To live is to be someone else. Feeling is impossible if we feel today as we felt yesterday: to feel today the same thing we felt yesterday is not to feel at all--it's merely to remember today what we felt yesterday, since today we are the living cadaver of yesterday's lost life.
All films are learning processes. I am still trying to work out how you make a movie. I didn't study at film school or any of those things. I didn't bother with film theory.
