Groucho Marx made his first solo film appearance away from his brothers in the musical comedy Copacabana. Groucho plays two-bit theatrical agent Lionel Q. Devereaux, whose favorite client--indeed, his only client--is fireball Brazilian entertainer Carmen Novarro (Carmen Miranda). Hoping for a double commission, Devereaux gets Carmen two different singing jobs at the Copacabana nightclub, through the simple expedient of having Carmen wear a veil and pose as a French chanteuse. Steve Hunt (Steve Cochran), manager of the Copa, falls in love with one of the Carmens, much to the dismay of pretty bookkeeper Anne (Gloria Jean).
