Both of them do it. Clooney needs to get out and do some better films. I really liked him in Three Kings and Syriana, and now he's trying to play Danny Ocean. Yeah, he does it well, but he's a bastard of a character and no mistaking.
Yea, those were good movies ...although Syriana was a bit slow now and then it seemed to me (although I must admit, it's been a while since I watched it.)
