<P> Many of the scenes leading up to the battle with the White Walker army were filmed in Iceland , but the majority of the episode 's battle sequence was filmed in a quarry in Belfast , Northern Ireland . Taylor had expected to film the sequence entirely in Iceland , but quickly realized that it was not feasible due to the amount of production that was required . In filming the wight polar bear attack , Taylor noted that the bear was designed by the New Zealand - based Weta Workshop , which previously worked on The Lord of the Rings trilogy . Richard Dormer , who portrays Beric Dondarrion , described filming the scene in a separate interview , saying `` It was very cold , wet and physical . Hot as well , running around imagining a 12 - foot flaming polar bear . It 's pretty weird , but it was fun . '' Dormer also noted the difficulty of filming a flaming sword , revealing that the sword could only burn for two minutes at a time , and could not be swung too quickly , requiring Dormer to slow down his movement . He also said that the sword he was using weighed approximately three times more than a normal sword . Though the actors were dressed warmly for the scenes beyond the Wall , their suits contained a `` tube system through which cold water can be circulated between shots using a portable pump to keep them from getting overheated , '' due to the actual warmth of filming on a fake set in Northern Ireland . This was also essential due to the possibility of Rory McCann 's , who portrays Sandor `` The Hound '' Clegane , prosthetic makeup melting off his face . </P>
