The world of Westeros is full of twists, but sometimes the biggest drama happens off-screen. Peter Claffey, the Irish star playing Ser Duncan the Tall in HBO’s hit series A Knight of the Seven Kingdoms, has finally given a straight answer to fans who keep asking about Henry Cavill joining the show for Season 2.
For months, rumors spread like wildfire across social media. Fans of the “Game of Thrones” prequel were convinced that the former Superman and “The Witcher” star was going to show up in the second season. But Claffey recently set the record straight in the most direct way possible. He made it clear that the Man of Steel is not coming to the Seven Kingdoms.
How A Simple Joke Turned Into A Massive Casting Hoax
The confusion all started during an interview at New York Comic-Con. Peter Claffey was describing his character, Dunk. He jokingly called Dunk a “less sexy, less confident, less charismatic Geralt of Rivia.” For those who don’t know, Geralt is the monster hunter played by Henry Cavill in Netflix’s “The Witcher.”
While Claffey was speaking, his young co-star Dexter Sol Ansell (who plays Egg) tried to add to the joke. He started to say, “Do you think you can say that Henry Cavill…?” But Claffey cut him off before he could finish. That small moment of silence was all the internet needed to start guessing.
Fans immediately thought Dexter had accidentally spoiled a secret. Social media exploded with posts claiming that Henry Cavill had already signed on for A Knight of the Seven Kingdoms Season 2. The rumor grew so big that Claffey had to step in and stop the false news.
The Dublin Comic-Con Confession
The truth finally came out when Claffey and Ansell appeared together at Dublin Comic-Con in March 2026. This time, the young actor let the star handle the explanation. Claffey told the audience exactly how the wires got crossed.
He explained that during the audition process for the role of Dunk, he was competing against another actor. Claffey joked that this other person was much more charismatic than him. He said he was happy that actor was busy doing something else, which allowed Claffey to land the part of the tall knight.
The problem happened when young Dexter Sol Ansell misheard the story. He mixed up the unnamed actor with Henry Cavill. Dexter assumed that Claffey had “beaten” Cavill to get the role.
“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
To make sure no one left the room confused, Dexter jumped in with a clear punchline. He looked at the crowd and said, “So, anyway, Henry Cavill is… NOT in the second season!” The audience laughed, but for fans holding out hope, this was the final confirmation.
A Wish, Not A Reality
Even though Henry Cavill isn’t joining the cast, Peter Claffey admitted he is a big fan of the actor. During the same panel, Claffey shared his own hopes for Cavill’s future in the “Game of Thrones” universe.
He suggested that Henry Cavill would be perfect to play Aegon the Conqueror in the upcoming movie adaptation. Claffey made it clear that he has no secret information from HBO. He was just sharing a personal wish.
“I would pay a lot of money to see that.” – Peter Claffey on wanting Henry Cavill to play Aegon the Conqueror
This was Claffey’s way of saying that while Cavill isn’t coming for Season 2, the door is always open in the actor’s mind for the future.
What Is Actually Happening In Season 2
While the Henry Cavill rumor is false, there is a lot of real news about A Knight of the Seven Kingdoms Season 2. The show has already been picked up by HBO. Filming is currently happening, and the new season is expected to arrive in 2027.
The second season will follow the second book in George R.R. Martin’s series, titled “The Sworn Sword.” The story moves away from the tourney grounds. Dunk and Egg will travel to a region called the Reach. There is a big drought, and water is scarce. Dunk gets caught in a fight between two stubborn lords.
The cast is also growing. New actors joining the show include Lucy Boynton (Bohemian Rhapsody) as the Lady Rohanne Webber, also known as the “Red Widow.” Babou Ceesay and Peter Mullan are also part of the new season.
Showrunner Ira Parker says Season 2 will feel different. “It’s going to be a different season, and, I hope, for the better,” Parker told The Hollywood Reporter.
Peter Claffey Gets A Hair Makeover
There is one more small but important change coming for Peter Claffey in the new season. Fans of the books noticed that Dunk is supposed to have long, shaggy hair. In Season 1, Claffey had short hair.
The actor confirmed that for Season 2, he has grown his hair out. He stopped cutting it at the end of filming the first season, hoping he would get the call to come back. Now that Season 2 is real, Dunk will finally look like the character from the pages.
“I feel like other than Dunk not having long hair, it’s pretty bang on.” – Peter Claffey comparing Season 1 to the books
The showrunner, Ira Parker, is working hard to keep the show close to George R.R. Martin’s vision. Parker revealed that Martin himself insisted on accuracy. “George repeated this phrase to me seven times in the first three minutes of our meeting in Santa Fe,” Parker said.
