Twin daughters? I don't think Tom had any twin daughters. Those were Sonny's kids. Anyway, I think GF4 should be more about the years between 1927-1941. I'm not all for the modern years. I wanna see how the Corleone empire grew, and how they became the most powerful Family. They're gonna have to get a great actor to play Vito. Robert De Niro is too old to play that character. He's like 60 or 61. Even if they try to make him look younger, I don't think it would work. Let's see if they'll bother to make another GF.
