After debuting some sneak peek videos, DreamWorks Pictures has finally released the first full trailer for "I Am Number Four" via Yahoo! Movies. It follows an extraordinary boy who looks like just a normal guy before he learns about his special abilities.
Alex Pettyfer plays John Smith aka Number Four, one of alien teens who is sent from another planet to Earth to hide from ruthless enemies sent to destroy him. He is changing his identity, assimilating to high school on Earth, and moving from town to town with his guardian Henri.
In the small Ohio town he now calls home, John encounters unexpected, life-changing events - his first love, powerful new abilities and a connection to the others who share his incredible destiny. Now that the first three of them have been killed, Number Four must fight to survive.
Joining Pettyfer in the cast ensemble is Dianna Agron who portrays Sarah, John's love interest. Timothy Olyphant is cast as Henri, while Teresa Palmer plays another alien teen called Number Six.
Directed by D.J. Caruso, "I Am Number Four" is backed by Michael Bay and Steven Spielberg who serve as producer and executive producer respectively. This sci-fi thriller is set to be dropped in U.S. cinemas on February 18, 2011.
