Trivia, insights & behind the scenes
Christian Clot has run multiple 'Deep Time' missions; this was the first all-female cave expedition, though the film focuses on mixed groups.
The crew couldn't enter without breaking the experiment—everything was captured via fixed cameras and the subjects' own recordings, creating an accidental found-footage aesthetic.
