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.

The work of art assumes the existence of the perfect spectator and is indifferent to the fact that no such person exists.

Old age believe me is a good and pleasant thing. It is true you are gently shouldered off the stage but then you are given such a comfortable front stall as spectator.
