The Enigma of Kaspar Hauser movie review (1974)
Werner Herzog's films do not depend on "acting" in the conventional sense. He is most content when he finds an actor who embodies the essence of a character, and he studies that essence with a fascinated intensity. Consider the case of Bruno S., a street performer and forklift operator whose last name was long concealed. He is the center of two Herzog films "The Enigma of Kaspar Hauser" (1974) and "Stroszek" (1977). The son of a prostitute, he was locked for 23 years in mental institutions, even though Herzog believes he was never insane.
