George Clooney won't be giving advice to Ben Affleck on playing Batman, because he destroyed the part. Clooney is well aware of the downside to playing the Dark Knight, and declared:

“I am the least qualified person to comment on anyone playing the role of Batman since I so terribly destroyed the part. I tend to look at it like this — let's just see what the movie is before everyone starts beating him up. He is a smart man, he knows what he is doing."
