Joshua Oppenheimer and company, in their chilling, deeply disturbing, and formally audacious portrait of Anwar Congo and his comrades, who perpetrated the 1965-1966 genocide in Indonesia that murdered over a million people, find a truly subversive way to speak truth to power. These men have never been called to account for their crimes, and instead proudly brag about them and glorify themselves in front of a cowed populace. The filmmakers invited them to indulge their movie-mad fantasies and reenact their crimes in the style of their favorite film genres: gangster movies, horror, historical epics, psychedelically-colored musicals. What they believe will be further self-aggrandizement is instead a vessel for being confronted with the horrors of what they have done to others, as well as what they have done to themselves. Oppenheimer and his collaborators (and this includes the murderers) explode the boundaries of documentary filmmaking, making use of the elaborate fantasies of its subjects to uncover the dark truths underneath, and to begin the healing of a national trauma.
