Bob Duvall is a great actor because each time out, he creates a whole, complete character. You have the feeling that you’re not seeing an actor at all, but a fully realized human being. Think of how he was in The Godfather. If you didn’t know Bobby, you’d think that he really was Tom, the consigliere. Then you see him in Santini, and he’s completely different. He’s not only a personality, he’s a consummate actor.
