Anyone seen 'The Act of Killing'?
It was the Guardian critics film of the year last year, about the Indonesian death squads of the 1960s who tortured and killed communists. The documentary maker, Joshua Oppenheimer, interviews these ageing gangsters who the Indonesian government used as paramilitary death squads, and not only gets them to tell their stories but gets them to recreate scenes from their lives in a kind of 'film within a film' using prosthetics, make up and location filming.
The casual manner in which these men openly talk about the murders they committed is truly shocking. Also interviewed are government ministers who were clearly complicit in the death squads, who laugh and joke with the gangsters.
It's a genuinely disturbing film dealing with truly evil people who are, mostly, completely unrepentant about the crimes they've committed.
Not very comfortable viewing but well worth watching.
