some random ideas
imperioli to play paulie..
deniro of course as vito, we'll find out if leo could play sonny when Gangs of NY comes out...
michael, connie, and fredo are way too young to matter much..it's a waste of time to try to cast them...
gandolfini as luca would be a great device to get the film made, but sizemore looks more like lenny montana....that's a brilliant idea
if vince vaughn wasn't 50 feet tall, he might make an interesting sonny, but he's a bit old for the part, too
how about a couple of n sync or backstreet boys a the guys that luca chops up from chicago.....just so we can see it happen...(somebody's got to play that part)
there's should be no kay, but what about sandra???
