I'm a scientist specializing in medicine. That makes me close to a technician... In some ways, human beings are more accurate than machines... As an independent producer, I have to be a type of skilled laborer. There were many times that I had to make a film quickly. At those times, I kept entertainment-value in mind. Not once have I made a film for the sake of making the film itself. My taste is in looking through the camera. Filming happens to correspond with that taste. Art films are what Hyun Mok Yoo makes. That's because director Yu wants to make art films. I just make films by following my heart, so the analysis I leave to all of you.
