1933 was a strange year for New York on film. When a giant ape wasn't climbing the Empire State Building in King Kong, a massive earthquake was shaking the city's skyscrapers to the ground in Deluge. Watch how New York City met its doom long before Roland Emmerich knocked down his first Lincoln Log cabin.
Directed by Felix E. Feist, Deluge was once thought to be lost until an Italian dub of the film turned up in the 1980s. The disaster sequence, however, had been kept as stock footage and re-used for the 1939 film S.O.S. Tidal Wave, 1941's Dick Tracy vs. Crime, Inc., and 1949's King of the Rocket Men.
And You Call Yourself a Scientist has a fantastic, detailed synopsis and history of the film.
