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

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

I love Philip Glass' work, not only as a film composer but also as a musician. The film score work that he does always amazes and shocks me.

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

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

Certainly, it includes that. I want the story to be interpreted in as many ways as possible, and of course, the bad blood aspect of it included. For instance, perhaps this is a story not about the hereditary nature of evil, but rather you could interpret it from a different perspective, too.

If I want to relax and not do anything, I don't want to leave home.
