Game of Thrones prequel series House of the Dragon has added seven new names to its cast, and there’s another set of Lannister twins on the scene. HBO has provided character descriptions for each of the new cast members on its official website.
Jason Lannister is the Lord of Casterly Rock and twin to Ser Tyland Lannister, a prominent lord who served the realm as master of ships for Viserys I Targaryen, as master of coin for Aegon II Targaryen, and as Hand of the King for Aegon III Targaryen. Both characters will be portrayed by Jefferson Hall, a returning Game of Thrones alum who played Hugh of the Vale in the HBO series.
Meanwhile, Ryan Corr (Wolf Creek 2, The Water Diviner) has been cast as Ser Harwin “Breakbones” Strong, who HBO describes as “the strongest man in the Seven Kingdoms.” David Horovitch (Miss Marple) will play Grand Maester Mellos, a close advisor and voice of reason to King Viserys.
