Shooting began on July 15, 1927, in Sacramento. Production was delayed when Keaton broke his nose in a baseball game. The film includes his most famous stunt: an entire building facade collapsing all around him. The open attic window fits neatly around Keaton's body as it falls, coming within inches of flattening him. He had performed a similar, though less elaborate, stunt in his earlier short films "Back Stage" (1919) and "One Week" (1920). He used a genuine, two-ton building facade and no trickery. The mark on the ground showing Keaton exactly where to stand to avoid being crushed was a nail. It has been claimed that if he had stood just inches off the correct spot, he would have been seriously injured or killed. His third wife, Eleanor, suggested that he took such risks due to despair over financial problems, his failing first marriage, the imminent loss of his filmmaking independence, and recklessness due to his worsening alcohol abuse at the time. Evidence that Keaton was suicidal, is scant—he was known throughout his career for performing dangerous stunts independent of any difficulties in his personal life, including a fall from a railroad water tower tube in 1924's "Sherlock Jr." in which his neck was fractured. He later said, "I was mad at the time, or I would never have done the thing." He also said that filming the shot was one of his greatest thrills.
