Great jungle movie made by Ruggero Deodato in the early 80's. Some very gruesome scenes, especially one where a tortoise/turtle gets killed and ripped apart, had me turning my eyes away and resting them on the girl for a while. The movie basically makes fun of the Mondo "documentaries" that were quite popular back then.
In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.
