WTOP Entertainment Reporter Jason Fraley marks the 10th anniversary of the Oscar-nominated documentary “The Act of Killing” (2012). Filmmaker Joshua Oppenheimer called in back in 2014 to reflect on his gutsy interviews with actual perpetrators of Indonesian genocide. You’ll also hear their 2016 interview about his companion piece “The Look of Silence,” which allowed optometrist Adi Rukun to grill the death-squad leaders about his brother’s murder.
