Game of Thrones ran on HBO from 2011 to 2019, becoming one of the most popular drama series in the world at the time of its airing.
While its final season proved divisive with audiences, it was subsequently announced that the show – an adaptation of George RR Martin’s hit fantasy novels – would continue to expand via a number of spin-off series.
Production on House of the Dragon begun last month.
The series has received a 10-episode order from HBO, and is based on Martin’s 2018 book Fire & Blood.
The events of the series take place three centuries before the events of Game of Thrones.
House of the Dragon is expected to air in 2022.
