The Game of Thrones prequel House of the Dragon is revealing more of its sprawling cast.
The HBO fantasy drama has announced seven more castmembers, including confirming the previously rumored casting of Scottish actor Graham McTavish, a veteran of Outlander and the Hobbit trilogy.
Also among the newly confirmed cast is British actor Jefferson Hall, who is playing two characters in the show: Lannister twins (presumably identical). This casting is all the more fun/confusing as Hall also had a minor role in Game of Thrones, playing Hugh of the Vale in two episodes (Hugh was a newly made knight who was quickly killed by Ser Gregor Clegane in season one).

Emma D’Arcy as Princess Rhaenyra Targaryen, the king’s first-born child, she is of pure Valyrian blood, and she is a dragonrider. Many would say that Rhaenyra was born with everything — but she was not born a man.
Matt Smith as Prince Daemon Targaryen, younger brother to King Viserys and heir to the throne. A peerless warrior and a dragonrider, Daemon possesses the true blood of the dragon. But it is said that whenever a Targaryen is born, the gods toss a coin in the air.
Steve Toussaint as Lord Corlys Velaryon, “The Sea Snake” — Lord of House Velaryon, a Valyrian bloodline as old as House Targaryen. As “The Sea Snake,” the most famed nautical adventurer in the history of Westeros, Lord Corlys built his house into a powerful seat that is even richer than the Lannisters and that claims the largest navy in the world.
Rhys Ifans as Otto Hightower — The Hand of the King, Ser Otto loyally and faithfully serves both his king and his realm. As the Hand sees it, the greatest threat to the realm is the king’s brother, Daemon, and his position as heir to the throne.
Eve Best as Princess Rhaenys Velaryon — A dragonrider and wife to Lord Corlys Velaryon, “The Queen Who Never Was” was passed over as heir to the throne at the Great Council because the realm favored her cousin, Viserys, simply for being male.
Sonoya Mizuno as Mysaria — Mysaria came to Westeros with nothing, sold more times than she can recall. She could have wilted but instead she rose to become the most trusted — and most unlikely — ally of Prince Daemon Targaryen, the heir to the throne.
Fabien Frankel as Ser Criston Cole, of Dornish descent, the common-born son of the steward to the Lord of Blackhaven. Cole has no claim to land or titles; all he has to his name is his honor and his preternatural skill with a sword.
