Of course we all want to enjoy a "Godfather III" motion picture. We cannot give up just because Francis Coppola may not do it.
Try Robert Zemeckis and Steven Spielberg. They've got the pulse of the nation: Anthony Corleone, played by Michael J. Fox, takes his DeLorean back to Lake Tahoe, 1955, and blows his father's brains out before Uncle Fredo can be assassinated.
Then--whisking his mom (Diane Keaton) into the near future, she comes face-to-face with the new Don, Woody Allen.
