One Night in the Tropics (1940) is not a typical Abbott and Costello film but rather a musical comedy that marks the screen debut of the famous comedic duo, Bud Abbott and Lou Costello. Set against the backdrop of a lush tropical resort, the film focuses primarily on the romantic entanglements and business dealings of Jim “Lucky” Moore (played by Allan Jones), an insurance salesman who comes up with an unusual scheme involving “love insurance” to ensure his own romantic success.

Abbott and Costello play secondary roles as Roscoe and Costello, respectively, friends of Lucky and part of the comic relief that supports the main storyline. Their bits of business, however, steal the show, giving audiences their first taste of the duo’s impeccable timing and classic routines, including a precursor to their famous “Who’s on First?” sketch.

The plot revolves around Lucky trying to ensure his marriage goes ahead by selling an insurance policy to his friend, Tommy Grayson (played by Robert Cummings), that would pay out if Tommy’s fiancée, Cynthia Merrick (played by Nancy Kelly), doesn’t marry him. Complications arise when Tommy actually falls for another woman, Mickey Fitzgerald (played by Peggy Moran), leading to a series of misunderstandings, mistaken identities, and romantic misadventures.

While the film’s narrative focuses on romance and musical numbers, Abbott and Costello’s comedic interludes highlight their dynamic and foreshadow the successful career they would have in cinema. Their scenes are filled with the rapid-fire dialogue and slapstick humor that would become their trademark.

“One Night in the Tropics” is celebrated not only for its historical significance as the duo’s film debut but also for its blend of music, romance, and comedy, setting the stage for Abbott and Costello’s rise to fame.
