Deadline reported this earlier today. Relativity Media makes it official below:

(Beverly Hills, Calif.) May 17, 2012 – Relativity Media announced today that it has acquired U.S. rights to market and distribute IM Global’s currently-titled Paranoia, directed by Robert Luketic (21) and starring Liam Hemsworth (The Hunger Games), Oscar®-nominee Gary Oldman (The Dark Knight), Oscar®-nominee Harrison Ford (Indiana Jones) and Lucas Till (X-Men: First Class). Production is targeted to begin this summer and the film will release in theatres on September 27, 2013. IM Global will handle international distribution.

In this high-stakes thriller, Adam Cassidy (Liam Hemsworth) is a charming, blue collar guy trying to get ahead in his entry-level job at Wyatt Telecom. But after one costly and illegal mistake, Adam is confronted by ruthless CEO Nicholas Wyatt. He won’t turn Adam in under one condition: Adam must agree to infiltrate the competition as a corporate spy. Adam soon finds himself packaged for success, surrounded by glamorous boardrooms, expensive cars, and a life he only dreamed of. But behind the scenes, Wyatt is pulling the strings – stopping at nothing, even murder, to win a multi-billion dollar advantage. Realizing he’s nothing more than a pawn in his boss’s ruthless game, Adam’s only way out – is to go in deeper.

The screenplay was written by Jason Dean Hall (Spread) from a previous draft by Barry Levy (Vantage Point), based on the novel Paranoia by Joseph Finder.

Paranoia will be produced by Alexandra Milchan of Emjag Productions, Scott Lambert of Film 360, a division of Management 360, and Deepak Nayar. IM Global CEO Stuart Ford, Douglas Urbanski and Gaumont’s Christophe Riandee will executive produce.

“Paranoia is a gripping story and we’re excited to add the project to our growing slate bolstered by this stellar cast. We look forward to working with our partners IM Global on bringing this film to audiences everywhere,” said Relativity’s President, Tucker Tooley.

IM Global is currently selling international rights to the film in Cannes with successful deals closing for France (Gaumont), the U.K. (Momentum), Spain (Aurum), Canada (Alliance) and Latin America (Sun).

Looking ahead, the studio will release the edge-of-your seat thriller House at the End of the Street (in theatres September 21, 2012) and the hilarious comedy 21 and Over (in theatres November 2, 2012). Relativity is currently in production on Scott Cooper’s gritty dramatic thriller currently-titled Out of the Furnace and is in pre-production on the film adaptation of Nicholas Sparks’ best-selling Safe Haven (in theatres February 8, 2013).
