If you're like every other person (besides me) you watched every single second of "Game of Thrones" on Sunday. You actually saw Chris Stapleton on this past episode and probably didn't even realize it.
He played a Wildling-turned-White-Walker (I don't even know what the means, yet!) and there was a brief shot of him on the ground as Jon Snow attempts to charge the Night King outside of Winterfell. Chris Stapleton's wife, Morgane, posted the scene on Instagram.
He talked about how it happened:
"They knew we weren't actors, So the direction was basically, 'we're going to place you, and when we tell you to, open your eyes.' And they trained us on how White Walkers are supposed to stand up and move when they're first waking up. We had a crash course in that."
Stapleton's bass player and tour manager were also in it.
