I've read all of Sarah Waters's novels which have been translated into Korean.

I became a film director, but I wasn't successful with my first couple of films, so I had to turn to becoming a film critic to make a living.

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.

Actors are professionals who deal with people's emotions and their thoughts.

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.
