Mount Elgon is an extinct volcano on the border between Uganda and Kenya. Director Harald Pokieser and his camera team spent several weeks filming here in challenging conditions. As Pokieser explains, “We thought that filming the gorillas in Bwindi would be the most difficult part of the film. We were wrong. Filming the elephants on this densely overgrown mountain was far more challenging. You sweat constantly while climbing up and down, and at night you freeze in your tent.” Without a doubt, the team’s exertions were worth it. In fact, using automatic 4K cameras, they were even able to capture female elephants and their calves entering caves at night in order to lick the salt from the cave walls. Filming also took place in other parts of Uganda.
