Filming began only in 2017 (before that, the script was being slowly developed). Five years for such a large-scale canvas is not such a long time. In addition, there was a stop for more than four months due to the pandemic. But over the years, the third part of the film has also been completely filmed, and even the shooting of the fourth has begun. Later, the start of the production process, as in the case of the first "Avatar", is explained by the desire to wait for the release of technologies to a higher level.
