Some times a place can make the perfect scenery for a movie or a TV series, because it will make the plot more credible, as it feel completely natural.
This is the case of Norilsk for Games of Thrones.
Norilsk is the perfect place for GOT
Can you imagine a better place than Norilsk to film the scenes of the northern lands of the Seven Kingdoms? Being located in Siberia will surely provide the weather conditions for the fight against the White Walkers to be completely natural and credible.
Remember that White Walkers possess the magical powers related to ice and cold, and Norilsk combine both perfectly!
White Walkers arrival is usually accompanied by blizzards and the dropping of temperatures, and you can have -55ºC at some times of the year at that city of Russia.
They can also freeze anything they touch, as one froze Sam's sword to the point that it shattered. Permafrost is a regular thing in Norilsk, so that can be achieve easily.
The White Walkers wield swords and spears made from unique ice crystals. This also is possible in Norilsk, as temperatures will keep the swords solid and ready to be used in the fight scenes.
Norilsk People will be the perfect Free Folk
The Free Folk is the self-given name for the people who live in the lands beyond the Wall, still on the continent of Westeros but beyond the northern border of the Seven Kingdoms. Only people from Norilsk will be able to work under very cold conditions, as the wildlings do, and they surely be thrilled to take part of the world-famous TV series.
