Although not one of the main players competing for the Iron Throne, Korlis Velarion does stake in the game. His marriage to Princess Rhaenys keeps him close to the action, meaning we can probably expect to see quite a bit from actor Steve Toussaint during House of the Dragon season 1. BUT prolific actor of enormous caliber, Toussian has had a long career in television and film. Those who are familiar with British television will recognize him in particular from The Silence, as well as from Doctor Who.
Constant work since the late 90s gives him the opportunity to gain a lot of experience. This extends to American television, with a role in several episodes of CSI: Miami. But perhaps his most recognizable contribution is the Hollywood film Prince of Persia: The Sands of Time. Adapted from the video game of the same name, the film was directed by many famous actors such as Jake Gyllenhaal, Gemma Arterton and Ben Kingsley. As a sumptuous period piece, this film was unquestionably the precursor to House of the Dragon. Tuassan plays Seso, a warrior race who joins Prince Dastan (Gyllenhaal) on his journey. We’re going to assume that Toussaint feels right at home in these elaborate costumes in House of the Dragon.
