If you ask people about the fight between Sonny Corleone and his brother-in-law Carlo Rizzi, you’ll generally get one of two reactions. People will either cringe at its brutality or point out the miscues, like when James Caan takes a big swing that lands about a foot away from Gianni Russo (Carlo)’s face. But the fight was a lot closer to reality than critics think. When Caan tossed Russo over the fence, then beat him with a trash can, he allegedly broke two of Russo’s ribs and cracked his elbow. There were rumors that Caan and Russo didn’t get along well, which may have contributed to the brutality of the brawl. But as a means of setting up Sonny’s eventual demise, Francis Ford Coppola’s scene is spot-on.
