The Cast: Taylor Lautner, Lily Collins, Maria Bello, Alfred Molina, Jason Isaacs, Sigourney Weaver The Director: John Singleton (Shaft, Boyz n the Hood) The Plot: What if you discovered your whole life was a lie? Lautner plays a high school senior who catches a picture of himself on a missing-persons website. Then, after his parents are killed by assassins, he sets out to learn his true identity -- by any means necessary. The Reason to See It: The Twilight six-packer finally carries his first film, an intense action-thriller that gives the star an opportunity to kick box, slide down hills, jump out of exploding houses and more. The film also marks a coming out of sorts for Collins, the unexpectedly beautiful daughter of rocker Phil Collins.
