Doctor Who Christmas Special Teaser Promises a Very Unhappy Holiday

Doctor Who Christmas Special 2014

It’s the most wonderful time of the year — or is it?

Judging by the trailer for Doctor Who‘s upcoming Christmas special, this year’s holiday will be anything but merry.

In the teaser below, The Doctor and Clara spend Christmas at the North Pole, where they encounter some terrifying new enemies. Plus, Nick Frost (Shaun of the Dead) briefly appears as a not-so-jolly Santa Claus.

Doctor Who‘s Season 8 finale airs tonight at 9/8c on BBC America.
