Dianna Agron, best known for her cheerleader roles on "Glee" and "Heroes," has joined the cast of I Am Number Four to play a… cheerleader. In the DJ Caruso-directed film, Agron will dump her jock boyfriend to cozy up to alien refugee Alex Pettyfer. Also on board are Sharlto Copley as Pettyfer’s guardian and Teresa Palmer as Number Six.
The movie based on a novel co-authored by James Frey, tells the story of nine alien children who escape to Earth after being hunted by a hostile race. There they hide in Middle America where they shift nervously in their seats whenever Syfy shows reruns of "Roswell." (THR)
