Many of u are bringing up other movies in which these two have starred in....And this is all well and good but if the original question is who was better in GF II I have to go with pacino. I might be a little biuased because in my opinion he is the greatest actor that ever lived....but i just tought his performance was so mmuch more deep than deniro....I don't think that Deniro showed enough of the emotianl range that Vito possesed.
