 The scenes of crew members on the ship struggling in the violent storm were lifted from a Universal silent film, "The Storm Breaker" (1925).Photographed at silent film projection speed, this accounts for the jerky, sped-up appearance of the footage when projected at 24 frames per second sound film speed and cobbled together with new footage of Dracula and Renfield.Jack Foley was the foley artist who produced the sound effects.
