From 1965 to 1966, around a million people were killed in Indonesia. It was an anti-Communist purge mounted by the Army and supported secretly by the U.S. and Britain during the Cold War. Most of the victims were villagers who were rounded up and slaughtered. Indonesia has never accounted for the massacre. In fact, the killers remain heroes to this day. Joshua Oppenheimer spent time with those killers for his 2012 Oscar-nominated documentary The Act of Killing. Now, he’s made a companion film from the victim’s point of view.
