Buster Keaton "Francis". His father was Joseph Hallie "Joe" Keaton, who owned a traveling show with Harry Houdini called the Mohawk Indian Medicine Company, which performed on stage and sold patent medicine on the side. According to a frequently repeated story, which may be apocryphal, Keaton acquired the nickname "Buster" at about 18 months of age. Keaton told interviewer Fletcher Markle that Houdini was present one day when the young Keaton took a tumble down a long flight of stairs without injury. After the infant sat up and shook off his experience, Houdini remarked, "That was a real buster!" According to Keaton,
Buster Keaton a parody of D. W. Griffith's "Intolerance" (1916), from which it replicates the three inter-cut shorts structure. "Three Ages" also featured parodies of Bible stories, like those of Samson and Daniel. Keaton directed the film, along with Edward F. Cline. Film critic David Thomson later described Keaton's style of comedy: "Buster plainly is a man inclined towards a belief in nothing but mathematics and absurdity ... like a number that has always been searching for the right equation. Look at his face—as beautiful but as inhuman as a butterfly—and you see that utter failure to identify sentiment." Gilberto Perez commented
