5. Diana Canova
Diana Canova was reportedly a member of Scientology before becoming a TV star. However, she suddenly became showered with attention from the organization when she became famous for her role in the 1970s sitcom, Soap. It is said that the church’s Celebrity Center was eager to capitalize on her new status as a TV star as well as her celebrity friends to expand its ranks.
Canova eventually became suspicious of the organization, especially its rather expensive auditing sessions. Although it took years to leave, Canova eventually did it after she stopped fearing the reprisal from other members of the church.
