Sylvester Stallone and John Travolta in "Godfather III"?! I think not! That's like casting Pee Wee Herman to play Hamlet!
I'd much rather Paramount didn't proceed with "Godfather III" if such a classic is to be ruined by the ego-dominated personas of Stallone and Travolta, on and off screen.
Why not look at other possibilities of say, casting Mickey Rourke, Harvey Keitel, Peter Coyote and Eric Roberts? Four of Hollywood's finest actors, who are able to breathe life and depth into a character like few others can.
Until then, let "Godfather III" stay just a movie waiting to happen.
