Gorillas: From the Heart of Darkness (1970)

Rwanda was once a country of peace, beauty and fabulous wildlife. Romain Baertsoen arrived there in 1966 and started to film two of Rwanda's secrets, the Bahima tribe and rare mountain gorillas. The Rwandan Civil War shattered the peace in 1994, as warring factions pillaged towns and plundered the forests. Remarkably, the gorillas survived, but the world around them is increasingly uncertain.
