In an interview with IGN at the New York Comic Con, when asked about what was next for him, he had this to say: “DC has got some fantastic properties and I would love to take another crack at it at some point.”
After the success of Batman it seems likely that DC and Warner Bros would want to retain at least some of the Nolan magic for their fledgling movie push, and it wouldn’t be surprising if some talks had already taken place. What would you want to see him take on? The Flash? Wonder Woman? Or something more niche like Animal Man or Swamp Thing?
Jonathan was also asked about the ending of The Dark Knight Rises and he remained adamant that it is open to interpretation.
