When Game of Thrones ended earlier this year, many fans were left upset. Not just because of the prospect of a life without a weekly check-in with their favorite Westerosi, either. Many found the final season of the show to be disappointing - feeling rushed, ill-thought-through, and not faithful to the story they'd followed so far.

But it turns out that the cast actually filmed an alternative ending to the show, according to Kristofer Hivju, who played Tormund Giantsbane in the hit series.

This could have completely changed everything. Keep scrolling to get the full scoop.

Game of Thrones first aired in 2011.

It ran for an epic 8 seasons before finally reaching its conclusion earlier this year.

The show was set in the fictional world of Westeros.

And although it certainly had many fantastical aspects, it really centered around the deeply human characters.

It was really huge in scale.

The dedication showrunners put in to create believable settings and well-rounded characters (and seemingly hundreds of them) made the fantasy seem oddly believable.

Of course, there were some unbelievable aspects.

Although even the dragons seemed somehow par for the course in this epic, political drama.

The show wasn't totally original, though.

Game of Thrones was based on a series of fantasy novels called A Song of Ice & Fire, by esteemed writer George R.R. Martin.

Martin was a big name in the fantasy scene.

And he's been very productive in his time, creating many more fantasy worlds than just the famous Westeros.

It was clear Game of Thrones creators were taking the show seriously.

Because they ensured Martin was included in the show's creation, making sure the series stayed true to his original vision.

And fans appreciated it.

For the first seasons, Game of Thrones gained a cult following, many of whom loved the shows epic scale and attention to detail.

That is, until season eight.

After a two-year hiatus, the show returned for its final season earlier this year - but got distinctly mixed reviews.

And let's not even get started on the show's finale.

Many Game of Thrones fans were bitterly disappointed in the way the fates of their favorite characters (and of Westeros overall) were handled.

In fact, fans were pretty annoyed.

Angry Game of Throners created a "Remake Game of Thrones Season 8 with competent writers," which picked up more than 1.7 million signatures.

The main 2 people fans were annoyed at?

Show creators, David Benioff and D.B. Weiss. The petition read, the two "have proven themselves to be woefully incompetent writers when they have no source material (i.e. the books) to fall back on."

Fans felt the two had ruined what Martin had started.

"This series deserves a final season that makes sense. Subvert my expectations and make it happen, HBO!"

But the show's stars reacted pretty poorly.

Jon Snow (or Kit Harrington) told Esquire, "How I feel about the show right now is quite defiant. I think no matter what anyone thinks about this season - and I don't mean to sound mean about critics here - but whatever critic spends half an hour writing about this season and makes their [negative] judgment on it, in my head they can go **** themselves."

And that's not all.

"I know how much work was put into this. I know how much people cared about this. I know how much pressure people put on themselves and I know how many sleepless nights working or otherwise people had on this show. Because they cared about it so much. Because they cared about the characters. Because they cared about the story. Because they cared about not letting people down," he ranted.

Harrington wasn't the only one.

Sophie Turner, wife of Joe Jonas and actress behind Sansa Stark, also called the petition "disrespectful."

But, it turns out that the cast actually filmed an alternative ending to the show.

Kristofer Hivju, who played Tormund Giantsbane in the hit series, revealed the game-changing revelation during an interview with Metro this week.

"Well, we shot an alternative ending."

"That was mostly for fun but I don’t know if I’m allowed to tell you about that," he joked. It was previously reported that the show was filming multiple endings to confuse paparazzi and fans, and therefore prevent any spoilers leaking. But Hivju appears to confirm that this was indeed true.

What could this have meant for the fate of the characters?

 Sadly, Hivju couldn't share which actors were involved in the alternate finale, which could've revealed whether a different set of characters were meant to survive or not in the alternative version.

"I won’t tell you!" the actor joked. "But it was fun."

So it seems we won't be getting a glimpse of the alternative ending...
