Sometimes the biggest casting announcements don’t arrive with epic music or dragon fire, just a kid, a phone camera, and a moment of pure disbelief. That is precisely the way fans were introduced to Egg Targaryen’s new face. Dexter Sol Ansell, a nine-year-old English actor, previously posted his response to being told that he had been cast as Aegon “Egg” Targaryen in the ‘Game of Thrones’ prequel, ‘A Knight of the Seven Kingdoms’.
The video is brief, sweet, and immediately catchy. It is one of those reminders that, behind the lore, timelines, and fandom arguments, the feeling of getting the role is magic, particularly when you are little.
The Moment Dexter Sol Ansell Learned He Would Play Egg

Ansell is not new to large franchises, even at his age. He might be known to the audience as a young Coriolanus Snow in ‘The Hunger Games: The Ballad of Songbirds and Snakes’, a character who demonstrated that he was capable of dealing with emotionally charged content.
In the video he shared, there’s a split second of disbelief before it hits him, and then everything spills out at once: wide eyes, laughter, that barely-contained excitement that only happens when a dream suddenly becomes real. It doesn’t feel staged or polished; it feels like a kid realizing his world just got a lot bigger. Still, entering Westeros is another monster altogether.

Why Egg’s Appearance Is Central To ‘A Knight Of The Seven Kingdoms’

Egg is not a comic relief or a precocious kid who is riding along. He is Prince Aegon Targaryen, future King Aegon V, traveling incognito to understand the realm he may one day rule. His bald head, or rather his shaved head, is not merely a visual joke. It’s survival. His hair is silver-blond and would give him away at a glance.
George R.R. Martin himself has mentioned that Ansell is more than willing to shave his head, and, frankly, the fact is on brand.

Egg is pragmatic, obstinate, and ready to forego comfort in favor of a greater cause. A boy eager to get rid of the wig chair? That’s commitment. Above all, Ansell’s happy reaction makes the fans remember why Egg is a favorite character.
Egg is a boy on the road, learning and growing, before crowns and rebellions, and before family trees turn into tragedy. And now a new generation has the privilege of growing with him.
