The BBC will unite every incarnation of Doctor Who for a one-off Children in Need special in November - with new Time Lord Matt Smith making his debut alongside William Hartnell, Patrick Troughton, Jon Pertwee, Tom Baker, Peter Davison, Colin Baker, Sylvester McCoy, Paul McGann, Christopher Eccleston and David Tennant.
Viewers will see the Time Lords regenerating and emerging one by one from the Tardis, each with their own quirky opening line. David Tennant is the central character in the episode. He’s trying to hunt down some special time travel apparatus.
In case you're wondering just how Hartnell, Pertwee and Troughton will be offering their assistance, a source at the BBC explained: “The actors who are no longer with us, William, Jon and Patrick, will make special cameo appearances, with footage from original shows being flashed up on screen."
