Godfather 1 was set in early forties where micheal corleone would have been around 19. Godfather 3 is set in 1979. Almost 40 years later. The Pacino character is supposed to be 60 years old. Pacino wasn't 60 in 1987 so they made him look older by greying his hair and giving him some temple recession. And in Heat you are looking at his real hair not some wig. Wigs back then looked like sh*t. No friggin way he's wearing.
