Buster Keaton and Donald O’Connor on the set of The Buster Keaton Story (1957). Keaton was hired as a technical consultant to coach O’Connor on how to recreate many of Keaton’s famous gags, but O’Connor, despite his best efforts, didn’t quite cut the mustard. As Keaton biographer Tom Dardis said, “O’Connor tried hard, but it was impossible for anyone to portray Keaton’s movements.” In the end, Keaton was embarrassed by the biopic, mostly due to its inaccuracy. Keaton’s wife, Eleanor later said that after seeing it for the first time at the premiere, “My stomach turned over, it was so awful!”
All was not lost. Keaton was paid $60,000 for the rights to his life story, which enabled him to buy a house at 22612 Sylvan Street in Woodland Hills.
