1. Kirk Cameron
Anyone that grew up watching Growing Pains knew who Kirk Cameron was. However, as famous and recognizable the young actor once was, he simply seemed to vanish off the face of the earth. The truth, however, is that he simply changed careers.
Cameron left acting to pursue a life as a man of the cloth. Along with evangelist Ray Comfort, Cameron created The Way of the Master ministry and television program. The multi-award-winning ex-actor still makes the occasional appearance in films such as Saving Christmas, however.
