Rooney Mara Cast as Girl With Dragon Tattoo

Who the heck is Rooney Mara? She's an American actress with a faraway look (as opposed to a come-hither look) who's done some episodic television (ER) and was in Youth in Revolt and Dare. (I don't remember her, either.) She's about to be in The Social Network, the one about the creation of Facebook. More to the point, she's just won the role of Lisbeth Salander in the American remake of The Girl With the Dragon Tattoo, and will be costarring with Daniel Craig. She beat out Scarlett Johansson and Natalie Portman in one of the most publicized star searches since Vivien Leigh scored Scarlett O'Hara.

Your thoughts about the casting, the book and American remakes of successful foreign films? I'm on deadline, else I would be more opinionated.
