This was the final Marx Brothers film. Groucho appears without his usual greasepaint moustache and thick eyebrows. He is rarely in the same scenes as his brothers (the three are never seen together), and mainly provides an encompassing narration to explain things in the film when the necessary sequences for a coherent narrative were unavailable. A group of aspiring actors are putting together a musical revue called Love Happy. Harpo, the troupe's mascot, keeps the actors from starving by stealing canned goods from a local grocer. On one occasion, he accidentally grabs a sardine can containing the stolen Romanoff diamonds. As a result, Harpo becomes the target of adventuress Madame Egilichi (Ilona Massey) and her stooges (Melville Cooper, Raymond Burr, Bruce Gordon).
