Jean-Marie Straub and Danièle Huillet have used Arnold Schoenberg’s 12-tone opera as the basis for a rigorous and fascinating exercise in elemental cinema (1975). A film about film—the meaning of long takes and short shots, of camera movement and static composition, of angles and perspectives. Schoenberg is Greek to me, but Straub and Huillet’s investigation of the medium is an important experience for anyone interested in the way film represents reality—or fails to.
