James Cameron shares details of Kate Winslet’s ‘Avatar 2’ role

She plays one of the Sea People

James Cameron has shared the first details of Kate Winslet’s role in the upcoming Avatar movie sequels.

Back in October it was revealed that the director and actress would be teaming up for the first time since Titanic, for the $1 billion sequels to Cameron’s Avatar franchise.

Now, in a new interview with Vanity Fair, Cameron has opened up on the role Winslet’s character will play in the series.

“She [has a key role], and she’s very excited about it,” the filmmaker says. “She blazed through for a couple of days of rehearsals and saw the world that we had created, and how we do the work, and she’s very excited.

“She plays a character who’s part of the Sea People, the reef people. The one thing she did do is demand that she do all her own water work. I said, ‘Alright, that’s fine, we’ll have to teach you how to free dive’.”

Winslet’s not the only one who’s learning to free dive either, with many of the film’s shots requiring long stints underwater due to the film’s ocean-based setting.

“The other actors are up to three- and four-minute breath holds,” Cameron continues. “We’ve already been doing underwater capture. We did a scene last week with six teenagers, well, actually five teenagers and one 7-year-old underwater holding their breath for a couple minutes and acting, actually doing a dialogue scene under water because they speak kind of a sign language.”

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.”
