Author Lawrence Wright's explosive 2013 exposé into the operations of the Church of Scientology served as the basis for documentarian Alex Gibney's provocative effort, which looks at the testimonials of former Scientologists about what brought them to the belief system and what made them leave; the movement's founding by L. Ron Hubbard; and allegations of misconduct and abuse by the church's present leadership. 119 min. Widescreen; Soundtrack: English Dolby Digital 5.1; Subtitles: English (SDH).
