The BBC has revealed a new promotional image for the 'Doctor Who' Christmas special.
The episode is entitled 'Last Christmas' (though presumably not after the Wham song of the same name), and is written by showrunner Steven Moffat.
The image shows Peter Capaldi looking suitably imposing in front of a pair of houses with Santa's sleigh and presents in the background. He's flanked by Jenna Coleman as Clara Oswald, and Nick Frost as Santa. Or at least someone claiming to be Santa.
Natalie Gumede ('Coronation Street'), Nathan McMullen ('Misfits'), Michael Troughton ('Enigma') and Faye Marsay ('Pride') will also appear.
The episode is expected to air on BBC One on Christmas Day. It sees the Doctor and Clara stranded on an Arctic base, under attack from terrifying creatures, according to the description.
The BBC's Christmas line-up also includes 'Top Gear', 'Miranda' and a production of the Roald Dahl story 'Esio Trot'. Harry Hill will also make his acting debut in the family drama 'The Incredible Adventures of Professor Branestawm'.
"This year's Christmas line-up on BBC Television is one of the best ever," said Danny Cohen, director of BBC Television. "There's world class talent, edge of your seat drama, outstanding comedy and fantastic storytelling. Across our channels we will bring families together and provide something for everyone."
