No sequel had bigger shoes to fill than 'Avatar: The Way of the Water.' The 2009 original was a cultural phenomenon. It beat the record as the highest-grossing film of all time. It influenced an entire industry to begin producing 3D televisions and mobile devices, and it changed the way movies were made.
It was filmed using technology created by director James Cameron. He also helped to develop the Na'vi language, their culture, and a virtual, alien ecosystem based on models of our own rainforest.
The Way of the Water promised to be just as ambitious as its predecessor. It had one of the highest production costs of any film ever made, topping out at over $460 million. Cameron spent the better part of a decade developing more technology, new filming techniques, and equipment. He promised all new ocean ecosystems. He even dove to the bottom of the Mariana Trench, vowing to bring back footage for the sequel.
