When does House of the Dragon air in the UK? Release date of Game of Thrones spin-off, cast - and how to watch

House of the Dragon is a fantasy series set long before the events of Game of Thrones and focusing on the Targaryen dynasty

House of the Dragon is a new HBO fantasy series and prequel to Game of Thrones, set nearly 200 years earlier and with focus on House Targaryen.

The season premiere has just landed in the US and UK, kicking off a new epic tale of fantasy, intrigue, violence, and graphic seuxal encounters.

Both fantasy series are adapted from the George R.R. Martin’s novels - House of the Dragon is primarily based on his 2018 tome Fire and Blood, with some elements also taken from the latest instalment in his Song of Ice and Fire series.

House of the Dragon is the first of a whole slate of TV projects set in the Game of Thrones universe, which included a Jon Snow spin-off, to make it out the gate.

Other projects include The Sea Snake, Ten Thousand Ships, The Tales of Dunk and Egg, and animated prequel series The Golden Empire.

Following the disastrous final season of Game of Thrones, which many fans considered a huge disappointment, House of the Dragon will provide an opportunity to rehabilitate the fantasy franchise.
