Reported that writers are considering making this fourth installment a prequel to the first Avatar (2009) film
When James Cameron showed the script for this film to Fox Executives their only note back was "Holy f-ck".
According to James Cameron, the Avatar sequels were such a massive undertaking that Cameron divided the three scripts between the writing team of Rick Jaffa, Amanda Silver, Josh Friedman and Shane Salerno. Cameron delves further explaining the story process: "I think we met for seven months and we white boarded out every scene in every film together, and I didn't assign each writer which film they were going to work on until the last day. I knew if I assigned them their scripts ahead of time, they'd tune out every time we were talking about the other movie."
The entire crew received an exclusively vegan diet during filming. With this step, James Cameron and the producers wanted to amplify the environmental message of the film.
