Famous director Ang Lee is adapting the novel Ben Fountain about the Iraq war. The story centers on 19-year-old private Billy Lynn and his company, who survive a harrowing battle that’s captured by news cameras. They are brought home by the U.S. administration for a promotional tour, culminating at the halftime show of a Thanksgiving Day football game — while facing an imminent return to the war. Kristen Stewart, Steve Martin , Garrett Hedlund and newcomer Joe Alwyn have been cast.
