While Kate Winslet left the "Avatar: The Way of
Water" cast and crew stunned by holding her breath
underwater for seven minutes while filming the new
blockbuster sequel, Zoe Saldaņa was certainly no
rookie. James Cameron had his cast train with "the
world's best breath-hold specialists" so that he could
film extended long takes underwater. Winslet held her
breath for seven minutes, while Sigourney Weaver got
up to six-and-a-half minutes. Saldaņa's longest underwater
breath hold clocked in at five minutes.
Weaver said she surprised her teacher by holding
her breath for so long, adding, "He said to get rid of
your mammalian instinct to go, 'Oh my God, my face
is in the water.' So, you spend several minutes just putting
your body back into that element and letting those
land-person feelings dissolve."
Cameron said, "Kate's a demon for prep, so she
latched onto the free diving as something that she
could build her character around," Cameron told The
Times, "Kate's character is someone who grew up underwater
as an ocean-adapted Na'vi - they're so physically
different from the forest Na'vi that we'd almost classify
them as a subspecies. So, she had to be utterly calm
underwater, and it turned out she was a natural."
Cameron shot most of "Avatar: The Way of Water" in
large water tanks so that his underwater scenes would
not feel fake. "You want it to look like the people are
underwater, so they need to be underwater," Cameron
said. "Sigourney and Zoe and the others weren't particularly
ocean-oriented folks. So, I was very specific about
what would be required, and we got the world's best
breath-hold specialists to talk them through it."
