With such a huge cast, Game of Thrones actors rarely played multiple characters. Actor Dean-Charles Chapman, who previously played Martyn Lannister, took on the role of Tommen starting with season 4 Episode 2, "The Lion and the Rose). Chapman played the character in seasons 4, 5, and 6, receiving main cast billing starting with season 5. To emphasize the importance of the Lannisters' hair color, the entire family is portrayed with lighter hair throughout Game of Thrones. As such, Chapman's dual roles reemphasize the prominence of the "Lannister look" throughout Game of Thrones.
