The movie differs greatly from the
James M. Cain source novel. In the book, the male protagonist is John Howard Sharp, a professional opera singer who has lost his voice and fled the United States to Mexico in a crisis of confidence after being sexually wooed (not unsuccessfully, though details are vague) by a male socialite and impresario. Juana Montes is a Mexican prostitute who sees Sharp as gay and therefore a trouble-free partner to open a brothel with. But after having sex in a deserted church with Juana, Sharp recovers his voice and his preferred sexual identity. The two lovers come into conflict with the local police and flee to Los Angeles, where Sharp reestablishes his singing career, more successful than ever. But once they move to New York, the singer must struggle against the renewed blandishments of the gay impresario, whom Juana eventually murders with a torero's sword. As none of this material could be considered suitable for an American movie in 1956, the story's male impresario becomes female instead and the Mexican prostitute becomes a Mexican bullfighter's daughter. ==Production==
