It looks like an amazing movie! I read some where that Scarlett Johansson was also considered for the role as Marilyn. When I first heard that Michelle Williams got the part, I thought to myself, "she looks nothing like Marilyn, how will she do it?". Now that I saw the trailer I can see she totally nails it, at least the essence of Marilyn which clearly comes through. As a huge fan of Marilyn, I can't wait to see it!
