hi, my idea of GF IV should parallel part II but instead make it a Triple storyline. dealing with Vito's early rise to power in the late 20's and 30's. (for both younger and older versions of Vito bring back both De Niro and Brando)and Michael's storyline along with Tom on what was he doing after GF II during the 60's and early 70's (its the only way to bring back Robert Duvall and we get to find out how he died)and Vincent's storyline in the 80' thru the 90's with sporadic appearences by Michael counseling Vincent before he relocates to Sicily. moreover, it deals with the rise to power. reconnecting the roots between Nephew and Grandfather. what do you people think about this idea
