The 802nd episode of Doctor Who airs on BBC1 (the 104th episode since the series’ revival). This Christmas-themed episode sees the exit of Matt Smith as the eleventh Doctor (revealed during the story to actually be the thirteenth and final Doctor), but bends the long-standing mythos surrounding regeneration in time to introduce Peter Capaldi as the new Doctor. The production staff behind the scenes will remain largely intact for the transition into the Capaldi era.
