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."
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.
