It's called Day of the Doctor, and it's showing on the 23rd November 2013
The feature length episode title was officially revealed as The Day of the Doctor, which frankly doesn't give much away.
David Tennant and Billie Piper
Former Doctor David Tennant will reunite with former companion and unrequited love Rose (Billie Piper) for the special. They will team up with current Doctor and companion Matt Smith and Jenna Colman. The two Docs apparently love working with each other, proving that the Tardis is big enough for the both of them.
Baddies: Daleks and the Zygons
Come on, the Daleks were never going to miss the Doctor's big day, were they? The tin-pot dictators will return, along with an enemy we've hardly glimpsed since their first appearance almost 40 years ago: the creepy shape-shifting Zygons.
Kate Stewart (Jemma Redgrave) – daughter of the legendary Brigadier Alistair Lethbridge-Stewart and head of scientific research at the United Nations Intelligence Taskforce – will be returning to fight alongside the Doctor. Fans are hoping that means a rematch between the Zygons and UNIT, who last tangled in 1975's Terror of the Zygons.
Who is John Hurt?
Well, John Hurt is Who. As revealed at the end of the last series, John Hurt plays a previously unknown version of the Doctor. According to costume designer Howard Burden, he is a 'dark' Doctor who fits in between Paul McGann (who starred in the 1990s TV movie) and Christopher Eccleston. He said: “There was a gap between Paul McGann playing the Doctor and Christopher Eccleston, when we didn’t see a regeneration, and John Hurt will fit into that gap. He is a past Doctor, not a future Doctor.”
