The second episode of Game of Thrones Season eight provided viewers with a calm before the impending storm that is the undead army approaching Winterfell. That means that episode three of the final season will feature the long-awaited Battle of Winterfell, which HBO has been teasing ever since the season entered production. The sequence, which took 55 nights to film, will finally air this Sunday.

To whet the appetite of those eagerly anticipating the epic battle, HBO has teased it even further with a series of stills via Entertainment Weekly. The episode is set to run for a whopping 82 minutes, making it the longest of the entire series.

The newly released pictures showcase Jamie Lannister and the newly-knighted Brienne preparing to fight the White Walkers, Jon Snow looking particularly worried, Sansa and Arya Stark atop the castle, and Tyrion Lannister and Varys hanging out below in the crypts. Check out all of the stills below.

While the images don't give too much away ahead of Sunday, they do suggest that Winterfell isn't quite prepared for the army that approaches. We'll find out when the buggest episode in GoT airs this Sunday. HBO previously released a preview of the episode, and it looks to be just as huge as promised. Watch below.
