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

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 don't really believe in the auteur theory.

I'd like to do a really masculine film.

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.

Certain subjects may no longer be taboo in cinema. But there are ways to treat them that still create shock.

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