And as some 粉丝 with particularly good memories may recall, one such visit has actually been chronicled in the series before, with the Doctor taking wife River Song there offscreen prior to the events of 2011 episode A Good Man Goes to War.
This year’s Doctor Who 圣诞节 special could be a rare double Doctor episode, with Peter Capaldi’s departing thirteenth incarnation being joined 由 the 1ST Doctor, played 由 An Adventure in 太空 and Time 星, 星级 David Bradley.
