Doctor Who will resume on 30 March with an Easter Special called The Bells of St John, and a new nemesis The Spoonheads. The announcement comes together with a first promotional image for the second half of series seven, also featuring glimpses of a number of other monsters including the Ice Warriors, who were last seen on screen in 1974.
Doctor Who showrunner Steven Moffat has penned the opening London-set episode which will take in some of the capital’s most iconic landmarks, such as The Shard and Westminster Bridge, and sees the Doctor discover that "something sinister is lurking in the Wi-Fi".
The episode will also act as an official introduction to the Doctor’s new companion Clara Oswald, played by Jenna-Louise Coleman.
Clara has appeared twice before in two different guises but this will be the first chance for fans to meet "the Clara that will accompany the Doctor across the series' eight adventures".
Moffat also gave fans a taster of some of the other upcoming series seven episodes, described as "a movie a week".
"It's the 50th year of Doctor Who and look what's going on!" said Moffat. "We're up in the sky and under the sea! We're running round the rings of an alien world and then a haunted house. There's new Cybermen, new Ice Warriors and a never before attempted journey to the centre of the Tardis.
"And in the finale, the Doctor's greatest secret will at last be revealed! If this wasn't already our most exciting year it would be anyway!"
New series seven episodes will feature guest-stars including Celia Imrie, Warwick Davis, Jessica Raine, Dougray Scott and Tamzin Outhwaite, as well as mother and daughter Diana Rigg and Rachael Stirling, appearing together on screen for the first time.
