LOS ANGELES — Walt Disney Co. and filmmaker James Cameron have been sued in a lawsuit filed Monday in federal court by 3D animator Eric Ryder, who claims the “Avatar” franchise copied elements from his unpublished science fiction story and is seeking at least $500 million and an order blocking the planned Dec. 19 release of “Avatar: Fire and Ash.” Ryder says he collaborated with Cameron’s Lightstorm Entertainment in the late 1990s to develop a movie based on his story “KRZ,” and that new acts of alleged copying first appeared in 2022’s “Avatar: The Way of Water,” Dec. 16, 2025.
The case, filed in the U.S. District Court for the Central District of California as Ryder v. Cameron (No. 2:25-cv-11854), names Cameron and Disney and seeks both monetary damages and emergency injunctive relief ahead of the next film’s rollout, according to a Reuters report.
Avatar lawsuit: Ryder claims ‘KRZ’ was copied into the franchise
In the complaint, Ryder alleges that the “Avatar” series contains protectable elements he developed for “KRZ,” including “anthropomorphic beings,” an expansive ocean setting and what he describes as a “sinister, Earth-based corporation” carrying out environmentally harmful mining operations on Europa, a moon of a gas giant planet. The suit also highlights a plot device in “The Way of Water” involving the harvesting of an animal-based substance that can extend human life once refined—an element Ryder claims was part of “KRZ” but not featured in the first “Avatar” film.
Ryder’s filing argues the new case is not a do-over of earlier litigation over the 2009 film. Instead, it claims “new acts of copying” occurred for the first time in “Avatar 2” and may continue into subsequent installments.
What Ryder wants: $500 million, plus a bid to stop “Fire and Ash”
The lawsuit seeks compensatory damages exceeding $500 million, punitive damages and an injunction barring further exploitation of “The Way of Water” and future “Avatar” installments—including “Fire and Ash,” according to a statement released by Ryder’s attorneys at Kasowitz LLP.
In that statement, attorney Daniel A. Saunders described the alleged infringement as “blatant and egregious” and said it “cries out for compensation.” Disney and Lightstorm did not immediately respond to requests for comment, Reuters reported.
Why timing matters with the Dec. 19, 2025 release date
Ryder’s request to block the next movie puts added pressure on the court calendar with the film scheduled to open Friday, Dec. 19. The release date is listed on 20th Century Studios’ official film page and in a Disney Studios UK press release that promoted a trailer and film stills ahead of the worldwide theatrical debut.
Even if a case ultimately turns on complex questions of access, substantial similarity and what parts of a story are protectable expression versus unprotectable ideas, Ryder’s immediate ask is narrower: a court order that could disrupt a major studio release just days before it opens.
A longer timeline: earlier Ryder claims and past rulings
The new suit arrives after years of prior legal sparring tied to Ryder’s “KRZ” allegations. Past coverage shows his earlier claims did not prevail in court, a history that now forms part of the backdrop for his renewed effort targeting “The Way of Water” and “Fire and Ash.”
In 2011, Ryder’s dispute over the original “Avatar” drew public attention, including a Guardian report describing his allegation that he developed an eco-themed project for Lightstorm before the blockbuster hit theaters.
In 2013, the Los Angeles Times reported that a judge granted summary judgment for Cameron, finding the film was independently created.
In 2016, Courthouse News Service reported on an appellate decision concluding the creators did not lift elements from Ryder’s short story and that “Avatar” was independently created.
Ryder’s latest filing attempts to clear a different hurdle by focusing on what it calls fresh, post-2009 copying—specifically in the 2022 sequel and, potentially, the 2025 installment. Whether that distinction is enough to revive the dispute, and whether any request to block “Fire and Ash” gains traction, will be decided in federal court.
