The eagerly awaited House of the Dragon Season 3 is being filmed in the UK now, with a release date set for 2026. The popular HBO show—developed by George R. R. Martin and Ryan Condal—is a prequel to Game of Thrones and follows the bloody history of House Targaryen. Adapted from Martin’s novel Fire & Blood, the season will go deeper into the Targaryen civil war, with fresh alliances, backstabbings, and fiery clashes.
Seven New Characters Enter the Realm
According to a report by Just Jared, seven new characters have been announced for Season 3. They are:
James Norton as Ormund Hightower
Tommy Flanagan as Ser Roderick Dustin
Dan Fogler as Ser Torrhen Manderly
Tom Cullen as Ser Luthor Largent
Barry Sloane as Ser Adrian Redfort
Joplin Sibtain as Ser “Bold” Jon Roxton
Annie Shapero in an unknown role
These new additions introduce new tension into already fractured Westeros.
Familiar Faces and Notable Absences
Fan favorites Emma D’Arcy (Rhaenyra Targaryen), Matt Smith (Daemon Targaryen), and Olivia Cooke (Alicent Hightower) all return, as does Tom Glynn-Carney (Aegon II) and many, many more. Season 3 will, however, not include characters like Princess Rhaenys (Eve Best) and Lord Cregan Stark (Tom Taylor).
