Since even before the religion’s most prominent member, Tom Cruise, jumped on Oprah’s couch, Scientology has been a source of intrigue — especially because of its appeal to Hollywood. So when ex-Scientology members — and famous faces — offer to pull back the curtain, we wait hungrily to see what they’ll say, as in Lawrence Wright’s fascinating and chilling book Going Clear, and Alex Gibney’s documentary of the same name (based on Wright’s book).

Leah Remini, with her memoir Troublemaker: Surviving Hollywood and Scientology out Nov. 3, is the latest celebrity guide into that mysterious world. In an upcoming interview with ABC’s 20/20, Remini talks with the news program about what it’s like being involved in the church. “As time goes on, you start to lose touch with the real world,” Remini says. “The mindset becomes ‘us against them’…. The decision to leave is you are giving up everything you have ever known and everything you have worked for your whole life.”

She doesn’t shy away from the topic everyone really wants to know about, either: Cruise. “Being critical of Tom Cruise is being critical of Scientology itself,” she says. “You are evil.” Watch a teaser for the interview below, which ends on a titillating cliffhanger.

Remini’s interview airs Oct. 29 at 10 p.m. ET on ABC.
