‘Game of Thrones’ actors struggle to recognize their co-stars’ butts

The actors on Game of Thrones may know the show inside and out, but how well do they know the naked truth?

At the show’s season 6 premiere, PopSugar asked several actors to identify the character or actor from a shot of their backside, and it’s a lot harder than it looks. With poor lighting, ambiguity, and difficult character names to remember, many of them struggled to guess the butts of their costars. In the case of one actor, he was unable to identify his own butt, which is at least understandable since he rarely sees it.

Whose butt will get to sit on the iron throne? That’s a question for another time—but chances are we might have already seen it.
