The D.J. Caurso (Eagle Eye) sci-fi film I Am Number Four can add two more to its number. According to FilmDrunk, Kevin Durand (Lost, Legion) and Callan McAuliffe (the Australian sketch comedy series Comedy Inc.), have both joined the cast.  The flick is about nine earthbound aliens who escaped their planet just before it was annihilated by a rival species.  Hiding out on Earth, disguised as human teenagers in high school, the title character discovers that he is being hunted by the enemy that destroyed his planet.

Durand will play "The Commander", a character who leads the Mogadorians to chase John/Number 4 (Alex Pettyfer) and his fellow aliens to flee from their home planet.  McAuliffe will play "Sam", Number 4's best friend.  Pettyfer, Durand, and McAuliffe will co-star alongside Teresa Palmer (Bedtime Stories), Sharlto Copley (District 9), and Dianna Agron (Glee).  The film is being produced by Michael Bay and Steven Spielberg and it was written by Al Gough and Miles Millar (Smallville). I Am Number Four begins filming next month in Pittsburgh and is slated to hit theaters on February 18, 2011.
