The Punch
This scene was huge. They had to hire over 700 extras for this scene and it took four days to film. Somehow, nobody noticed that James Caan's punch was a complete miss and looked absolutely awful. What were they thinking?
Bitter Pacino
Marlon Brando wasn't the only Godfather actor to avoid the 1973 Academy Awards. Al Pacino opted to forgo the awards ceremony, too, but for totally different reasons. He was one of the three cast members to earn the Best Supporting Actor nomination, but he thought that he deserved better. In fact, he thought he deserved the Best Actor nomination. So, he protested and didn't go.
