BBC unveil DOCTOR WHO's 50th anniversary celebrations

The news leaked earlier than scheduled yesterday evening, but the BBC have officially released information about the programming that's been commissioned to celebrate the half centenary of their iconic sci-fi drama Doctor Who.

• Naturally, people are most excited for the 75-minute special that will bring Matt Smith and David Tennant's incarnations of The Doctor face-to-face in the TARDISm, joined by nu-Who's first companion Billie Piper. They'll be joined by guest-star John Hurt (Alien, The Elephant Man), as a previously unknown 'dark version' of The Doctor, with probable links to the events of the infamous Time War. The episode's title is "The Day of The Doctor" and has been filmed in 3D. It will premiere on the date of the show's 1963 premiere, 23 November, in the UK, US and some other territories. Some cinemas around the world will also be showing it simultaneously in the 3D format. To start the hype, the BBC also released the above poster, which includes an intriguing glimpse of a sign with 'BAD WOLF' scrawled across it. Let the theories commence...

• In addition to that jewel in the crown, there's also a 90-minute biopic of William Hartnell, who played the First Doctor in 1963, entitled An Adventure in Space & Time. David Bradley (Harry Potter, Game of Thrones) has taken on the role, in a part written by Mark Gatiss (Doctor Who, Sherlock).

• BBC2 will be showing a light-hearted lecture about the science of Doctor Who, presented by Professor Brian Cox; while there's an hour-long documentary about the show's impact planned as part of The Culture Show.

• BBC Three have a countdown of the best Doctor Who adversaries in Doctor Who: Monsters and Villains Weekend, together with a Doctor Who: The Ultimate Guide special using archival footage from the series.

• BBC Four will be airing repeats of classic Who episodes, including the first ever four-part story, "An Unearthly Child", in a newly-restored format.

• CBBC, BBC Radio 2, BBC Radio 4 Extra and the BBC iPlayer will also have programming available tied into the Doctor Who anniversary.

So what do you make of all that? Is that enough to satiate you, or are you disappointed the BBC aren't doing more? What more could they possibly do, as this equals approximately 20 hours?
