I first heard about Mokele-Mbembe while I was working with the Pygmee people in the Central Africa republic in 2014. In 2016, I went on two expeditions to search for Mokele-Mbembe in the little-known Nki area, at the border between Cameroon and the Congo, with the famous French explorer Michel Ballot, a former lawyer who dropped everything 15 years ago to try to prove the beast's existence. It was during the second expedition - the most ambitious one, both in terms of budget and of people involved - that I shot my film. And that we found some very interesting evidence of the possible presence of Mokele-Mbembe in the area."
