Gallery: 30 pics of the women who MAY star in the Alien prequel

We don't know much about Ridley Scott's Alien prequel, but one thing we do know is that when it finally hits the screen—with a script by Damon Lindelof—a new kick-ass actress will be needed to take the place of Sigourney Weaver's Ripley. But which of these three should it be?
According to Deadline, the finalists for the lead are Carey Mulligan (Wall Street 2), Abbie Cornish (A Good Year) and Noomi Rapace (The Girl With the Dragon Tattoo).
Since all three are relative newcomers (though we've loved Mulligan ever since she starred in the Doctor Who episode "Blink"), we put together a gallery to help those of you out there who are thinking, "Who the heck are these women?" PHOTOS
