If you say to yourself, okay, I will not self-destruct. I don't have to be the most talented person. I don't have to be everybody's best friend, I don't have to be liked, I don't have to be successful, well, one thing I will not do is self-destruct. If you take that out, your chances for success just went up like 800 percent.

It's interesting to get older and realize that part of your job growing up in this profession is to help the next generation. More and more, with Boyhood and with Ellar Coltrane and with Emma [Watson], I start to see that role. There's no better way. Nobody wants advice, so you can't really give it. You just have to try to wish them well on their journey.

Good genre movies are a little bit like trying to write a haiku. There are certain things that you have to do to fulfill the audience's expectations, but inside that, you have complete freedom to talk about whatever you want. Who wants to see a movie about gun violence in America and class? But, if you set it in this terrifying, fun, roller coaster ride of a movie, you can talk about whatever you want. That's been the game that genre movies play, when they do it well.

The more kind of head trippy sci-fi. I always like that. I was a big 'Twilight Zone' freak.

When you start becoming really successful, the demons start to tempt you - the demons of vanity and self importance, drug abuse, the feelings of fraudulence. But, it's also a thrill. That's what I found weird.

The kindest compliments I have ever heard are when cops tell me Training Day and Assault on Precinct 13 inspired them to become cops. The funniest compliments I have ever heard are when people tell me that 'I love your band Sugar Ray.

The thing that makes a great genre movie is one that's not just entertainment, not just horror or sci-fi or whatever. The ones I love are the genre pictures with some subversive message underlying it all.
