A rumor was recently reported that Joseph Gordon-Levitt would be playing Batman in Warner Bros' Justice League film and possibly make an appearance in Man of Steel.
The rumor stated that "Joseph Gordon-Levitt absolutely will be appearing in Justice League as the new Batman." Well as I expected, the news turned out to be false. Gordon-Levitt's reps have flat out denied that the actor has any kind of involvement with Justice League. Hollywood.com followed up with his reps who "have refuted the rumor entirely." So there you have it.
It would have been nice, but like I said in the original write-up, it makes no sense for Bruce Wayne not to be involved with Justice League. He's a key component to the team, and I just don't see how Justice League could exist without him. I also don't see Levitt's character outside of the universe that Christopher Nolan has created.
If this information was leaked out by studio insiders, maybe it was just to help create some buzz for the upcoming Blu-ray/DVD release of The Dark Knight Rises.
