Originally titled It Ain't No Sin until the censors prevailed, then St. Louis Woman and Belle of New Orleans, until complaints were registered from those two communities, Belle of the Nineties was Mae West's first post-Production Code film. West is cast as cabaret entertainer Ruby Carter, plying her trade along the Mississippi. Having no trouble surviving on her own terms in a man's world, Ruby fends off the unwarranted attentions of a steady stream of libidinous males, reserving her affections for a muscular boxer called The Tiger Kid (Roger Pryor). In keeping with the star's casual liberality, a number of black entertainers and athletes are given ample opportunities in this film, notably Duke Ellington and His Orchestra. The surest sign that the Code had "tamed" West a bit is the fact that she actually marries the hero at film's end. The musical highlights include West's unforgettable rendition of "My Old Flame."
