Leah Remini 'Risking Everything' by Criticizing Tom Cruise (VIDEO)

Leah Remini isn't just taking on Scientology, she's going squarely after Tom Cruise in a new interview about her departure from the church.

Leah sat down with "20/20" and revealed her fears about taking on Scientology, saying ... "Being critical of Tom Cruise is being critical of Scientolgy itself. You are evil."

She also says it's "giving up everything you've worked for your whole life" -- if you decide to leave Scientology. Remini's been very vocal about her issues with the church since leaving in 2013. She's said she left because she didn't want to raise her daughter as a Scientologist.
