"The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum - even encourage the more critical and dissident views. That gives people the sense that there's free thinking going on, while all the time the presuppositions of the system are being reinforced by the limits put on the range of the debate."

The director’s task is to recreate life, its movement, its contradictions, its dynamic and conflicts. It is his duty to reveal every iota of the truth he has seen, even if not everyone finds that truth acceptable. Of course an artist can lose his way, but even his mistakes are interesting provided they are sincere. For they represent the reality of his inner life, of the peregrinations and struggle into which the external world has thrown him.
