New Cast Members Confirmed

HBO has confirmed a number of previously-unannounced cast members, confirming at least one casting that was already figured out by fans (the popular Graham McTavish of Outlander, The Hobbit, and Men in Kilts) and a number of other significant characters who play pivotal roles in the events covered by House of the Dragon, which is based on George R.R. Martin’s Fire and Blood.

Top L-R: Ryan Corr, Jefferson Hall, David Horovitch, Graham McTavish. Bottom L-R: Matthew Needham, Bill Paterson and Gavin Spokes

Thew new, confirmed cast members are:

Ryan Corr as Ser Harwin ‘Breakbones’ Strong– Harwin is said to be the strongest man in the Seven Kingdoms. Ser Harwin is the eldest son to Master of Laws Lyonel Strong and heir to Harrenhal. [Note from Westeros: While the description fits the character from Fire and Blood, Corr doesn’t presently look like his version of the character will be presented as the “strongest man in the Seven Kingdoms.”]

Jefferson Hall as Lord Jason Lannister – The Lord of Casterly Rock and twin to Ser Tyland Lannister.

Jefferson Hall  as Tyland Lannister- A crafty and calculating politician, twin to Lord Jason Lannister. [Note from Westeros: This is a particularly amusing casting because Hall is a veteran of Game of Thrones, having been cast in the short-lived role of Ser Hugh of the Vale.]

David Horovitch as Grand Maester Mellos – A voice of reason and trusted advisor to King Viserys.

Graham McTavish as Ser Harrold Westerling – Ser Harrold has served in the Kingsguard since the days of King Jaehaerys; he is a paragon of chivalry and honor. [Note from Westeros: McTavish is the actor who’s participation was already confirmed, and fans had figured out he was liking playing Harrold Westerling, who should be Lord Commander of the Kingsguard at this time.]

Matthew Needham as Larys Strong – Younger son of Master of Laws Lyonel Strong, brought to court by his father.

Bill Paterson as Lord Lyman Beesbury – Lord of Honeyholt and Master of Coin on King Viserys’s small council.

Gavin Spokes as Lord Lyonel Strong – Master of Laws to King Viserys and Lord of Harrenhal.

The press release also confirms two castings that fans had already figured out: Miley Alcock as young Rhaenyra and
