4 mois sur ma biosphère

After traveling the globe to highlight low-tech, Corentin de Chatelperron has set himself a new challenge: to live independently, alone for four months, on a bamboo raft floating in Phang Nga Bay, Thailand. On his 70 square meter platform, the engineer, passionate about ecology and system D, puts into practice what he has learned in order to feed himself and produce his own energy.

Directed by Laurent Sardi, Corentin de Chatelperron, 4 mois sur ma biosphère leans on a strong ensemble — Corentin de Chatelperron — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about documentary titles of 2021.
