If Man of Steel
is a hit, I don't see any reason, if they use Henry Cavill's Superman and include a Batman and a Wonder Woman, why the audience would be intimidated by a Justice League
movie. It would probably make it a more sure thing if a new Batman was already established also, but, I don't think that's even definitely necessary.
