The pictures show Matt Smith dangling from a tardis over Trafalgar Square while David Tennant mans a tardis control, although not much else is given away.

BBC One has confirmed that Matt Smith and David Tennant will both be playing The Doctor, but John Hurt’s role is still being kept quiet.

The official picture captions decline to mention if he will play The Doctor like Tennant and Smith, fuelling speculation that he could be the incarnation between the eighth and the ninth Doctor.

Jenna-Louise Coleman and Jemma Redgrave are also pictured, but BBC One has yet to reveal any photos of Billie Piper who is also confirmed to return.
