I love Philip Glass' work, not only as a film composer but also as a musician. The film score work that he does always amazes and shocks me.

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.

If you would ask me what my ideal process is, I would say, long pre-production, long production and long post-production.

In my opinion, all relationships between people have some sort of violence, and it is central.

I don't really believe in the auteur theory.

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.

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