Peter Capaldi’s final episode of Doctor Who this Christmas will feature Pearl Mackie as Bill Potts and be called 'Twice Upon a Time', it was revealed this evening (23rd July) during a cast panel at San Diego Comic Con. Viewers will have to wait until Christmas to discover exactly how Bill, who will appear throughout the episode, makes her return.
It was also revealed that the special will co-star Mark Gatiss in a guest role – as a World War One soldier, known so far only as ‘The Captain’.
As previously revealed in the closing moments of the 2017 series finale 'The Doctor Falls', the special will feature Peter Capaldi’s current Doctor teaming up with the First Doctor, played by David Bradley.
