Justin Chon (The Twilight Saga), Skylar Astin (Taking Woodstock) and Sarah Wright (The House Bunny) have signed on to star alongside the previously announced Miles Teller (Footloose) in the comedy 21 and Over written and to be directed by The Hangover writers Jon Lucas and Scott Moore, it was announced today by Relativity Media's President of Worldwide Production Tucker Tooley. Production is slated to begin August 2011 in Washington with a release in 2012.

21 and Over is produced by Mandeville Films' David Hoberman (The Fighter) and Todd Lieberman (The Fighter), in association with Sir Richard Branson's Virgin Produced. Relativity Media will release the hilarious comedy in which two childhood friends drag their straight-arrow buddy out to celebrate his twenty-first birthday the night before an all-important medical school interview. But when one beer leads to another, the evening spirals into a wild epic misadventure of debauchery and mayhem that none of them will ever forget.

Looking ahead, Relativity will release David R. Ellis' Shark Night 3D on September 2, 2011, followed by Marc Forster's Machine Gun Preacher on September 23, 2011, then the highly-anticipated Immortals on November 11, 2011, starring Henry Cavill, Stephen Dorff, Isabel Lucas, Freida Pinto, Luke Evans and Kellan Lutz with John Hurt and Mickey Rourke. The studio is in production on its Untitled Snow White Project (in theatres March 16, 2012), starring Lily Collins as Snow White, Oscar-winner Julia Roberts as the evil Queen, Armie Hammer as Prince Andrew Alcott, and Nathan Lane as the hapless and bungling servant to the Queen. Relativity's expansive 2012 slate also includes its Haywire (in theatres January 20, 2012), Act of Valor (in theatres February 17, 2012), The Raven (in theatres March 9, 2012), Movie 43 (in theatres April 13, 2012), House at the End of the Street (in theatres April 20, 2012), Safe Haven (in theatres June 1, 2012) and Hunter Killer (in theatres December 21, 2012).
