Trivia, insights & behind the scenes
Fox insisted on Technicolor specifically to exploit Monroe's rising stardom—making this one of the only color noirs of the classic era.
The film's marketing essentially invented 'Marilyn Monroe, sex symbol'—her pink dress and red lipstick became instant iconography, overshadowing that she's playing an actual murderer.
