The stars of HBO’s new Game of Thrones spin-off A Knight of the Seven Kingdoms were on hand at the CCXP convention in São Paulo, Brazil, today to promote the upcoming series. And during the chat, the show’s star Peter Claffey, who plays Ser Duncan the Tall, aka Dunk, seemed to let loose an interesting bit of George R.R. Martin trivia.
When asked by the panel moderators if he or his young co-star Dexter Sol Ansell (who plays Prince Aegon Targaryen, aka Egg) have gotten to meet the famed author of the A Song of Ice and Fire novels. Claffey explained that Martin visited the set during filming, and when he did he told the actor what his favorite story is that he’s written.
“It was awesome,” said Claffey. “He came in to set that week and we got to talk to him and different things, and he told us that The Hedge Knight is his favorite thing he’s ever written.”
The Hedge Knight is the first novella in Tales of Dunk and Egg, which is the collection of three novellas that A Knight of the Seven Kingdoms is based on. Published in 1998, The Hedge Knight was followed by The Sworn Sword in 2003 and The Mystery Knight in 2010.
“So he kind of told Ira Parker, our showrunner and writer, ‘Please don’t mess it up,'” added Claffey, much to the amusement of the CCXP crowd. “But he seemed really happy with us and with everyone else, and especially Daniel Ings, who’s playing Ser Lyonel Baratheon.”
“And he’s hilarious,” added Sol Ansell of Ings’ performance.
A Knight of the Seven Kingdoms will be the second Game of Thrones spin-off to make it to the air after House of the Dragon, and will debut on January 18, 2026, on HBO. A second season is already planned, with production starting next week. Indeed, Sol Ansell’s already got his head shaved for the shoot!
A new trailer for the show also debuted at the panel, which you can watch below:
