The Joe Louis Story (1953)
After a brief allusion to Golden Boy, this moves meticulously into the training of a great boxer, and good clips from his bouts with Primo Carnera, Max Baer (Louis in terrific, workmanlike fighting), Max Schmeling (Louis out of shape and overmatched), the champion Braddock, Schmeling again (Louis in precision), plus footage of the 1942 "Night of Stars" at the Garden, and Louis's WWII tour, ending with his final fight with Rocky Marciano (Louis out in harness).
