After taking his time to pick his next directing job, Steven Spielberg decided on Warner Bros.’ “American Sniper” starring Bradley Cooper.

With sci-fi pic “Robopocalypse” put on hold, Spielberg hadn’t chosen his next project after a long award season campaigning for “Lincoln.”

The news was broken by the Hollywood Reporter.

Jason Hall penned the script about a Navy Seal recounting his military career, which includes more than 150 confirmed kills. Film is based on the book “American Sniper: The Autobiography of the Most Lethal Sniper in U.S. Military History” by Chris Kyle, Scott McEwan and Jim DeFelice.
