"Avatar: The Way of Water" explored the depths of the Pandora oceans, but that wasn't the only story people had in mind for the sequel. Screenwriter Rick Jaffa told Entertainment Weekly that a different version would have depicted the Na'vi going outside their planet. "There was one idea of a space battle with Na'vi," Jaffa said.
The writers were enthused but didn't know how to incorporate the fight into the movie. Even the man behind Pandora, James Cameron, took a crack at it. "He went off and he wrote an entire script. And, by the way, a brilliant script," Jaffa said. However, the script didn't make it out of the writers' room. As Jaffa noted, despite the excitement surrounding the potential for a possible epic space battle featuring the Na'vi, "the whole script got thrown out because it just didn't really work with the story we were telling."
Luckily, the material didn't go to waste. Instead, Sherri L. Smith's licensed comic, "Avatar: The High Ground," adapts part of the story, with the multiple-volume books taking place around the same time as the new film.
