Love Happy

Love Happy is a 1949 American musical comedy film, released by United Artists, directed by David Miller and starring the Marx Brothers (Groucho Marx, Harpo Marx and Chico Marx) in their 13th and final feature film, as well as a memorable walk-on by a relatively unknown Marilyn Monroe. The film, produced by former silent film star Mary Pickford, features Groucho Marx in a smaller role than usual, with a supporting cast including Ilona Massey, Vera-Ellen, Paul Valentine, Marion Hutton, Raymond Burr, Bruce Gordon (in his film debut), Eric Blore, and Marilyn Monroe in the aforementioned sequence with Groucho. The plot was written by Frank Tashlin and Mac Benoff, based on a story by Harpo. Plot Private detective Sam Grunion has been searching for the extremely valuable Royal Romanoff diamonds for eleven years, and his investigation leads him to a troupe of struggling performers, led by Mike Johnson, who are trying to put on a musical revue called Love Happy.
