In a traditional Western there's always the bravado, and it's almost like they're winking that they know they're in a Western - "Look how good I can spin my gun." In real life, when the bad guy kills somebody, or they're bad guy friend gets killed, they're upset, too, which is not typical in Westerns.

[Valley of Violence] was written for James Ransone. PJ's a friend of mine, I've known him for a long time, he's always like, "Dude, when are we going to make a movie together?" I finally called him.

To me, making a horror movie is about how you can present similar genre familiarities, but present them a little bit differently. Part of what interests me is the nonchalant realism of it, because you don't get that in the big studio horror movies. I like seeing someone walk around a house and sift through the drawers, and things like that, because that reminds me of what I would do, and of weird personal choices that people would make. That, in contrast to seeing someone get chased with a knife, makes it all the more interesting.

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."

You want to be able to say [to Ethan Hawke's character], "Dude, it's okay," but maybe it's not. Maybe he's not a good person. I don't know. That's the thing about people. There is no real good guy or bad guy [in A Valley Of Violence]. It's all context.

Toby [Huss] gets shot, or that part when [John] Travolta says this, or the part where Ethan [Hawke] says that cool thing - those details are the things that are interesting to me. So just acknowledging we don't have a lot of money [for Valley of Violence], so we're going to make a Western that's kind of contained, but we're going to make it super charismatic and we're going to make it memorable for what it is as opposed to what we couldn't afford.

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."
