Buster Keaton had practically grown up on the stage. At three, the son of the owner of a traveling show along with the magician Harry Houdini, joined his father in a skit which had him disobeying his dad, only to be physically tossed around for his insubordination. Occasionally, Joe, his dad, was arrested for child abuse after the show. But young Keaton showed authorities his body sustained no bruises despite tossed into the scenery, the orchestra pit and even into the audience. The young boy learned how to fall. "The secret is in landing limp and breaking the fall with a foot or a hand," Keaton later said. "It's a knack. I started so young that landing right is second nature with me. Several times I'd have been killed if I hadn't been able to land like a cat. Imitators of our act don't last long, because they can't stand the treatment."
Buster was having such a good time getting thrown around he would giggle after he landed, causing the audience to become silent. He saw if he possessed a deadpan face after the stunts, the theatergoers howled in laughter. Transporting that trait onto film, he earned the nickname "The Great Stone Face."
It's a rarity Keaton was caught smiling in film. One of the few times he does appears in his third movie with Fatty, Aug. 1917's "His Wedding Night." Keaton plays a delivery boy bringing Fatty's fiancee, Alice, her wedding dress. Alice asks Buster to try it on to see if she likes it. He does, and he emerges from behind a partition smiling.
In a scene earlier in the movie, when a luxurious car pulls up to Fatty's outdoor gas pump, seen in the back seat are two women. One was Natalie Talmadge of the famous acting Talmadge sisters, who later were owners of their own studio. Natalie worked for Fatty as a script girl/secretary when she met Keaton. The two later fell in love, married, and had two children.
