Warner Bros. Pictures and Village Roadshow Pictures have just unveiled the teaser trailer of “American Sniper,” starring Bradley Cooper and directed by Clint Eastwood. The trailer may be viewed here after the jump.

In the film, U.S. Navy SEAL sniper Chris Kyle (Cooper) is sent to Iraq with only one mission: to protect his brothers-in-arms. His pinpoint accuracy saves countless lives on the battlefield and, as stories of his courageous exploits spread, he earns the nickname “Legend.” However, his reputation is also growing behind enemy lines, putting a price on his head and making him a prime target of insurgents.

Despite the danger, as well as the toll on his family at home, Chris serves through four harrowing tours of duty in Iraq, becoming emblematic of the SEAL creed to “leave no man behind.” But upon returning home, Chris finds that it is the war he can’t leave behind.

A two-time Oscar® nominee for his work in “Silver Linings Playbook” and “American Hustle,” Cooper heads the cast, which also includes Sienna Miller (HBO’s “The Girl”), Jake McDorman, Luke Grimes, Navid Negahban, Keir O’Donnell, Cory Hardrict, and Erik Ladin.

Oscar®-winning filmmaker Clint Eastwood (“Million Dollar Baby,” “Unforgiven”) is directing “American Sniper” from a screenplay by Jason Hall, based on the book by Chris Kyle, with Scott McEwan. The autobiography was a runaway bestseller, spending 18 weeks on the New York Times bestseller list, 13 of those at number one.

The film is being produced by Eastwood, Robert Lorenz, Andrew Lazar, Bradley Cooper and Peter Morgan. Tim Moore, Jason Hall, Sheroum Kim and Bruce Berman are serving as executive producers.

The behind-the-scenes creative team includes Oscar®-nominated director of photography Tom Stern (“Changeling”); Oscar®-nominated production designer James J. Murakami (“Changeling”) and production designer Charisse Cardenas; Oscar®-winning editor Joel Cox (“Unforgiven”) and editor Gary D. Roach; and costume designer Deborah Hopper.

Opening across the Philippines on January 21, 2015, “American Sniper” is distributed by Warner Bros. Pictures, a Warner Bros. Entertainment Company.
