Sam Worthington has given an update on the next instalment of Avatar.

Speaking to People magazine, Worthington, who plays Jake Sully in the franchise, says the cast of the James Cameron-helmed films are gearing up to return to production in February.

“We go back to work on it in a month and it’s big. It’s bigger than you can imagine,” he said.

Worthington didn’t share specifics, but according to Variety, it’s likely that he and the cast might be returning to Cameron’s studio next month for Avatar 3 post-production work.

In December, Cameron confirmed that Avatar 3 “is right on track” for a Christmas 2025 release, after it was originally set to be released in December 2024.

Elsewhere in the interview, Cameron spoke about the process of making the third Avatar movie.

“Three is actually much more straightforward than two,” Cameron told People about the post-production process.

“Two, we got hit with the pandemic in the middle of it and we were interrupted, and then we had to reboot and reboot the production and all that sort of thing. And it was a scramble to get it done.”

Cameron also told Deadline that the next Avatar film will use fire as “a symbolic purpose in the film and there’s a culture that is specifically around that concept.”

He also confirmed that Kate Winslet will return to reprise her role as Ronal. Adding that Winslet “went to school” learning from “a husband and wife shaman practice” to master techniques she will employ in the next film.

In an interview last year with GQ magazine, Cameron said expanding the Avatar story over numerous films allowed him to focus on character as well as spectacle.

“The big [creative] advance in [Avatar 3] is just going to be greater character depth,” Cameron said.

“We’re seeing new cultures, new creatures — all the same stuff you’d expect from an Avatar movie, but the whole idea of this cycle of films is to live with these people and go on this epic journey with them.

“So I think it’s not about, ‘We’re going to show you the best water [VFX] ever done’ — but you get more into the heart and soul of the characters. And there’s some very interesting new characters that come in as well.

“This is a journey over time. It will play out through movie three, into movie four and movie five. There’s an epic cycle to the whole thing.”
