Roger Ebert - Host: [Theory on casting Batman] As for Clooney as Batman, I realized this time... it doesn't matter who plays Batman, I think they cast him according to the chin, which is all you can see when he has the costume on. Because there's no real interest in the Batman and Robin characters, it's always the villains. But this villains are not really up there with Jack Nicholson or Danny DeVito or Tommy Lee Jones.
