Director Errol Morris - winner of the Academy Award, Best Documentary Feature for THE FOG OF WAR (2003) - offers a mesmerizing portrait of Donald Rumsfeld, the larger-than-life figure who served as United States Secretary of Defense and as the principal architect of the Iraq War. Love him or hate him, you cannot take your eyes off Rumsfeld in this unique kind of cat-and-mouse game of argument and counterargument, evasion and evidence. Morris takes US where few have ever been - beyond the web of words into the unfamiliar terrain of Rumsfeld's mind. THE UNKNOWN KNOWN presents history from the inside out. It shows how the ideas, the fears, and the certainties of one man, written out on paper, transformed America, changed the course of history - and led to war.
