House Of The Dragon: Breaking Down Each Announced Cast Member

10. Graham McTavish

The most recently announced cast member is yet to be confirmed by HBO officially, but was revealed by the actor himself. No details yet exist on who Graham McTavish will be playing or even if he'll feature in any meaningful or extended way.

That being said, McTavish is no stranger to genre storytelling and will hopefully have an expansive role on the prequel series. From one of the dwarves in The Hobbit trilogy to the vicious Saint of Killers in Preacher, McTavish has a tendency to dress up in fantasy costumes and partake in high amounts of violence.

Most recently, the actor was cast in Season Two of Netflix's The Witcher as Sigismund Dijkstra which positions McTavish to appear in two of the most high budget and anticipated fantasy shows currently being worked on. With an appearance in a Tolkien adaptation already under his belt, McTavish is one of the most used Fantasy actors working today.
