New York, New York - Avatar: The Way of Water director James Cameron has given fans a surprising new update on the upcoming sequels.

Speaking with Entertainment Weekly, the 68-year-old filmmaker confirmed that portions of the third and fourth Avatar films have already been shot, though The Way of Water just hit theaters last week.

"Each movie is going to introduce audiences to new clans, new cultures on Pandora," Cameron said.

The director also made a rather bizarre comparison while explaining the logic behind such a quick filming schedule, telling EW he wanted to avoid what he calls the "Stranger Things effect."

Cameron explained further that he wanted to avoid the younger actors introduced in the sequel looking too old in later installments.

Trinity Jo-Li Bliss, who plays Tuk in the Avatar sequel, is 13, while Jack Champion, who plays Spider, is 18. Cameron was worried that these young stars were growing too quickly for a typical production schedule, so he ensured filming happened as fast as possible to keep things realistic.

"Otherwise, you get – and I love Stranger Things –s but you get the Stranger Things effect where they're supposed to still be in high school [but] they look like they're 27," he said.

Cameron's comments struck fans as rather bizarre, especially considering the oldest member of the Stranger Things core ensemble is only 21. The sci-fi hit is even a rarity in this regard, with most shows about teenagers casting actors in their mid-to-late 20s for those same roles.

Many fans also argued that seeing the cast grow up with their characters has made the show even more meaningful.

"This is so annoying they’re not supposed to be kids anymore. They’re teenagers in high school. Kids grow up! Sorry they weren’t 30 year olds like all the other 'teens' on film and the 'stranger things effect'??? It’s the Harry Potter effect. We get to watch them grow up," one Twitter user wrote in response to Cameron's odd comparison.

Not for nothing, a concern for how realistic the actors' appearances are in a film that primarily features them in CGI-made Avatar forms feels pretty unnecessary.
