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.

Actors are professionals who deal with people's emotions and their thoughts. So, working with this very intelligent, smart cast meant that sometimes I would only have to start speaking a word and these wonderful actors would immediately catch onto what I wanted them to portray, and how I wanted them to act.

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.
