Pre-production
Although they were close friends, Ford declined to use Wayne in any of his projects during the 1930s, telling him to wait until he was "ready" as an actor. In 1938, Ford gave Wayne a copy of the film's script by Nichols with a request to recommend an actor to play the Ringo Kid. After reading it, Wayne suggested Lloyd Nolan for the part, but Ford was non-committal to the idea. The next day however, Ford announced to Wayne that he wanted him to play the role. The offer left Wayne feeling as if he had been "hit in the belly with a baseball bat" ... and fearing that Ford would change his mind and hire Nolan instead.
Before production, John Ford shopped the project around to several Hollywood studios, all of which turned him down because big budget Westerns were out of vogue, and because Ford insisted on using John Wayne in a key role in the film. Wayne previously appeared in only one big-budget western, The Big Trail (1930, directed by Raoul Walsh), which was a huge box office flop. Between 1930–1939, by Wayne's own estimate, he appeared in about eighty "Poverty Row" westerns. Independent producer David O. Selznick finally agreed to produce the film, but was frustrated by Ford's indecision about when shooting would begin, and his own doubts over the casting. Ford withdrew the film from Selznick's company and approached independent producer Walter Wanger about the project. Wanger had the same reservations about producing an "A" western and even more about one starring John Wayne. Ford had not directed a western since the silent days, the most notable of which had been The Iron Horse (1924). Wanger said he would not risk his money unless Ford replaced John Wayne with Gary Cooper and brought in Marlene Dietrich to play Dallas.
Ford refused to budge; it would be Wayne or no one. Eventually they compromised, with Wanger putting up $250,000, a little more than half of what Ford had been seeking, and Ford would give top billing to Claire Trevor, a more well-known name than John Wayne in 1939.
