The experience of going to a theater and seeing a movie with a lot of people is still part of the transformational power of the film, and it's equivalent to the old shaman telling a story by the campfire to a bunch of people. That is a remarkable thing, if you scream and everyone else in the audience screams, you realize that your fears are not just within yourself, they're in other people as well, and that's strangely releasing.

Horror films don't create fear. They release it.

I don't want to rescind American directors but I think that European directors in general, because of the size of the nations in Europe are exposed to all different cultures, they can easily travel from one distinct culture to another in a matter of hours - you can drive for two weeks across the United States and you're in the same basic culture - so there is a certain breadth of understanding and sophistication that they bring to it and frankly, in some cases they are less expensive than American directors.

I wrote, I think, half a dozen films that were completely out of genre. Comedies, love stories, even one serious film about Vietnam, and we couldn't get backing for any of it. And we both sort of drifted from making, at that time, serious money on Last House to going through it all in the course of almost three years and only getting offers to do something scary again.

The first monster you have to scare the audience with is yourself.

I've done a few interviews where I realized that 9/11 was the ultimate home invasion, not to be glib about it. You know, where the place that you think is safe and the people that you think are safe and far from evil are suddenly just slaughtered by it, and you have no control over it.

But I made him the Deputy Secretary for Homeland Security because that added an element of political espionage.
