One of the photos of the three Doctors ominously stood in a row from the inside of the TARDIS shows something metallic stuck in John Hurt’s pocket. An evil sonic screwdriver, perhaps?
It’s fair to suggest that John Hurt’s Doctor may be the villain of this piece from Matt Smith’s reaction to him in the season 7 finale and indeed, another photo released that shows Matt looking rather worried.
Meanwhile, his companion Clara (Jenna Louise Coleman) looks to be in the middle of the action in a photo with Kate Stewart (Jemma Redgrave) who appeared in season 7's The Power of Three.
There’s also a shot of David Tennant manning the old version of the TARDIS (ah, memories) and Matt Smith dangling from the blue box, clinging on with his fingertips.
The only person inexplicably absent is Rose Tyler (Billie Piper). Where are you at Rose?!
