I think one of the reasons movies are the quintessential modern art form is that it is partially a business. The director needs a crew - the writer, the producer, etcetera - and to have that, he needs money.

When you're talking horror or sci-fi, you're working in a genre that has loosely certain thematic elements, or, you could even call them rules. But rules are there to be broken. I think that young filmmakers should go all the way back to the history of horror, from silent films like "Nosferatu", and through to today's horror films, so they understand the history of horror films and what has been done. Understand that, and then add something new or original.

In order to create art today, you have to compromise your art somewhat and be a businessman.

I was young, so I was part of youth culture. The years went by, I became older and no longer part of youth culture, and I became more dependent upon the young people in the office and my own children.

The safest genre is the horror film. But the most unsafe - the most dangerous - is comedy. Because even if your horror film isn't very good, you'll get a few screams and you're okay. With a comedy, if they don't laugh, you're dead.

You can make a movie about anything, as long as it has a hook to hang the advertising on.

I'm not going to shoot seven days a week. I think it's counterproductive. I think you're going to have people stumbling around after a couple of weeks.
