Director Kathryn Biegelow follows up the Academy Award-winning The Hurt Locker with this gritty, reportorial take on the hunt for Osama bin Laden. Rather than focus on who shot whom, the film is a sober examination of the slow, patient skill of intelligence gathering. Jessica Chastain (The Help) headlines as a dogged CIA analyst who spends more than a decade hunting down leads to find the big man himself. The climactic, stealth-filled firefight is a nerve-shredder. FULL REVIEW:Gripping drama targets the gritty details of warmaking by Devin D. O’Leary (1/10/2013). 157 minutes R.
