'Game of Thrones': White walkers take over London in advance of season 7

— -- Winter has apparently arrived a few days early in London.

In advance of "Game of Thrones" season 7, the network Sky Atlantic, which airs the show in the United Kingdom, paraded out an array of White Walkers in the heart of London earlier this week.

The network shared videos and pics Wednesday and today of the whole ordeal.

"(white) WALK(er) THIS WAY!" they captioned a picture from yesterday.

The actors, dressed to the nines, went everywhere, including Buckingham Palace.

"Look out U.K. because #WinterIsHere! From Buckingham Palace to Hadrian's Wall, the White Walkers are EVERYWHERE," the network added in a video.

In the show, the White Walkers are bearing down on the regular folk in Westeros and the different factions might have to unite against them. They are led by the Night King, also seen in the video on horseback.

According to Business Insider, each actor spent four hours in makeup for the promotion.

"Thrones" comes back to HBO in the states and Sky Atlantic in the U.K. July 16 and 17, respectively.
