James McAvoy played wuss-tastic Wes Gibson before Angelina Jolie and Morgan Freeman turned him into a badass assassin in the action packed Wanted. Last year he starred opposite Keira Knightley in Best Pic nominee Atonement, a highly underrated film. We first noticed James as Mr. Tumnes in The Chronicles of Narnia: The Lion, The Witch and The Wardrobe. Hayden Christensen let us down as Anakin Skywalker in Star Wars Episodes II and III which never really boosted his career they way they were supposed to. Maybe it had something to do with his performances (of course it did!). He's made a few mediocre films since then, like Factory Girl, Awake and Jumper; and recently he got engaged to actress Rachel Bilson, from The O.C.
