With 14 films together, John Ford and John Wayne may be the most famous director-actor duo in American film history, from 1939's "Stagecoach" to 1963's "Donovan's Reef." Other films discussed are "She Wore a Yellow Ribbon," "The Quiet Man," "The Searchers," and "The Man Who Shot Liberty Valance." Although each made over 100 films, it's arguably these that defined their respective careers.
