My Favorite Brunette is a 1947 movie spoofing movie detectives and the film noir style. The film stars Bob Hope as a photographer who dreams about being a real private detective like his friend Sam McCloud (Alan Ladd). One day while at McCloud's office he is mistaken for a detective by a mysterious lady in distress (Dorothy Lamour) and soon finds himself involved in a murder mystery.

After being implicated as a murderer, Hope devises a plan to clear his name by making a secret recording of his accusers telling the truth. He succeeds, but before the cops can hear the recorded admission, the record is switched out for another: Betty Hutton's rendering of "Murder, He Says".
