'House of the Dragon': Release Date, Cast, Trailer and Plot

Game of Thrones may have ended the fantasy franchise on a sour note, but a new prequel series could change all that.

House of the Dragon is HBO's first spin-off from the flagship show, which will expand on the history of Westeros first created by George R. R. Martin in his hit fantasy book series.

House of the Dragon is going to be released on HBO, like its predecessor, and it will also be available to stream on HBO Max.

The show will premiere on HBO on Sunday, August 21, and HBO Max subscribers won't have to wait as it will also be put on the streaming platform on the same day.

House of the Dragon will consist of 10 episodes in total, and these will be coming out on a weekly basis.

House of the Dragon stars Matt Smith as Prince Daemon Targaryen, Paddy Considine as King Viserys Targaryen, and Emma D'Arcy as Princess Rhaenyra Targaryen.

Also appearing in the series are actors Olivia Cooke as Alicent Hightower, Rhys Ifans as Otto Hightower, Steve Toussaint as Lord Corlys Velaryon, aka "The Sea Snake," and Eve Best as Princess Rhaenys Targaryen.

Fabien Frankel will portray Ser Criston Cole and Sonoya Mizuno also takes on the role of Mysaria in the series.

House of the Dragon is based on author Martin's book "Fire & Blood" which charts the history of House Targaryen.
