Doctor Who: Cold War Teasers!

Doctor Who veteran Mark Gatiss returns to pen his latest - and we think his best - episode for the BBC sci-fi drama. But he's not the only returnee - a threat from the Doctor's past is about to resurface... the terrifying Ice Warriors!

Trapped with one of the creatures aboard a Russian submarine at the height of the Cold War, the Doctor (Matt Smith) and Clara (Jenna-Louise Coleman) must not only protect the crew but save the entire world from nuclear annihilation...

Doctor Who continues on BBC One on Saturday (April 13) at 6pm - check out these ten teasers for 'Cold War' below. Mild spoilers!
