Peter Capaldi’s Time Lord is seen standing alongside his former self in a newly-released Doctor Who photo.
Capaldi’s final outing as the twelfth Doctor has been teased in the image which shows him standing in an arctic snowscape alongside the first Doctor (David Bradley) and assistant Bill Potts (Pearl Mackie).
The Doctor, sporting a slightly torn jacket from his battle with the cybermen in the latest series, stands with his companions staring into the sky while a golden glow covers his left hand.
Named Twice Upon A Time, the Christmas Day special will feature enchanted glass people stealing their victims from frozen time and a First World War captain (Mark Gatiss) taken from the trenches to play a role in The Doctor’s story.
Billed as an uplifting new tale about the power of hope in humanity’s darkest hours, Twice Upon A Time will also mark the first time viewers catch a glimpse of the first-ever female Time Lord, Jodie Whittaker.
The 60-minute special also stars Nikki Amuka-Bird as the voice of the glass woman and is the final episode to be penned by Steven Moffat.
