One of the best "psychological" westerns of the 1940s, RKO Radio's
Blood on the Moon
stars Robert Mitchum as itinerant cowboy Jim Garry. Riding into a Texas Indian reservation, Garry finds himself embroiled in a deadly feud between cattle ranchers and homesteaders. He befriends both Amy Lufton (Barbara Bel Geddes), daughter of wealthy cattle man John Lufton (Tom Tully), and smooth-talking mercenary Tate Rilling (Robert Preston). What neither Garry nor Amy realize is that Rilling is a snake, conspiring with crooked Indian agent Jake Pindalest (Frank Faylen) to make off with Lufton's cattle. At first aligning himself with Rilling, Garry finally figures out that his so-called friend is up to no good and casts his lot with Lufton, leading to a bloody showdown. Based on the novel by Luke Short,
was given top-grade treatment by director Robert Wise, an alumnus of RKO Radio's editing department.
