Watch: Game Of Thrones Epic "Hardhome" White Walker Battle

Sunday’s episode of Game Of Thrones saw an epic battle take place between the army of the White Walkers and the free men of the North in addition to Jon Snow and his Crows.

The episode was the best of the season to date (finally), with the battle lasting almost twenty minutes long.

Kit Harington, who plays Jon Snow, told Huff Post the scene took two weeks to film with the cast and crew “cold and wet” as they “painstakingly filmed the scene amid terrible conditions.”

“All the money on ‘Thrones’ is spent on the actual sequence or finishing the thing. None of it’s spent on the actors’ luxury. So we had this tiny cast tent with a river running through it, which is fine,” Harington said. “You just muck in with ‘Thrones.’ It was great.

“The really amazing bits were the bits where you said, ‘Okay, now this giant is going to burst out of the hut, and then all these undead are going to fall off the cliff,’ and those are the bits you obviously can’t see. So you kind of really geek out about that stuff, and then getting to watch it afterward is really, really amazing,” he said.
