Sollazo was a great character in the movie. Luca was a great character in the book.

Movies have time constraints so they have to cut things out like Luca character.

. I think they had the whole family in the meeting with Sollazo because the don wanted to show a united front when he said no. It worked out badly for the Don because he did not talk it over with the kids before he met with the guy.

But then it was only a movie and not real.

If the talk was real he would have said yes because it was too much money to say no. It would not have had a big group of people their either.
