Possibly the greatest movie musical of all, this 1936 version of Showboat has Irene Dunne, Allan Jones, Paul Robeson and Hattie McDaniel joining Helen Morgan and Charles Winninger from the original Broadway cast of 1927. So great that, when MGM made their own version in 1951, they tried to have all prints and copies of the original destroyed. Mercifully they weren't quite successful. Closer to the original stage version, this includes most of the classic songs by Jerome Kern and Oscar Hammerstein, not least Robeson singing Ol' Man River. Terrific!
