Directed by: Luis Llosa
Starring: Jon Voight, Jennifer Lopez, Ice Cube, Eric Stoltz
Other mistake: After they blow up the dam blocking their passage, there is a far away shot as they are going up river and there's a grassy landmass that goes across the river blocking their route up river.
Other mistake: When the anaconda is behind the boat she shoots at it about 5 times with a bolt-action rifle, with no magazine, and never reloads.
Factual error: During the first battle with an Anaconda, the 55-gallon fuel drums lashed to the deck of the riverboat are swept over the side, where they sink to the bottom of the river. This plot device drives the rest of the movie, since the boat must make a dangerous detour through "Anaconda country." There is just one small problem with this: Fuel drums full of diesel fuel or gasoline float on water. The fuel in them makes them buoyant. It would have been a simple matter for someone to get a rope or a boathook and retrieve the fuel drums before they floated away.
Warren Westridge: Asshole in one.
Trivia: The original theatrical trailer for this movie includes the scene where Gary (Owen Wilson) is grabbed from behind by the snake and pulled backwards but the CGI snake hadn't been added in yet so you just see Gary falling backwards. This trailer is available on YouTube.
Question: Okay, so I can't figure out why Paul and Matteo had the whole elaborate ruse set up. Why not just come out by themselves? Why did they set up a stranded boat and take the crew hostage with all of the events in the movie?
Answer: They didn't set it up. They were chasing after the anaconda anyway and were stranded. They still wanted to go after the anaconda after they were picked up, so they lied to the crew. They knew the crew wouldn't go after the anaconda on their own.
