What am I hanging around for? But I'm hanging around because it's still fun.

The past is history, the future's a mystery.

I work seriously with complete integrity. I never, never, never have offered a part to anyone who didn't deserve it, and I've never not delivered when I do offer a part. My word is better than a contract.

Most of my movies get about a third raves, a third vicious attacks, and a third in-between.

[Robert Downey was being singled out for] selective prosecution. He's a sweet guy who never did harm to anyone except himself. He's been doing drugs for 20 years and functioning for 20 years, and in those 20 years there've been hundreds of people who've been getting high constantly and behaved very destructively and have not been arrested. Robert's real problem is he gets caught.

I've struggled seriously to make movies with very little money, that I write, that I direct, that mean my life to me. The idea that I would offer a part to anyone for any other reason than that he or she was gonna be the best of anyone I could find is so disgusting to me. I don't give my best friends parts unless they deserve them. Ever.

To have six billion people on Earth, two billion of whom are carrying around a warped view of you? That has to register.
