 A sequel to "The Godfather" (1972) and "The Godfather Part II" (1974), it completes the story of Michael Corleone, a Mafia kingpin who attempts to legitimize his criminal empire.
 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.

 The television version was the basis for a shorter, 1981 video release known as The Godfather 1902–1959: The Complete Epic.
 Following the release of "The Godfather Part III" in 1990, a third unified version was released to video in 1992 entitled The Godfather Trilogy: 1901–1980.

 Subplots include Nick Geraci's plans for revenge against the Corleones, Tom Hagen's being implicated in a murder, and organized crime's battle with a presidential family (the Sheas, who are analogous to the Kennedy family).
