"A Knight of the Seven Kingdoms" is expanding its cast for Season 2.

This news comes just a week after the first season ended.
The show was already renewed for Season 2 back in November 2025 before its first season even started. The second season will be based on the second book in the Dunk & Egg series, titled "The Sworn Sword." Lucy Boynton will play Lady Rohanne, Babou Ceesay will play Ser Bennis, and Peter Mullan will play Ser Eustace Osgrey.
Lucy Boynton is represented by United Agents, CAA, and Jackoway Austen Tyerman.
Babou Ceesay is represented by The Artists Partnership, Entertainment 360, and Granderson Des Rochers. Peter Mullan is represented by Markham, Froggatt & Irwin.
The show stars Peter Claffey as Ser Duncan "Dunk" the Tall and Dexter Sol Ansell as Egg.
The story takes place about 100 years before the events of "Game of Thrones." It is based on George R.R. Martin's "Tales of Dunk and Egg" novellas.
The show received positive reviews when it first came out, with the first season getting a 94% approval rating on Rotten Tomatoes.
Both Peter Claffey and Dexter Sol Ansell were praised for their acting. Fans of "Game of Thrones" also liked the more personal storylines, shorter episodes, and the six-episode season format.
The show was created by Martin and Ira Parker, who also serve as executive producers.
Parker is the showrunner. Other executive producers include Sarah Bradshaw, Owen Harris, Ryan Condal, and Vince Gerardis.
