Jurassic Park is a science fiction-adventure-drama film directed by Steven Spielberg, based upon the novel of the same name, written by Michael Crichton. The story involves scientists visiting an safaria amusement park of genetically engineered dinosaurs on an island over one weekend. Sabotage sets the carnivorous dinosaurs on the loose, and the technicians and visitors attempt to escape the island.

The film began its genesis before the novel was even published, and Crichton was hired to write a script that skimmed down its plot. Spielberg hired Stan Winston Studio' puppets and worked with Industrial Light and Magic to develop cutting edge CGI to portray the dinosaurs. The film stars Sam Neill, Jeff Goldblum, Laura Dern and Richard Attenborough. It reached near-universal acclaim.

It was well received by critics, although they criticized the plotting and characterization. Since its release it has grossed $914,691,118, becoming the highest grossing film of all time, and is currently the eighth-highest grossing feature film. Most significantly, the film inspired a new breed of films that primarily used CGI for special effects.

The film was followed by The Lost World: Jurassic Park on May 23, 1997, Jurassic Park III on July 18, 2001, neither of which were as financially successful or as critically acclaimed as the first, and Jurassic World on June 12, 2015, which was more financially successful, but not as critically acclaimed as the first. The film was re-released in the cinemas of U.K. on September 23, 2011 and in 3D on April 5, 2013.


On the volcanic island of Isla Nublar, an InGen employee is attacked and killed by a Velociraptor, possibly a pack leader known as The Big One, while attempting to transport it to a heavily fortified enclosure. This prompts the worker's family to file a lawsuit against the company, and it successfully scares InGen's investors into thinking that the park is not safe. The CEO of InGen, John Hammond, decides to reassure the investors by bringing a group of experts to his park in order to gain their approval of it. Among the group he invites Paleontologist Dr. Alan Grant and Paleobotanist Dr. Ellie Sattler, two scientists whose digs he's been funding, Ian Malcolm a mathematician (or "Template:W" as he calls himself) and his investor's lawyer, Donald Gennaro. Meanwhile in Costa Rica, Dennis Nedry is meeting with Lewis Dodgson, a rival scientist of InGen working for Biosyn. Dennis is a computer programmer working for John on Isla Nublar and has recently become dissatisfied with his treatment by InGen. Dennis agrees to steal dinosaur embryos for Dodgon for a price.

The group assembled by John arrive on the island via helicopter and then take two jeeps out into the park, where they come across a Brachiosaurus and a whole herd of hadrosaurs, to their utter amazement. John then takes his stunned guests to the Visitor Center, where they see the birth of an infant Velociraptor and learn that InGen were able to recreate dinosaurs using DNA taken from mosquitoes who had feasted on dinosaur blood, and had been preserved in amber. The DNA taken from the mosquitoes was spliced with DNA from frogs to fill in the gaps of the genetic code. InGen scientists only cloned female dinosaurs, thus eliminating the threat of uncontrolled breeding of the animals.

They are then taken to the Velociraptor enclosure at Alan's request where they meet park warden Robert Muldoon. Robert tells the group about how vicious and intelligent the raptors are. He explains there are only three raptors all together because The Big One, who has taken over as the alpha female, had "killed all but two of the others", a total of eight raptors. Meanwhile, the scientists lower a cow into a dinosaur's enclosure and observe it eating the cow, destroying the support cables and fabric harness in the process. After the experiment, the scientists head indoors for lunch.

During the lunch Alan, Ian and Ellie start to express doubt in the park after the initial shock has worn off. Ian questions the ethical morality in cloning species that had not lived for thousands of years. Ellie expresses concern that the scientists may not be thinking of the repercussions that might occur of what they are cloning. Alan remains fairly neutral on the issue though he advises John to be careful. Donald is the only one who completely approves, thanks to the amounts of money they could make off the island. Hammond puts it eloquently "I don't believe it. You're meant to come down here and defend me against these two characters and the only one I have on my side is the blood-sucking lawyer!"

