Skins star Joe Dempsie has landed a role in Doctor Who.

The actor, who plays wildchild Chris in the E4 teen drama, will appear as a soldier who sees his comrades murdered by aliens.

However, he admitted that he had never watched the sci-fi hit before taking the part.

He told The Mirror: "I play a misguided soldier. To be honest I’d never seen the show before."

Other guest stars lined up for the fourth series include Alex Kingston, Sarah Lancashire and Felicity Kendal.
