The phrase “The Godfather Trilogy 1901–1980” originally appeared on a 1992 home video box set (VHS and laserdisc) presenting the films in chronological order. It is not a separate official release. No legal download is available for that specific edit, but the same material is accessible via the legal sources above.
The Godfather Part II (1901–1925): This installment serves as both a prequel and a sequel. It opens in 1901, following young Vito Andolini as he escapes Sicily for New York City. We witness his transformation into the respected and feared Don Vito Corleone, masterfully played by Robert De Niro. Parallel to this, we see Michael Corleone (Al Pacino) in the 1950s, struggling to maintain his grip on the family business.
