“Last Breath” continues an ongoing trend of fictionalized remakes of the events covered in a prior documentary. This movie uses the 2019 documentary of the same name as its basis. Both films were directed by Alex Parkinson, who uses real-life footage of the people involved during the closing credits of this fictionalized version.

Perhaps it makes sense that Alex Parkinson's feature debut would simply be a flip of the dimensions of his usual fare. The documentarian has long made a career out of the kind of nature documentary that is more about the people said nature affects than the nature itself.

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.

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."

"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.

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.
