House of the Dragon: Outlander Star Confirms Joining GoT Prequel Cast

Earlier this month, "Game of Thrones" and George R.R. Martin fans were treated to some first-looks at the cast from co-showrunners and executive producers Miguel Sapochnik and Ryan Condal's upcoming prequel series House of the Dragon. Now it appears another familiar face is set to join the cast, with Outlander and Peacher star Graham McTavish confirming rumors of his joining the cast. Speaking with UK fashion magazine Stylist, the actor was asked about appearing in the highly-anticipated HBO series. "I'm enjoying that, yes," McTavish responded. "I'm really having a lot of fun. We've just started. It's a very big project, so we're getting to know each other. They're lovely people. It's great, but I can't tell you too much. I can't tell you really anything about the story! But it involves a lot of dragons." Previously, the Radio Times reported that McTavish was "spotted in full costume on the 'House Of The Dragon' set in Cornwall," prompting speculation as to who the actor could be portraying.

HBO's House of the Dragon stars Emma D'Arcy (Truth Seekers), Matt Smith (Doctor Who), Olivia Cooke (Ready Player One, Sound of Metal), Rhys Ifans (Notting Hill), Steve Toussaint (It's A Sin), Eve Best (Hedda Gabler), Sonoya Mizuno (Devs), Paddy Considine (The Outsider, The Third Day), and Fabien Frankel (The Serpent). Speaking of the prequel series, check out the teaser with a 2022 promo at the end (followed by an overview of the series and more):

Cooke's Alicent Hightower is the daughter of Hand of the King Otto Hightower, raised in the Red Keep and close to the king and his inner circle. Described as 'the most comely woman in the Seven Kingdoms,' Hightower has both 'courtly grace and a keen political acumen.' Previously-cast Considine plays 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.

Toussaint's Lord of House Velaryon comes from 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. Danny Sapani was previously in talks for the role. Ifans's Otto Hightower is 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. Best's 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. Mizuno's Mysaria came to Westeros with nothing and has been 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. Frankel's Ser Criston Cole is 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.

Written by a writing team headed by Condal and including Sara Lee Hess and based on George R.R. Martin's novels, the 10-episode series has Game of Thrones director Sapochnik ("The Battle of the Bastards," "The Winds of Winter") directing the pilot and additional episodes, and partnering with Condal as co-showrunners. Martin, Condal and Sapochnik executive produce alongside Hess and Vince Gerardis. In addition, Clare Kilner, Geeta V. Patel, and Greg Yaitanes round at the directing team, with Yaitanes also co-executive producing. With Martin's novel Fire & Blood covering 150 years in the history of Westeros, there is definitely not a lack of other potential characters to consider. The initial reports that casting was underway also referenced that the Dance of Dragons (the Targaryen Civil War that destroyed nearly all of Westeros) is in the series' long-term plans, with the series expected to begin a slow build towards the bloody event.
