According to China Film CINITY Co, director James Cameron had a CINITY screen installed in his New Zealand studio. In October, Chinese technicians transported the screen and spent 15 days installing it, allowing the director to see his visual effects demonstrated with exceptional vividness. A key technical upgrade involved brightness: the 3D brightness in Cameron's studio was 14 foot-lamberts, while the CINITY system was calibrated to 17.5 foot-lamberts, resulting in brighter and clearer images.

Despite overseeing such cutting-edge technology, Cameron, the legendary director who has helmed three of the world's five highest-grossing films, two of which are the first and second Avatar movies, says that although everyone sees him as a technical person, "the most important technology in filmmaking is still acting."

With more than 3,000 people involved in its production, the latest film was shot concurrently with the second installment, Avatar: The Way of Water, released in 2022.Over 18 months, the cast used performance-capture technology, translating their work into the film's characters: the blue-skinned, 3-meter-tall Na'vi, and their counterparts, the gray-skinned members of the Mangkwan Clan, also known as the Ash People, the new antagonists.
