I became a film director, but I wasn't successful with my first couple of films, so I had to turn to becoming a film critic to make a living.

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

Actors are professionals who deal with people's emotions and their thoughts. So, working with this very intelligent, smart cast meant that sometimes I would only have to start speaking a word and these wonderful actors would immediately catch onto what I wanted them to portray, and how I wanted them to act.

In Korea is what I do is I watch the playback of each take with all of the actors and spend a lot of time discussing each take. Also, I use the process we call auto-assembly because I storyboard my entire film right at the beginning, even before pre-production ever begins, so my vision is already laid out on the storyboard for everybody to share. It enables the on-set assembly person, as we call them, to cut together each take into a sequence. This enables a director to review the take within the context of the sequence of the scene.

I've grown up watching a lot of Western genre films on TV, and America is not just a country, but it's one of the most important countries in the world, and examining the process of how this nation came to be, it's an important thing, even for outsiders.

Sometimes you need these warm, human moments - something that feels close - to help things along.

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.
