Takes place in the Amazon basin, but shot in Southern Mexico
I like the movie -- it's not great, but I like it -- however, I noticed they shot the film in the area of Catemaco, Veracruz, Mexico, not far from the southern Gulf of Mexico. I'm sure the producers chose this location because it was much cheaper to shoot there (being fairly close to civilization) and also because of the scenic mountains.
Still, it's supposed to be a film about the Amazon rain forest, not the Southern Gulf Coast region. Oh well; it looks good anyway.
