The cast for DreamWorks‘ I AM NUMBER FOUR just keeps growing. The latest addition is Jake Abel (Percy Jackson & the Olympians: The Lightning Thief), who joins Timothy Olyphant, Kevin Durand, Alex Pettyfer, Dianna Agron, Callan McAuliffe and Teresa Palmer. Abel will play the earthbound rival to Alex Pettyfer’s Number Four. Jake’s character is the High School Quarterback named Mark who’s afraid Number Four is stealing his spotlight.

I Am Number Four is an adaptation of the upcoming young-adult science fiction book by James Frey and Jobie Hughes which revolves around a group of nine aliens who escaped their home planet just before it was annihilated by a rival species. Hiding out on Earth, Number Four disguises himself as a human high schooler, only to discover he’s still being hunted by his planet’s enemy.

Michael Bay is producing alongside Steven Spielberg. Al Gough and Miles Millar (Smallville) wrote the screenplay.

I Am Number Four is scheduled to begin principal photography next month in Pittsburgh and is slated to hit theaters on February 18th, 2011.
