James Cameron Shot "Avatar 3" and "Avatar 4" Early to Avoid Ageing Issue

Canadian filmmaker James Cameron gave more insight into the Avatar franchise.

The first sequel to 2009's "Avatar" hit theatres last week, and three more Avatar movies are already set to release in 2024, 2026, and 2028, respectively.

As "Avatar: The Way of Water" continues to blow up worldwide, Cameron has disclosed that his game-planning is far into the future.

In an interview, the acclaimed director noted that has shot scenes from a proposed "Avatar 3" and "Avatar 4" concurrently with the recently released sequel.

The move to avoid having the younger cast members age out, bringing up Netflix’s "Stranger Things" as an example of the problem of time marching on.

"Avatar: Way of Water" introduces Tuk (Trinity Jo-Li Bliss and who was 7 years old when cast but is now 13) and Spider (Jack Champion, who was 12 when cast and is now 18).

"Because Champion was 'growing like a weed', the second, third, and first act of the fourth movie had to be done in one production," Cameron told Entertainment Weekly.

“Otherwise, you get – and I love Stranger Things – but you get the Stranger Things effect, where they are supposed to still be in high school [but] they look like they’re 27,” Cameron said. “You know, I love the show. It’s okay, we’ll suspend disbelief. We like the characters. But, you know.”

Producer Jon Landau also revealed in the same article that upcoming movies will feature new biomes.

“Each movie is going to introduce audiences to new clans, new cultures on Pandora,” Landau said.

“Once we introduce a character, they stay a part of the ongoing evolution. We just add to it. So you can expect to see the Metkayina that you meet in this movie in subsequent movies," he added.

"There are other clans that we’ll introduce in movie 3 that you’ll see in movie 4 and so on and so forth.”

"Avatar: The Way of Water" has generated so far $168 million domestically and more than $500 million worldwide.
