13. Jack Gleeson
Ramsay Bolton’s death might have been the most satisfying death on Game of Thrones, but Joffrey Baratheon-Lannister’s death comes as a pretty close second. Joffrey was finally killed off in Season 4, Episode 2, “The Lion and the Rose”, so Margaery didn’t have to marry him.
Jack Gleeson was happy to leave the show. He enjoyed his role, but he didn’t want to be typecast as insane, sadistic characters forever. He starred in a play called Bears in Space in 2016, but hasn’t done much in the way of film since.
