Amiable and exceptional character actor Billy Green Bush appeared in a handful of offbeat and enduring cult classic features made in the early '70s. Tall, handsome and rangy, Bush often portrayed engaging good ol' boy types, rugged cowboys and stern police officers. He was born as William Warren Bush in 1935. Billy was terrific as lazy hillbilly oil rig worker Elton in Bob Rafelson's wonderful Five Easy Pieces - Ein Mann sucht sich selbst (1970). He was likewise excellent as cop Robert Blake's affably dimwitted partner Zipper in the splendid Harley Davidson 344 (1973). Bush gave another outstanding performance as tough-as-nails trail boss Frank Culpepper in the superbly gritty Western Greenhorn (1972). Other memorable roles include a hard-nosed sheriff in Ein mörderisches Team (1971), no-nonsense Warden Earl Gulliver in the powerful made-for-TV movie Ein Mann kämpft allein (1979), gruff state trooper Donner in Hitcher - Der Highway Killer (1986), and resolute farmer Jay Brown in the immensely enjoyable creature feature Critters - Sie sind da! (1986). Among the TV shows Bush has done guest spots on are Polizeirevier Hill Street (1981), Das A-Team (1983), CHiPs (1977), Der unglaubliche Hulk (1977), Ein Duke kommt selten allein (1979), Starsky und Hutch (1975), Baretta (1975), M*A*S*H (1972), Rauchende Colts (1955), Los Angeles 1937 (1971), Bonanza (1959), The Outer Limits (1963), and Renegade - Gnadenlose Jagd (1992). Bush also played the sheriff in the ninth installment of the slasher series, 'Friday the 13th', entitled Jason goes to Hell - Die Endabrechnung (1993). He has since retired from acting. Billy is the father of actor Clay Greenbush and twin actresses Sidney Greenbush and Rachel Lindsay Greenbush.
