Trivia: Director Alfred Hitchcock has a cameo role in this film - he is seen getting a glass of champagne from the bartender at the party in Alexander Sebastian's mansion.
Continuity mistake: Devlin walks in Huberman's place, and she is lying on the couch with a glass of milk right in front of her eyes. The angle of the camera is skewed to show her POV, but the glass of milk has vanished.
