IMDB’s description:
A biology teacher [trying] to save his ill daughter with a natural cure goes into the jungle with experts and finds a horror that’s larger than life
This movie opens during World War 2. A platoon of Japanese soldiers are exploring a jungle. Suddenly one of them comes flying out of the tree line. A giant snake (like something out of Harry Potter) emerges and commences to kill the platoon.
Where Steven Spielberg learned less is more in Jaws and Jurassic Park when it comes to revealing the monsters. This movie goes the other route, revealing the big monster less than 1 minute into the film (a film that is only 79 total minutes in length).
