Congo is a fun but absurd jungle adventure action movie from a Michael Crichton novel. There's an evil corporate megalomaniac and the an ex-C.I.A. woman scientist he sends to Africa to find out why an diamond-hunting expedition team was killed. There's a treasure hunter looking for a lost city of diamonds. There are soldiers attacking any foreigners during a military coup. And there's a gorilla that can talk using sign language and an artificial voice that is being returning to the wild from UC Berkeley. The movie throws in everything but the kitchen sink to add as much tension and conflict as possible. It's not enough that a group of people is flying to an active volcano in a distant African jungle where monster gorillas rip off people's heads, when they land in Zaire from America they first have to hide out to escape a military coup then their next plane is shot at forcing them to parachute into the forest, where horrible, deadly, monstrous creatures constantly threaten their lives. You got it, I'm talking about snakes. It's the law - you can't make a jungle adventure movie without showing that the jungle is full of deadly snakes, and this one is law-abiding. One night when they are camped in the dark rain-drenched jungle, a guard spots a snake on a branch next to him so he draws his knife and hacks off its head. I guess he was to lazy to move.
We see a live snake, but I don't know what kind it is. Some of the movie was filmed in Africa, and some in Costa Rica, so it could be from either continent. The snake we see missing its head seems to have a different banded pattern than the live snake, so it might be a fake.
