We finally have news from the horse's mouth, i.e. Chris Nolan himself!! Since "The Dark Knight" was released, fans have clambered over each other to learn about the future of Batman 3. Over a year later, we finally have something to go on!
"Without getting into specifics, the key thing that makes the third film a great possibility for us is that we want to finish our story, and in viewing it as the finishing of a story rather than infinitely blowing up the balloon and expanding the story. We have a great ensemble, that's one of the attractions of doing another film, since we've been having a great time for years."
Great start!! But there's more! Nolan also commented on the connection B3 will have to the new Superman movie he's "godfathering."
"Each serves to the internal logic of the story. They have nothing to do with each other."
And that's the whole kit and caboodle.
