The folks over at Movieline caught up with Christopher Nolan at a museum event for Hugh Jackman, and they were able to ask the director/producer about the rumors of Joseph Gordon-Levitt taking over the mantle of Batman in future films.
Specifically they asked if JG-L would make a cameo in next summer’s Man of Steel, which Nolan is producing, as a teaser for his official appearance as Batman in Justice League.
Nolan’s (smiling) response:
“I can’t talk about that. You know that.”
What a wry way to answer that question. Could be misdirection, could be contractually obligated nothingness. Wait and see.
