I am in agreement with GP on Andy Garcia in the role of Vincent. Whether or not the character was necessary in the film or not, I wonder what your opinion is of AG playing the part. I don't feel he fit in the Corleone family at all and was totally miscast. What's your view?
By the way, shouldn't this go in the GF Trilogy section??
