“I know we’re all used to the sort of Marvel movies, which are just kind of endless series. They don’t really have a beginning, middle, and end. But I think Nolan very much thought of that movie as a conclusion, and there’s a theme that runs through all three of those movies that begins in the first movie, runs through the second movie and it concludes in that moment where he says that Batman is more than a man, Batman is a symbol. And so to have another man other than Bruce Wayne kind of becoming Batman at the end of that trilogy, I think that’s the perfect ending to that story.”
