The search for their father...
led them to HELL!
This is a low-budget jungle adventure/animals run amok horror movie. The poster promises a giant monster snake, so that's why I watched it, but you don't have to.
Amanda and her brother Scott travel to the Amazon to find their missing father along with Vera, who works for the logging company their father works for. They hire some guides who take them on a boat upriver into the jungle where they are attacked again and again by jungle animals - killer caiman, piranha so vicious they eat the entire boat, poison dart frogs (you can see the frog scene here), giant spiders, and of course gigantic snakes. Even the jungle plants attack them. It's all because the logging company that is destroying the jungle found an ancient artifact of a very angry god named the Curipira that protects the Amazon causing him to come to life. Or something like that. The plot is a confusing mess. We finally see the giant flaming Curipira at the very end but by that time I had lost all interest in trying to figure out what it meant.
The main snake scene
Before they get off the boat their guide warns them that the Amazon is a dangerous place, with Anacondas that can swallow you whole. That sets us up for the scene with the giant snakes, but we have to wait an hour to see them. (Feel free to skip ahead.) We see one giant snake in the jungle near their father's trailer, but it does nothing. Eventually the group enters a cave under a waterfall where some giant Anacondas hang out, surrounded by human skeletons. One by one the giant snakes swallow them in a ridiculous way - the actors all stand still and straight and then the snakes come down from above with their mouths open and swallow them by the head. No snake feeds that way, especially not Anacondas, which wrap around their prey and squeeze the air out of them. Even the protagonist Amanda gets swallowed, but in a nice twist, which I found the most interesting thing about the movie, we see that she was smart enough to grab a machete before she was swallowed which lets her cut through the snake from the inside to free herself. That wouldn not work if the Anaconda had constricted her first. She crawls out all covered with snake goo and yells at the other snakes. Then she cuts off the head of one of the snakes and cuts it open to free her brother and Vera.
The snakes are very bad CGI, as are all of the other jungle creatures except for a couple of real poison dart frogs. Even the snakes behavior is disappointing. They hardly put up any kind of fight against Amanda. As I already said, the way they ate the humans was ridiculous, but it's very common in giant monster snake movies since it's much easier for the animators.
