I have always meticulously storyboarded my films from beginning to end.

I don't usually watch a lot of TV, but Mad Men changed my perspective. I admire Matthew Weiner who came up with the idea and wrote such a great TV series, and the broadcasting company for being bold enough to air such a series.

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

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.

When I was growing up, we were taught in school that North Koreans, and especially the North Korean leadership, were all devils.

I grew up in a very Catholic family. Up until puberty, I would go to a Catholic church every week.

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.
