Just thought of it, but shouldn't Genco be in this scene? I mean Tessio was there, while Genco was closer to the Don then Tessio. Tom states that he and Vito discussed Micheal's future many times, but at that time Tom was far from being consigliere to Vito.

Or was Genco already ill at the year 1941? Can't remember what the novel tells about this, only that he was dying from cancer, and suffered for a long time.

Ontopic: I prefer the original ending, you could feel Brando's presence even when he wasn't there. And the ending of the scene, Micheal sitting at the tabel all alone, is very powerfull I think.
