[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.

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."

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.

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.

To me it's not so much that the movies are slow-paced as much as they are about spending time building a relationship between the audience and the characters. If you don't spend an adequate amount of time doing this, then how can you expect to scare anyone?

As filmmakers, the Western is a historic, cool thing to be a part of once in your life.

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.
