Despite traipsing through some of the world’s most formidable climates, for the sake of giving Game of Thrones its undeniable edge as one of modern media’s best scene selectors, we are drawn to the fact that Jon Snow never wears a hat.

Now, at first this might be pinned on the fact that a lot of the blistering cold effects could have been computer-generated, but Kit Harington, Game of Thrones’s King of the North, reveals the reason he doesn’t wear a hat has, in fact, been "a big, big question” on set. When filming in Iceland, and climates of similar severity, Harington is reported to have requested a hat, but as it is “very difficult when you’re filming people in that environment, to differentiate between people’s faces,” a piece of warm headgear was unfortunately vetoed.

And in the same interview with The New York Times, Harington mentions that it was “a decision they made a long time ago." "The decision that we need to see faces more than heads being warm” was decidedly “the most important thing.”
