Former Batman Michael Keaton is still a big fan of the character that made him into Mr Big Time, claiming that when it comes to superhero battles the B-Man crushes them all.
He has no hard statistical data from DC Comics to back up this wild claim, though, simply saying in an interview that: "Everyone needs to stop asking the question of who could beat up who. Batman kicks everybody’s ass. And if they won’t, I will, Bruce Wayne will."
Keaton was speaking during promotional duties for his new movie Spotlight, which also stars Mark Ruffalo -- who's previously played the Hulk. Spotlight doesn't solve any questions about whether the Hulk could beat Batman, though, as it's a sort of drama about the boring lives of journalists. Proper journalists, mind you, not ones who say things about superheroes on blogs.
