For over twenty years John Ford and John Wayne were a blockbuster Hollywood team, turning out many of the finest Western films ever made. Ford, a son of Irish immigrants known for his black eye patch and for his hard-drinking, brawling masculinity, was renowned for both his craftsmanship and his brutality. John "Duke" Wayne was a mere stagehand and bit player in "B" Westerns, but he was strapping and incredibly handsome, and Ford saw his potential. In 1939 Ford made Wayne a star in Stagecoach, and from there the two men established a close, often turbulent relationship. Their most productive years saw the release of one iconic film after another- Rio Grande, The Quiet Man, The Searchers, She Wore a Yellow Ribbon, The Man Who Shot Liberty Valence. But by 1960, the bond of their friendship had frayed, and Wayne felt he could move beyond his mentor with his first solo project, The Alamo. Few of Wayne's following films would have the brilliance or the cachet of a John Ford Western but, taken collectively, the careers of these two men changed movie making in ways that endure to this day. Despite the decline of the Western in contemporary cinema, its cultural legacy, particularly the type of hero codified by Ford and Wayne-tough, self-reliant, and unafraid to fight but also honorable, trustworthy, and kind-resonates in everything from Star Wars to today's superhero franchises. Drawing on previously untapped caches of letters and personal documents, Nancy Schoenberger dramatically narrates a complicated, poignant, and iconic friendship, and the lasting legacy of that friendship on American culture.
