‘Horrifying’: James Cameron explains why Avatar rejects AI actors completely

Ahead of the release of Avatar: Fire and Ash, director James Cameron has expressed strong opposition to the use of generative AI for actors, describing it as “horrifying” and producing “an average” of human creativity rather than unique performances.

Speaking to CBS’ Sunday Morning, Cameron contrasted AI-generated performances with motion-capture technology, which he praised as “a celebration of the actor-director moment.”

Cameron criticised AI’s creative limitations, stating that generative models are trained on existing human art and experience, and cannot replicate the idiosyncrasies of individual actors or screenwriters. “What generative AI can’t do is create something new that’s never been seen,” he said. Cameron emphasised that he does not want to replace actors, noting that he loves working with human performers.

The director reiterated this stance in an interview with ComicBook.com, confirming that not a single frame of the upcoming Avatar sequel uses AI, and stressing that the films are built entirely on real human performances, not digital shortcuts. “We honour and celebrate actors. We don’t replace actors,” Cameron said, calling the potential misuse of AI in Hollywood an “existential threat from big AI.”

The cast of Avatar has long emphasised the effort and skill required for their performances. Zoe Saldaña, who plays Neytiri, described performance capture as “the most empowering form of acting,” highlighting that the franchise depends on the actors’ physical and emotional work. The cast trained extensively in archery, martial arts, free diving, scuba, movement, and a constructed language, bringing the characters of Pandora to life.

Cameron has clarified that his concerns are specific to AI actors in the creative process. While he has joined the board of directors of Stability AI and is exploring AI in post-production VFX workflows to reduce costs and increase efficiency, he emphasises that storytelling, acting, and character creation remain human domains. He stated that AI cannot write a screenplay with the depth of human experience, emotion, and nuance required to move audiences.

Cameron and his team continue to champion human-driven filmmaking, ensuring that the Avatar franchise remains a showcase for real actors performing with cutting-edge technology. Avatar: Fire and Ash is scheduled to open in theatres on 19 December 2025 from Disney and 20th Century Studios.
