#8: Jack Gleeson

Jack Gleeson was on one of the most popular TV shows in America. Unfortunately, he played one of the most hated murderous, psychopathic characters of all time, King Joffrey Baratheon, a little too well. Some fans had a hard time understanding the sadistic character wasn’t actually him; he was just acting. After four years and four seasons, his widely despised character died. 

The 30-year-old actor told Entertainment Weekly that while he enjoyed acting over the summers with his friends as a young boy, he admitted to not enjoying acting as much as he used to. He decided to go back to school and study philosophy and theology at Trinity College. However, Gleeson has recently begun acting again in shows and movies.
