John Wayne is a Texas Ranger in this rollicking, good humored western, assigned to bring an arms-running gang to justice. After Wayne arrests one of the criminals, matters are complicated when they wander into an area controlled by the Comancheros: a group of Anglos aiding the warring Comanche Indians. Based on the novel by Paul I. Wellman, THE COMANCHEROS was the last film for director Michael Curtiz (CASABLANCA).
