James Cameron has revealed Avatar 2 will be filmed predominantly underwater.
The sequel, which is due for release in 2020, features a new motion capture system which is proving to be a headache for the Terminator and Titanic film director.
“It’s never been done before and it’s very tricky because our motion capture system, like most motion capture systems, is what they call optical base, meaning that it uses markers that are photographed with hundreds of cameras,” he told Collider.
“The problem with water is not the underwater part, but the interface between the air and the water, which forms a moving mirror. That moving mirror reflects all the dots and markers, and it creates a bunch of false markers.
He added: “We’ve thrown a lot of horsepower, innovation, imagination and new technology at the problem…it’s taken us about a year and a half now to work out how we’re going to do it.”
