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

Whether it's trivial or important, every choice has a moral aspect to it to a certain degree.

I cannot believe that violence depicted onscreen actually causes people to act out violently. That's oversimplifying the issue. If somebody commits a violent act after seeing violence in a movie, I think the question that needs to be asked is: would that person still have committed the act if he had not seen a violent film?

Actors, I think, are all the same. Both Korean actors and American actors are all very sensitive people, and they are all curious to know what the director thinks of them and how they are evaluated, and they try to satisfy the director. And they like it if you listen carefully to their opinions and accept them.

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

I live in a rural residential area. It's a great place for a walk. I'm at my happiest when I'm listening to my iPod while walking around where my feet take me.
