On March 30, HBO Max tweeted an update about "House of the Dragon": The first episode of the "Game of Thrones" prequel will be released on Sunday, August 21. The season will consist of ten episodes, which will air on HBO every Sunday and will afterwards be available to stream on HBO Max.
The press release confirmed a lengthy cast list, including Paddy Considine as King Viserys Targaryen, Olivia Cooke as Alicent Hightower, and Matt Smith as Prince Daemon Targaryen. There will reportedly be no Starks, Snows, or Baratheons in the series, but there will be at least two Lannisters: twins Tyland and Lord Jason.
The first season, based on George R.R. Martin's "Fire and Blood," will be set “200 years before the events of 'Game of Thrones,'” and will tell “the story of House Targaryen." The novel has received mixed reviews, with some calling it "a masterpiece" and others calling it "dramatic" and "salacious."
In October 2021, HBO Max released a teaser trailer. Apart from Smith's character rasping out, "Gods, kings, fire, and blood. Dreams didn't make us kings — dragons did,” there is no communication between characters, yet there are enough emotional and gorgeously quick visuals to get viewers excited for Season 1.
