Hiring His Sister
Francis Ford Coppola wasn't very keen on having his sister play the role of Connie. Funny enough, he thought that she was too pretty for the role. Mario Puzo requested her for the part and she actually scored the audition without Coppola's influence.
The Weirdest Occurance
The Godfather initially premiered on Saturday, November 16, and Monday, November 18th in 1974 on NBC. There were no commercial breaks. Apparently, the audiences were so sucked into the film that they didn't use the restroom. New York City Municipal Water Authorities said that they dealt with tons of overflow problems because of how many people used the bathroom at the same time after the movie was over! Both nights!
