The Western has been a popular genre of cinema since the very beginning of film, and successive generations of filmmakers have used the “Wild West” as a backdrop on which to explore the social issues of their respective eras. Many of the early silent films at the beginning of the 20th century were Westerns, the most famous being 1903’s The Great Train Robbery.. During the 1920s, the Western film genre produced some of Hollywood’s first megastars such as Tom Mix and William S. Hart. These early Westerns were heavy on action, but light on plot. Their primary goal was to simply entertain.
