More actors join the cast of new Game of Thrones prequel A Knight of the Seven Kingdoms

Game of Thrones ended after eight seasons in 2019. The prequel show House of the Dragon wrapped up its second season earlier this year, with a third on the way in 2026. And next year, HBO will debut a new prequel show, set decades after the events of House of the Dragon but decades before Game of Thrones.

The show is called A Knight of the Seven Kingdoms, and it's based on author George R.R. Martin's Tales of Dunk and Egg novellas. The series will follow the adventures of a stalwart knight named Dunk (Peter Claffey) and his precocious squie Egg (Dexter Sol Ansell). It's set to be a lighter take on the Game of Thrones, and based on what Martin has seen, he's "so so happy" with it so far.

A proper trailer for A Knight of the Seven Kingdoms has already been shown off to insiders, and I'm betting the public at large will get to see it pretty soon. In the meanwhile, Redanian Intelligence brings us information about several new cast members, including...

Ellie McHale-Roe and Carla Harrison-Hodge (pictured above) play Lia the Lovely and Beony, a pair of sex workers who have a scene where they talk with a main character, probably Dunk, and compare sex work to jousting, since in both cases they “put their bodies in hazard for the pleasure of strangers.”

JB Moore will play a farrier, which is someone who trims and shoes horses hooves. The first season of A Knight of the Seven Kingdoms is based on Martin's novella The Hedge Knight, which is set at a tournament with jousting, so you're gonna need some horse people.

Mark O’Connor, who had a role in a cancelled Game of Thrones prequel called Bloodmoon, will play a musician at the tournament. Cara Harris will play an original character named Gwin, and then there are plenty of actors who are playing roles for which we don't have details yet, including Eric Nolan, Michael O'Mara and Riain Ó Conchobhaír, the latter two of whom are pictured below:
