HBO’s House of the Dragon Sets Date, Reveals Characters

We’ve been hearing about hypothetical Game of Thrones spinoffs for a while. This summer, fans finally get to see one, as HBO’s House of the Dragon will debut Sunday, Aug 21, on HBO and HBO Max. For now, HBO is calling it a ten-episode drama, though no doubt they’ll leave room for more if demand exists. The premium network and streamer debuted a teaser poster today, as well as images and descriptions of the main characters.

Here’s a list of whom we’ll be dealing with over the course of the show. From the official press release:

Paddy Considine as King Viserys Targaryen, chosen by the lords of Westeros to succeed the Old King, Jaehaerys Targaryen, at the Great Council at Harrenhal.  A warm, kind, and decent man, Viserys only wishes to carry forward his grandfather’s legacy. But good men do not necessarily make for great kings.

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…

Olivia Cooke as Alicent Hightower, the daughter of Otto Hightower, the Hand of the King, and the most comely woman in the Seven Kingdoms. She was raised in the Red Keep, close to the king and his innermost circle; she possesses both a courtly grace and a keen political acumen.

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.

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.

Eve Best as Princess Rhaenys Targaryen, 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.

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.
