HBO has cast Freddie Stroma in Season 6 of Game of Thrones, Entertainment Weekly reports.
Stroma is best known for his role on Lifetime’s UnReal, though Harry Potter fans man recognize him as Cormac McLaggen from Harry Potter and the Half-Blood Prince and both parts of Harry Potter and the Deathly Hallows.
Stroma will play Dickon Tarly, the younger brother of Samwell Tarly. After Samwell took the black, the much more physically capable Dickon became heir to Horn Hill, the seat of House Tarly. While he has been mentioned, Dickon has not actually appeared in the A Song of Ice and Fire novels. His role in the events of the coming season is unknown, but Dickon and Samwell’s father, the master military strategist Randyll Tarly, is also rumored to appear.
Game of Thrones Season 6 will air on HBO in 2016.
