Untitled (Tonight's the Night)

Tonight's the Night was a BBC talent series hosted by John Barrowman which aired in the spring of 2009. In a promotion connected with the series, a contest winner was given a chance to play a villain in a specially written Doctor Who scene featuring Jack Harkness and a surprise guest.

The mini-episode itself carries no on-screen title.

Plot
Jack Harkness enters the Doctor's TARDIS and discovers a blue-headed alien who claims to be a regenerated Doctor. The alien gives the game away when Jack notices that he's armed, something the real Doctor would never be. The alien identifies himself as Sao Til, a literal arms dealer who trades in limbs. Jack draws his gun and the two enter into a Mexican standoff before ... David Tennant enters the TARDIS set and asks John what he's doing. John introduces Tim Ingram of Stoke-on-Trent, who is pretending to be Sao Til. David chides John for being in "my TARDIS" and exits the set. After a moment of giddiness at having seen David Tennant, John and Tim resume their characters and pretend to shoot at each other as they run around the TARDIS set.

Story Notes

 * The skit has no opening or closing credits, and is untitled.
 * Running just over 3 minutes in length, this is the shortest televised Doctor Who story of all time.
 * Also, as Tennant does not appear as The Doctor in this skit, it is the first Doctor Who story since Mission to the Unknown in which the character does not appear, and it is the first and only time a televised story has featured the TARDIS, but no Doctor.
 * A Doctor Who Confidential-style behind-the-scenes look at the making of the skit followed its broadcast, and revealed that Tennant's involvement in the skit was kept a surprise from Ingram until just before filming.
 * This is the first time a Doctor Who skit has been written around a contest winner since A Fix with Sontarans in the 1980s.

Myths and rumours

 * When first announced it was thought the skit would be a potentially canonical mini-episode along the lines of Music of the Spheres and Time Crash, but this turned out not to be the case.

Continuity

 * Barrowman and Ingram break character and Tennant appears as himself, and we see the equipment surrounding the TARDIS set at Upper Boat Studios. This renders the story completely non-canonical and thus it doesn't fit into any timeframe of the series.

DVD, Video and Other Releases

 * No DVD release of this skit has been announced as of June 2009, nor has a DVD release of the Tonight's the Night series itself been announced.
