James Cameron has announced that the main cast of the Avatar sequels have wrapped production. While the main cast is finished with the sequels, Cameron will go through the lengthy post-production process.
Actress Sigourney Weaver revealed last month that she was working on Avatar 4 and Avatar 5, adding that there is a lot of underwater scenes, which meant that she and the other actors had to learn how to free dive to get into their roles.
On the official Avatar Twitter account, Cameron shared a video message where he provided an update on the sequels. He mentioned the team is currently shooting stunt scenes on the performance capture stage, but the main actors are all done. Cameron specifically mentioned Sam Worthington, Zoe Saldana, Sigourney Weaver, Stephen Lang, and Kate Winslet in the clip, praising the work they did on the films.
Though Avatar 2 won't premiere until a couple of years from now, the nature of Pandora and its various inhabitants guarantees the film (and its sequels) will have rather extensive post-production processes. Even by modern tentpole standards, the Avatar franchise is heavily reliant on CGI, which requires a tremendous amount of work in order to look "right." Especially after the original movie raised the bar for moviemaking technology, Cameron isn't going to skimp in this department.
