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 feel like the job in editing is to let the movie tell you what it is. It's like sculpture. You just start taking away, you add a nose here, you cut off like the side of the cheek over here in the crease and you have a face. But it really reveals to you what it means to be over time, and if you have enough time.

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.

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.

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.

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.

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.
