The project, which was written by Jason Hall ("Paranoia"), will be a co-production between Warner Bros. and Dreamworks.
Film is based on the bestselling book “American Sniper: The Autobiography of the Most Lethal Sniper in U.S. Military History” by Chris Kyle, Scott McEwan and Jim DeFelice.
Book chronicles Kyle's journey from Texas rodeo cowboy to Navy SEAL Chief with the highest number of sniper kills in U.S. military history. Cooper's production company optioned the rights to the book a year ago. He fast tracked it after Kyle was shot and killed on Feb. 2 at a shooting range in Erath County, Texas.
The suspect is Eddie Ray Routh, a veteran suffering from post traumatic stress disorder. Kyle had reportedly taken Routh to the range to help with his PTSD.
Spielberg and Cooper will produce with Andrew Lazar and Peter Morgan. DreamWorks’ Kristie Macosko Krieger and Adam Somner will also be involved in a producing capacity.
Sheroum Kim will oversee the project on behalf of Cooper's production company, 22nd & Indiana Pictures.
Jon Berg will oversee the project for WB.
Spielberg originally intended to direct "Robopocalypse" as his follow-up to "Lincoln," but that film was pushed back in January.
Cooper recently exited the troubled "Jane Got a Gun" project.
