Director Penny Lane’s provocative Sundance-sensation Hail Satan? opens this year’s 2019 Boston Underground Film Festival with its inspirational and entertaining chronicle of the extraordinary rise of one of America’s most colorful and controversial religious movements, The Satanic Temple (TST). A damning commentary on the role of organized religion in our purportedly secular society, Hail Satan? challenges preconceived notions about the objectives of the nontheistic, Salem-based, political activist movement and offers “a timely look at a group of often misunderstood outsiders whose unwavering commitment to social and political justice has empowered thousands of people around the world.” Filmmaker Lane and TST co-founder & spokesperson Lucien Greaves will be present for a post-screening Q&A.
