Game of Thrones episode three trailer teases the show's biggest battle EVER

The new trailer for the third episode of Game of Thrones’ final season gives fans a first look at the show’s biggest battle yet.

The teaser clip shows the likes of Jon Snow (Kit Harington), Sansa Stark (Sophie Turner) and Brienne of Tarth (Gwendoline Christie) preparing to face down the Night King’s forces in the Battle of Winterfell, the epic clash between the forces of the living and the dead.

“The most heroic thing we can do is look the truth in the face,” Turner’s character says at the start of the trailer, before her on-screen brother Harington – in a twist on one of the show’s most famous lines – warns that “the Night King is coming.”

HBO has confirmed that the third episode, which required 11 weeks of arduous night shoots, will be the longest in Game of Thrones history, lasting 82 minutes.

Discussing the episode ahead of the new season, actress Maisie Williams told Entertainment Weekly that she was left feeling “mentally and physically broken” after filming the battle scene.

Williams, who plays Arya Stark on the HBO show, said: “Nothing can prepare you for how physically draining it is.

“It’s night after night, and again and again, and it just doesn’t stop. You can’t get sick, and you have to look out for yourself because there’s so much to do that nobody else can do.

“There are moments you’re just broken as a human and just want to cry.”

Iain Glen, who plays Ser Jorah Mormont, described the shoots as “the most unpleasant experience I’ve had on Thrones.”

“A real test, really miserable,” he told the publication. “You get to sleep at seven in the morning and when you wake in the midday you’re still so spent you can’t really do anything, and then you’re back. You have no life outside it.”

Game of Thrones airs on Sky Atlantic on Mondays at 2am and 9pm and is available to stream on NOW TV.
