Witness to Murder is a 1954 American film noir crime drama directed by Roy Rowland and starring Barbara Stanwyck, George Sanders, and Gary Merrill.
While the film received moderately positive reviews, it ended up as an also-ran to Alfred Hitchcock's somewhat similar Rear Window, which opened less than a month later.
[1] Cheryl Draper looks out of her bedroom window, and witnesses a young woman being strangled to death and reports it to the police, but when the killer, Albert Richter, sees detectives arriving downstairs, he moves the body.
She is forcibly admitted to an insane asylum after Albert surreptitiously types threatening letters from Cheryl to him to frame her as crazy and a threat to his safety.
After Cheryl is released, Lawrence and a fellow policeman go to the apartment building of the deceased woman (who was revealed to be a Miss Joyce Stewart) to see if anyone there recognizes Albert but no one does, and the police have no case.
His camerawork sets a dark mood of the Los Angeles scenario, escalating the dramatics with shadowy building shots.
"[5] Witness to Murder was featured on Lux Video Theatre in January 1956, starring Audrey Totter, Onslow Stevens and Paul Langton in the leading roles.
