It's interesting how Pacino starred in three GF films, and by the third one, sounded like the original Vito Corleone, his screen father.
The singer Harry Belafonte played a character who was a hilarious charicature of Vito Corleone in the comedy film, "Uptown Saturday Night." Now his voice is shot to hell, just like Pacino's, and he sounds like Vito Corleone without even trying.
