Flashbacks (at least 30%-40% of the movie): Everything between 1927, and 1941. Showing Vito, Santino, Genco, Tessio, Pentangeli, Clemenza. And Tom.

Actual Story (between Michael's death and a few years later): Vincenzo, ...

Or maybe: 1960 - 1978, or maybe: 1981 - Michael's death.

So much to show... GF V???
