second season Gregor Clegane Lannister Dean-Charles Chapman Tommen
Although many of the cast returned after the first season, the producers had many new characters to cast in each of the following seasons. Because of the large number of new characters, Benioff and Weiss postponed introducing several key characters in the second season and merged several characters into one, or assigned plot functions to different characters. Some recurring characters were recast over the years; for example, Gregor Clegane was played by three different actors, while Dean-Charles Chapman played both Tommen Baratheon and a minor Lannister character.
