Steppenwolf

Steppenwolf is a 1974 film adaptation of Hermann Hesse's 1927 novel Steppenwolf, directed by Fred Haines. The film made heavy use of visual special effects that were cutting-edge at the time of its release. It follows the adventures of a half-man, half-animal individual named Harry Haller, who in the Germany of the 1920s, is depressed, resentful of his middle class station, and wants to die not knowing the world around him. He then meets two strange people who introduce him to life and a bizarre world called the "Magic Theater".
