It is not hyperbole to call The Act of Killing an epochal film. Directed by Joshua Oppenheimer, an American based in Denmark, the documentary brings viewers into the minds of mass murderers, illuminates a horrific piece of recent history that few know anything about, and could end up ushering in a new era in Indonesian politics and identity. There has probably never been a film that bears even the slightest resemblance to The Act of Killing and it is highly improbable we will ever see anything like it again.
