20th Century-Fox's Western Union was loosely based on a story by Zane Grey. The basic historical facts behind the connecting of telegraph wires between Omaha and Salt Lake City serve as a backdrop for a fictional story straight out of
Manhattan Melodrama.
Randolph Scott and
Barton MacLane are cast as brothers who pursue wildly divergent paths in adulthood: Scott, an ex-outlaw, goes to work for Western Union, while MacLane remains a criminal, leading a concerted effort to sabotage the telegraph company. The Indians, too often merely villains in films of this nature, are treated with relative sympathy. When they do attack the whites, it is principally because they have been falsely accused of crimes committed by MacLane and his bunch. Western Union was the second Technicolor western effort from director
Fritz Lang; the first was the equally popular
Jesse James. ~ Hal Erickson, All Movie Guide
