Saoirse Ronan (Atonement) 

With her Oscar-nominated performance as Atonement's Briony Tallis—a young girl who falsely accuses her sister's lover of a crime—13-year-old Saoirse Ronan became the fresh-face-to-watch on the film scene. Expect to see a lot of the Irish actress in the coming year—in 2008, she will star in three films, including the film version of Alice Sebold's best-selling novel The Lovely Bones.
