Peter Claffey is best known as Ser Duncan the Tall in HBO’s A Knight of the Seven Kingdoms, a role that redefines what a fantasy lead can look like. His performance is built on restraint rather than bravado.
Before acting, Claffey was a professional rugby player. The discipline of that world still informs how he works—quiet focus, physical awareness, and patience. When rugby ended, acting offered a different kind of challenge.
His early screen work placed him inside ensemble productions where scale mattered more than spotlight. That experience prepared him for Westeros. As Dunk, Claffey brings moral weight rather than spectacle. The performance resonates because it feels human inside a heightened world.
Off screen, he maintains a reserved public presence and keeps his personal life private. The attention stays on the work. With HBO backing a long-term series, Claffey’s rise feels steady, intentional, and sustainable.
