But that doesn’t stop him. He recruits Marty Rathbun, ex-member and former inspector general of the Church of Scientology. Rathbun has become one of the most well-known Scientology critics and has praised former Scientology followers Paul Haggis and Leah Remini. Together Theroux and Rathbun attempt to dig deeper into the world of Scientology as outsiders, even visiting the Church’s Gold Base facility in California. Close
