When you're a man, you're often in situations where you have to decide how far you're going to go in an argument. How big is the other guy? All this stuff that girls don't have to worry about as much, because that's not part of the equation.

Some actors really like to do only a few, some like Casey [Affleck] will do as many takes as there is electrical power. At some point, you'll say, "Listen, I think it's really good." And he'll say, "You sure? You sure? There's not some other way we should try it?"

I wanted to be a director first to protect my writing. I'm a playwright and you don't need to protect your writing when you're in the theater because everyone's there to protect the writing. When I had an idea for a film that I really cared about as my own, I wanted to direct it, and then I immediately became interested in directing in and of itself because it's such a deep art. You suddenly have all these tools at your disposal to tell the story.

I'm always struck when I go somewhere I've never been before, especially if it's in my home town, by just how different the atmosphere can be, and how disorienting it can be - especially if there's any kind of trouble.

Filmmaking, like any other art, is a very profound means of human communication; beyond the professional pleasure of succeeding or the pain of failing, you do want your film to be seen, to communicate itself to other people.

I would love to take control of the entire universe and for five years you give every movie the same widespread distribution no matter what movie and see if there's a real discrepancy between people coming to see science-fiction films or superhero films. I seriously bet there would be no discernible difference.
