In September 2019, Deadline Hollywood reported that a second prequel from Martin and Ryan Condal that "tracks the beginning of the end for House Targaryen" was close to receiving a pilot order from HBO; the project is not considered an original sixth script, as it builds upon Cogman's idea from 2017. This prequel, titled House of the Dragon, was commissioned as a complete series on October 29, 2019. The 10-episode series is to be based on material from Fire and Blood, executive produced by Martin, Vince Gerardis, Condal, and Miguel Sapochnik; the latter two are to be its showrunners as well. In January 2020, HBO stated that the series is scheduled for a 2022 release and that the writing process has begun. Casting for the series started in July 2020. In October 2020, it was revealed that Paddy Considine was cast as King Viserys I Targaryen. In December 2020, three more castings were announced: Olivia Cooke as Alicent Hightower, Emma D'Arcy as Rhaenyra Targaryen, and Matt Smith as Daemon Targaryen. In February 2021, HBO chief content officer Casey Bloys stated that the show would start production in April, with filming occurring in England. In February 2021, Steve Toussaint, Eve Best, Rhys Ifans, and Sonoya Mizuno were confirmed to also be starring in the series. In March 2022, HBO announced a series premiere date of August 21, 2022, followed by the release of the official teaser trailer.
