The Act of Killing (2012)

The Act of Killing forces perpetrators of Indonesia's 1965 mass killings to reenact their murders in the style of their favorite movie genres—musicals, westerns, film noir—producing the most disturbing examination of evil, impunity, and cinematic complicity ever filmed. Its 122-minute running time immerses viewers in a moral vertigo unmatched by #4 Hoop Dreams, which chronicles systemic inequality; Oppenheimer's film directly implicates the audience in the killers' self-deception, a technique that makes it more uncomfortable than the average documentary.
