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.

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.

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.

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.

I want to get out of the way of the actors. I want to get out of their eye lines. I want to them to stop thinking they're making a movie. I want them to just go and live. It's like you take these great actors and put them in an aquarium of life, and just watch them swim. That's what makes editing tough because you get all these beautiful, unplanned moments.

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.

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.
