Celebrities Who Got Involved with Scientology

Kirstie Alley became a devoted Scientologist in 1979 after struggling with substance abuse. Already beginning her career in Hollywood, she found the church at a vulnerable time. As her acting career soared with Cheers and film roles in the 1980s and 1990s, she credited Scientology with helping her turn her life around.

Alley remained one of the most vocal celebrity advocates of Scientology until her death in 2022. She consistently praised the church and publicly defended it against criticism. Her loyalty and outspoken nature made her one of its most prominent defenders in Hollywood, keeping her tightly associated with the movement.
