The actor already comes with emotions to the scene: fear, the fear of being in front of the camera. It is this fear that spurs the emotion of the scene. I too am afraid; I don't know exactly what I am searching for. On the set, we are all participating in this fear together.
I don't watch my own past films: when I watch them, I find they don't work very well, because I have changed. If I continue to make films, in fact, it is because I always want to repair my films. My inner rhythm has changed; I have changed. I have changed my way to film.
