WATCH: How the CIA Helped Make “Zero Dark Thirty”

When Zero Dark Thirty premiered in 2012, the Hollywood film about the hunt for Osama bin Laden became a blockbuster hit.

Behind the scenes, the CIA secretly worked with the filmmakers, and the movie portrayed the agency’s controversial “enhanced interrogation techniques” — widely described as torture — as a key to uncovering information that led to the finding and killing of bin Laden.

But in Secrets, Politics and Torture, premiering this Tuesday, May 19 on PBS, FRONTLINE reveals the many challenges to that narrative, and the inside story of how it came to be.

The documentary unspools the dueling versions of history laid out by the CIA, which maintains that its now officially-shuttered program was effective in combating terrorism, and the massive Senate torture report released in December 2014, which found that the program was brutal, mismanaged and — most importantly — didn’t work.

And that’s just the beginning.

Drawing on recently declassified documents and interviews with prominent political leaders and CIA insiders, Tuesday’s film goes on to examine how the secret interrogation program began, what it accomplished and the bitter fight in Washington over the public outing of its existence.

“We’ve found that, faced with 9/11 and the fear of a second attack, everybody from the head of the CIA, to the Justice Department, to the president asked ‘Can we do it?’ — meaning, can we do it legally — not, ‘Should we do it?’ says veteran FRONTLINE filmmaker Michael Kirk.

Secrets, Politics and Torture is the latest in Kirk’s acclaimed line of documentaries examining counterterrorism programs and government secrecy in the wake of 9/11: He traveled to the infamous Abu Ghraib prison in Iraq to make The Torture Question in 2005, and he just won a Peabody Award for United States of Secrets, FRONTLINE’s 2014 examination of the National Security Agency’s mass surveillance program.

“As the debate over how far the U.S. should be willing to go in the fight against terrorism continues, we felt it was important to tell the story of this CIA program, comprehensively, in documentary form,” Kirk says. “What we’ve found raises some very tough questions.”
