We recently got a first look at Michelle Williams in full Marilyn Monroe costume on the set of My Week With Marilyn. She's portraying the blond bombshell in a biopic about the '50s star, while her former Dawson's Creek costar Katie Holmes is taking on her own recognizable role. She spent the Summer dressed up as Jackie Kennedy for the History Channel miniseries The Kennedys. Both ladies have big shoes to fill with such iconic characters, and we want to know which actress you think looks the part best?
