A new trailer for the forthcoming Doctor Who series has been posted online.
The sneak peek gives an insight into what can be expected from the second half of the show's seventh series after it went on a mid-season break last year. It features a host of classic characters, including Cybermen and a Sontaran sniper, as well new baddies The Spoonheads, who battle The Doctor as he uncovers a secret lurking in WiFi signals.
There's also a cameo from Willow star Warwick Davis, and hints at the origins of The Doctor's new companion Clara, played by Jenna-Louise Coleman, who will have her first full adventure with the Time Lord in the The Bells Of St John, the first episode which can be seen on March 30.
The new sidekick with a mysterious past has appeared in previous episodes of the drama including Asylum Of The Daleks, and the Christmas special The Snowmen. There are eight new episodes of Doctor Who coming in 2013, including the 50th anniversary special which will air on November 23.
