Release Date & Where To Watch

House of the Dragon will premiere August 21 on HBO at 9 p.m. ET and will be available to stream on HBO Max. The prequel is not an HBO Max Original, so it won’t be available at 3:00 a.m. ET on August 21. The new episodes will be available simultaneously as they air on the HBO channel. The first season will consist of 10 episodes.

HBO President of Programming Casey Bloys told Deadline in January 2020 that he believed the show would air “sometime in 2022.” This was before the COVID-19 pandemic shut down most productions around the globe for a period of time. HBO didn’t confirm the show’s official release date until March 2022.

Steve, who is known for roles in Prince of Persia: The Sands of Time and Judge Dredd, revealed he received racial abuse after his casting was announced in February 2021. “I didn’t realize it was a bigger deal until I was racially abused on social media when it was announced.

  • Eve Best is Princess Rhaenys Velaryon: Rhaenys is a dragonrider and wife to Lord Corlys.

Sonoya Mizuno

  • Sonoya Mizuno is Mysaria: Mysaria came to Westeros with nothing and has been sold more times than she can recall. She has risen to become the most trusted – and most unlikely – ally of Prince Daemon Targaryen, an heir to the Iron Throne. Sonoya is known for her collaborations with Alex Garland in Ex Machina, Annihilation, and Devs.

Outlander alum Graham McTavish has also been cast as Ser Harrold Westerling. “I’m enjoying that, yes,” Graham told Stylist when asked about House of the Dragon. “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.”

Additional cast members include Sian Brooke as Aemma Targaryen, Jefferson Hall as twins Lord Jason Lannister and Ser Tyland Lannister, David Horovitch as Grand Maester Mellos, Bethany Antonia as Lady Baela Targaryen, and Harry Collett as Prince Jacaerys Velaryon. Since House of the Dragon takes place centuries before the events of Game of Thrones, characters from the flagship series will not be making an appearance in the prequel. However, there is a Jon Snow spinoff in development.


The prequel is in very good hands. George R.R. Martin and Ryan Condal serve as co-creators. Miguel Sapochnik and Ryan are the House of the Dragon showrunners. They are also executive producers alongside George and Vince Gerardis.

Miguel notably directed 6 Game of Thrones episodes, including “Battle of the Bastards” and “The Long Night.” He was part of the executive producing team when the show won the Emmy for Best Drama Series in 2019.

George revealed in a blog post that he had seen all 10 episodes of House of the Dragon and praised the series. “I love what I’ve seen.   Ryan and Miguel and their amazing cast and crew have done some magnificent work. HotD is all I hoped it would be; dark, powerful, visceral, disturbing, stunning to look at, peopled with complex and very human characters brought to life by some truly amazing actors,” he wrote.


The first teaser for House of the Dragon was unveiled on October 5. The show takes place 200 years before Game of Thrones when the Targaryen dynasty reigned. Fire & Blood, the book on which the show is based, encompasses Targaryen history from Aegon the Conqueror to Aegon III. The show will prominently feature The Dance of the Dragons, a civil war that nearly destroyed Westeros.

The official trailer was released in July 2022. The subject of succession is at the heart of the series. While Princess Rhaenyra should be the rightful heir to the Iron Throne, her legitimacy is questioned because she is a woman. Prince Daemon Targaryen, the king’s brother, is also a major candidate. “I will not be made to choose between my brother and my daughter,” King Viserys I says.

“When I am queen, I will create a new order,” Rhaenyra vows. As the battle for the Iron Throne becomes more precarious as the years go on, people will have to choose sides. Alicent Hightower, the king’s second wife, believes that if Rhaenyra comes into power she can “cut off any challenge to her succession.” To make things even dicier, there are lots and lots of dragons.

Just days before the show’s premiere, HBO released a final “Fire Will Reign” promo. The threat of war looms over everyone in Westeros. “We are better defended… by whomever may dare to challenge us,” Viserys says. The quest for power clearly runs in the Targaryen family.
