Filming for the 50th Anniversary Doctor Who special is well underway at this point and they have just released a poster to tease us with as anticipation builds for the show.

All three doctors appear in the poster, Matt Smith, David Tennant and John Hurt to promote the one off special The Day of the Doctor. Oooh we are excited already! Three different versions have been released all of the same image. The poster features Tennant and Smith back to back and between them is John Hurt striding away from exploding Daleks, a collapsing Tardis and if you look a little closer (it took me awhile to spot it) you can see the words Bad Wolf.

It also looks like Billie Piper will be returning as Rose, Jenna Coleman as Clara and Joanna Page is also set to star in the special but as to who she plays remains to be seen.

You can check out the intriguing poster below. Oh what does it all mean?  Doctor Who The Day of the Doctor airs on 23rd November 2013.