After the lunch, the team will start on a tour through the park. The visitors are toured around in electric Tour Vehicles. John's grandchildren, Lex and Tim Murphy, also take the tour. Both of them instantly take a liking to Alan, who doesn't appreciate the attention as he dislikes children. While on the tour, a goat is released out in the wild close to the fence to attract the dinosaur and eat it, while the visitors observe it. The tour goes disappointingly, with most of the dinosaurs failing to appear. Ellie leaves the tour to take care of a sick Triceratops with the veterinarian Dr. Harding.

A tropical monsoon storm hits the island, and most InGen employees leave, except for John, game warden Robert, and chief systems engineer Ray Arnold. During the storm, Dennis shuts down park security (except for the raptor fences) and as a result, the Tyrannosaurus breaks through the deactivated electric fence surrounding its pen, kills and eats the abandoned goat and devours Donald, attacking Tim and Lex hiding in the car, which gets submerged partway into a swamp of mud and wounding Ian. The children and Alan only narrowly avoid being killed.

Just after they flee the wreckage, Ellie and Robert arrive. At first, they believe the only survivor of the attack is Ian, but upon further investigation they find two footprints: one is Alan's and one belongs to one of the kids. Just then, the Tyrannosaurus returns, and Ian, Robert, and Ellie barely escape her in their jeep. Meanwhile, Dennis crashes his car, and while trying to winch it, he is killed by a juvenile Dilophosaurus, who spits out a tar-like venom at him before devouring the obese saboteur in his Jeep.

Alan, Tim, and Lex spend the night in a tree. While hiking to safety the next morning, they discover hatched eggs, which means that the dinosaurs are actually breeding. Alan hypothesizes that the frog DNA is responsible: some species of frog are known to spontaneously change sex in a single-sex environment.

Ray tries to hack Dennis' computer to turn the power back on but fails, so he does a full system restart, which requires the circuit breakers to be manually reset from the utility shed. When he does not return, Ellie and Robert follow and discover the raptors have escaped; the shutdown cut off power to the electric fences around their pit. Robert realizes that they are near and tells Ellie to go to the utility shed herself and turn the power back on while he tries to hunt them down. The raptors set a trap for Robert and he is tackled and killed by The Big One. Ellie escapes from another after discovering Ray's severed arm in the maintenance shed. After managing to turn on the power and escaping the raptor, she meets Alan, and they both go back to Ian and John in the emergency bunkers. Lex and Tim narrowly escape The Big One and her fellow raptor in the kitchen ( locking one in the freezer and knocking The Big One out for several minutes), and Lex is finally able to restore the Park's computer systems in order to call John to request a helicopter rescue of the survivors.

Alan and Ellie hold off The Big One trying to open the door to the computer room, until the power is restored, and the electromagnetic locks begin working. With the door secures, the raptor breaks into the room through the window after Grant shoots at it through the glass, and the group climbs up into the ceiling crawlspace and arrive at the Visitors Center skeleton display, only after Lex is almost killed by The Big One leaping up at her. The raptors pursue and after a scuffle with The Big One on top of the fossil exhibits and the raptors block their escape route, help comes from an unlikely source when the Tyrannosaurus suddenly appears and kills both raptors, saving Alan, Ellie, Lex, and Tim in the process. The four then climb into John and Ian's jeep and leave. Alan says he will not endorse the park, a choice with which John concurs. As all fly away in the helicopter, the children fall asleep beside Alan, who contemplatively watches a flock of pelicans flying nearby, the surviving relatives of the dinosaurs they escaped.

