Snakeman (2005)

Anthropologists deep in the Amazon uncover the remains of a man they come to determine was approximately 300-years old when he died. This leads to a second expedition to discover the reason behind his longevity, but there's a major problem in the form of an Amazonian tribe that guards the proverbial fountain of youth and the giant, five-headed snake they worship.

Snakeman is an adventure movie featuring Stephen Baldwin and directed by Allan A. Goldstein.
