Few filmmakers have the courage—or the tenacity—to peel back the layers of power and expose what lies beneath. Alex Gibney is one of them. In this candid interview, the Oscar-winning documentarian opens up about the making of Taxi to the Dark Side, his searing exposé on the U.S. government’s use of torture during the war in Afghanistan. With unflinching honesty and a deep sense of purpose, Gibney discusses the moral questions, the political resistance, and the emotional toll behind documenting one of the darkest chapters in recent American history.
