Buster Keaton was one Badass Stunts Master

Buster Keaton was one of the best Vaudeville actors/stuntmen of his time. Filming his iconic house falling shot in Steamboat Bill Jr. required precision, because the prop house weighed two tons, and the window only offered a few inches of clearance around Keaton’s body.
Before filming it, the crew threatened to walk off the set and the cameraman looked away while rolling it. The heavy prop brushes his arm as it comes down, and he doesn’t flinch.
The sequence became the most memorable image of his career.
