pounds, or $147. How is it that they'll never be able to pay off 100 pounds? We don't know the wages for workers in robot mills of Sto. The Van Hoff's could earn only a credit a year, but that would be enough for them to live comfortably enough on.
 * In what way is Cardiff the nearest centre of gravity. It's more than likely that "The Rift" is the reason for the TARDIS to choose Cardiff to land in
 * If Host have the strengh of 10 why does one struggle to strangle Morvin. ''Then the Doctor simply pulls it off. Morvin was a fat man, it probably had a hard time for this reasi=on; i mean, have you ever tried to strangle someone with no neck?

Continuity

 * It is explained in the final scenes of DW: Time Crash that the Titanic collided with the TARDIS because the Doctor left its shields down. Time Crash occurs immediately before the collision, which means the very first shot of the Doctor walking around the TARDIS (before the crash) occurs within moments of the Fifth Doctor's departure (however we do not hear the earlier Doctor's admonition to the Tenth Doctor to "Put your shields up").
 * Reference is made to the two previous Christmas specials, DW: The Christmas Invasion and The Runaway Bride, with brief clips from both shown.
 * The Doctor uses the phrase Allons-y Alonso, which he stated he liked in DW: Army of Ghosts.
 * The Doctor mentions that his tuxedo is unlucky, referring to the fact he wore the same outfit in DW: The Lazarus Experiment and Rise of the Cybermen / The Age of Steel, both of which resulted in life-and-death struggles.
 * The Doctor is known to Queen Elizabeth (she is heard referring to him as Doctor), and utters a code word to evacuate the Palace and the Queen. This is quite a contrast from his relationship with her ancestor in DW: Tooth and Claw.(This is probably because of Captain Jack's influence in Torchwood)
 * There are more than a few references to DW: The Robots of Death, the robots chanting "Kill, Kill, Kill" in monotone and the hand of the robot being stuck in the bridge's door and being subsequently cut off. The Hosts also play a similar subserviant role to the robots in the earlier story.
 * Earth was first referred to as Sol 3 in DW: The Deadly Assassin (and last referred to as in Last of the Time Lords).
 * This episode contains one of the few scenes in the revived series in which the Doctor is actually shown eating (when he helps himself to a buffalo wing).
 * Earth was next referred as a Level 5 planet in DW: Partners in Crime, and in the Sarah Jane Adventures episode "Revenge of the Slitheen"
 * The television on which the Doctor, Astrid and Wilf view the news is clearly branded with a Magpie logo, as a reference to Magpie's telly's in DW: The Idiot's Lantern.
 * In the episode Turn Left, the Titanic crashes down onto Buckingham Palace, which destroys London and floods Southern England with nuclear radiation (and not the entire world as the Doctor fears).

DVD and Other Releases

 * Released in the Series 4 DVD boxset.
 * Released on Region 2 (UK) DVD on 10th March 2008. Unlike most single-disc Region 2 DVD releases from the revived series, this was not a "vanilla" edition (program only, no extras), but included the mini-episode Time Crash, as well as an edition of the cutdown version of Doctor Who Confidential.
