The film also includes fictionalized accounts of two real-life events : the 1978 death of Pope John Paul I and the Papal banking scandal of 1981 -- 82 , both linked to Michael Corleone 's business affairs . The film stars Al Pacino , Diane Keaton , Talia Shire , and Andy García , and features Eli Wallach , Joe Mantegna , George Hamilton , Bridget Fonda , and Sofia Coppola .
