Stunt coordinator Rowley Irlam said the shoot required stunt skills that Maisie Williams had learned through the entire series. "We shot that on location, and it was very, very cold and wet," he said. "It’s a really awkward place because it’s kind of boggy there, so you can only get cranes so far into the location. It was successful; however, it wasn’t as sharp as we wanted. We wanted the connection of the two characters to be, you know, they’re locked into each other. She into him, and him into her. And so we redid it on the stage because we just weren’t that happy with the end result." Was any CGI used? "No, it was an assisted jump and an assisted arrest, but what you see of her coming through the air and landing on Vlad, the Night King, is real and all on camera."
