Bet You Didn't Spot This Grammy Winner's Cameo in Game of Thrones' Battle of Winterfell

The Battle of Winterfell was brimming with wights, knights, and every other kind of fighter, so you'd be forgiven for missing country music superstar Chris Stapleton's face on the field -- but he was there.

On Monday, the Grammy winner shared a behind-the-scenes shot of himself in his wildling gear on the set of Sunday's episode of Game of Thrones, "The Long Night." Stapleton can be seen onscreen when the Night King reanimates a bunch of Winterfell's own dead soldiers as Jon Snow (Kit Harington) tries to sneak up on him.

Speaking to Rolling Stone, Stapleton explained that he had asked his management team to try to get him a part on the HBO drama since he's such a huge fan. "I was like, you know, I would gladly fly to wherever in the world just to be a small part and get to watch that show going down," he said. "They were gracious enough to let me come participate that way."

Stapleton wasn't the only big name with a bit part on Game of Thrones this week, either. The esteemed Spanish monster actor Javier Botet -- who's played all manner of creepy humanoid creatures in films like Mama, It, and Slender Man -- also appeared in the tense scene in which Arya Stark (Maisie Williams) slinked through the library.

Botet portrayed the walker that very nearly found her under the table after she took cover. HBO's behind-the-scenes feature on the episode reveals that he was hand-selected for the role thanks to his double-jointedness and resulting ability to do "ridiculous things with his body," as well as his familiarity with wearing the kind of prosthetics necessary to make him look so creepy.

Game of Thrones airs on Sundays at 9/8c on HBO.
