You're limited to one image, but you can have 50 audio tracks. It's something you'd be foolish not to experiment with. So I'm also very interested in sound that happens offscreen. I think that's a way to expand the scope of the movie. And it's all very planned out from the script stage. For me, sound design is a major part of the narrative. I think that's what makes working with certain people on the producer level difficult.

I found Jumpy on YouTube. I wrote a movie about a guy with a dog and was like, "What have I done? This is going to be a nightmare. We're a small movie and we're never going to be able to do this."

In general, I go to see the stuff that for me is, "Thank God for that actor, he's doing something that I never imagined; thank God for this filmmaker, because if this person didn't exist, this movie wouldn't exist." That's why I go to the movies. That, to me, is what's so exciting about this movie.

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.

It definitely could have been a horror story [Valley of Violence], oh my God, if the dog was impossible. So could the horses.

You have to. But I generally try - I'll creep in the back. I'll be outside. I'll pace around. I don't really get that nervous about whether people like [my films].

I just really like seeing mundane stuff in movies. It's realistic.
