Kristen Stewart is gearing up to work with an Oscar-winning director. The Wrap reports that the actress is in negotiations to join the ensemble of Ang Lee’s upcoming Iraq War movie Billy Lynn’s Long Halftime Walk. Based on the Ben Fountain novel of the same name, the film is an Iraq War satire that takes place in Texas and revolves around the surviving members of a squad of soldiers who, while preparing to return to Iraq, embark on a media-intensive “Victory Tour” at Texas Stadium. Most of the story takes place on the day of their appearance at the stadium, with flashbacks scattered throughout.

Newcomer Joe Alwyn is set in the lead, but the project will reunite Stewart with her On the Road co-star Garrett Hedlund. She’ll be playing the titular character’s older sister. Lee is working from a screenplay by Oscar-winning scribe Simon Beaufoy (Slumdog Millionaire), and he intends to shoot the film in HFR 3D with the Sony F65 camera, aiming to “create a different cinematic syntax” in service of the story.

Following Twilight, Stewart has made a point to tackle interesting challenges rather than stay on the safe franchise path. Save for 2012’s Snow White and the Huntsman, she’s essentially eschewed all Hollywood fare in favor of a varied body of work, typified by last year’s Still Alice, Clouds of Sils Maria, and Camp X-Ray.

The actress will be seen later this year opposite Nicholas Hoult in Like Crazy director Drake Doremus’ sci-fi romance Equals, as well as the Max Landis-scripted action comedy American Ultra with Jesse Eisenberg. Billy Lynn's Long Halftime Walk starts filming this month, and she will also star in Woody Allen’s next film, which starts production this summer.
