"Twilight" actress Kristen Stewart is in negotiations to join Ang Lee's upcoming film "Billy Lynn's Long Halftime Walk".
The cast includes Joe Alwyn as the title character and Garrett Hedlund, reported Variety.
Based on the Ben Fountain novel, "Billy Lynn" will be co-financed by Jeff Robinov's Fosun-backed Studio 8, together with Chinese distribution company Bona Film Group.
Sony Pictures is handling worldwide distribution except for China, where Bona Film will release the film.
Most of the movie takes place during a Thanksgiving Day football game.
