Steven Spielberg and Bradley Cooper are joining forces to make military drama American Sniper.
The Oscar-nominated Silver Linings Playbook actor is already on board to star as Navy SEAL Chris Kyle in the big-screen adaptation of Chris' autobiography, reported Deadline.
Based on American Sniper: The Autobiography Of The Most Lethal Sniper In US Military History, the memoir tells the story of the expert marksman who was killed by a fellow discharged war veteran suffering from post-traumatic stress disorder.
Bradley bought the rights to the biography about a year ago, and the book has been adapted by Jason Hall.
Steven is set to produce with Bradley, Andrew Lazar and Peter Morgan, but it is not known if he will direct the film.
Bradley, who has left his role in Western Jane Got A Gun, is also in talks to star in Chef, directed by John Wells.
He would play a French cook, who has to get his career back on track after getting over his addictions.
