Real battle of ‘Game of Thrones’ is constant fight against spoilers

Never has a potential haircut received so much attention.

On “Game of Thrones,” Kit Harington, and his thick mane of black hair, plays Jon Snow, a central character who many fans think may be killed off. The show’s fifth season, in fact, ended with Snow being stabbed multiple times. The final shot showed his blood staining the snow. The camera cut away, with the audience not knowing if he’s been killed or merely injured.

The answer to that question — Did Jon Snow die? — was so carefully guarded that co-showrunner D.B. Benioff reportedly even refused to tell his wife.

During the next year, fans kept close watch on Harington’s whereabouts. They also kept track of his hair length (Snow has long hair), tying to figure out if he was filming a new season.

Learning from the experience, the GoT crew reportedly filmed decoy scenes when filming season 7, which premiered July 16.

“We did fake some scenes,” Harington said to Jimmy Kimmel during a recent appearance on his show. “We put together people in situations where we knew the paparazzi was around so they’d take photos, and that would get on the internet to fake scenes.”

Arguably no show works harder to avoid spoilers. The producers of “Game of Thrones” guard its plot points with the same fervor the show’s characters chase that coveted iron throne, a defense The Ringer’s Andrew Gruttadaro called “near pathological.”
