Narcissism is a bitch. But it's one thing when it's all over social media and celebrity culture, and another matter entirely when it infests the broken souls of the terminally evil. Joshua Oppenheimer's documentary The Act of Killing explores this phenomenon in the context of Indonesia's barbarous purges of suspected Communists during the mid-1960s, when an estimated 500,000 to 1 million people were slaughtered. Oppenheimer and his co-director Anonymous (so named to keep him/her safe from retribution) challenged the former leaders of the Indonesian government's death squads to re-enact their crimes in any cinematic genre they chose. What results is a loud 'n' proud display of unvarnished cruelty, fed by a reptilian crawl through the depths of obscene narcissism. Unrepentant murderers ham it up for the camera; there is no mitigating self-consciousness, let alone shame or guilt. Experience the freakshow for yourself tonight at 7:30 p.m. in Webster University's Moore Auditorium (470 East Lockwood Avenue; 314-968-7487 or www.webster.edu/film-series). Tickets are $4 to $6.
