Trivia
Was about to start filming with rising star Robert Williams in the role of Guy when Williams died from a sudden attack of appendicitis and peritonitis. Ben Lyon replaced him in the role.
About 12 minutes into the film, Constance mentions to the host that her drink is strong. When the host offers to taste it, she hands him a glass that has less liquid than when it cuts to him tasting the cocktail.
