Death is a part of life, and eventually I assimilated that completely.

Boxing is not coming back. There's not going to be a new Ali or a new Tyson. What's happened to movies is happening to boxing-that is, too much availability of alternative, similar entertainment. Movies started to become diluted with the advent of television; that has been mirrored by the dilution of boxing, with kickboxing and absolute, extreme homicidal fighting.

You will never convince anyone to do anything unless you believe it should be done.

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.

The collaborator has to be someone who understands that his role is to help you articulate what you want, but at the same time is not just going to be mechanically obeying, but adding to, supplementing, and coming up with stuff.

In a way, I think that the movie Fight Club [1999] did a weird, negative thing to boxing, culturally. I mean, it is sort of similar to what has happened to the novel. For however many good novels are written, the novel itself has completely lost its place.
