A new trailer for the masterful, chilling documentary The Look of Silence has been released online. The film is director Joshua Oppenheimer’s companion piece to his incredible doc The Act of Killing, and was assembled out of footage that Oppenheimer gathered during the six years he spent doing interviews throughout Indonesia about the country’s mass killings of 1965-66. While The Act of Killing provided an absolutely disturbing and crucial portrait of the perpetrators of those crimes, The Look of Silence follows the families of some of the victims as they confront the men who carried out the murders.

I caught the movie at the 2014 Toronto International Film Festival and it is essential viewing. It’s very much a companion piece to The Act of Killing, providing an even fuller picture of what it’s like to live alongside the people who carried out such atrocities—and were rewarded for it! The Look of Silence is deeply upsetting, haunting, and is undoubtedly one of the best films you’ll see all year.

Here’s the official synopsis for The Look of Silence:

The Look of Silence is Joshua Oppenheimer's powerful companion piece to the Oscar®-nominated The Act of Killing. Through Oppenheimer's footage of perpetrators of the 1965 Indonesian genocide, a family of survivors discovers how their son was murdered, as well as the identities of the killers. The documentary focuses on the youngest son, an optometrist named Adi, who decides to break the suffocating spell of submission and terror by doing something unimaginable in a society where the murderers remain in power: he confronts the men who killed his brother and, while testing their eyesight, asks them to accept responsibility for their actions. This unprecedented film initiates and bears witness to the collapse of fifty years of silence.
