Kathryn Bigelow has said her hunt-for-bin-Laden film “Zero Dark Thirty” is “all based on firsthand accounts,” but one scene’s being questioned for its accuracy. According to Dexter Filkins in the New Yorker, “The film includes wrenching scenes of a terrorist suspect being waterboarded and subjected to other forms of torture by CIA operatives; the suspect eventually surrenders information that helps lead to bin Laden . . . but the waterboarding scene, which is likely to stir up controversy, appears to have strayed from real life.” The “Talk of the Town” piece adds, “According to several official sources, including Dianne Feinstein, the head of the Senate Intelligence Committee, the identity of bin Laden’s courier, whose trail led the CIA to the hideout in Pakistan, was not discovered through waterboarding.” But Mark Boal, who also produced and wrote “The Hurt Locker” for Bigelow, defends the scene, saying, “It’s a movie, not a documentary . . . I wanted a boots-on-the-ground experience.” Bigelow, meanwhile, says she hasn’t decided on her next film. “Dark” was named best film of the year by the National Board of Review.
