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.

I tell the actors that the biggest gift they can give me is to fail. And that the second gift they can give me is to surprise me.

There's one rule that I have on my movies, which is that anything that you want to do, you can do. But! There's a flip side to that, which is that anything I want you to do, give it a try also.

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.

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 always say writing is like dreaming, shooting is like living, and editing is like murder, because you take all these gifts that actors give you, and you cut them.

You can never maintain just pure happiness. In my life, I want full emotion. I want equal parts happiness and sadness.
