Rivero's most notorious role came in "The Sin of Adam and Eve" (El pecado de Adán y Eva) (1969), in which Rivero and American costar Candy Wilson appear nude throughout most of the film. By 1970, Rivero had offers from Hollywood and acted in the big-budget films "Soldier Blue" (1970; with Candice Bergen and Donald Pleasence), "Rio Lobo" (1970; with John Wayne and Jennifer O'Neill) and "The Last Hard Men" (1976; with Charlton Heston and James Coburn). Afterward, Rivero continued to act in Mexican, Italian and U.S. productions, including appearances in Lucio Fulci's 1983 fantasy film "Conquest", and the all-star action film "Counterforce" in 1988.
