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.

In general, I go to see the stuff that for me is, "Thank God for that actor, he's doing something that I never imagined; thank God for this filmmaker, because if this person didn't exist, this movie wouldn't exist." That's why I go to the movies. That, to me, is what's so exciting about this movie.

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.

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.

One of my favorite scenes of the movie [Valley of Violence] is when Ethan Hawke is sitting at the campfire with the dog.

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?

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.
