Trivia, insights & behind the scenes
Laurent Ballesta's 2019 'Gombessa 5' mission required inventing entirely new decompression algorithms—no human had attempted saturation diving for that duration before.
The film's French title 'Dans les abysses' deliberately echoes Cousteau's 1956 'Le Monde du silence,' positioning Ballesta as the spiritual heir France has been waiting for since Cousteau's death in 1997.
