I Am Number Four is a movie based on a young-adult novel written by James Frey (of A Million Little Pieces fame.) It is an action/thriller about a teen (played by Alex Pettyfer) who is running for his life, frequently changing identities and bouncing from town to town to elude his would-be assassins.

Official Synopsis: John (Alex Pettyfer) is an extraordinary teen, masking his true identity and passing as a typical high school student to elude a deadly enemy seeking to destroy him. Three like him have already been killed…he is Number Four.

D.J. Caruso (Disturbia, Eagle Eye) directs the film, which also stars Timothy Olyphont. It is produced by Michael Bay.

The movie I Am Number Four will not be coming out until February, but we have a new featurette from Dreamworks to share with you.

In this clip, Caruso explains how nine children were sent to earth from another planet and hidden amongst the general population. The nine have special powers, but they do not know exactly what those are.  You can see the clip after the jump.

A few months ago, we first got word that director D.J. Caruso, who brought us such sci-fi thrillers as Eagle Eye and Distrubia was working on a brand new film based on the Pittacus Lore (aka James Frey & Jobie Hughes) book I Am Number Four. The film’s script comes from Smallville creators Alfred Gough and Miles Millar, and brings together an interesting cast of up and coming actors.

Now, we’re getting the first taste of the film’s look and feel as the very first teaser trailer has hit the web. It definitely looks like something a bit different for Caruso, giving a bit of an Island meets Twilight vibe. Here’s the official synopsis, for those who want it spelled out.

Nine infant aliens, who closely resemble humans, flee their home planet, Lorien, to hide on Earth. An invading species, the Mogadorians, have destroyed their planet, and follow them to Earth to hunt them down. Each of the nine aliens is given a guardian and will develop superhuman powers as they become adults. They are each assigned a number. These last children of Lorien can only be killed in the sequence of their numbers.

Number Four, also named John Smith, moves to Paradise, Ohio, disguised as an American high school student. He makes a friend, Sarah, a sweet Midwestern girl who is a photographer. After being on the run his whole life, Number Four falls in love and now has something to stand up and fight for.

The film joins Beastly star Alex Pettyfer, Glee’s Dianna Agron, Timothy Olyphant, and Legion’s Kevin Durand. Check out the full trailer after the jump, and catch I Am Number 4 in theaters on February 18th, 2011.
