In The Unknown Known, award-winning documentarian Errol Morris turns his camera on the career of Donald Rumsfeld, who served in numerous executive positions throughout his career in Washington, D.C., but most famously as Secretary of Defense in the first decade of the 21st century. During his tenure at that job, he helped orchestrate the Iraq War, and became a controversial figure for many of the things that transpired under his watch. Morris uses his typical stylized approach -- including first-hand interviews with Rumsfeld himself -- and a wealth of archival footage to delineate how his subject's public statements and private actions did not always reconcile. The Unknown Known screened at the 2013 Toronto International Film Festival.
