Watch Jessica Chastain Hunt Down Osama Bin Laden in New Zero Dark Thirty Trailer

In the intense new trailer for Zero Dark Thirty, Oscar nominee Jessica Chastain ditches the glamorous, flowing dresses of Broadway's The Heiress for down 'n dirty desert fatigues. Zero Dark Thirty chronicles the Navy SEAL mission that led to the killing of Osama Bin Laden, and marks the follow-up to Oscar winner Kathryn Bigelow's 2010 Best Picture winner The Hurt Locker. In what looks like an equally pulse-pounding and nerve-wracking film, Chastain does some serious contemplation as she works to carry-out the historical task in front of her. The movie hits theaters on December 19, until then you can catch Chastain in The Heiress, which opens at the Walter Kerr Theatre on November 1.
