20. Kirk Cameron
Kirk Cameron was a rising star in the late 1980s after acting in the series Growing Pains, for which he was nominated for two Golden Globes. However he decided that there was something that he cherished more than fame, and that was faith. So, it is no surprise that he left the glamour of Hollywood and joined the evangelist church.
With another evangelist, Ray Comfort, he had founded his ministry, The Way of the Master, and together they also host a television program of the same name. Occasionally though, Cameron does appear on camera outside of his evangelical show, such as in 2014 when he starred in Saving Christmas.
