Marvel Studios

After close to a decade of untouchable box office dominance, "Avatar" has finally given up its crown as the biggest box office earner of all time. And now, its director is heaping praise on the film's successor.

After a re-release that helped it squeak past "Avatar"'s previous world record of $2.789 billion, "Avengers: Endgame" officially became the biggest movie ever over the weekend, earning a staggering $2.791 billion. As he did with other records of his that "Endgame" had previously broken, "Avatar" mastermind James Cameron acknowledged the feat in a social media post.

Addressing the folks at Marvel Studios with a Na'vi greeting, Cameron shared an image of Iron Man covered in wood sprites from Pandora.

"I see you Marvel," the director wrote. "Congratulations to Avengers Endgame on becoming the new box-office king."

"Endgame" directors Joe Russo and Anthony Russo took to Instagram to praise Cameron right back, sharing several images of themselves in silhouette, marveling over Cameron's previous films.

Addressing Cameron directly, the Russo brothers called him "a monumental reason why we fell in love with film in the first place," and thanked the filmmaker for "inspiring us and opening the world’s eyes to what’s possible." The duo closed out their message by saying, "We can’t wait to see where you take us next..."

That would be back to Pandora, with Cameron currently working on four planned "Avatar" sequels, which have been in various stages of development -- but finally seem to be moving along -- for ages. If all goes according to plan, the first follow-up will hit theaters at the end of 2021.

With so much additional content to come from both Marvel and Cameron, we have a feeling that the filmmakers may be trading records for the foreseeable future.
