James Cameron needs millions of liters of water to film Avatar 2

Director James Cameron said it really took millions of liters of water for the process of shooting the film Avatar 2. At least he needed 3.4 million liters of water to make the film more realistic.

As we know, James Cameron is not a director of 'nuts'. He even refuses to use existing technology to make a film, such as the making of this Avatar 2 film.

In fact, for taking pictures in the water, it is possible to use motion capture technology outside the water and the players will be hung floating so that they look like they are in the water. But it was rejected outright by the director.

"I told my team it wasn't going to look real," James Cameron said in an interview with Entertainment Weekly.

Previously the team had advised James to use the dry for wet technique as described above. But the Titanic director refused because it would eliminate the real essence as he thought.

In order to 'silence' the team, he also tried to take pictures outside the water and compare the pictures taken in the water. And sure enough, it was very different and 'successfully silenced' the team not to suggest what was not on his mind.

"I let them do a test, we recorded images using the dry for wet technique (the players were hung to make it look like they were floating) then we also recorded images in the water. The results were not close at all (to each other)," he said.

Furthermore, the shooting of this film was carried out in a place containing 3.4 million liters of water or the equivalent of 900 thousand gallons. Although the number looks large, it is not much more than Titanic which requires 17 million gallons of water or tens of millions of liters of water.
