Jack Gleeson

After playing the loathsome Joffrey Baratheon on Game of Thrones, Jack Gleeson decided that he was ready to say goodbye to Hollywood. "I just stopped enjoying it as much as I used to," he told Entertainment Weekly back in 2014. ". . . When you make a living from something, it changes your relationship with it. It's not like I hate it, it's just not what I want to do." Following Joffrey's death in season four, Gleeson graduated from Trinity College Dublin in 2015, where he majored in philosophy and theology. He also became part of the Dublin-based theater company, Collapsing Horse.
