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.

You can look at what's happened to America in the last years and say a lot of people were asleep. A lot of people were not staying awake and watching what was going on and facing the pain of that and dealing with it.I don't care if the rest of the audience doesn't think along those lines at all, because the audience is a huge spectrum of people, from people who are introspective to people who just want to be scared and have fun, and all the points in between.

I think the important thing about staying creative and staying sharp and original is not to look back too much, and to kind of look to where your vision is going now. But I have felt over the years a definite progression or arc from feeling guilty about what I had done with the first one, because certainly there was all that fundamentalist guilt that came pouring back in. Feeling like I'd done something horrible, "I'm a despicable person and I'm perverse," and all these things, to a sense of the power and the necessity, in a sense, of horror films and dealing with dark material.

I learned to take the first job that you have in the business that you want to get into. It doesn't matter what that job is, you get your foot in the door.

It's quite rare that you make something and think that you did something that no-one else had done.

There was a generation of kids who were just kind of emulating distant heroes and wearing peace symbols, and parents who were thinking of themselves as liberal and removed from barbarity, but it also was the era of Vietnam. I very much was influenced - and I think the whole country was kind of in a state of shock - for the first time seeing the horror and cruelty of war.

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