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.

Humor is more so. For this, there's definitely moments that I think, "I know this part is really funny and I want to see people laugh." And they do and you go, "Yesss." That's really satisfying, because I'm so proud of the performances in the movie and everybody worked so hard.

It's unreal. I mean, the dog backflips. It's amazing. Google Jumpy on YouTube - I had seen the dog first and I was like, "Y'all don't even know."

It's Ethan Hawke and John Travolta [in Valley of Violence]. It's awesome. They're awesome.

You have to. But I generally try - I'll creep in the back. I'll be outside. I'll pace around. I don't really get that nervous about whether people like [my films].

I think you make the movie in your head that you have to make, and you have to get it out of you. You have all these pretentious reasons why you want to do it, and you set out to accomplish them. And you think "This is important for what I'm trying to accomplish for the story," and I think those reasons will come through to an audience, and they will find it. That's the best you can do.

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.
