The teaser trailer for D.J. Caruso's'I Am Number Four' has arrived, and while parts of it look like 'Twilight' for boys meets 'Smallville' -- fans of teen alien chase adventures may find some merit here. The CGI heavy flick is based on a book by James Frey and Jobie Hughes (the first of a planned six book young adult series) of the same name and is being produced by none other than Michael Bay and Steven Spielberg. The film marks the first DreamWorks feature to be released by Disney's Touchstone label after the two companies organized a five year, 30 pic deal.

'I Am Number Four' follows a group of aliens who escape to Earth after their home world is annihilated by a rival species. Once here, they disguise themselves as regular high school students and presumably do their best to fit in. Alex Pettyfer stars as Number Four, with Timothy Olyphant acting as his guardian and mentor. 'Glee's' Dianna Agron falls for Number Four's alien charms and Kevin Durand is the Commander hunting the crew down.

With all this big name muscle behind the production, one has to wonder why the trailer seems so been-there-done-that. Check it out below and then sound off with your take in the comments section.
