Scarlett burst into public prominence as a young teenage actress, first being noticed in the indie classic Welcome to the Dollhouse. Since then she's made over 20 films, likely being one of the few actors in history with as many films as her age, being born in 1984, so she's still only 24. Her most acclaimed and demanding part was as the friend of Bill Murray in Lost in Translation, when both were temporarily American fish out of water in Japan.
If anyone is going to be the new Marilyn, I nominate Scarlett, who has better acting skills and is just as beautiful, resembling the fabulous glamour queens of the silver screen. Currently a Woody Allen favorite, she's appeared in his films Match Point and Vicky Christina Barcelona.
Somehow, she manages to have both the "girl next door" and the classic voluptuous film siren qualities, which make her one of the most popular and alluring modern actresses.
