Shock Corridor

Shock Corridor is a 1963 American psychological thriller film starring Peter Breck, Constance Towers, and Gene Evans. Written and directed by Samuel Fuller, the film tells the story of a journalist who gets himself intentionally committed to a mental hospital to solve a murder committed within the institution. Fuller originally wrote the film under the title Straitjacket for Fritz Lang in the late 1940s, but Lang wanted to change the lead character to a woman, so Joan Bennett could play the role.
