Time Crash (TV story)

Synopsis
The Tenth Doctor accidentally pilots his TARDIS into the path of the Fifth Doctor's TARDIS--which threatens to annhilate an area of space the size of Belgium!

Plot
This story follows on from Last of the Time Lords: the Tenth Doctor has just said goodbye to Martha, and is attempting to take off when the TARDIS suddenly goes haywire.

And someone else is in the TARDIS: the Fifth Doctor. The Tenth Doctor realises straight away this is his past incarnation and is soon reminiscing about his adventures as the Fifth Doctor, much to the latter's confusion. The Fifth Doctor decides that the strange skinny bloke in his TARDIS is an obsessive fan of his--possibly affiliated with LINDA--and the Tenth, to his own bewilderment, can't convince his past self otherwise. Meanwhile, the collision of the TARDIS with its past self threatens to tear a hole in the universe. The Fifth Doctor despairs of finding a solution in time, but the Tenth purposefully--if maniacally--manipulates the TARDIS controls and averts the disaster.

Stunned by the unexpected solution, the Fifth Doctor realizes that the other man is in fact his future self. The Tenth Doctor bids a warm farewell to his past self; and, with a final warning to his future self to restore the TARDIS shields, the Fifth Doctor rejoins his own timeline.

But suddenly it's too late to put up the shields... the Titanic has plowed through the wall of the TARDIS.

Story notes
This is the first official episode of Doctor Who written by Steven Moffat that doesn't use his theme of highlighting childhood fears.
 * This is the third filmed contribution by the new series production team to Children in Need. In 2005, they had offered the Children in Need Special (aka 'Pudsey Cutaway'). In 2006 they provided a live concert of music during the traditional Children in Need charity time period, and subsequently offered it to home viewers prior to the original broadcast of The Runaway Bride.
 * After it was cancelled, the original series was briefly revived by the inaugural Doctor Who filmed entertainment made especially for Children in Need, entitled Dimensions in Time. In 1983, The Five Doctors was also broadcast as a part of, though not made especially for, the Children in Need charity drive.
 * This story marks the first appearance of a Doctor from the original series appearing in the new series, although recognizable drawings of original series Doctors can be seen in Human Nature.
 * This story is directed by Graeme Harper who also directed Peter Davison's last story (DW: The Caves of Androzani).
 * Steven Moffat (writer) also wrote the Comic Relief story, The Curse of Fatal Death.
 * The special was introduced by Terry Wogan and John Barrowman.
 * Peter Davison's name appears in the credits, the first time (discounting the 1996 TV movie) that an original series Doctor has had his name at the start of an episode.
 * The Fifth Doctor remembers how to save the TARDIS when he is the Tenth Doctor because, as the Fifth, he saw what the Tenth did. This is a reference to time going in a straight line, which makes sense, but was not discussed in The Three Doctors or The Five Doctors.
 * This episode marked the final use of the 2005 arrangement of the "Doctor Who theme" by Murray Gold; a new arrangement by Gold would be introduced in the next proper episode, Voyage of the Damned.

Discontinuity, Plot Holes, Errors

 * If the Tenth Doctor recalls this meeting from when he was the Fifth Doctor, then why was the Fifth Doctor so worried about his regeneration in The Caves of Androzani? (Perhaps in the heat of his impending "death" the Fifth Doctor simply forgot about his future encounter or perhaps time was in flux.)


 * If the Tenth Doctor tells the Fifth Doctor about meeting the Master in that incarnation then he would have known that he wasn't the last of the Time Lords (although this may partially explain the Doctor's extreme reaction to the news that Professor Yana has a Chameleon Arch fobwatch). Possibly, because The Doctor met the Master several times after his Fifth incarnation, he assumed that the Tenth meant one of those other encounters (such as the TV Movie).


 * The Tenth Doctor was at least as much confused meeting himself as the Fifth Doctor and he did not expect the Fifth Doctor thinking he is a fan (Although he should have remembered it).

It might be that the Fifth Doctor, being aware of the problems that paradox may cause, locked these memories in the back of his mind, and remembered at the moment he heard the Cloister Bell.


 * How did the fifth doctor know about LINDA when they where from 2007? The Doctor could easily have visited 2007 at anypoint in his lives.


 * Throughout the story, the Doctor's hand-in-a-jar is located to the right of the console (as seen by viewers), but with the glass turned away from the camera (the illuminated interior can barely be glimpsed. It is in this position as Ten says goodbye to Five. Immediately after, the crash into Titanic occurs, and the hand-in-a-jar is suddenly positioned at the same spot on the floor, but with the glass facing the camera.

Continuity

 * This is the first on screen TV appearance of the Fifth Doctor since Dimensions in Time (and the first 'official' on screen appearance since DW: The Caves of Androzani).
 * The Fifth Doctor previously met the first three Doctors (First Doctor, Second Doctor, Third Doctor) in The Five Doctors.
 * The Fifth Doctor has also met the Sixth and Seventh Doctors in BFA: The Sirens of Time.
 * The Fifth Doctor has also encountered the Seventh Doctor in MA: Cold Fusion which (implicitly) involves the later Doctor remembering having experienced the events as his earlier self, as in this story.
 * The Fifth Doctor also encountered the Eighth Doctor in EDA: The Eight Doctors.
 * The Titanic was seen crashing into the TARDIS at the end of Last of the Time Lords. This story occurs inbetween those final scenes.
 * LINDA last appeared in Love & Monsters.
 * The reference to "Time Lords in funny hats" is to DW: Arc of Infinity.
 * Fifth Doctor identified new series' TARDIS console room's as a desktop theme named "Coral". Also says it to be worse than "leopard skin".
 * This is the first multi Doctor story to account for the aging of the actor returning to play a previous Doctor, by explaining it as a byproduct of meeting himself; this covers off the aging of the Doctors in The Five Doctors but not The Two Doctors as the Second Doctor (not to mention Jamie McCrimmon) appear considerably older long before they encounter the Doctor.
 * According to writer (later executive producer-designate) Steven Moffat, in an interview with Doctor Who Magazine #389, the events of Time Crash are considered canonical.

DVD and other releases

 * It was released alongside Voyage of the Damned.
 * It will be released on the Series 4 boxset DVD in November 2008.
