25 actors you forgot were on Game of Thrones

10. Ross Mullan

Number of episodes: 3

Character name: White Walker

Everyone knows the White Walkers, but almost no one knows who played them. Ross Mullan played various White Walker on three episodes on the series between seasons 2 and 4. Under all that makeup, there was little chance of recognizing him.

Obviously, the White Walkers were important to the story. They didn’t say anything and they barely showed up on the screen until closer to the end, but they were always a threat. Let’s not talk about what became of them in that final season.

Mullan is one of those actors who plays a lot of these mysterious creatures on sci-fi and fantasy shows. One that you might know best is Silent on Doctor Who. Mullan played that role in the episode “The Time of the Doctor.” He would then show up as two other characters on the series, because when you have a lot of makeup, you get away with playing multiple roles without anybody realizing.
