“I don't enjoy good food. I don't enjoy flashy cars. I don't care if I live in a dump. I don't enjoy good clothes. This is the best I've dressed in months.”
“When I finish a film, I like to drastically change my appearance. I get sick of looking at the same thing in the mirror for months at a time. So when a film's over, I'll do something like shave my head.”
