The Young Vito
Eight-year-old Vito Corleone, the lone survivor of a family cut down in a Sicilian vendetta, is smuggled into New York's Little Italy at the turn of the century.
When he reaches manhood, Vito (Robert De Niro) returns to Italy to avenge the murder of his family.
Back in New York, Vito works his way to the top of the organized-crime world. Feared and respected, Don Vito is known by all as the Godfather.

The Old Vito:
A Patriarch of crime
Aging Don Vito Corleone (Marlon Brando) rules his empire with the aid of his four sons: quick-tempered Sonny (James Caan), weak Fredo (John Cazale), Ivy League-educated Michael (Al Pacino) and adopted son
Tom Hagen (Robert Duvall).
Don Vito refuses to join the five ruling crime families in the narcotics trade, touching off a gang war.
