And Moffat's man-crush on the Troughton era continues unabated.
Lest you think I'm mocking, I'm genuinely not. It's a pretty cool thing.
Though I will say that between this revelation (which Tom Spilsbury confirmed on Twitter in a series of now-deleted Tweets) and Moffat's paeon to "Evil of the Daleks" on the Advent Calendar, I'm starting to get suspicious that there may be a missing episode announcement in the near future.
