Based on the best-selling book written by Mario Puzo, The Godfather was released in 1972 to overwhelming critical acclaim and successful box office performance. Directed by Francis Ford Coppola, The Godfather focuses on the Corleone mafia crime family led by patriarch Don Vito Corleone (Marlon Brando). When Vito is wounded during an assassination attempt, his youngest son Michael (Al Pacino) becomes the new Don of the Corleone clan, proving to be even more cunning and ruthless than his father. Over the last 50 years, The Godfather has gone on to be praised as one of the greatest films of all time, a crime classic that is often mimicked but never beaten.

With a new home entertainment release on the horizon in celebration of the film's 50th anniversary, as well as the new Paramount+ series The Offer presenting a dramatization of the making of The Godfather, here is a cast and character guide for one of the greatest movies of all time.

The youngest son of the Corleone family and a veteran of WWII, Michael would become the eventual successor to his father Vito.

Although he was not fully integrated into the Corleone mafia family due to his Irish blood, Hagen nevertheless played a vital role in the success of the Corleones.

A loyal captain to the Corleone crime family, Peter Clemenza proves to be a key character in the Godfather story. This is especially seen in a vital plot point when Clemenza instructs Michael on how to execute a man, leading to the now infamous “Sollozzo scene” in which Michael slays a drug kingpin and a corrupt police officer.

The role of Clemenza led to an Oscar nomination for Richard S. Castellano, a long-time New York-based character actor. Unfortunately, a falling out with director Francis Ford Coppola resulted in Castellano not reprising his character in The Godfather Part II.

John Cazale as Fredo Corleone

The second son of Vito Corleone, Fredo developed a reputation as the weaker and less intelligent of the Corleone brothers. This in turn led to a bitterness on his part that had drastic consequences.
