Yesterday we reported that Glee's Dianna Agron has signed on for director D.J. Caruso's new film and now we have news of two more cast members signing on. FilmDrunk is reporting that Kevin Durand and Callan McAuliffe have joined the cast of I Am Number Four.

The site reports that Durand will play "The Commander" who chases Alex Pettyfer and Teresa Palmer's Number Four and Number Six characters to Earth from their alien planet. McAuliffe was said to play the role of Sam, who becomes Number Four's best friend.

D.J. Caruso is directing the film from a script by Smallville creators Alfred Gough and Miles Millar. Shooting was said to begin next month in Pittsburgh.
