Game of Thrones co-showrunner David Benioff said the episode will follow several different characters as the battle rages on.
Benioff explained these bits mix things up, and why an entire episode was needed for the big showdown.
Miguel Sapochnik’s episode was originally said to have used 55 nightshoots, but EW reported the shoot continued at an indoor location for weeks beyond that.
Part of that was the crew making sure they got the scenes right, but also the episode’s complexity.
