"There are always forces at work in a society, certainly in America, which are really forces of censorship -either religious bodies or zealots who are always putting pressure on things, whether it's books or art or film. And all art is fundamentally subversive, because it upsets people's perceptions, their notions about society. Therefore, art is dangerous, but good art is always making us reassess our thoughts and feelings about how we relate to other people. There are always people who fear that and want to suppress that."
