Great directors ... are often governed by a sense of responsibility, and their films in turn are governed by the methods ... through which that responsibility is fulfilled. There's the responsibility to continue the theatre (Griffith, Bauer, Protazanov), the responsibility to the "natural world" (Rohmer, Straub & Huillet), a newspaperman's responsibility to the public (Fuller, Sembène, Chaplin, Ivens), a responsibility to avoid sentimentality (Pialat, Davies), a responsibility to avoid "cinema" (Bresson)-the list goes on. What these responsibilities have in common is that they are as capable of destroying a film as they are of creating one.
