Joseph Gordon-Levitt On Dark Knight Rises Spin-Off
Actor staying noncommittal over prospect of a solo movie...
His character took over from Batman as the guardian of Gotham City at the end of the movie - and it was also revealed that his real name was "Robin".
He told ShortList: "That's not up to me. I don't have the rights to that character, but I pick my projects the same way.
"If there's a script I find inspiring and a filmmaker I have a connection with, I'm interested."
And he revealed that he was among a select few who knew about the ending all along.
He said: "He told me before I read the script. I was one of a handful of people who had a complete script for the last pages, so I knew all along.
"I was happy to keep it a secret. It's such a fantastic ending, I think. And I certainly didn't want to spoil it.
"It's a movie that I'm enormously honoured and proud to be a part of and the last thing I would want is to contaminate anybody's experience of it."
It is claimed that Batman could appear in the planned Justice League movie.
