Editor's note: Peter Bergen and Bob Baer discuss reaction to interrogation scenes in a film that portrays the hunt for Osama bin Laden.
"Zero Dark Thirty" is a likely shoo-in, deservedly, for Oscar nominations for best director (Kathryn Bigelow) and best screenplay (Mark Boal) and perhaps a slew of other categories.
Jessica Chastain, who plays Maya, a CIA analyst who in the film is the key player in finding Osama bin Laden, is reminiscent of Cate Blanchett in both looks and talent. The movie is beautifully filmed, and the propulsive score moves the action forward effectively.
Leaving aside its obvious merits as a film, how well does Zero Dark Thirty tell the complex tale of the decade-long hunt for bin Laden after 9/11? It's a valid question to ask since, after all, Bigelow told The New Yorker's Dexter Filkins, "What we were attempting is almost a journalistic approach to film," and Boal told the Los Angeles Times, "I wanted to approach the story as a screenwriter but do the homework as a reporter."
