Three Ages is a 1923 black-and-white American feature-length silent comedy film starring comedian Buster Keaton and Wallace Beery. The first feature Keaton wrote, directed, produced, and starred in, Keaton structured the film like three inter-cut short films. While Keaton was a proven success in the short film medium, he had yet to prove himself as a feature-length star. Had the project flopped, the film would have been broken into three short films, each covering one of the ages. The structure also worked as a parody of D. W. Griffith's 1916 film Intolerance.
