St. Louis Blues is a 1939 American musical film distributed by Columbia Pictures and directed by Raoul Walsh. It is set on a Mississippi River showboat where a Broadway musical comedy star who has tired of the same old grind winds up, on which she the showboat's skipper and they make plans to put together a musical revue. Though the song "St. Louis Blues" is performed, the film's plot is not based on the song. Artists appearing in the film include jazz singer Maxine Sullivan and composer/singer/actor Hoagy Carmichael. The film stars Dorothy Lamour, Lloyd Nolan, Tito Guízar, Jerome Cowan and Mary Parker. Lamour sings "I Go for That" by Matt Malneck, Jr. and Frank Loesser in the film, and it became a hit recording.
