I don't understand why we have to experiment with film. I think everything should be done on paper. A musician has to do it, a composer. He puts a lot of dots down and beautiful music comes out. And I think that students should be taught to visualize. That's the one thing missing in all this. The one thing that the student has got to do is to learn that there is a rectangle up there - a white rectangle in a theater - and it has to be filled.
