HBO's Game of Thrones prequel, A Knight of the Seven Kingdoms, has added three new actors to its season two cast. Lucy Boynton, Babou Ceesay, and Peter Mullan have been cast as Lady Rohanne of Coldmoat and Ser Eustace Osgrey of Standfast in the Reach. The second season will be based on George R.R. Martin’s novella The Sworn Sword and is expected to film in Spain. Showrunner Ira Parker previously stated that the season two will still be six episodes and the budget has remained unchanged, but inflation has led to more production costs. The Knight will return for season two sometime in 2027.
