As beautiful as Angelina is, she was all wrong for the part...
Young Angelina Jolie is most unconvincing as a high fashion model. At that age, she had a round, soft face, no visible cheekbones. Added to that, her full lips make her look coarse, the opposite of elegant and aristocratic, as Gia Carangi was. Plus she lacked the typical model body type of tall, small-boned and naturally thin.
She's be better able to pull it off now, at 40, because of her low body weight and the way age takes the roundness out of women's faces.
You may agree or disagree...just my opinion.
