Behind Locked Doors

Behind Locked Doors is a 1948 film noir directed by Budd Boetticher and starring Lucille Bremer, Richard Carlson and Tor Johnson. At the behest of a pretty reporter, an amorously forward private detective goes undercover as a patient in a private sanitarium in search of a judge hiding out from the police. The two plan to split the $10,000 reward for the judge's capture. As the reporter and detective begin to fall in love, the detective also falls deeper into danger from an abusive attendant and difficult inpatients. The latter include an arsonist and "The Champ," a lunatic ex-boxer who attacks anyone put into a room with him after he hears what sounds like a bell.

The title "Human Gorilla" for this movie can be found on various copies of this movie. Although the film features noir lighting and camerawork, depicts corruption, and provides suspense, it lacks most of the characterizations common to film noir. And it ends happily for the protagonists.
