Anwar Congo and his friends have been dancing their way through musical numbers, twisting arms in film noir gangster scenes, and galloping across prairies as yodelling cowboys. Their foray into filmmaking is being celebrated in the media and debated on television, even though Anwar Congo and his friends are mass murderers. The Act of Killing is a journey into the memories and imaginations of the perpetrators, offering insight into the minds of mass killers. And The Act of Killing is a nightmarish vision of a frighteningly banal culture of impunity in which killers can joke about crimes against humanity on television chat shows, and celebrate moral disaster with the ease and grace of a soft shoe dance number. Director Joshua Oppenheimer joins us to talk about how the making of this remarkable documentary has changed his life.
