In one of his biggest box-office hits, Errol Flynn portrays dapper James C. Corbett, whose style in and out of the ring helped bring acceptability to what had been an unsanctioned, back-room sport. The role was a Flynn favorite, and he rigorously schooled himself in the gliding footwork, deft jabbing, feinting and left-hooking that were Corbett trademarks. Raoul Walsh, director of seven Flynn films, balances bravura fisticuffs with family vignettes and flirtatious romance (Alexis Smith is Flynn%u2019s co-star). And Ward Bond plays heavyweight champ, John L. Sullivan, a legendary ring king dethroned by the clever but tough GENTLEMEN JIM.
