Question: What American archbishop is a main antagonist in  "The Godfather Part III" said to have been based on?
Context: John Holland Cazale ( ; ] ; August 12, 1935 – March 13, 1978) was an American actor.  He appeared in five films over a period of six years, all of which were nominated for the Academy Award for Best Picture: "The Godfather", "The Conversation", "The Godfather Part II", "Dog Day Afternoon", and "The Deer Hunter."  He appeared in archival footage in "The Godfather Part III", also nominated for Best Picture, making him the only actor to have this multi-film distinction.  From his start as a theater actor, he became one of Hollywood's premier character actors, starting with his role as the doomed, weak-minded Fredo Corleone opposite longtime friend Al Pacino in Francis Ford Coppola's film "The Godfather" and its 1974 sequel.  Cazale chose to continue acting despite being diagnosed with lung cancer.  He died in New York City on March 13, 1978, shortly after completing his role in "The Deer Hunter". The Godfather Saga is a TV miniseries that combines "The Godfather" and "The Godfather Part II" into one film.  It originally aired on NBC over four consecutive nights (one three-hour segment and three two-hour segments) in November 1977.  "The Godfather Saga" is also known as The Godfather: The Complete Novel for Television, The Godfather: A Novel for Television, The Godfather Novella, and The Godfather Epic (on HBO).  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. Lucy Mancini is a fictional character in Mario Puzo's "The Godfather".  She was portrayed by Jeannie Linero in "The Godfather" and "The Godfather Part III". Archbishop Gilday is a fictional character and one of the main antagonists in "The Godfather Part III".  He is portrayed by Donal Donnelly.  His character is said to have been based on Paul Marcinkus. The Godfather Part III is a 1990 American crime film written by Mario Puzo and Francis Ford Coppola, and directed by Coppola.  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. Paul Marcinkus ( ), GCOIH (January 15, 1922 – February 20, 2006) was an American archbishop of the Roman Catholic Church.  He was best known for his tenure as President of the Vatican Bank from 1971 to 1989. Carmine Coppola (June 11, 1910 – April 26, 1991) was an American composer, flautist, editor, musical director, and songwriter who contributed original music to "The Godfather", "The Godfather Part II", "Apocalypse Now", and "The Godfather Part III", all directed by his son Francis Ford Coppola. "G.O.D. Pt.  III" is the third single from Mobb Deep's "Hell on Earth" album.  The song contains an interpolation from "Tony's Theme" by Giorgio Moroder from the 1983 film "Scarface", and a drum-loop from "Fool Yourself" by Little Feat.  The title is a reference to "The Godfather Part III".  The chorus features Infamous Mobb member Godfather Pt.  III. Vincent Santino Corleone (né Mancini) is a fictional character in the 1990 feature film "The Godfather Part III", in which he is portrayed by Andy García, who was nominated for an Academy Award for his performance.  Vincent is the illegitimate son of Sonny Corleone and his mistress Lucy Mancini.  He eventually succeeds his uncle Michael as head of the Corleone family.  Retroactive continuity ("retcon") was employed to create the character's existence for "The Godfather Part III", as it is evident from Mario Puzo's original novel that Lucy did not conceive a child with Sonny. Barry M. Malkin (born October 26, 1938) is an American film editor with about 30 film credits.  He is noted for his extended collaboration with director Francis Ford Coppola, having edited most of Coppola's films from 1969-1997.  In particular, Malkin worked with Coppola on four of the component and compilation films of the "Godfather Trilogy", although he was not involved in the original 1972 film.  Roger Ebert has written of "The Godfather Part II", which Malkin edited, "... why is it a "great movie"?  Because it must be seen as a piece with the unqualified greatness of "The Godfather."  The two can hardly be considered apart ("Part III" is another matter).  When the characters in a film take on a virtual reality for us, when a character in another film made 30 years later can say "The Godfather" contains all the lessons in life you need to know, when an audience understands why that statement could be made, a film has become a cultural bedrock."
