That's what's interesting about people. It can be funny, but when [John] Travolta got there and did [comic moments] you're like, "Oh! This is really funny." Or when Karen [Gillan] and Taissa [Farmiga] do something, I'm like, "This came out so much funnier."

The second half [of Valley of Violence], you're with the guys that you should hate, but when you start seeing what their real lives are, you're like, "I do hate you, but at the same time, all right - maybe take it down a notch." The complications of all that are what's so interesting to me, those esoteric details - that's what people will hopefully take away from the movie.

Really, I wanted to make a movie [Valley Of Violence] about: How does violence affect people? This is a take from me on how violence affects people.

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."

It's funny, because I don't think of my films as "slow-burn." I don't even know if I was familiar with the phrase until people started labeling me with it.

With my horror movies or with this movie [Valley of Violence], same thing. The subtext of this movie is what to take away from it. Plot is never something that's been my driving force as a filmmaker.

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.
