The Spoilers (1942, Ray Enright)

A not-too-exciting Marlene Dietrich/John Wayne western. Boring ol’ Randolph Scott (Roberta, Ride Lonesome) rides into town claiming to represent the law of the country but really planning to steal land from local miners. John Wayne is seduced by Scott’s uneasy companion Margaret Lindsay (Jezebel, Fog Over Frisco) until he catches onto their scheme. Dietrich is wise from the beginning. She and third-wheel Richard Barthelmess (that guy from Only Angels Have Wings who looks like a cross between Buster Keaton and Peter Lorre) help Wayne foil the plan, and the mines are saved, yay.

But most notably: John Wayne in blackface!
