For years, the battle between Avatar and Avengers: Endgame has been one of the biggest stories in movie history.

James Cameron’s Avatar originally became a box-office phenomenon after its 2009 release, while Avengers: Endgame appeared a decade later and seemed almost unstoppable.

In 2019, Endgame briefly became the highest-grossing movie ever, only for Avatar to eventually reclaim the crown after another theatrical re-release.

Now, in 2026, Marvel has another chance.

Following a new theatrical release, Avengers: Endgame has climbed to approximately $2.892 billion worldwide, while Avatar remains ahead with around $2.924 billion. That leaves Marvel’s blockbuster roughly $32 million away from first place.

So, can Endgame finally take the crown back?

How Did Avatar Become the Biggest Movie Ever?

When Avatar arrived in theaters in 2009, it changed the way audiences experienced blockbuster movies.

Directed by James Cameron, the film introduced audiences to the world of Pandora and became famous for its visual effects, 3D presentation, and enormous international appeal.

Its box-office performance was extraordinary.

Even years after its original release, Avatar continued to benefit from theatrical re-releases, allowing it to remain competitive with newer blockbusters.

That is an important part of the story.

The current record is not simply about what a movie earned during its original theatrical run. Additional releases can significantly change a film’s lifetime worldwide total.

Then Avengers: Endgame Arrived

Marvel spent more than a decade building toward Avengers: Endgame.

The film represented the conclusion of a massive story that began with Iron Man in 2008 and expanded across numerous Marvel Cinematic Universe movies.

The result was unprecedented audience interest.

Fans who had followed the MCU for years went to theaters to see the conclusion of the Infinity Saga.

Endgame eventually reached approximately $2.799 billion from its original release, according to Box Office Mojo.

That number was already enough to put the movie within striking distance of Avatar.

But Marvel wasn’t finished.

The 2026 Re-Release Changed Everything

The biggest development in this rivalry happened in 2026.

A new theatrical release of Avengers: Endgame generated additional worldwide revenue and pushed the movie’s lifetime total to approximately $2.892 billion. Box Office Mojo lists the 2026 re-release at more than $92.6 million worldwide.

That dramatically reduced the distance between Marvel and Avatar.

Instead of being more than $100 million behind, Endgame is now only around $32 million away from the top spot.

That makes the competition much more interesting.

Can Endgame Actually Beat Avatar?

Yes — but it isn’t guaranteed.

Endgame needs roughly another $32 million to pass Avatar based on the latest worldwide totals.

The challenge is that Endgame’s current theatrical re-release has already generated most of its immediate additional revenue.

For Marvel to reclaim first place, the movie would need either continued theatrical momentum or another opportunity to return to cinemas.

And that’s where the history of Avatar becomes important.

Cameron’s movie has repeatedly benefited from theatrical re-releases, meaning its total can also increase.

So even if Endgame passes it, the battle might not necessarily end there.

The Box Office Crown Has a Complicated History

The rivalry becomes even more interesting when looking at how the totals were achieved.

Avatar has benefited from multiple theatrical releases over the years.

Endgame originally dominated the box office after its 2019 release and is now benefiting from another theatrical run in 2026.

This means the record is constantly moving.

Box Office Mojo currently places Avatar at approximately $2.924 billion worldwide, followed by Avengers: Endgame at approximately $2.892 billion.

The difference is tiny compared with the scale of both movies.

A few years ago, the gap looked enormous.

Now, Marvel is right behind Cameron.

What Makes Endgame’s Achievement So Impressive?

The biggest advantage Endgame had was its franchise history.

The movie wasn’t simply marketed as another superhero adventure.

It was presented as the culmination of more than ten years of interconnected storytelling.

Characters such as Iron Man, Captain America, Thor, Hulk, Black Widow, Hawkeye, and many others had been developed across multiple films.

That created a unique theatrical event.

Audiences weren’t just watching a new movie.

They were watching the conclusion of a story they had followed for years.

That level of anticipation helped Endgame reach numbers that few movies in history have approached.

What Makes Avatar Different?

Avatar achieved something different.

Unlike Endgame, it wasn’t the conclusion of a massive cinematic franchise.

It introduced a completely new universe.

Pandora, the Na’vi, and the film’s visual technology became major attractions on their own.

The movie also benefited enormously from international audiences.

According to Box Office Mojo’s current figures, approximately 73% of Avatar’s lifetime worldwide gross comes from outside the domestic market.

That international strength has been one of the film’s biggest advantages.

Who Deserves the Record?

This depends on what you value.

If the question is about the biggest theatrical event created by a long-running franchise, Avengers: Endgame has an incredible case.

If the question is about creating an entirely new cinematic world that became a global phenomenon, Avatar has the advantage.

And if the question is simply about worldwide box-office revenue, the numbers currently favor Avatar.

But only barely.

Marvel vs. James Cameron

There’s also something fascinating about this rivalry.

Avengers: Endgame represents one of the greatest achievements in franchise filmmaking.

Avatar represents one of the greatest achievements in blockbuster filmmaking.

Marvel built its record through interconnected storytelling and an enormous fanbase.

James Cameron built Avatar’s success around spectacle, technology, world-building, and international appeal.

They reached the same mountain from completely different directions.

Could Endgame Become Number One Again?

Absolutely.

With the gap currently around $32 million, Endgame is close enough that another successful theatrical opportunity could potentially put Marvel back on top.

But there is one important problem.

Avatar doesn’t have to stay still.

If Cameron’s movie receives another major theatrical re-release and generates significant revenue, the target moves again.

That’s why the battle isn’t simply about whether Endgame can make another $32 million.

It’s about whether Marvel can make enough money to stay ahead of Avatar after both movies have opportunities to increase their totals.

The Final Verdict

For now, Avatar remains the highest-grossing movie of all time worldwide, with approximately $2.924 billion.

But Avengers: Endgame is closer than ever.

After its 2026 re-release, Marvel’s blockbuster has reached approximately $2.892 billion, leaving it only around $32 million behind.

That means the box-office crown is no longer a distant possibility.

It’s within reach.

Whether Endgame actually takes it back will depend on future theatrical releases and how much additional money either movie can generate.

One thing is certain:

The battle between Marvel and Avatar isn’t over yet.
