It's always been the case that you have the really rich, and the really poor. But hey, look, all the great empires have their periods where they rule the world, and then they crumble.

I don't mind getting punched in the nose by a guy standing in front of me. It's getting stabbed in the back that I can't handle.

I had achieved so much success in my career and then had this spectacular fall from grace that left me unemployed and living in a town, Los Angeles, that is built on envy. Once you fall, people don't really root for you to come back again. I'd go to restaurants where I always had the best table and half the time they wouldn't even let me pay. And then when I stopped making movies, the same places wouldn't even give me a lousy table, never mind the best one!

I started having some memory-loss issues. I took a neurological exam, and they said, "Well, you should stop fighting now." And I kept begging them for one more fight, one more fight, and the doctor said to me, "How much are they going to pay you?" I was supposed to fight three more times, and one would have been for a cruiser belt. So I said, "I just need to fight three more times." He said, "Listen, you can't even get hit in the head one more time, your neuro is so bad."

By the end of the shoot [of Wrestler], my trainer was pushing me up three flights of stairs to my house and holding my arm like I was an old cripple. I had three MRIs in the first two months of working on the film. I felt like it really was over by the time we started shooting the movie.

Julian Schnabel painted a picture that he dedicated to my character in Rumble Fish. It was called The Motorcycle Boy. I remember when he brought it over to me at the Mayflower Hotel [in New York] years ago. This is when you and I knew each other.

When I was like 12 or 13,Muhammad Ali gave me a pair of his trunks that were white satin with gold stripes. They were full of blood, and my mother threw them away. I think it's the first time I ever cursed at my mother.
