Is Saoirse Ronan the next Bella Swan? Sorta, but not really. The "Hanna" star just landed the role of Melanie in "The Host," based on Stephenie Meyer's 2008 sci-fi novel. She'll play a Bella-type 20-year-old whose mind is slowly being taken over by an alien named Wanderer. The twist is that Melanie is fighting off the invasion with thoughts of her crush, Jared, but Wanderer starts to fall for him too. Leave it to Meyer to include a juicy love triangle.
