HBO’s new trailer for A Knight of the Seven Kingdoms shows the titular knight promising Prince Baelor Targaryen that he’ll show him just how good a knight he is. And, although he’s dressed as a simple farmer, he knows how to handle himself in combat.

Daniel Ings plays Ser Lyonel Baratheon, Bertie Carvel is Baelor Targaryen, Danny Webb is Ser Arlan of Pennytree, Sam Spruell is Maekar Targaryen, and Shaun Thomas is Raymun Fossoway. Finn Bennett plays Aerion Targaryen, Edward Ashley is Ser Steffon Fossoway, Tanzyn Crawford is Tanselle, and Henry Ashton is Daeron Targaryen.
Youssef Kerkour is Steely Pate, Tom Vaughan-Lawlor plays Plummer, and Daniel Monks is Ser Manfred Dondarrion.
“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,” reads HBO’s synopsis. “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.”
Season one premieres on Sunday, January 18, 2026 at 10pm ET/PT. In November, HBO officially announced the newest entry in the Game of Thrones franchise has been renewed for season two.
Author George R. R. Martin and Ira Parker are the co-creators and serve as executive producers, with Parker guiding the series as showrunner. Sarah Bradshaw, Owen Harris, Ryan Condal, and Vince Gerardis also executive produce, and Harris and Sarah Adina Smith direct season one episodes.
