I like Oldman's acting but I don't know much about the guy himself. Is he a known douchebag?
His thoughts on Mel Gibson:
"I just think political correctness is c**p. That's what I think about it. I think it's like, take a f***ing joke. Get over it. I don't know about Mel. He got drunk and said a few things, but we've all said those things. We're all f***ing hypocrites. That's what I think about it. The policeman who arrested him has never used the word n***** or that f***ing Jew? I'm being brutally honest here. It's the hypocrisy of it that drives me crazy. Or maybe I should just strike that and say "the N word" and "the F word," although there are two F words now."
"The Jews are responsible for all the wars in the world." WHAT A KNEE SLAPPER.
"Alec calling someone an F-A-G in the street while he's pissed off coming out of his building because they won't leave him alone. I don't blame him. So they persecute. Mel Gibson is in a town that's run by Jews and he said the wrong thing because he's actually bitten the hand that I guess has fed him – and doesn't need to feed him anymore because he's got enough dough. He's like an outcast, a leper, you know? But some Jewish guy in his office somewhere hasn't turned and said, "That f***ing kraut" or "F*** those Germans," whatever it is? We all hide and try to be so politically correct. That's what gets me. It's just the sheer hypocrisy of everyone, that we all stand on this thing going, "Isn't that shocking?"
