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 (1920), in which he only acted), Keaton structured the film like three inter-cut short films. The structure also worked as a satire of D. W. Griffith's 1916 film Intolerance. The film was shot in this manner as a kind of insurance for the studio.
