Saw this movie as a kid, watching " The Late Show, " which was always a great old b/w movie. Years later, read about the murder of William Desmond Taylor and thought this hit awfully close to home. Taylor was a director of some note in early Hollywood, but also known to be quite the ladies' man. He was murdered in his apartment and the case was never officially solved. After his murder, the career of Mary Miles Minter, a well known Hollywood starlet was pretty much in ruins, due to several pieces of her personal belongings found at the scene of the crime, which is interesting, as studio bigwigs were called to the apartment before the police were called. Also interesting was the rumor that his now missing valet / butler / chauffeur was in reality his brother. The deceased Tayor was not who he appeared to be - he had long before abandoned a wife and child and re-invented himself. Years later, the famed Hollywood director King Vidor became interested in the mystery and worked on it for some years. His efforts were detailed in a book called " A Cast Of Killers, " well worth the read.
