No way should Di Caprio play a young Sonny. He's not Sicilian enough. He is a pretty boy who had a good upbringing. He is a good actor but no Sonny, the natural traits are not there. Sorvino is too old to play Clemenza,likewise for Buscemi(although the two would be fantastic). Vin Diesel as Luca? Put Keanu Reeves in there as well. The worst actors in history! What made the Godfather so great was the acting ability of the entire cast. They were all connected to the NY Sicilian scene, so they were able to live the roles. Charlize Theron as Kaye? She's too hot. Kaye was a plain Jane, Charlize is too sexual and too old. Kirsten Dunst might be a better fit. The problem with casting these roles as younger than before, is that there aren't any kids out there who could pull it off. You would have to go back a generation or two. If not, you HAVE TO find a way to bring De Niro back in to the fold, and maybe James Gandolfini and some of the cast of the Sopranos. God I hate Andy Garcia in this series.
