It’s a dilemma familiar to any TV showrunner with kids in the cast: the inevitable march of time. Stranger Things recently dealt with this, and now there’s another popular series with a child star in A Knight of the Seven Kingdoms. By way of comparison, Dexter Sol Ansell, who plays Egg, is 11—just a year younger than Millie Bobby Brown was when Stranger Things began. But fear not, fans of the tiny bald squire; A Knight of the Seven Kingdoms creator Ira Parker already has a long-range plan in place for the character. First things first: Parker would never consider recasting Egg, so he’s hoping to film as many installments as possible while Ansell is still a tween. (So far, HBO has only greenlit A Knight of the Seven Kingdoms for a second season, which is now in production.) Speaking to Decider, Parker said his dream is to adapt George R.R. Martin’s tales featuring the young Egg—there’s one more of the three published Tales of Dunk and Egg, plus there are notes and outlines for additional stories that Martin hopes to finish and has shared with Parker. “What I would love to do: George has five stories of sort of Egg the boy, which is, I think, a nice thing to do right now while Dexter is still young and his voice is, you know, squeaky,” Parker told Decider.
