The Godfather

Before his death, Marlon Brando recorded a small amount of dialogue to reprise his character, Don Vito Corleone. He was very enthusiastic about this work, was fascinated with the technology involved, and approved of his character's representation in the game. Unfortunately, due to his poor health only one of his recordings made it into the game. The oxygen tank he needed to breathe was audible on the track. The only scene that actually uses Brando's voice was the scene in the hospital. When you approach Don Vito in his hospital bed, he gives a short speech about Sollozzo. Clips of Brando's voice taken from the film are used in some scenes. Doug Abrahams, who also voiced Clemenza and Jack Woltz in the game, was cast specifically for his ability to mimic Brando, and also acted as a dialect coach.

Peter Clemenza does not age nor change his clothes in nearly 20 years (1936-1955).
