Titicut Follies(1967)

Employing methods of direct cinema–observation, limited stylization, and non-intervention–this stark look into the State Prison for the Criminally Insane in Bridgewater, Massachusetts shows its denizens, who were often kept in barren cells and infrequently bathed, forced to strip naked publicly, force feeding, and the indifference and bullying by many of the hospital's staff.
