Game of Thrones fans have been curious about what the resurrected, Frankenstein's monster-like killer Gregor "the Mountain" Clegane (Hafþór J Björnsson) looks like underneath his helmet since he first came back in Season 5. All that could be seen of his face were his bloodshot eyes the bluish, dead-looking flesh around them.

At least until the Season 6 finale, when we finally saw him without his helmet. The moment was brief and the lighting was too dark to really make out his face, but whatever he looked like, he made Septa Unella (Hannah Waddingham) scream in terror.

Now, we finally, clearly know, and it's just as disgusting as we imagined. Björnsson tweeted a behind-the-scenes photo of himself in Zombie Mountain makeup, and, well, he looks like a putrefying corpse.

His ladyfriend must really love him a lot to be able to kiss that nightmare face.
