And as some fan 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 Natale special could be a rare double Doctor episode, with Peter Capaldi’s departing thirteenth incarnation being joined da the 1ST Doctor, played da An Adventure in spazio and Time stella, star David Bradley.
“Do te feel that River Song’s story is done?”Showrunner replied: "Well, yes, that does seem like the end to me. Except, of course, it isn’t, and can’t be. There’s always the chance that River will mostra up again."
