Director Joshua Oppenheimer and executive producers Errol Morris and Werner Herzog explore Indonesian death squads in two trailers for The Act of Killing. This documentary takes a look at these brutal killers, who are celebrated as heroes, while they reenact their killings in the style of American movies. Take a look at the latest footage from this powerful film, in theaters July 19.

In this chilling and inventive documentary, executive produced by Errol Morris (The Fog of War) and Werner Herzog (Grizzly Man), the filmmakers examine a country where death squad leaders are celebrated as heroes, challenging them to reenact their real-life mass killings in the style of the American movies they love. The hallucinatory result is a cinematic fever dream, an unsettling journey deep into the imaginations of mass murderers and the shockingly banal regime of corruption and impunity they inhabit. Shaking audiences at the 2012 Toronto and Telluride Film Festivals, TThe Act of Killing is an unprecedented film and, according to the Los Angeles Times, "could well change how you view the documentary form."
