The American biographical war drama "American Sniper" was a major film project directed by Clint Eastwood and produced by Eastwood, Robert Lorenz, Andrew Lazar, Bradley Cooper, and Peter Morgan. It was written by Jason Hall. It is loosely based on the memoir "American Sniper" (2012) by Chris Kyle, with Scott McEwen and Jim DeFelice. The film follows the life of Kyle, who became the deadliest marksman in US military history with 255 kills from four tours in the Iraq War, 160 of the kills were officially confirmed by the US Department of Defense.

Although Kyle was celebrated for his military successes, his tours of duty took a heavy toll on his personal and family life. In the film, Cooper stars as Kyle and Sienna Miller as his wife Taya, with Luke Grimes, Jake McDorman, Cory Hardrict, Kevin Lacz, Navid Negahban, and Keir O'Donnell in supporting roles.
