Some I like for their acting and good movies and some for how beautiful they look. For great movies I like Reese Witherspoone like for Legally Blonde 1 and 2. For beautiful looks and great movies I like the model Milla Jovivich. She was the star of The Fifth Element and the 4 Resident Evil movies with the 4th one coming out now.
For great looks I like Jennifer Love Hewitt, Renée Zellweger and Selma Blair. Selma Blair is Jewish and she was also in the Legally Blonde movies.
While I agree that most of the ones mentioned are smoking hot, my all time favorite is Helen Hunt. I know, I know, she was never a beauty queen, but look at her in movies like Twister. Tell me that there isn't something special about her raw beauty, no make up, hair all screwed up, even the nose that could peck bugs out of wood, but still hot as can be!
If I have to choose one then it has to be Angelina Jolie. She is the most expensive actress in the Hollywood today and every movie in which she works, is a blockbuster, the most recent example is "SALT"
Saw Aeon Flux again last night. It's a rubbish film, but well worth watching for Charlize Theron in lycra. So she is offically my favourite actress (at the moment).
