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 (unlike The Saphead, in which he only acted), 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.
