I Am Number Four is an upcoming sci-fi adventure based off the popular book series, written by James Frey and Job Hughes.  Michael Bay and Steven Spielberg produced the film, which was directed by D.J. Caruso of Eagle Eye and Disturbia fame.

The first trailer for I Am Number Four is now online and it focuses primarily on the setup to the film, which involves a group of nine humanoid aliens that flee to Earth after their home world is destroyed.  These super-powered beings – who are named Number One, Number Two, etc. – are now being hunted down (sequentially) by the same beings that destroyed their planet.

Number Four (Alex Pettyfer), is the narrator of the teaser and the protagonist of the film itself.  He hides under the name John Smith (heh) and is constantly on the run with his guardian, Henri (Timothy Olyphant) – that is, until he arrives in a small Ohio town and falls in love with a young woman named Sarah (Dianna Agron of Glee fame).

The romantic angle of the plot bears a resemblance to Twilight, albeit with super-powered aliens instead of sparkling vampires.  I Am Number Four looks to have more action and less moody teenage drama than that ultra-successful franchise, which, in our opinion, is definitely a good thing.

Most of the visual FX on display in this teaser are somewhat less than impressive but so far look to not be too cheesy.  The combination of teenagers and super powers like telekinesis or the ability to shoot energy rays from their hands – well, you would be forgiven if you started watching the I Am Number Four trailer halfway through and thought it was the preview for X-Men: First Class.

Does I Am Number Four have the potential to kick-start an exciting new sci-fi franchise?  Best we wait to see if the full trailer improves on the teaser and hints at a final product that will entertain more than the tween crowd.

I Am Number Four arrives in theaters in the U.S. on February 18th, 2011.
