Join NowThe Game of Thrones universe just got a whole lot more exciting. Hot on the heels of a smash Season 1 finale, HBO’s A Knight of the Seven Kingdoms has officially cast Peter Mullan, best known for Ozark, in its upcoming second season — and fans are already losing their minds over it.
So, What Role Will Peter Mullan Play?
Here’s the big question everyone’s been asking: what role will Peter Mullan play in A Knight of the Seven Kingdoms? The veteran actor has been tapped to play Ser Eustace Osgrey of Standfast in the Reach — a grizzled, landholding knight who is set to shake up the world of Dunk and Egg in a major way. It’s the kind of role tailor-made for Mullan’s trademark intensity, and frankly, we couldn’t imagine better casting.
What Is Season 2 All About?
The second season adapts George R.R. Martin’s novella The Sworn Sword, the second book in the Dunk & Egg series. The story sees Dunk and Egg entangled in a regional dispute during a brutal summer drought in Westeros — and Ser Eustace is right at the heart of that conflict.
Mullan joins returning stars Peter Claffey as Ser Duncan “Dunk” the Tall and Dexter Sol Ansell as Egg, who was revealed in Season 1 to be none other than Prince Aegon Targaryen.
He won’t be the only fresh face. Lucy Boynton (Bohemian Rhapsody) joins as Lady Rohanne of Coldmoat, also known as the Red Widow, while Babou Ceesay (Alien: Earth) steps in as Ser Bennis of the Brown Shield. The trio promises to bring serious dramatic firepower to what is shaping up to be an unmissable season.
Why the Hype Is Very Real
Season 1 proved the show is no mere spin-off — it’s a genuine phenomenon. The Season 1 finale pulled in 9.5 million U.S. viewers in its first three days, with viewership surging 42% from the premiere. The momentum is undeniable.
Season 2 is expected to arrive in 2027 — a remarkably fast turnaround by modern TV standards, with production having already kicked off back in December.
The Realm is waiting, and Peter Mullan is ready to ride.
