Welcome to the Boards, my friend!

Do I prefer Caan or De Niro for the role of Santino Corleone? Well, while De Niro is one of my favorite actors, and while his screen test was electrifying, I believe Caan was the best choice, and the right choice for the role. De Niro's portrayal of Sonny came across as psychotic, and there was concern that he would have made the character one-dimensional. IMO, De Niro is a great enough actor to realize that Sonny had a soft side, but Coppola prefered Caan as Sonny, and I agree with his choice. He pulled off the role flawlessly.
