I've had to cut my mom out of a movie before - it's ruthless, editing. But it's also so necessary; because once you start taking away, it's like sculpture, you can really start feeling the shape of the whole.

From making documentaries all these years, it doesn't feel right to lead someone. In narratives, I'm always trying to shoot as though it's really happening, and I trust my actors are going to make decisions that I'm going to be following. I want to follow them. It feels dishonest to be pulling back in that opening shot and leading him to his destiny.

So I don't think being an artist you can ever satisfy - the moment you do get satisfied is the moment you're done, really. I'm actually starting to bug out now, because it's not enough. I get joy and pleasure in the movies out there in the world that people are seeing, but for me, it's about making it. That's why I do it, is to make it, to deal with my life.

Sidney Lumet is one of my favorite filmmakers. I feel like his approach to filmmaking was always so human. He was always making movies about the people. He wasn't about the tricks, you know what I mean? From 12 Angry Men on. Another film of his which I really, really love is Prince of the City, with Treat Williams, which is kind of a lost classic. Lumet is one of those film heroes that changed movies for everyone.

Making a film is like making a mixtape. You're collecting all this stuff and putting your favorite stuff into it: you have actors that you like, characters that you're interested in, moments you want to explore, themes you want to deal with, music that you want to put in. It's a pastiche of all these things that deal with how you see the world. You're just trying to make a love letter, a gift.

I don't really collect anything. I grew up in a family that collected things and then they'd get sick and people die and then they have their basements full of stuff that goes from one box to the next, so I try not to get sentimental with stuff. I just try to collect memories.
