Climate change is critical to me because I'm a parent; I feel a sense of responsibility to the future. I'm not going to be around to see its worst effects, which are going to be hitting in the 2030s, '40s, '50s, but my kids will.

A director's job is to make something happen and it doesn't happen by itself. So you wheedle, you cajole, you flatter people, you tell them what needs to be done. And if you don't bring a passion and an intensity to it, you shouldn't be doing it.

I don't look at scripts. I just write them.

My mother was a housewife but she was also an artist. My father was an electrical engineer.

I tried [being a mogul]. It bores me. I don't really want to produce other people's movies. Because they're either grown-up filmmakers like Steven Soderbergh or Kathryn Bigelow that didn't really need me - and I've produced both of them. It's fun to sit around with them and be collegial, but they don't need me. They can make the film without me. I make my own stuff. There are tons and tons of other things I'm interested in that have nothing to do with movies or are documentary projects.

Your only competitors are your past achievements.

Pick up a camera. Shoot something. No matter how small, no matter how cheesy, no matter whether your friends and your sister star in it. Put your name on it as director. Now you're a director. Everything after that you're just negotiating your budget and your fee.
