Your actors need to trust you as a director, but normally, I think you just need to have an open communication between the actors and the director. I think the director needs to really paint his or her vision to the cast and let them know the kind of mood that he or she is making. I think that's very important.

What makes horror movies work is the idea that "oh my God, what would I do if I were in that situation? How would I get out of that alive? What would I do if I saw the door to my closet creaking open in the middle of the night and a doll on a tricycle comes riding out?"

Not many people realize this, but I'm a really squeamish guy. When I watch other horror films that are really over-the-top with their blood and guts, I cannot watch it. So if my threshold to something onscreen is at that level, you can imagine how my threshold is to all the pain and suffering that is happening in the real world.

One of the things I tried to do is to kind of talk my actors through the scene, but at the same time let them know how I plan to shoot the film and just give them an insight into the way I'm thinking, so that when they're acting out their scene, they can kind of see it in their minds' eyes.

When you make movies, I find that I never have time to go to the movies and enjoy movies like I used to, because I'm so movied out, right, I'm so filmed out that the last thing that I wanna do is with the little spare time that I have is stick in a dark room and watch more stuff on the screen.

I realized that my camera work could help me in a lot of ways to put the audience in the driver's seat, so to speak, to get them in there with the action, and to get them as close and be as intimate with what was going on on-screen as possible.

For me, the sound design and the musical score is a big part of what makes scary movies work.
