Peter Capaldi's first full season as the Doctor is over, and now it's time for his first Christmas special. He appeared briefly in last year's "The Time of the Doctor," but this time it's all about him and Clara. The official synopsis calls this their "Last Christmas." It's the name of the episode too, so maybe it's the title of a location?

Anyway, rather than celebrating the holiday in a calm and merry style, the Doctor and Clara get trapped on an Artic base and are under attack. But, don't worry! They've got back up in the form of Santa Claus - and he's played by Nick Frost! See a photo preview of the episode in the gallery below.
