Sharing a picture from the set of the movie on Instagram, Landau said the sets were ready and the team behind the film was excited to head back.
Cameron, recently, opened up about the impact of the pandemic on the sequels, saying: "It's putting a major crimp in our stride here".
Landau also pointed out some of the special bits of kit that fans can expect to see in the film when it comes out.
The sea vessels look massive and intimidating, and will likely be the ships used by the humans to traverse the mostly water-covered world that Avatar 2 will be exploring.
Production on the four Avatar sequels, which were shooting back-to-back in New Zealand, was put on pause in March due to the coronavirus (COVID-19) pandemic, but Cameron and crew have continued chugging on remotely, with the New Zealand-based WETA Digital continuing to work on the movies' visual effects. At the same time, most flights to and from New Zealand were restricted as part of efforts to stop the spread of COVID-19. "We're trying to get back to it as quick as we can".
"So there's a very good chance that our shoot might be delayed a couple of months, but we can still do it".
"But my work is on the stage doing the virtual cameras and so on, so I can do a bit of editing, but it's not great for me". The film is slated to release on December 17, 2021. As of now, the sequel has the release date of December 2021.
