In September 2012, the young Mr. Lemons was trying to repair some pipeline along the floor of the North Sea when disaster struck on the surface 300 feet above, ultimately severing the “umbilical cord” that connected the diver to his ship and stranded him in the pitch-black deep with only seven minutes’ worth of oxygen in his reserve tank.

"Last Breath" delivers every incident with such specificity that it's like a cinematic piece of journalism. Yet it leaves you with a minor tingle of the uncanny.

A routine deep sea diving mission in the North Sea goes terribly wrong when a young diver is stranded some 300 feet below the surface in the new film “Last Breath.”

Alex Parkinson's true-life adventure thriller, based on his 2019 documentary, recounts the efforts to rescue a saturation diver trapped hundreds of feet below the water's surface.

Woody Harrelson ( Zombieland) portrays Allcock while Simu Liu ( Shang-Chi and the Legend of the Ten Rings) and Finn Cole ( Peaky Blinders) tackle Yuasa and Lemons, respectively. Cliff Curtis ( Avatar: The Way of Water) and Mark Bonnar ( Napoleon) co-star.
