There is an old story of how the cathedral of Chartes was struck by lightning and burned to the ground. Then thousands of people came from all points of the compass, like a giant procession of ants, and together they began to rebuild the cathedral on its old site. They worked until the building was completed—master builders, artists, labourers, clowns, noblemen, priests, burghers. But they all remained anonymous, and no one knows to this day who built the Cathedral of Chartes.
In a way, Bergman is right, as the auteur theory has allowed some filmmakers the right to produce painfully self-absorbed work with little social purview, and others to never move outside a rut of established convention. Instead, most art cinema exists in between these extremities; the director is obviously important to the films he produces, but in order for the work to have social value, it must not be limited to individual reflection. Perhaps in art cinema, more than any other genre, the films strike a balance between social value of new modes of filmmaking and the significance of an auteur's canon.
That isn't to say there are no establishments within art cinema. The model is more abstract than—and in many ways runs counter to—the modes of classical production, but there remain certain tendencies in art cinema which indicate, while these films may not be necessarily formulaic, they also do not exist on such an abstract, independent plane.
