Read the book, only saw part three, which I bought the soundtrack for, I saw Brando in person years ago...my favorite of his was in Guys ad Dolls.
U need to watch Godfather I and II bedt movies i have ever seen.
I think parts I and II are actually much better than the book.
I have seen Godfather I and II about 5 times each-——never saw III and from all that I hear I didn’t miss much.
You must treat yourself to the two originals.
