It happens sometimes that when someone has a camera, they change; sometimes they change for the better.

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.

Yeah as the director I consider myself to be the coach, and my actors are my players. So I have to show them how committed I am, but I also want to lead by example. I think whenever you make a film, you start out alone, and then slowly start - you have to be a magnet. You have to attract people to you, to the project.

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 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.

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.
