HBO's Game of Thrones prequel series, House of the Dragon, has added six new members to the cast, including two Lannister characters. House of the Dragon takes place 300 years prior to the events of Game of Thrones and is based on the book "Fire and Blood" by author George R.R. Martin. The series was created by Martin and Ryan J. Condal for HBO, which will be the first spinoff show of the massively popular Game of Thrones series.

House of the Dragon will chronicle the beginning of the end for House Targaryan, once the ruling house within Martin's Seven Kingdoms universe. Known for taming and using dragons to conquer their domain, House Targaryan were known for their silvery hair and purple eyes (although this was not adhered to in Game of Thrones), as well as their incestuous relationships. The show has been in production since April 2021 and is set to debut a 10-episode season sometime in 2022. Casting for House of the Dragon kicked off in 2019 with a vast array of talent joining the prequel show. Paddy Considine, Emma D'Arcy, Olivia Cooke, Rhys Ifans, Graham McTavish and Matt Smith are just a few of the names already attached to the show in key roles (although the notable role of Aegon II has yet to be announced).

Now, via TV Line, six new members have been announced for the show. The casting includes two new members of House Lannister, which was the ruling House during Game of Thrones' reign. Joining the cast are: Ryan Corr as Ser Harwin “Breakbones” Strong,  Jefferson Hall as Lord Jason Lannister and Tyland Lannister; David Horovitch as Grand Maester Mellos,  Matthew Needham as Larys Strong, Bill Paterson as Lord Lyman Beesbury, and Gavin Spokes as Lord Lyonel Strong.

House Lannister was a prominent house in Game of Thrones and featured some of the most colorful characters. Perhaps the most popular of them was Tyrion Lannister, played by Peter Dinklage, whose sister, Cersei Lannister, as played by Lena Headey, served as one of the primary antagonists of the show. Nikolaj Coster-Waldau played the brother (and lover) of Cersei, Jaime Lannister, who was a far more redemptive character, and Charles Dance played Tywin Lannister, the patriarch of the family.

Including the Lannister line in House of the Dragon will surely make for some great drama, as their rivalry with House Targaryan is one that changes the face of the Seven Kingdoms. Viewers could certainly read up on that journey in Martin's book, but if it's anything like Game of Thrones, then the shocks, surprises, and sudden deaths may be best saved for the show. Either way, there will be plenty of material to mine, and House of the Dragon will benefit from being adapted from a finished work, unlike Game of Thrones, which is still two books shy of being complete, despite the show being over.
