Avatar originally earned an enormous $ 2.789 billion when it was first released, replacing Titanic.
This week’s re-release of Avatar in China has pushed the film back to the top of the leaderboard, however, with a new highest-grossing movie score of $ 2.798 billion.
Avengers Endgame has now been placed as the second highest-grossing movie of all time.

Avatar was extremely popular when it was originally released partly thanks to the use of state-of-the-art RealD 3D technology.
For the first time viewers witnessed the ethereal alien world of Pandora in 3D and were introduced to the Na’vi – the inhabitants of the planet.
Sam Worthington played disabled former marine Jake Sully, who was implanted into a Na’vi avatar to gather information and learn from the species.
Last year 20th Century Fox was bought up by Disney, who also own Marvel.
In September Cameron revealed Avatar 2 is “100 percent” filmed and he has almost finished filming Avatar 3.
He said at the time: “Now, that doesn’t mean that I have an extra year to finish the film because the day we deliver Avatar 2 we’ll just start working on finishing Avatar 3.
“So where we are right now, I’m down in New Zealand shooting. We’re shooting the remainder of the live action.”
At the moment, Avatar 2 is due to be released on December 16, 2022.
Avatar 3 is currently slated for release on December 20, 2024.
Both sequels will include the return of Avatar’s actors, including Worthington, Saldana, Stephen Lang and Sigourney Weaver.
Avatar and Avengers Endgame are both available to watch on Disney Plus now.
