Jonathan Taylor Thomas
Thomas was one of those actors who became famous for one single role, and then decided to end his acting career. His role in television series “Home Improvement” was a huge success, but Thomas decided to drop Hollywood for formal education. He currently has degrees from both Columbia and Harvard.
