It's been two years since HBO's Game of Thrones sputtered out its series finale and there are now a number of new series in the works. The first of those to get a full series order, House of the Dragons, is now officially in production. Based on GoT creator George R.R. Martin's book Fire & Blood, the series will "tell the story of House Targaryen (a.k.a. the House that gave us the Mother of Dragons herself, Daenerys Targaryen) and take place 300 years before the events of Game of Thrones."
The series stars Paddy Considine (Peaky Blinders, 24 Hour Party People) as "Mad" King Viserys Targaryen, Matt Smith (Dr Who, The Crown) as Prince Daemon Targaryen, Emma D’Arcy (Hanna, Truth Seekers) as Princess Rhaenyra Targaryen, and Olivia Cooke (Sound of Metal, Ready Player One) as Alicent Hightower, who is the daughter of the Hand of the King (former Super Furry Animals member Rhys Ifans). House of the Dragon is co-created by Martin and Ryan Condal (Colony, Hercules), and they will be showrunners, along with Miguel Sapochnik, who directed a some of Game of Thrones' most action-heavy episodes (including "Battle of the Bastards" and "Hardhome").
