Game of Thrones is one of the most epic shows on TV. Whether you love it for the intense, twisty story lines, the beautiful sets and costumes or the stunning CGI, it's a show which truly offers something for everyone.

Something that all Game of Thrones fans can agree on is that they do a good battle scene. The monumental fight scenes often combines many of the things that make the show so great - twists, turns, gory injuries and out-of-the-blue deaths of beloved characters. They're basically what Game of Thrones does best.

As the show draws to its conclusion, there's one big battle left to be seen. And rumors have surfaced that it'll be like nothing fans have ever seen before. The upcoming Battle of Winterfell is set to be the longest the show has ever depicted, taking place over the course of a whole episode. We cannot wait to see what happens and now they've dropped a trailer to give us a little taster!

Based on the best-selling book series "A Song of Ice and Fire," by George R. R. Martin, the show began in 2011 and has grown every series since.

It's set in a fantasy world, primarily in the country of Westeros.

The show cleverly blends together aspects of medieval history with wilder, fairy tale elements, plus tons of sex and violence, to create an intense viewing experience.

The general premise of the show is a battle for power.

The "game of thrones" is played by nine warring families, who all believe they have the right to be the rulers of Westeros.

And there's very little the characters of the show wouldn't do to get to where they need to be - which, as you can imagine, makes for some pretty incredible viewing.

There are many factors in the show's success.

The ensemble cast expertly depicts a range of beloved characters. The show has been praised for how nuanced and complex each of the characters are, making them seem exceptionally real, even in a world of fantasy.

The viewing experience is generally pretty epic.

Game of Thrones makes use of the most majestic scenery that exists in the real world in order to help bring Westeros to life.

Oh, there are also dragons.

As if you didn't think the show sounded insane enough, there are also giant flying lizards which breath fire. Not bad, hey?

Another thing Game of Thrones is known for?

Its amazing battle sequences. Well, with nine warring families and only swords, horses and violence to solve their problems, what did you expect?

Although naturally there are some out-of-this-world elements to these fights.

The addition of three angry dragons into the fray certainly makes the battles a little more interesting that your typical re-enactment.

There have been some amazing scenes over the show's run.

But it's now been revealed that the upcoming (and probably final) battle scene of the series will be the longest ever created - longer even that the Lord of the Rings infamous Helm's Deep sequence.

The epic battle will take place in Winterfell.

The Stark territory in the north of Westeros is a perfect setting for the battle. It's also one of the first places the malevolent forces from beyond the wall will come into contact with anyone.

Leader of these forces is the Night King.

The supernatural evil is the supreme leader and first of the White Walkers, the biggest threat the humans of Westeros face.

The scene features a ton of fan favorites.

These include Jon Snow, played by Kit Harington. The illegitimate Stark son has had a tremendous character arc through the show's series, and is now a prime contender for the throne.

Daenerys Targaryen is also included in the scene.

The Mother of Dragons will likely pose a big threat to her opponents, thanks to her ability to bring in a fire-breathing beast at her will.

Tyrion Lannister is a part of the battle, too.

The polarizing character, played by Peter Dinklage, is a fan favorite, due to his cheeky sense of humor and admirable determination in the face of adversity.

Two Starks also remain at Winterfell.

Arya, the youngest daughter, has been through a lot during her Game of Thrones journey. She's skilled with a sword, so will likely be a valuable addition in battle.

Eldest daughter Sansa Stark is there, too.

Although many disliked her for her superficiality and vanity in earlier seasons, she's proven herself to be incredibly tough, brave and well worth having on your side.

Brienne of Tarth is also a part of the sequence.

The incredible swordswoman makes for a threatening opponent, thanks to her sheer size and strength. So it looks as though there are a range of valuable members on the side of the humans.

The problem is, they're vastly outnumbered.

The sheer amount of White Walkers (plus the fact they have dark magic on their side) means the battle will be extremely hard-fought - and undoubtedly nerve-wracking viewing.

While huge crowd scenes are the show's bread and butter, this is the most major Game of Thrones characters in a scene since the show's inception. Speaking to Entertainment Weekly, Kit Harington joked, "You can’t have this many actors on set, there are too many egos!"

The creation of this battle sequence has been anything but easy.

"This final face-off between the Army of the Dead and the army of the living is completely unprecedented and relentless and a mixture of genres even within the battle. There are sequences built within sequences built within sequences," co-executive producer Bryan Cogman told Entertainment Weekly.

The shooting has largely taken place at night.

Over 11 months, the entire enormous cast and crew suffered through overnight shoots in freezing cold countryside and harsh weather conditions. The shooting experience for the Battle of Winterfell sounds exceptionally gruelling.

For Maisie Williams, who plays Arya Stark, it was her first experience with a battle sequence.

Speaking the Entertainment Weekly, Williams stated, "I skip the battle every year, which is bizarre since Arya’s the one who’s been training the most. This is my first taste of it. And I’ve been thrown in at the deep end."

Iain Glen, who plays Jorah Mormont, was even more candid.

“It was the most unpleasant experience I’ve had on Thrones. A real test, really miserable," he admitted. "You have no life outside it. You have an absolute f—ked bunch of actors."

Alongside the actors, the crew had a hard time, too.

Liam Cunningham, who plays Davos Seaworth, shared with Entertainment Weekly, “I heard the crew was getting 40,000 steps a day on their pedometers. They’re the f—king heroes."

The battle promises to be the longest sequence ever created.

The record, up until now, has been held by the forty-minute Helm's Deep battle sequence in The Lord of the Rings: The Two Towers. 

But Game of Thrones is set to easily top that record.

According to reports, the Battle of Winterfell will span an entire episode - making it up to ninety minutes of action.

As you may expect, what actually happens in the battle is being kept under wraps.

The Battle of Winterfell episode is most likely not the final episode in the series. According to Entertainment Weekly, the finale is so secretive that cast and crew had to wear a special badge to prove they had clearance to be on set.

The end of Game of Thrones has long been subject to speculation.

Wrapping up the many distinct plotlines is no mean feat. While we're hoping for a satisfactory conclusion, the show's creators are known for subverting expectations, and it seems the finale may be no exception.

All we know is, we'll definitely be tuning in. Here's the first official trailer:

The final episode seems set to be one of the most-watched television events of all time, and is expected to be viewed by tens of millions of fans when it airs on the 19th of May. Count us in!
