It’s been revealed a while ago that the upcoming season of Game of Thrones is going to have an epic battle, and now we have some more details about it. Episode director Miguel Sapochnik, who also worked on season 6’s Battle of the Bastards, confirmed in an interview that this upcoming battle will be between our familiar characters and the undead army led by the Night King.

In this battle, characters like Daenerys Targaryen, Jon Snow, Sansa & Arya Stark, and Brienne of Tarth will have to face these supernatural enemies at a number disadvantage. It is described as the "longest consecutive battle sequence ever committed to film."

Co-executive producer Bryan Cogman said that the epic battle is unlike anything that has been done before in the history of TV or movie. He is confident that it will “blow everybody away”.

Filming this episode required up to 750 members of the cast and crew to work all night in sub-freezing temperatures for nearly 3 months. Maisie Williams, the actress who portrays Arya Stark, described the experience as “physically draining”. "There are moments you're just broken as a human and just want to cry," she said.

Iain Glen, who portrays Ser Jorah Mormont, shared a similar sentiment, saying that it was “really miserable” and “the most unpleasant experience” he had ever had during the entire series. He shared that the filming process was days after days of going to sleep at 7 in the morning and waking up at midday, being so tired to the point where he couldn’t really do anything else.
