Check out the press release from the BBC:

MATT SMITH, DAVID TENNANT AND JOHN HURT TO FACE OFF AGAINST DALEKS IN 50thANNIVERSARY SPECIAL

The Doctors, Matt Smith, David Tennant and John Hurt will battle the deadly Daleks, the BBC announces today, in the show’s 50th anniversary special.

Returning to BBC One on 23 November the highly anticipated adventure will star: Matt Smith; Jenna Coleman; David Tennant; Billie Piper; John Hurt and Joanna Page. In a surprise twist in the recent series finale it was revealed John Hurt would be playing a Doctor, alongside Smith and Tennant.

The Daleks are the second monster to be announced for the 50th and will join the shape shifting Zygons, which have only appeared in the show once before in 1975. The Daleks were one of the first monsters to terrify audiences in 1963, 50 years ago, cementing their place in British popular culture.

Steven Moffat, lead writer and executive producer, said:

“The Doctor once said that you can judge a man by the quality of his enemies, so it’s fitting that for this very special episode, he should be facing the greatest enemies of all.”

The 50th anniversary episode was shot earlier this year at BBC Cymru Wales’ Roath Lock Studios in Cardiff and across South Wales. Filming also took place in iconic London locations the Tower of London and Trafalgar Square for a huge stunt, which saw Matt Smith dangling from a TARDIS alongside Nelson’s Column.
