Samuel Fuller’s 1982 masterpiece about American racismhis last work shot in this countryfocuses on the efforts of a black animal trainer (Paul Winfield) to deprogram a dog that has been trained to attack blacks. Very loosely adapted by Fuller and Curtis Hanson from a memoir by Romain Gary, and set in southern California on the fringes of the film industry, this heartbreakingly pessimistic yet tender story largely concentrates on tragic human fallibility from the vantage point of an animal; in this respect it’s like Robert Bresson’s Au Hasard Balthazar, and Fuller’s brilliantly eclectic direction gives it a nearly comparable intensity. Through a series of grotesque misunderstandings, this unambiguously antiracist movie was yanked from U.S. distribution partly because of charges of racism made by individuals and organizations who had never seen it. But it’s one of the key American films of the 80s. With Kristy McNichol, Burl Ives, Jameson Parker, and, in cameo roles, Dick Miller, Paul Bartel, Christa Lang, and Fuller himself. PG, 89 min. (JR)
