The actress Ellay Mort is credited in the role of Chrystal Kingsby. This person does not exist. The credit is a joke, as the name is phonetic for the French phrase "elle est morte" or "she is dead."
Robert Montgomery's last MGM film. He had been under contract with the studio since 1929.
The entire movie plot unfolds from lead Robert Montgomery's point of view, thus creating a rarity in film: the principal character is never seen on-screen except as a reflection in mirrors and windows.
