Nolan said he aimed to make the third film a capstone to the “Batman” trilogy. “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,” he said. “And in viewing it as the finishing of a story rather than infinitely blowing up the balloon and expanding the story…unlike the comics, these things don’t go on forever in film and viewing it as a story with an end is useful.”
Bale also talked about how moving it actually was to read the “Rises” script. “…[I]t hit me that this was the last one,” he said. “What Chris couldn’t believe was how slow I read because I go back and re-read until I have it all in my mind. I was in [one of Nolan’s rooms] six or seven hours. It was dark when I came out. And I was smiling.”
Freeman also talked about leaving the “Batman” series for good. “The only drawback is that this is the last one we get to work on with him. And a lot of us won’t really get that until later,” he said. “It’s not until the curtain goes down that you think, ‘Jesus, that’s the last one.'”
