Revealing mistake: When Bill sets the tribe's hut on fire, everything lights up instantly and within moments the whole thing is alight, although it takes longer than that for a whole hut that size to set in flames.
Factual error: Crocodiles do not hunt by smelling blood like sharks do. They have keen eyesight and would also be attracted by the splashing water.
Cole Burris: I had this friend, who had this friend who shot documentaries, and he and his whole crew went down to the Amazon, and they were all eaten by snakes, and that's a true story.
Gordon Mitchell: Come on Cole, you knew a guy who knew a guy. That's an urban myth.
Trivia: The Chinese tattoo on Bill's arm reads Wo de shi jie, which means "My world."
Question: Does the movie provide any evidence that the Blood orchid flowers would renew human youth like a fountain of youth?
Answer: No, it doesn't. The characters speculate that the anacondas are unusually large because the orchids are part of the food chain in the area; then have a discussion over whether or not the orchids would have the same effect on humans. This discussion is unresolved and the question goes unanswered for the rest of the film.
