An old picture of a Beatles jam session contains a man who looks almost exactly like Matt Smith’s Doctor. It makes perfect sense when you think about it. If I had a box that gave me access to all of time and space, chilling with the Beatles would be pretty high up on my list of things to do. I’m surprised it took The Doctor until his eleventh generation to get around to it. Steven Moffat is pretty excited about the photo too. He tweeted, “Clearly we’re going to make that."
So the only part I have seen with Capaldi is in "Day of the Doctor" and that was just his eyebrows. I'm super excited for him to be come (my) next Doctor. (I think this is the first time I have been excited for a regeneration!)
