Following the Indonesian military coup in the 1960s, leaders of paramilitary death squads were responsible for killing more than a million alleged Communists and others who threatened those in power. Nearly 50 years later, these crimes have gone unpunished, and the perpetrators maintain a heroic view of the atrocities they committed. This groundbreaking doc puts the cameras in the hands of some of the most notorious of these gangsters, who delight in the opportunity to glorify their past deeds by staging dramatic reenactments of their crimes on film in surreal, B-movie fashion. The result is an astonishing history lesson and a chilling view into the minds of mass murderers who only begin to feel repentant after being confronted with the filmed record of their crimes. The Audience Award winner at this year’s Berlin Film Festival, “The Act of Killing” is a testament to the power of filmmaking.
