The Oscar-winning director has stated that the future of Avatar depends on the third movie, Avatar: Fire and Ash, being a financial success but even if it is axed, he has vowed to bring closure to the fans.
James told Entertainment Weekly: "I don't know if the saga goes beyond this point. I hope it does. But, you know, we prove that business case every time we go out… If we don't get to make 4 and 5, for whatever reason, I'll hold a press conference and I'll tell you what we were gonna do. How's that?"
Disney has Avatar 4 on its calendar for 2029, with Avatar 5 set for release in 2031.
Cameron, 71, would also love to turn the stories into novels but claims that will not be viable as "people aren't reading" anymore.
He said: "There's so much culture and backstory and lateral detail in these characters that's been worked out. I'd love to do something that's at that level of granular detail.
"There's no business model for it anymore. People aren't reading.
"But anyway, it might be good to have the canonical record of what it was all supposed to be."
Avatar: Fire and Ash continues the story of the Sully family, led by Jake (Sam Worthington) and Neytiri (Zoe Saldaña).
The film also features Sigourney Weaver as Kiri, Britain Dalton as Lo'ak, Trinity Jo-Li Bliss as Tuk, and Jack Champion as Spider, along with Stephen Lang as Quaritch, Kate Winslet as Ronal, Cliff Curtis as Tonowari and Bailey Bass as Tsireya.
