If you make just a straight scary movie, people are just - you don't know what they're thinking.

Humor is more so. For this, there's definitely moments that I think, "I know this part is really funny and I want to see people laugh." And they do and you go, "Yesss." That's really satisfying, because I'm so proud of the performances in the movie and everybody worked so hard.

One of my favorite scenes of the movie [Valley of Violence] is when Ethan Hawke is sitting at the campfire with the dog.

All those awkward moments - that's on the cast for doing such an amazing job. I think it was funny on the page, but when they did it, you definitely went, "Oh!" Watching it with a crowd that, like you said, was not expecting it to be funny, but then genuinely finding it funny, is totally a credit to their performances.

The first half [of Valley of Violence] was to endear you to all these people and give you all these archetypes that you're familiar with, and then the second half, just to see all those archetypes unravel like real people.

I always talk about movies a lot beforehand, and then we would get there, and I'd say, "Let's play around and see how it goes." And they would do it, and I'd go, "Well, that was awesome." It was really - I don't know, it was really special to watch them.

I did the movie [Valley of Violence] from two perspectives. You're with Ethan [Hawke] the whole movie, but for the first half, you're really with Ethan. For the second half, you're with him, but also you're with the bad guys because he kind of becomes the bad guy. No one's really good in the movie.
