Rumors had circulated that actor Henry Cavill would be joining the cast of the 'Game of Thrones' prequel series 'A Knight of the Seven Kingdoms' for its second season. However, the show's stars Peter Claffey and Dexter Sol Ansell have now officially shut down those rumors, explaining that the speculation stemmed from a misunderstanding during a convention appearance.

Why it matters

Cavill is a popular fan-casting choice for various 'Game of Thrones' universe roles, so the prospect of him joining the prequel series had generated significant excitement among fans. The clarification from the show's cast helps put an end to the unfounded speculation.

The details

The rumor originated when Claffey mentioned going up against another actor while auditioning for the role of Ser Duncan the Tall. Ansell apparently mixed up that unnamed actor with Cavill, leading fans to believe the 'Witcher' star was set to join the show. However, Claffey and Ansell have now confirmed that Cavill is not and was never planned to be part of 'A Knight of the Seven Kingdoms' season 2.

  • In February 2026, Claffey tried to shut down the rumor on his Instagram Stories.

What they’re saying

“Just to clarify, the thing Dex was referring to in the interview had nothing to do with Henry Cavill coming into the show or the GOT universe (I wish!). Complete misunderstanding.”

— Peter Claffey, Actor

“Dexter mixed up those two people, and he thought that it was Henry Cavill that I had 'beaten' to play Dunk, which would never happen anyway. So, that's what he was saying in New York, and everybody then just assumed that Henry Cavill's going to be in season 2.”

— Peter Claffey, Actor

“So, anyway, Henry Cavill is... NOT in the second season!”

— Dexter Sol Ansell, Actor

The takeaway

This clarification from the 'A Knight of the Seven Kingdoms' cast helps put an end to the unfounded speculation around Henry Cavill's potential involvement in the 'Game of Thrones' prequel series, demonstrating the importance of actors addressing casting rumors directly.
