I have heard Paramount Pictures wants to make GF4, if Coppola refuses to make it, PP will call other directors but I think it would not be the same. Anyway, I think GF4 have to be told lik a nowadays story(In 2005 or 2006, Vincent talking by cell phone, bussines with Internet, etc), of course Michael living the 80s and dying in 1997 with the last great Mafia funeral, we need to see how is Michael's life after Mary`s death and his arguments with Kay Adams who blames Michael's life style because of Mary's death. The GF4 script(written by Mario Puzo)says Vincent got into drugs bussines against Corleone Family rules and the empire falls down because of the drugs bussines and because he is not as good Don as Michael and Vito, so the Vito Corleone`s words would come true. "Drugs will destroy us in the years to come" Vincent could end up in jail.
Because there are 3 points:
1-The First Generation would build an empire.(Vito)
2-The Second one would keep it and making stronger.(Michael)
3-The Third one would take it to the misery.(Vincent)

I think GF4 must be the REAL LAST GF MOVIE.
There must be GF4 because we need to see the end of Corleone empire and Vincent in jail like the real life today.
We don`t need GF5 would not make sense. THE GF4 is the last movie.

And about Young Sonny`s part(Leonardo di Caprio) could be exacly told as it is told in the book novel.

What do you think?
LET`S ASK COPPOLA TO MAKE THE GODFATHER 4!!!
DOES ANYBODY HAVE COPPOLA`S PERSONAL EMAIL?
LET`S GET TOGETHER!!!
WE WANT GF4!!!!!
