People go up river, big snake is very hungry. Guess what happens.
—The NZ Listener's twelve-word review of Anaconda
Anaconda is a 1997 monster movie with an All-Star Cast ranging from Owen Wilson to Jon Voight to Jennifer Lopez to Ice Cube on the hunt (in their own various ways) for the eponymous giant snake. Largely notable for Jon Voight as Paul Sarone, chewing up scenery with a far greater appetite than any serpent could muster.There were three sequels which oddly enough Arc Welded itself across three movies:
Anacondas: Hunt for the Blood Orchid (2004): Which had a company sending a team into Borneo to find a flower that was supposedly the fountain of youth. Not surprisingly they have to contend with the numerous anacondas to get it.
Anaconda 3: The Offspring (2008): In which one of the anacondas was captured and experimented on to find out its longevity. It escapes, breaks out its mate and goes on a rampage (made more deadly due to the fact that these anacondas have spear tails from the experiments...no we're not making that up) some mercenaries are sent to get it back. Notable for staring David Hassleholf
Anacondas: Trail of Blood (2009): Which continues where 3 left off. The offspring of the previous anaconda is found and used to help make the flower. The anaconda breaks out once again while the employer from the last movie sends more mercenaries after the scientist who took the anaconda for his own to get the fountain of youth serum. All the while a previous character from the last movie is looking to destroy it. Yeah its just as confusing and convoluted as it sounds. Oh the snake can regenerate in this one.
The latter two movies were direct-to-video, and all three sequels are considered worse than the original. A fourth sequel which will also be a crossover with Lake Placid will be released in 2014.
They don't eat multiple preys the size of a human being one after the other. After consuming a meal like that (which can take hours), the snake will find a secure location where it will remain immobile for months to digest its food.
They certainly don't regurgitate their prey just so they can hunt again out of sheer sadism. They sometimes do this for safety purposes, such as when they're threatened by a predator and they can't afford to be lethargic by having such a big meal in their stomach.
They're constrictors, they don't just grab their prey and swallow it. Even when they find a dead animal, they'll usually constrict it first just to be safe.
Big Bad: Jack is exposed as this by the end of the film.
Black Dude Dies First: Gloriously subverted when the whiny, scared, "we never should have come here" black guy is one of the four people to survive to the end. And all of his complaints were actually valid (and typically considered valid by non Idiot Ball holders), if ignored. The other black guy in the cast does get killed, but he's nowhere near the first.
Super-Persistent Predator: Justified. The movie somewhat succesfully gets around the previous film's problem of having the snake pursue the heroes for so long to eat them by there being many snakes in the same area due to a mating season being in progress.
