I saw this thread yesterday or whenever, & came back to it now because I am watching Gia on dvd for the first time. I was going to mention Mira's role in it, too, because she was so perfect as a young Angelina! Very short role, but she did it well.
It's a good movie--Angie got a Golden Globe for it. She also said in some interview that playing Gia made her so depressed she moved cross-country to NYC and gave up acting for a while.
