He's fat as a cat, not as a human, I agree, but being a mean fat cat creates a personnality that just doesn't fit Banderas at all, to me. Greebo is a "butch" cat, as cats go, and the greasy seductive side of Banderas seems wrong... Jackman is just a natural cat, to me, he even makes Wolverine cat-like, which is saying something... But maybe I should read that part of the book again, I may have completely forgotten some vital details...
