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

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.

If you are watching my films and wondering, am I missing humorous speak because I'm not Korean? Am I missing out? You don't have to worry, because you're only missing probably about a few cents worth out of your ticket price.

Not only do I look at the playback with the actors, but I look at the on-set assembly footage with the sequences with my actors as well. These are the reasons why I take twice as much time to shoot a film in Korea. Thinking back, I remember on my first ever Korean film, I never used any playback or on-set assembly, so all I had to do was to tell myself it's just like making my first ever Korean-language film. After that, I felt right at home.

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

I believe there are more films that involve love and forgiveness than violence, but they often seem fake and are almost embarrassing to watch.
