Kate Winslet has revealed the surreal partner she had to act opposite during an emotional death scene in Avatar: The Way of Water.

As revealed in Disney Plus documentary Fire and Ash – Making the Avatar Films, the moment that sees Kate Winslet's Ronal react furiously to the death of her spirit sister Tulkun Ro'a was actually done with Winslet floating in a tank next to a large metal grate with an eye stuck on it.
