Few actors can boast a filmography as extensive as the John Wayne; the quintessential Golden Age of Hollywood actor, Wayne was a prolific performer who appeared in dozens of classic films, establishing himself as one of the most recognizable leading men in cinema history. With a particular specialty for starring in Westerns, Wayne defined the image of a Hollywood cowboy as he helped bolster the success of the genre, which was at its most lucrative in the early 20th century. Wayne's popularity was ubiquitous, and in the late 1930s he starred in arguably the largest Western franchise of the time, The Three Mesquiteers — a series of movies with over 4 dozen installments, easily dwarfing even the exhaustive Marvel Cinematic Universe. Though The Three Mesquiteers aren't the household names they once were, their legacy as one of the largest film franchises continues to be felt in the genre, and in cinema, today.
