There was a rumor that Nolan would be working on a JL movie in the future based on new Batman, Superman, Flash, and GL movies coming up (I know it's not true). Of course, this is just some people getting ahead of themselves. But it does make me think. Who's really important to having a Justice League movie?
IMO, we'd need Batman, Superman, Wonder Woman, Flash, and Green Lantern. I know some people would prefer to have all the big 7, and they could still be in it, but Aquaman and Martian Manhunter would have to debut in the actual movie, since I don't see them having successful solo movies. The rest could work though.
What do you guys think?
