Moses receives the summons from God but cannot communicate the idea of a single, invisible deity to the Jewish people. Moses and Aaron is both a faithful adaptation of Arnold Schoenberg's twelve-tone opera and a radical film experiment by Jean-Marie Straub and Daniele Huillet, long esteemed as the most uncompromising voice in modern European cinema. Their style is minimal and meticulous, resulting in a work of great simplicity and power.
