I'm curious to see what they do with Omerta as a movie. I know it wouldn't be a Godfather 4....but indirectly I suppose it'd be a sequel...set in our time. The Family trying to fold into legitimate society.
I reiterate that to do a Godfather 4 would be a bad idea...since Mario isn't around anymore. Not that I wouldn't like to see a Godfather 4...just don't know if the feel would be the same.
