Avatar producer Jon Landau has revealed that filming on the first part of the fourth film has already been completed.
Four sequels to the blockbuster 2009 sci-fi movie are in production and will be released at the rate of one of every two years, starting this December with the second film in the franchise - Avatar: The Way Of Water.
Filming on the second and third movies took place simultaneously between 2017 and 2020, while filming on the final two began last month, although Landau has revealed that the first act of Avatar 4 was actually shot several years ago.
"We've completed most of the first act of Avatar 4 and there were logistical reasons why we needed to do that," Landau told Variety.
"We've designed most of the whole movie for Avatar 4 but we haven't actually filmed all of it – just the first act."
Avatar: The Way of Water is due for release on December 16.
