‘Avatar’ director James Cameron says generative AI is a threat to real acting

Filmmaker James Cameron has expressed deep concern over the rapid rise of generative artificial intelligence in Hollywood, calling the notion that AI can create an actor and a full performance from a simple text prompt “horrifying. The director of Avatar and Terminator stressed that storytelling must remain grounded in human performances, not algorithm-generated substitutes.

Cameron recalled that even during the early development of the first Avatar film in 2005, some in the industry believed he was working toward replacing human performers with computer-generated characters. He rejected those assumptions then and reaffirmed now that his creative process is built entirely around actors and their emotional presence. He explained that the performance-capture technology used in his films merely extends what an actor can do rather than eliminates the actor’s role. “For years, there was this sense that, ‘Oh, they're doing something strange with computers and they're replacing actors,’ when in fact, once you really drill down and you see what we're doing, it's a celebration of the actor-director moment,” he said.

According to Cameron, the challenge emerging today is fundamentally different. Generative AI, he warned, has the ability to construct characters, actors and entire performances from scratch, without any human input. “Now, go to the other end of the spectrum, and you've got generative AI, where they can make up a character. They can make up an actor. They can make up a performance from scratch with a text prompt. It's like, no. That's horrifying to me. That's the opposite. That's exactly what we're not doing,” he said.

His remarks come months after the AI-generated performer Tilly Norwood was unveiled at the Zurich Summit by comedian and producer Eline Van der Velden. The virtual actor sparked widespread criticism from filmmakers, guilds and industry bodies worried about creative authenticity and the future job security of performers.

Van der Velden, however, insisted that AI will continue to grow within filmmaking. She predicted a gradual integration throughout the industry, with AI soon contributing to effects work, establishing shots and second-unit sequences before eventually paving the way for fully AI-generated films. She added that audiences may not even notice when they are watching an AI-created production. According to her, the success of such films will rely on storytelling rather than the method used to produce the visuals.
