Ms. Portman has already established herself as an accomplished actress, especially with the Oscar nomination this past season, and she does seem more willing to try roles that don't cast her as the beauty queen, but more as a unique person in a given situation than many other young actresses.
She's actually originally from a town not too far from me, and I've encountered a few people that knew her when she was growing up and they all said essentially what we've said about her: that she is real, honest, naturally beautiful, humble, and whip smart.
I wish her all the best, though I think she's already solidified herself and has the staying power.
Take care all.
