Film is the manipulative medium par excellence. When you think back on the history of film and the 20th century you see the propaganda that's been made. So there are moral demands on the director to treat the spectators as seriously as he or she takes himself and not to see them merely as victims that can be manipulated to whatever ends they have.
There have been two great accidents in my life. One was the trolley and the other was Diego. Diego was by far the worst.
I remember at the age of five travelling on a trolley car with my mother past a group of women on a picket line at a textile plant seeing them being viciously beaten by security people. So that kind of thing stayed with me.
