The Salaries
Fans were shocked to see that Al Pacino, James Caan, and Diane Keaton were all paid $35,000 for their time on the film. Inflation makes a difference, yes, but that's still totally low!
The Corleone Name
The last name of Corleone actually means something in Italian! It's roughly translated to "lionheart." After seeing these films, it's hard to argue that.
