I'm sorry to spring this disturbing trailer on readers as you wind down for the weekend (a long weekend in Australia), but this film looks too astonishing not to share. Here's part of the synopsis:

When Sukarno was overthrown by Suharto following the tragic 30 September Movement in 1965, Anwar and his friends were promoted from small-time gangsters who sold movie theatre tickets on the black market to death squad leaders...Today, Anwar is revered as a founding father of a right-wing paramilitary organization that grew out of the death squads...The Act of Killing is a nightmarish vision of a frighteningly banal culture of impunity in which killers can joke about crimes against humanity on television chat shows, and celebrate moral disaster with the ease and grace of a soft shoe dance number...

...Anwar and his friends were devoted fans of James Dean, John Wayne, and Victor Mature. They explicitly fashioned themselves and their methods of murder after their Hollywood idols...In The Act of Killing, Anwar and his friends agree to tell the filmmakers the story of the killings. But their idea of being in a movie is not to provide testimony for a documentary: they want to star in the kind of films they most love from their days scalping tickets at the cinemas.

The Act of Killing received critical acclaim at last year's Toronto Film Festival. The official website is here, though with no reference to an Australian release.
