Jerome Kern and Oscar Hammerstein II's immortal musical adaptation of Edna Ferber's sprawling novel receives it's most faithful and enduring cinematic adaptation under the elegant direction of James Whale. A rich portrait of changing American entertainment traditions and race relations, Show Boat spans four decades and three generations as it follows the fortunes of the stage-struck Magnolia (Irene Dunne), an aspiring actor whose journey takes her from her family's humble floating playhouse in the 1880s South to the height of fame in the 1930s North. The cast of show-business legends includes Helen Morgan, Hattie McDaniel, Charles Winninger, and the great Paul Robeson, whose iconic, soul-shaking rendition of Ol' Man River is one of the crowning glories of the American stage and screen.
