Former Scientologist actress Leah Remini sent out a heartfelt thanks to HBO filmmakers for their work in making the investigative documentary Going Clear: Scientology and the Prison of Belief.

Remini made headlines after her high-profile exit from the Church of Scientology in July 2013. According to a statement released during her departure, the main reason she left the religious sect was due to issues with its management.

Remini tweeted her gratitude towards HBO’s documentary, saying, “Thank you to the brave who did something about it. And to those who didn’t have a voice, you do now.” The tweet was posted on her account on Monday.

Thank you to the brave who did something about it. And to those who didn’t have a voice, you do now. #GoingClear

In a candid interview with BuzzFeed, the Exes actress said she didn’t want her daughter to grow up under the teachings and influence of her former church. She didn’t want her child to be forced to live in a secluded Scientology compound in Florida.

“They say they’re loving, caring, non-judgmental people, but secretly, they were judging the world for not believing what they believed,” she said.

“We were working from morning until night with barely any schooling,” Remini recounted. “There was no saying no. There was no being tired.”

Going Clear debuted three months ago at the Sundance Film Festival. The documentary shed light on some of the alleged scare tactics of the religious group, and followed the Hollywood director and former Scientologist Paul Haggis as he recounted the times when he was allegedly threatened and blackmailed by the church.

A representative from the Church of Scientology issued a statement to People shortly after the revealing interview, in which Remini was named “self-absorbed” and a woman with “an insatiable craving for attention” who was exploiting “her former faith.”

“I don’t want to be known as this bitter ex-Scientologist. I’m not trying to bash anybody, and I’m not trying to be controversial. I just want people to know the truth,” Remini said in reply.
