Adapted from a novel by Louis L'Amour, Stranger on Horseback is one of Joel McCrea's shorter western vehicles, zipping merrily along at a mere 66 minutes. McCrea plays a travelling judge who makes it his mission in life to clean up the town of Bannerman. This proves difficult, in that the town is virtually owned by the Bannerman family. But when the family's youngest son (Kevin McCarthy) commits murder, McCrea vows to bring the boy to justice -- and to see that he gets a fair trial, despite pressure from the Bannermans' enemies. Czech-Mexican actress Miroslava makes one of her rare American film appearances as McCrea's love interest; shortly after Stranger on Horseback was released, Miroslava committed suicide, allegedly as a result of an unhappy romance with bullfighter Luis Miguel Dominguin.
