John Travolta
John Travolta is one of the most famous actors on this list. Born into a Roman Catholic family, his career skyrocketed in the 70s and 80s. In 1975, Travolta converted to Scientology. This happened after his involvement on the set The Devil’s Rain. To this day, he’s vocal about his support and involvement with the Church. When speaking in an interview about Scientology, the celebrity said, “This is what I’ve discovered. When you’re unabashed about what you do, you don’t get attacked. I felt like it saved my life. Why would I want to hide that? You know, why would I inhibit what made me feel better about living? And why would I want to inhibit the tools that that subject matter gave me to live a better life?” It sounds like a decent way to live your life, not caring what other people think and firmly standing by what you believe in (Cheat Sheet).
