He became famous during the 1960s by directing several spaghetti westerns with such titles as Go Kill and Come Back (Vado... l'ammazzo e torno, 1967) , One Dollar Too Many (1968), Seven Winchesters for a Massacre (Sette winchester per un massacro, 1967) and Go Kill Everybody and Come Back Alone (Ammazzali tutti e torna solo, 1968).
