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'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.

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.

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.

There's something so glorious in giving control to the world. I think that's what I'm trying to do in my films-control the world but also let it be chaotic, let there be life.

When I made my student film, a feature, nobody wanted to talk to me and I was, like, in the desert for 12 years.

I love crosscut parallel storytelling, like we did in Blue Valentine. I love how Alejandro González Iñárritu has done it, and Quentin Tarantino, and Francis Ford Coppola, and all the way back to D.W. Griffith - this parallel editing is an effective way to tell stories. It's like juggling, like keeping a lot of balls in the air and seeing how they come down.
