For anyone who likes Orson Welles or Rita Hayworth, you should see "The Lady From Shanghai". They are both in it (She looks unbelievable!), great movie.
I love: Anna May Wong, Audrey Hepburn (Who doesn't? This is my favorite picture of her), Bette Davis, and Marlene Dietrich (My favorite photo of her). There's many more old Hollywood Stars I love, but I don't have any more photos on my work computer.
I agree that there aren't really any modern day equivalents, but Cate Blanchett did come to mind, for me.
