Production on HBO’s upcoming Game of Thrones spinoff, A Knight of the Seven Kingdoms, has kicked off in Belfast, Ireland, and we’ve already got a good look at its star, Peter Claffey. This first image from the series reveals little about what to expect, as it mostly shows us an early look at Claffey as Ser Duncan the Tall as he towers over a crowded street. We have yet to get a look at his co-star, Dexter Sol Ansell, who will play Egg in The Hedge Knight adaptation.

“A century before the events of ‘Game of Thrones,’” the official logline says, “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." Claffey and Ansell will star alongside one another when the series eventually premieres, and today’s news also comes with a few of the other faces that will be joining them.

HBO says the newly revealed cast includes Finn Bennett (True Detective Season 4, The Nevers) as Aerion Targaryen, Bertie Carvel (Dalgliesh, Doctor Foster: A Woman Scorned) as Baelor Targaryen, Tanzyn Crawford (Swift Street, Servant) as Tanselle, Daniel Ings (The Gentlemen, The Crown) as Ser Lyonel Barotheon, and Sam Spruell (Legend, Snow White and the Huntsman) as Maekar Ta.
