This took guts

[Buster] Keaton’s most famous gag occurred in Steamboat Bill, Jr., in which he stands in front of a house during a cyclone. The facade of the house falls on top of him & he survives because he happens to be standing exactly where the attic window falls. Keaton refused to rehearse the stunt before shooting the scene because, as he explained, he trusted his set-up, so why waste a wall?
