Some audiences might find homosexuality an uncomfortable subject matter, and a character who is a Japanese collaborator is always uncomfortable.

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.

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

I tend not to use the humor which would only apply to Koreans, or which would only affect the Koreans, as much as I can.

I actually pay careful attention to that sort of thing - infusing humor into my films - because that's how important I think humor is.

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.

The point of revenge is not in the completion but in the process.
