A Knight of the Seven Kingdoms, a new prequel to Game of Thrones premiering on HBO on January 18th, 2026, has revealed its first official trailer.
The story follows Ser Duncan the Tall (Peter Claffery), a lowly hedge knight who happens to be — surprise — very, very tall. He sets out for the town of Ashford and is eventually accompanied by a young boy, Egg (Dexter Sol Ansell), who becomes his squire. While there, Duncan is put to the test in a tournament, with Prince Aerion Targaryen (Finn bennett) rivaling the hedge knight. The series takes place nearly 100 years before the events of Game of Thrones, and nearly 100 years after the events of the ongoing prequel series, House of the Dragon. Watch the trailer below.
Based on George R.R. Martin’s Tales of Dunk and Egg novellas, the official logline for A Knight of the Seven Kingdoms reads: “A century before the events of Game of Thrones, two unlikely heroes wandered Westeros… a young, naïve but courageous knight, Ser Duncan the Tall, and his diminutive squire, Egg. Set in an age when the Targaryen line still holds the Iron Throne, and the memory of the last dragon has not yet passed from living memory, great destinies, powerful foes, and dangerous exploits all await these improbable and incomparable friends.”
