Here we have a new trailer for the upcoming sci-fi action movie I Am Number Four, based on the books by Jobie Hughes and James Fray.

The film follows the mysterious teenager John Smith (Stormbreaker’s Alex Pettyfer) who isn’t your average teen. He is an alien on Earth who is on the run from the Government. He is not alone though, and the first three of his kind have already been taken down and he has to stay one step ahead with his guardian (Timothy Olyphant). Whilst hiding out in Ohio, John begins to experience human life, finding love whilst also discovering new super and dangerous abilities.

Check out the trailer below:

It certainly looks like it has the potential to kick off another teen based franchise, but with some decent action and thrills along with the romantic sub-plot. Alex Pettyfer also looks impressive, putting on a very convincing American accent, hopefully this film will see him gain more roles as he has proved to be a very talented actor as he was easily the best thing about the Stormbreaker movie. I Am Number Four is directed by D.J. Caruso (Disturbia, Eagle Eye) and is set to hit cinemas on February 18th 2011.
