It's this long monologue [in Valley of Violence] with Ethan Hawke talking about life and everything with a dog. That's not in movies. Hopefully when people think about the movie when they go home, they're like, "That's weird. He's maybe crazy. He's talking to a dog the whole time."

Tommy Nohilly, who plays Tubby [ Valley of Violence], he came down to see the movie for the first time and I was like, "You've got to come just to see people react to your [big scene]." I knew that would go well, but it's satisfying to me when he's sitting there and it actually does.

I don't really get that nervous about whether people like it. You can't do anything about that. It's more technical. You spend two years of your life obsessing, picturing sound details, and you work so hard to make a movie a certain way, that you get there, and you're like - is it loud enough or whatever, so that this experience with everybody in this room is the fairest chance I can get. And then if you like it, cool, and if you don't, whatever.

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.

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.

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

Technology has just been the major progression of the last 15 years - instant communication. That stuff has gone so global. That's what's interesting about it. When someone sits down in front of a computer, it's the same everywhere in the world, and it's the same screen looking back at you with the same Google, and there's no individuality to it. So I decided it would be kind of visually uninteresting to have in my films.
