Clark Gable went from supporting actor to star in the space of one year with Sporting Blood, adapted from a novel by Frederick Hazlitt Brennan. Gable is top-billed as a gambling house proprietor named Rid Riddell. When the owner of a prize thoroughbred loses heavily in Riddell's establishment, he is forced to give up the horse to the gambler as security. Rid enters the horse in several honest races, then pulls the animal during a crucial race in order to collect big money on the losses; then he plans to dope up the horse to assure future wins. But when the horse loses, the gambler, deeply in debt to mobsters, transfers ownership to one of his female dealers (Madge Evans), and then drops out of the plotline. Clark Gable isn't really the lead in Sporting Blood--actually he's something of a rat--but he's the one whom everybody in the audience remembers long after the final fadeout.
