Shock Treatment is a 1964 American neo noir drama film directed by Denis Sanders and written by Sydney Boehm, based on Winfred Van Atta's 1961 novel of the same name. Taking place in a mental institution, starring Stuart Whitman, Carol Lynley, Roddy McDowall, and Lauren Bacall. As one of many post-Psycho films dealing with insane, Bacall disliked the film intensely, calling it the worst of her career despite its cult following in later years.
