Al Pacino, who played Sonny’s brother Michael Corleone in The Godfather trilogy shared: “Jimmy was my fictional brother and my lifelong friend. It’s hard to believe that he won’t be in the world anymore because he was so alive and daring. A great actor, a brilliant director and my dear friend. I’m gonna miss him.”

Robert De Niro, who portrayed a younger version of Marlon Brando’s Vito Corleone in The Godfather Part II, which Caan cameoed in for a flashback, added: “I’m very very sad to hear about Jimmy’s passing.”
