George Lucas turned Portman into a full-fledged international star when he cast her as Padme Amidala, the woman who would become the mother of Luke and Leia, in the Star Wars prequel trilogy.
Woody Allen has fallen under the spell of Johansson, casting her in Match Point, Scoop and the upcoming Vicky Cristina Barcelona, in which she reportedly has a steamy sex scene with Penelope Cruz.
"Scarlett is just a naturally great actress, Allen has stated. She can do no wrong and is incapable of a bad moment. Shes very sexy, very pretty. She was just touched by God."
Winner: Johansson. Although Star Wars made Portman a household name, Allen is a far better director than Lucas, who seems ill at ease directing humans.
