Director James Cameron has revealed some details about the highly anticipated "Avatar 2," saying it will partially take place on Earth.

"Just like Dune takes place across worlds, the later Avatars take place across, certainly across two worlds, because some of it takes place on Earth as the story evolves," Cameron told "Dune" director Denis Villeneuve on Thursday.

The 67-year-old director further explained why he chose Earth as one of the locations. He said the different ecosystems helped him create the backstory.

"The desert planet Earth is not one ecosystem. It has desert it has rain forest, it has ocean polar, boreal forest and so on," Cameron explained. "I'm inspired by the Earth. I'm going to a planet that's so rich and so complex that has so many different ecosystems."

Fans took to the comments section to praise the "Avatar" franchise and "Dune."

One of the fans commented, "Avatar changed the game. Avatar 2 will as well. James Cameron is the greatest at sequels. Hopefully, he moves it up to the summer next year!"

Another fan said, "Dune was great, ballsy just to do the first one and hope!"

"Avatar 2" is set 14 years after former human soldier Jake Sully (Sam Worthington) and Na'vi warrior Neytiri (Zoe Saldana) settled down and started their own family.

The first installment was dropped in 2009 and it turned out to be a massive hit. Since then, fans have been waiting for the second installment. The sequel was planned in 2012 and the writers began to work on the story in 2013. The filming started in 2017.

The sequel will star Sam Worthington, Zoe Saldana, Jamie Flatters and Kate Winslet. Sigourney Weaver, who died in the first installment, will play a new character in the upcoming installment.

The sequel will also mark Cameron and Winslet's reunion after working together in "Titanic," which was released in 1997.

"Avatar 2" is slated to release in theaters on Dec. 16 next year. Besides "Avatar 2," the director is also simultaneously working on "Avatar 3," "Avatar 4" and "Avatar 5."
