The reason why I always wanted to make an American film was because of the Western genre. It is something that I would very much like to make in the future, because it's very uniquely American, and I can't make a Western film in Korean.

I'd love to do a sci-fi movie, a western, or an espionage thriller. But I'm not going to limit myself. If a good script comes along, I'm not going to discount it because it doesn't fit into one of these genres.

Actually, I can't stand watching violent scenes in films; I avoid watching horror films. I don't tend to watch action films mainly because I find them boring, but I watch the films of David Cronenberg and Martin Scorsese, usually in a state close to having a heart attack. I'm a complete coward. I make violent films as a result of my sensitivity to violence - in other words, my fear of violence.

I guess I probably make violent films partly because I can't express my anger in my real life very well.

I have always meticulously storyboarded my films from beginning to end.

A film set is a workplace for me; it's my office, and nobody really wants to be in a stressful work environment.

Certainly, it includes that. I want the story to be interpreted in as many ways as possible, and of course, the bad blood aspect of it included. For instance, perhaps this is a story not about the hereditary nature of evil, but rather you could interpret it from a different perspective, too.
