After Thirteen James Cameron Plans to release the Sequel for the Block buster Avatar in Dec. 2022. The director told Entertainment Weekly that the preparation for the film took many years as actors were preparing  to hold their breath for minutes for all underwater scenes.

Actors, including Sigourney Weaver and Kate Winslet, spent months training with Marines to learn to dive without equipment. According to Cameron, Weaver can now hold her breath for 6.5 minutes, but Winslet takes the cake: the actress can hold her breath for 7.5 minutes.

“We tried to shoot the film above water, but it became clear very quickly that that didn’t work. The movements are not right. It is not comparable,” said Cameron. The director ultimately chose to shoot the film in a water tank with a capacity of 340,000 liters.

“My favorite moment was when Kate walked by underwater. She looked at me, waved and then walked to the other side of the tank. While that thing is about 12 meters wide,” the director marvels at the actress with whom he also worked with for Titanic .

Avatar 2 revolves around the characters of Sam Worthington and Zoe Saldana, who have started a family. In total, Avatar should have four sequels that are now being shot one after the other.
