I saw Gia for the first time last week. It's funny, although I know so much about Angelina Jolie I have actually had little interest in most of her movies. I did enjoy Girl Interrupted, but in Gia she was painfully heartbreaking to watch. Great performances by Elizabeth Mitchell and a brief fun turn from Faye Dunaway.
I also loved Eric Michael Cole, whose relationship to Gia was beautifully never made too clear, yet it was powerfully enough depicted to make an impact. There is very little on Eric on the net but I will have to track down more of his work.
