Well, since I'll be dying in November, I hope you all will come to my funeral. Not to excited for the new hunger games, but there is the new thor movie coming out in November as well, so this still applies xD
in "The Big Bang" when he explodes the Tardis he goes back through the moments with Amy and the time when he is talking to her is the future Doctor not the Doctor from episode hence why he has the jacket on.
Okay so I totally think that Peter Capaldi looks like an older Arthur Darvill which works really well, because Rory the Roman and then he plays a Roman in this episode! It just works so well. Even though it's not actually a thing.
