 Bertolucci increased his fame with his next few films, from "1900" (1976), an epic depiction of the struggles of farmers in Emilia-Romagna from the beginning of the 20th century up to World War II with an international cast (Robert De Niro, Gérard Depardieu, Donald Sutherland, Sterling Hayden, Burt Lancaster, Dominique Sanda) to "La Luna", set in Rome and in Emilia-Romagna, in which Bertolucci deals with the thorny issue of drugs and incest, and finally "La tragedia di un uomo ridicolo" (1981), with Ugo Tognazzi.He then wrote two screenplays based on Dashiell Hammett’s Red Harvest.He hoped this would be his first film set in America, but nothing came of it.
