Here’s How ‘Game Of Thrones’ Filmed The Epic Battle At Hardhome

What happened at the end of Sunday’s Game of Thrones had to look great. In a way, the whole show had been leading up that battle; the very first scene in the very first episode is about the White Walkers, the ultimate threat to every living character in Westeros. Thankfully, not only was it visually fantastic and emotionally resonant, but a huge ratings success.

HBO released a making-of video of how “the most intense 15-minute sequence,” according to co-showrunner David Benioff, was put together. It’s damn impressive, with a reliance on practical effects rather than glitchy CGI. Also, TIL: Wun-Win is played by the same actor, Ian Whyte, as Gregor Clegane No. 2. He’s very tall.
