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.

I don't think you want to preach to people. I don't think In A Valley Of Violence, and the same with The Sacrament, there's a social commentary and a political element to both the films, but it's not like, "Think this because I think this."

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.

They're both [Ethan Hawke and John Travolta] so good. It's hard to explain. But they're consummate professionals and you see the little choices they make - you see it in their eye. You see these little details they do where you go, "That's why they're them."

There are people - I think this is why there are so many commercial directors doing well in big studio movies, for whom it's not a personal choice - it's "What's the coolest, most effective way to make them laugh, make them scream?" It's a very calculated approach. And that's different. It's not better or worse. It's just a very different approach to filmmaking. That's always been the case.

I've done it with all my films. I always keep an eye on the first time I show it because... I don't know. Neurosis.

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