Kate Winslet is playing a "water person" in 'Avatar 2'

Straight from the sets, producer Jon Landau posted an image on Instagram showing Winslet dressed in a weird skin-tight costume, flapping huge wing-like structures, in a possibly swimming routine.

He shared this stunning underwater scene that also had two other crew members armed with oxygen cylinders and related equipment.

The team has shot most of their underwater action scenes in New Zealand.

Landau wrote in his caption that he has posted this image following Winslet's interview in The Hollywood Reporter.

Comically enough, he quoted Winslet from her THR interview, since she gave him nothing extra to add to her stunt experiences.

In the interview, Winslet had said, "I had to learn how to free-dive to play that role in Avatar, and that was just incredible."

"My longest breath-hold was seven minutes and 14 seconds, like crazy, crazy stuff," the Titanic star had revealed in that interview.

Without divulging anything further, she stopped right there and added, "Oh no, actually, I can't. Yeah, I play a water person. I am a water person."

Reportedly, she had filmed her portions in 2018.

Avatar 2 marks her second venture with Cameron.

Winslet plays a character named Ronal in Avatar 2 and 3, and this is her first filming experience with motion capture technology.

Previously, the social media handles of Avatar created a lot of noise with lead actor Sigourney Weaver's breathtaking underwater stunt sequence.

Meanwhile, teasers of this much-awaited venture hint that a huge chunk will take place in the oceans of Pandora.
