Watch the new trailer for Twice Upon A Time – Doctor Who: Christmas Special 2017

The magical final chapter of the Twelfth Doctor’s (Peter Capaldi) journey sees the Time Lord team up with his former self, the first ever Doctor (David Bradley – Harry Potter, Game of Thrones) and a returning Bill Potts (Pearl Mackie), for one last adventure.

Two Doctors stranded in an Arctic snowscape, refusing to face regeneration. Enchanted glass people, stealing their victims from frozen time. And a World War One captain destined to die on the battlefield, but taken from the trenches to play his part in the Doctor’s story.

An uplifting new tale about the power of hope in humanity’s darkest hours, Twice Upon A Time marks the end of an era. But as the Doctor must face his past to decide his future, his journey is only just beginning…

Twice Upon A Time is written by Steven Moffat, directed by Rachel Talalay, and executive produced by Brian Minchin. The 60 minute special guest stars Mark Gatiss as The Captain and Nikki Amuka-Bird as the voice of the glass woman.

You can watch the special at 5:30pm on Christmas Day on BBC One.
