Grey's serialized novel, published in
Ladies’ Home Journal in 1922–1923, was one of the first pieces of literature produced which offered a harsh portrayal of American government policies towards Native Americans. Grey depicted the white settlers as missionaries who preyed upon the subordinate race, forcefully converting them into Christianity and altering their way of life. This depiction sparked a lot of backlash in the form of angry letters from readers once the novels were published. According to
Zane Grey's biographer, Thomas Pauly, “The magazine was deluged with angry letters from religious groups, and the Bureau of Indian Affairs vehemently denounced his depiction of their efforts.” In response to critics of the novel, Lasky persuaded Grey to dilute the negative portrayal of the American government in the film. Grey agreed, and instead of Americans monolithically demonstrating contempt towards Native Americans, the script instead placed most of the blame on the corrupt choices of an individual character, Booker. According to an interview with Lasky in September 1925, the idea for adapting Grey's novel into a feature film originated in 1922 when he and
Lucien Hubbard, the editorial supervisor for Zane Grey Productions, received an invitation from Grey to visit Navajo Mountain and Rainbow Bridge in northern Arizona. The reservation's stark and boundless desert scenery captivated Lasky and after spending nearly two months there, he suggested they use the vast ranges as the background for a motion picture. ==Plot==
