There's just one episode of Game Of Thrones left before it goes away forever, so we're already feeling pretty damn emotional. We're talking Red Wedding levels of emotion here. But this trailer for a documentary about the HBO hit's final season has really destroyed us. We told you a few months ago about Game Of Thrones: The Last Watch, a behind-the-scenes look at the fantasy series most "most complicated and ambitious season yet". In this trailer you'll watch as all of the show's leading actors prepare for their final scenes and feel the impact of those powerful moments. We're gettin' misty already. HBO said in a statement, ‘Game of Thrones: The Last Watch delves deep into the mud and blood to reveal the tears and triumphs involved in the challenge of bringing the fantasy world of Westeros to life in the very real studios, fields and car-parks of Northern Ireland.’ While many hardcore fans of the long-running show have been disappointed with the final series, I think we can all agree we're gonna miss the shenanigans of favourites like Arya, Tyrion and Jon Snow. This documentary is all about bidding Game Of Thrones' most beloved characters a fond farewell. https://www.youtube.com/watch?v=9K7c0jXkaGc Game Of Thrones: The Last Watch premieres on May 26.
