Titicut Follies

From Wikipedia:

Titicut Follies is a black and white 1967 documentary film by United States filmmaker Frederick Wiseman about the treatment of inmates / patients at Bridgewater State Hospital for the criminally insane, a Massachusetts Correctional Institution in Bridgewater, Massachusetts. The title is taken from a talent show put on by the hospital’s inmates. (The talent show was named after the Wampanoag word for the nearby Taunton River.) In 1967 the film won awards in Germany and Italy. Wiseman made a number of such films examining social institutions (e.g. hospitals, police, schools, etc.) in the United States.
