As an aside here:
This is one of many threads that center on Willie Cicci. He's a minor character and doesn't have a lot of lines. Yet he looms large here because he's an example of FFC's perfect casting in GF and II. Joe Spinell looks perfect for the part, acts perfectly, and his few lines are perfect for his character.
There are lots of other examples of FFC's casting genius. Sollozzo is an important character, but only in the beginning of GF, and he appears in only three scenes. Yet, Al Lettieri is unforgettable in that role. Even Alex Rocco, a mediocre actor, was el perfecto in his three minutes as Moe Green. Take a bow, FFC!
