My Octopus Teacher, a documentary about filmmaker Craig Foster as he meets an octopus in South Africa and actually forms a friendship with her, hits Netflix on Sept. 7. Year after year, he dives in the same kelp forest, following along with the same octopus as she grows and changes, and she ends up teaching him lessons he needed to learn about himself. The whole thing looks pretty wild (especially for fans of nature and animals alike), but what about Foster’s life outside of the water?
