This is another made-for-TV monster snake movie. One of those where you end up cheering for the monster because it is killing a bunch of evil greedy people. But both of the movie's titles are misleading - there is no snake king or snake man. One of the publicity posters shows a man's head with giant fangs and big scales with the tagline "A New Breed of Predator" but that's a complete lie. There's no such monster in the movie.
The gigantic killer monster snake in this movie has 7 heads with large horns and it roars. It kills people in a few ways - mostly by biting onto their heads or limbs then picking them straight up off the ground and popping them into its mouth. Sometimes the different heads seem to fight over the human snack, each grabbing a part and tearing it off. We also see the giant snake use its tail to coil around a man then crush him into a puddle of blood. And it spits poison at another guy, who dies after his face burns and melts.
There's even a real snake in the movie - one that wasn't made on a computer screen. We see an Anaconda lying on the ground as some men are hiking through the jungle. One of the Baldwin brothers almost steps on it, so the snake bites him on the leg. He grimaces in pain, so obviously in the world of the movie, the non-venomous Anaconda is venomous. Then he aims his rifle and blows its head off. Back at camp, tending to the sick Baldwin brother, the blonde complains that she can't find any "anti-snake venom," whatever that is. Maybe it's like bug spray for snakes?
The giant snake is called Naga and it's worshiped by an Amazonian tribe called the Snake People. Their leader has a chest tattoo of the 7-headed beast. The tribe and the snake guard a fountain of youth in a cave in the Amazon jungle. After finding a coffin with a dead 300-year-old man in it, a giant pharmaceutical company sends a team of people to find out why he lived so long, hoping to find the secret for eternal youth, then bottle it and sell it. (I'll take a bottle, please.) That search leads them to the tribe and the big snake. Those people the tribe don't kill, become food for the giant snake. Except for the large-breasted blonde. The snake likes her. Apparently, giant monster snakes have a thing for pneumatic blondes along with most movie monsters and aliens, as we learned from King Kong and all those 1950's space invasion movies.
The movie decides to shoehorn a love story into the plot at the very end. For the ladies. The snake seems to enjoy watching when the two survivors start smooching next to the fountain, proving that even gigantic 7-headed bloodthirsty monster snakes like a happy ending.
