Living in life where secrecy stealth, and courage are never in short supply, we are now getting our first glimpse into the world of the undisputed most lethal sniper in U.S. military history: the story of Navy SEAL Chris Kyle in American Sniper. Based on Kyle's best-selling autobiography and directed by a man who knows a few things about slinging guns himself, Clint Eastwood, the film follows Kyle's story from his time attempting to break into the rodeo in his youth through to earning the title of SEAL Chief and nickname as the "Devil of Ramadi" by the Iraqi insurgents. Bradley Cooper plays Kyle in a script written by Jason Hall based on the memoir that spent 13 weeks at the No. 1 spot on the New York Times best-seller list. Sienna Miller, Jake McDorman, Luke Grimes, Navid Negahban and Keir O’Donnell co-star in the film produced by Warner Bros. Launching Christmas Day 2014.
