One of the worst things you can do is have a limited budget and try to do some big looking film. That's when you end up with very bad work.

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.

I look for the ability to work. Directing is hard work. They don't teach you that in film school. Critics are not aware of it, but it is hard, physical work.

Somebody who moved up very fast was Jim Cameron, who was a young guy out of - I think he came from Arizona, from some community college there, and he was building model spaceships, on a picture called Battle Beyond the Stars.

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.

People gravitate occasionally to the brilliantly made art low budget films, which is maybe one out of every five hundred low budget films made.

First, you have to be intelligent. I have never met a successful director who isn't intelligent. A director who is not intelligent might have one hit picture, but he won't be able to follow it up. So I look for intelligence.
