Doctor Who is well known for its rumours. Hardly a day goes by without someone claiming either Paul McGann is back or The Rani is making a return, and with the 50th Anniversary Special looming, the rumour mill has never been so busy.

But what is fact? What do we actually know about the Doctor Who 50th Anniversary Special. Or, indeed, specials?

What we do know is there will be at least one special, to be screened in 3D on the small screen and in selected cinemas. Now, we should point out to those who automatically hit the “rant” button whenever 3D is mentioned that you will also be able to watch it in 2D. So desist from your hate now, you won’t be forced to watch it in that medium.

We also know that it will be directed by Nick Hurran; the man who so stylistically helmed stories such as Asylum of the Daleks and The Girl Who Waited, amongst others. A popular choice and one I’m sure can take on the mammoth task of a 3D spectacular.
