You have to be realistic in the use of blood in the movies. There is a little bit more than a gallon in a human being. If you have a few thousand people, that makes a lot of blood. I'm very realistic in my use of blood.

When I approach a story or movie, the story is the most important thing.

In the horror genre, unfortunately you sometimes have the studio tell you, "No, go with more unknown people because it's a scary movie," and I disagree.

I try to think about me, as an audience member, and it [inspiration for movies] comes from there.

Casting is so important in horror. It's so important to have strong actors to tell a story because, if you don't believe in the character, how can you be scared for them?

I follow my instincts and I always think about what movie I would like to see. If I want to see it then I'm guessing that some other people might want to see it as well. I never try to think about what people will love or will like, because when you start to think for other people that's where you lose track of the real motivation.

I'm always on the side of the characters, rather than the side of the people attacking them. I get realistic. It's not gratuitous.
