You're right: the question has been answered before.

My favorite character is Frankie Pentangeli: Everyman as Caporegime. A fundamentally decent guy (see the deleted scene with Anthony, giving him a gift) caught in a giant plot between Michael and Roth that he doesn't understand and can't influence. At the end, does the only thing he can.
An absolutely brilliant, perfect, world-class, unforgettable performance by Michael V. Gazzo. He makes GFII.
