Eighth Doctor Paul McGann has reprised his role as the much-loved Time Lord in a mini-episode that’s part of the show’s 50th anniversary celebrations.
It's quite a turnaround for him as McGann previously claimed that he was not a part of Doctor Who's 50th celebrations, and admitted he was "gutted" not to be involved.
The Night of the Doctor sees McGann play the eighth Doctor on-screen for the first time since 1996 – and in what will be only his second screen appearance as the sci-fi legend.
The short - which runs for a little under seven minutes - finally reveals how this particular incarnation of the Time Lord met his end and also confirms that John Hurt's Doctor follows directly on from McGann's version.
Full of nods to Doctor Who fans, The Night of the Doctor also reintroduces The Sisterhood of Karn from the 1976 storyline called The Brain of Morbius and features references to the eighth Doctor's adventures in Big Finish's series of audio plays.
