The BBC has announced a raft of programmes to mark the 50th anniversary of the first episode of Doctor Who.
A 75-minute special called The Day Of The Doctor will star the soon-to-leave Matt Smith and David Tennant.
Smith said: “Hope you all enjoy. There’s lots more coming your way.”
Other highlights include a BBC Two lecture by Professor Brian Cox on the science behind the hit show and the drama An Adventure In Space and Time, written by Mark Gatiss.
The one-off programme stars David Bradley, of the Harry Potter films, as William Hartnell – who was the first Doctor in 1963.
BBC Four will introduce new audiences to Hartnell, with a re-run of the first ever story. The four episodes are being shown in a restored format, not previously broadcast in the UK.
BBC Two’s flagship arts programme The Culture Show is to present Me, You and Doctor Who, with lifelong fan Matthew Sweet exploring the cultural significance of the BBC’s longest running TV drama.
A 90-minute documentary on BBC Radio 2 will ask “Who Is The Doctor?” – using newly-recorded interviews and exclusive archive material to find an answer – while BBC Three will be home to several commissions.
For those less familiar with the show, Doctor Who: The Ultimate Guide will provide a handy primer.
Danny Cohen, Director BBC Television said: “It’s an astonishing achievement for a drama to reach its 50th anniversary.
“I’d like to thank every person – on both sides of the camera – who has been involved with its creative journey over so many years.”
Smith has already started filming his final scenes as the Doctor, which are due to air in this year’s Christmas episode. His replacement, Scots actor Peter Capaldi, was announced in August.
Steven Moffat, lead writer and executive producer on Doctor Who said: “50 years has turned Doctor Who from a television show into a cultural landmark. Personally I can’t wait to see what it becomes after a hundred.”
