As the U.S. and others weigh intervention in Syria, a documentary relating to the Iraq War has scored a triple-play of berths at Venice, Telluride and Toronto. Errol Morris‘ The Unknown Known is a portrait of former Secretary of Defense, Donald Rumsfeld. Oscar-winner Morris (The Fog Of War) interviews Rumsfeld in the pic and below is a clip parsing one of the politician’s so-called “snowflake” memos. Rumsfeld says of Morris’ terming him obsessive, “I’m not. I’m cool, I’m measured.” Radius-TWC will release Stateside later this year.
