The BBC has revealed its plans to take over TV and radio to mark Doctor Who's 50th anniversary.
Special programmes are planned across the BBC, with the celebrations culminating on November 23rd with the airing of anniversary episode, The Day of the Doctor. This will star Matt Smith, David Tennant, Jenna Coleman, Billie Piper and John Hurt, and will be 75 minutes in length.
On top of this, each BBC channel will be home to unique content, celebrating the wealth of history and talent from the last 50 years.
BBC2 will broadcast a number of new commissions, focusing on telling the story behind the show.
Professor Brian Cox will take an audience of celebrity guests and members of the public on a journey into the universe of the Doctor, from the lecture hall of the Royal Institution of Great Britain. Drawing on the latest theories, as well as 200 years of scientific discoveries and the genius of Einstein, Professor Cox will try to answer the classic questions raised by the Doctor, such as can you really travel in time?
An hour-long special of The Culture Show presents Me, You and Doctor Who, with lifelong fan Matthew Sweet exploring the cultural significance of the BBC's longest running TV drama, arguing that it is one of the most important cultural artefacts of modern Britain.
BBC2 will also air An Adventure in Space and Time, which will tell the story of the genesis of Doctor Who and the many personalities involved.
There will also be programmes across CBBC with 12 Again, where celebrities will share their memories of watching the Time Lord when they were younger.
Blue Peter will launch a new competition giving viewers aged between six and 14 the opportunity to design a new gadget that will become part of the iconic science fiction series. Two live Blue Peter specials will see the presenters joined by aliens and monsters, with viewers challenging Matt Smith to answer their Doctor Who questions.
BBC3 will also host a Doctor Who: Monsters and Villains weekend, counting down to the top Doctor Who monster, along with Doctor Who: The Ultimate Guide for newcomers to the franchise. A further commission will be announced later this year.
Meanwhile, BBC Radio 2 will ask Who Is The Doctor? in a 90-minute documentary featuring newly recorded interviews and exclusive archive material. There will also be The Blagger's Guide To Doctor Who, while Graham Norton will be broadcasting his weekly Radio 2 show live from the Doctor Who Celebration in London on November 23rd.
In addition, Radio 1 will be looking at 'Time Lord Rock' in a 60-minute documentary, and Radio 4 will travel back to 1963 with a three-hour special, Who Made Who?, looking at the world that inspired the TV series.
There will also be special content across the official website and on BBC iPlayer.
