As it clocks in at less than three minutes, I’m not entirely sure why this classes as an ‘extended’ trailer, other than that it featrues different footage to the theatrical version. However the more I see, the more intrigued I am by this teen sci-fi drama, which seems rather Twilight but far darker and more action packed at the same time. The movie is about a group of nine young people from a planet called Lorien who have been attacked by a hostile race from another world. The youngsters and their guardians evacuate to earth, where three are killed. The protagonist, a Lorien boy, Number 4 (Alexx Pettyfer), hides in Paradise, Ohio, as a human and tries to evade his predators. The film also stars Glee’s Dianna Agron, Kevin Durand and Timothy Olyphant. It hits UK cinemas on February 18th, 2011, but click below for the extended trailer.
