White Walkers invade the streets of London ahead of next 'Game of Thrones'

It's winter in July on the streets of London.

Londoners casually going about their business yesterday might have looked up from their phones to see a terrifying sight -- a band of White Walkers trolling the city. Thankfully, they weren't out for blood. They were there to promote the season premiere of Game of Thrones.

The Night King and his minions toured some of London's most popular sites to get people hyped about what is sure to be an epic seventh season. Five actors spent four hours being transformed into White Walkers for the stunt, and it took over eight weeks to create the full costumes, according to Sky Atlantic.
