House of the Dragon

About this series

In a nutshell: feuding families, backstabbing (literally), and lots of side-eye. Taking place two centuries before HBO’s acclaimed fantasy saga Game of Thrones, House of the Dragon returns to Westeros to depict the battle to rule the powerful House Targaryen. But who will seize control of the dynasty? And to what lengths are they willing to go? With an all-star cast featuring Paddy Considine, Matt Smith, Olivia Cooke and Emma D’Arcy, House of the Dragon is based on author George R.R. Martin’s novel Fire and Blood.
