Lets face it, anybody with an absolute doctor who craze in their mind is waiting for the 50th, looking at the clock like I am, just sat there, waiting. But of course, we do know that John Hurt will definitely be included in it introduced as 'The Doctor' but what doctor is he, surely he must be the 9th? David Bradley is confirmed to be portraying the first doctor in the special spin-off that Steven Moffat has confirmed is "Well over an hour" perhaps 90 minutes or so? The Daleks also make a spectacular re-appearance along with our favourite time-lord, The Doctor. But there's two of them! Matt Smith returns for one of his last episodes and the well-loved memorable David Tennant also returns along with Billie Piper, who plays Rose Tyler. But is Tennant the 10th or is he the Duplicate Doctor from Doomsday? We're not quite sure. Ether way, it looks highly likely, as we all really knew anyway, that this will be an episode based on the Time War. The classic horrors, the Zygons will also return with a slightly tweaked costume, but like the Ice Warriors were, they haven't changed the costume very much at all.
