Alex Gibney’s documentary Going Clear: Scientology and the Prison of Belief, based on Lawrence Wright’s 2013 book, has the potential to rock your world. Although South Park’s brilliant Trapped in the Closet already covered the same ground, Going Clear features stellar interviews with a handful of ex-Scientologists. If a 21-minute cartoon parody doesn’t convince you that Scientology is batshit crazy, see this film. Beware: by the end, you’ll question a lot more than just Scientology.
