During the years preceeding his death, Sonbert channeled his energy into making Whiplash. His vision and motor skills impaired, he gave his companion, Ascension Serrano, detailed instructions about the assembly of specific shots and the music to be used as a counterpoint to the images. Before his death in 1995, he asked filmmaker Jeff Scher (a former student of Sonbert's at Bard) to complete the film. --Jon Gartenberg
