Young Törless (1966)

At an Austrian boys' boarding school in the early 1900s, shy, intelligent Törless observes the sadistic behavior of his fellow students, doing nothing to help a victimized classmate—until the torture goes too far. Adapted from Robert Musil's acclaimed novel, Young Törless launched the New German Cinema movement and garnered the 1966 Cannes Film Festival International Critics' Prize for first-time director Volker Schlöndorff.

Unfortunately the movie Young Törless is not yet available on HBO Max.