Dinosaurs on screen

  • [[|Tyrannosaurus|Tyrannosaurus rex]], dubbed "T. rex" informally in the film, is the star of the film according to Spielberg, being the reason he rewrote the ending for fear of disappointing the audience. Winston's T. rex animatronic stood 20 feet, weighed 17,500 pounds and was 40 feet long. Jack Horner called it "the closest I've ever been to a live dinosaur". Despite his comment, there is no scientific evidence for having a vision based on movement. The Tyrannosaurus roar is a baby elephant mixed with a tiger and an alligator and its breath is a whale's blowhole. Gary Rydstrom's dog playing with a rope toy was used for the sounds of it tearing a Gallimimus apart. Although the lead dinosaur, the T. rex is not the true villain (rather the anti-hero), with that honor going to the Raptors.
  • Velociraptor, dubbed "Raptors" in the film, also has a major role, although those depicted are not based on the actual species in question, which is significantly smaller. It was instead based on its larger relative, Deinonychus, which was at the time informally called "Velociraptor antirrhopus" by Gregory S. Paul, whose unique taxonomy was refered to by both Crichton and Spielberg. Spielberg also changed it for dramatic reasons, and when Utahraptor was discovered before the film's release, Stan Winston jokingly said "We made it, then they discovered it", responding to the coincidence of the Utahraptor's discovery after Stan Winston Studios had already designed a Raptor of near size. For the scene with Bob Peck, and several of the Kitchen shots, the Raptors are played by men in suits. Dolphin screams, walrus bellowing, geese hissing, tortoise mating call and human rasps are within the raptor sound mix. The raptor known as The Big One acts as the main antagonist of the film.
  • Dilophosaurus, dubbed "Spitter" in promotonal material for the film, was also very different from its real life counterpart, made significantly smaller to make sure audiences did not confuse it with the raptors,and also that it would not overshadow the film's star, T. rex. It has a frill and spits venom. Its vocal sounds were made by combining a swan, a hawk, a howler monkey, and a rattlesnake together.
  • Brachiosaurus is inaccurately depicted as chewing its food. Despite scientific evidence of them having limited vocal capabilities, sound designer Gary Rydstrom decided to represent them with whale songs and donkey calls to give them a melodic sense of wonder.
  • Triceratops, dubbed "Trike" in the film, has an extended cameo. Its appearance was a particular logistical nightmare for Stan Winston when Spielberg requested to shoot the animatronic of the sick creature earlier than expected. Winston also created a baby Triceratops for Ariana Richards to ride, which was cut from the film for pacing reasons.
  • Gallimimus and Parasaurolophus' roles are mainly cameos. The Parasaurolophus appearing in the first encounter with the Brachiosaurus and the Gallimimus in the scene where Dr. Grant, Lex and Tim are wandering across the open field. A herd/flock of Gallimimus come running in, with the T. rex following. The sound of a horse in heat was made up for the Gallimimus.
  • Alamosaurus (Skeleton only)



The film received mostly positive reviews from critics. As stated by Rotten Tomatoes critics, the film earned a high "B"/low "A" grade. One thing that critics disliked was the various differences between the novel and movie. And along with the film's positive feedback, it also received many awards - including the Best Science Fiction Film, Best Direction (Steven Spielberg), Best Writing (Michael Crichton and David Koepp) and Best Special Effects - as well as several other ones. Overall, the movie was a humongous success, and is also one of Spielberg's most notable works.



When the movie was released it came with a very large merchandise of games, toy lines, comics and collectables.

Main Article: Jurassic Park Film Goofs

In recent years, fans have noted many mistakes that are quite big, but because of the films fast moving pace they are mostly unnoticeable unless the movie is paused or watched again. This is some of them, but for more information see Jurassic Park Film Goofs section.

  • When the chopper comes down near the waterfall the cars are already right next to the heli pad. However once the chopper lands, they are seen backing up to collect the guests, despite already being there.
  • When the jeeps stop to look at the Brachiosarurus, they are in the sun but in the next shot they are in the shade and behind trees.
  • Also in that scene when Grant and Sattler are looking at the herd of animals, Sattler was to the left of Grant but in the next shot she is suddenly to the left of him.
  • The goat's leg that lands on top of Lex and Tim's car vanishes a few seconds later.
  • When the T. rex pushes Lex and Tims car over a stage light, a potted plant and a steel cable can be clearly seen.
  • When the Dilophosaurus that kills Nedry squirts the venom on him he grabs a bit and pulls it up to see what it is. However if one pauses the movie they can see that were he pulls the venom, there is none, but when he grabs his top he actually puts more on his chest.
  • When The Big One manages to get into Lex and Tims hiding place it is possible to see someone's hand being placed on the raptor's tail.
  • When the kids are sleeping on the helicopter in Grant's arms, their heads move position between shots.
