The Spaghetti Western achieved popularity in the mid-1960s, peaking with Sergio Leone's Dollars Trilogy, which featured enigmatic scores by composer Ennio Morricone, which have become popular culture icons of the Western genre. Erotic Italian thrillers, or "giallos", produced by directors such as Mario Bava and Dario Argento in the 1970s, influenced the horror genre worldwide. During the 1980s and 1990s, directors such as Ermanno Olmi, Bernardo Bertolucci, Giuseppe Tornatore, Gabriele Salvatores and Roberto Benigni brought critical acclaim back to Italian cinema.
