HBO has released the official trailer for the ‘Game of Thrones’ prequel series, House of the Dragon.

The new series chronicles a civil war that ripped apart Westeros 150 years before the events in Game of Thrones.  House of the Dragon comes from co-creators and showrunners Ryan Condal (Colony) and Miguel Sapochnik (Finch) and is based on George R.R. Martin’s book Fire & Blood.

The show stars Paddy Considine (Peaky Blinders) as King Viserys Targaryen, Olivia Cooke (Ready Player One) as Alicent Hightower, Emma D’Arcy (Wanderlust) as Princess Rhaenyra Targaryen and Matt Smith (Doctor Who) as Prince Daemon Targaryen.
