Ethan [Hawke] just - they got along great. He got to act with a dog, for real, and it felt like Jumpy was acting with him. It was a surreal thing to watch. When you watch the movie [Valley of Violence], you just kind of accept it. But if you do think about how we show - there's a dog and a movie star interacting - and you buy it. That's crazy.

It's very important to me to find ways to relate the audience to the characters. This is the first thing to go in most mainstream horror films.

Everything Jumpy could do [in Valley of Violence] was too much. If I put it in the movie you would all check out. When he wraps himself up in the blanket, that's as far as I could go, and that's not even close. The dog's amazing.

I like movies that leave things in the hands of the audience.

Sometimes I look at it [Valley of Violence] and go, "How did we do that?" But it's a credit to Ethan [Hawke], he had done White Fang, so Ethan is like, "Oh God, that's right."

I think having funny characters is just one way of having three-dimensional characters.

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