1946 film by Alfred E. Green
The Jolson Story is a 1946 American biographical musical film, a highly fictionalized account of the life of singer Al Jolson, produced by Columbia Pictures and directed by Alfred E. Green. It stars Larry Parks as Jolson, Evelyn Keyes as Julie Benson (approximating Jolson's wife, Ruby Keeler), William Demarest as his performing partner and manager, Ludwig Donath and Tamara Shayne as his parents, and Scotty Beckett as the young Jolson. Some of the film's episodes are based on fact but the story is extremely simplified, with people disguised or combined into single characters.
