Los comancheros

...was this rousing action western starring John Wayne, who also directed many scenes uncredited when the ailing Curtiz was too ill to shoot.

It's a pretty good western overall, not terribly original or up to the best of the genre, but certainly a solid, entertaining production with a veteran cast and few good action sequences that should please most Western fans and Wayne fans. In his typical and well-loved manner, Wayne plays Jake Cutter, a Texas Ranger trying to bring in a charming gambler charged with murder after a fatal duel, and also to deal with a band of outlaws who are trading in guns and whisky with the hostile Comanche Indians. Stuart Whitman plays the gambler, who meanwhile has fallen for a mysterious and independent-minded beauty he met before being arrested (Ina Balin), and later discovers she's the daughter of the ruthless head of the Comancheros (Nehemiah Persoff).

There are brief but memorable roles played by Lee Marvin, Bruce Cabot, Edgar Buchanan, Henry Daniell, and even Guinn "Big Boy" Williams, among others.
