No wonder you're extinct.Dennis Nedry

Dennis Nedry was a computer programmer at Jurassic Park and the central antagonist of the original Jurassic Park film. Due to his financial problems and low salary, he accepted a bribe from Biosyn to smuggle dinosaur embryos off the island. His last name is an anagram of nerdy.

In both the film and the novel, he is slain by a Dilophosaurus. He was directly responsible for the events that happened in both the novel and film. A combination of factors led to his demise: despite working in a career around dinosaurs, he lacked knowledge of them, and greed, which was intertwined by desperation to pay off his debt collectors and make himself rich after that.


Jurassic Park Incident

Dennis was hired by InGen as a computer programmer for Jurassic Park. At one point, Dennis was having serious financial problems and began to reveal that InGen wasn't paying him enough to do his job. John Hammond was aware of this, but believed that Dennis was a full-grown man who could fight his own battles, as he later remarked "Your financial problems are your own". Dennis decided to accept an offer to commit industrial espionage for Lewis Dodgson to steal InGen's dinosaur embryos, which would grant BioSyn a competitive edge. In exchange, Dodgson would give Dennis $1.5 million. The two met at an outdoor food court in San Jose, Costa Rica where Lewis Dodgson gave Dennis half of his payment and a modified Barbasol can, which manned a secret compartment designed to hold 15 of the dinosaur embryos for 36 hours. Lewis also covered the cost of Nedry's meal because of his full cooperation.

Afterward, Dennis returned to Isla Nublar to go back to work, waiting until night to make his move. To access the Cold Storage Room undetected, he created Whte rbt.obj, a backdoor that would deactivate nearly all of Jurassic Park's security except the Raptor Pen. He initiated his plan after he received a call from one of Lewis Dodgson's agents at Isla Nublar's dock who told him that he would be departing the island soon because of the storm, despite Dennis wanting to do more testing on Whte rbt.obj.. Just before executing his malicious program, Dennis alerted his colleagues that he was going to get a soda and that some of Jurassic Park's security systems might be deactivated because they were compiling files so he wouldn't raise any suspicions, initiating the catalyst of the Isla Nublar Incident of 1993.

With the security deactivated and with most of Jurassic Park's workers gone to escape the storm, Dennis accessed the Cold Storage Room where he filled the modified Barbasol can with dinosaur embryos. He then proceeded to escape the Visitor Center using Jeep 12, traveling to the East Dock to drop off the Barbasol can and to get the rest of his payment. However, heavy rainfall disoriented him and also got himself lost in the wilderness, while he was driving on his way to C-3028 ship at the docks, causing him to drive off the road and accidentally crash into a fallen tree in the nearby forest. Dennis responded to this situation by getting out the jeep's rope tow to get it unstuck. While unraveling the car tow, he slipped on the mud he was standing on, which led to him losing his glasses, but something far worse was going to happen to Dennis. While tying the rope to the closest tree, a juvenile Dilophosaurus tethered around. When he deactivated nearly all of the park's security, it deactivated many of the security fences that kept the dinosaurs from escaping their paddocks (except for the Raptor Pen), allowing dinosaurs, like Dilophosaurus, to roam freely.

Dennis became uneasy upon noticing the curious Dilophosaurus that was roaming around and quickened his pace, though eventually halted his task temporarily to deal with it. Perturbed and not knowing what to do, Dennis illogically tried to distract it by getting her to play fetch, but the Dilophosaurus didn't seem to care by the stick he threw. Frustrated at his ruse failing, Dennis insulted the Dilophosaurus before proceeding to return to his vehicle, only for him to nearly slip again. When he looked back, the Dilophosaurus (having followed him) opened its frill and began intimidating him, spraying tar-like venom at him. Lucky for him, the venom missed and mostly hit his shirt, so Dennis was able to crawl away and to reach the door to his vehicle. However, the Dilophosaurus unleashed another barrage and landed a bullseye in Dennis' eyes. He screamed in agony and desperately tried to get in his jeep as his eyes burned from the poison, but he knocked his head on the roof of the jeep, causing him to accidentally drop the modified Barbasol can and it got washed away by the raging waters.

Immediately afterward, Dennis managed to get inside his vehicle. Much to his misfortune, however, the Dilophosaurus had stowed aboard into the passenger seat. With the doors of the jeep closed shut, there was nowhere for Dennis to go as the Dilophosaurus continued bombarding him with venomous spray and mauled him to death.

Because Dennis never arrived at the East Dock with the modified Barbasol can filled with embryos, two people he was supposed to meet with Miles Chadwick and smuggler Nima Cruz went to retrieve the can for Dodgson. While searching for the modified Barbasol can, Nima found Dennis' body still inside his jeep and briefly investigated his death to see if it could help her find the embryos.

His body was never recovered by the two and it is unknown if the InGen clean-up teams recovered his remains.[1]


Though Miles and Nima managed to uncover the Barbasol can from the mud, it stayed on Nublar and it was never delivered to Lewis Dodgson.

The dinosaurs that were free from their paddocks because of Jurassic Park's security fences being disabled by him caused chaos throughout the park. Though nearly all of the endorsement team and John Hammond's family were rescued during the Isla Nublar Incident of 1993, the remaining humans on Isla Nublar, including mercenary teams hired by InGen to retrieve any remaining survivors, were killed with only a few managing to escape the island. InGen suffered financially from the incident, but it managed to keep itself from bankruptcy. Four years later, Peter Ludlow took the position of CEO at InGen with the proposal of making a Jurassic Park in San Diego, Californa. However, his plan failed, only resulting in a loss of human life like the original Jurassic Park. It wasn't until 2005 that InGen, now under the ownership of the Masrani Global Corporation, created a successful dinosaur park called Jurassic World that lasted over a decade without any major incident until the creation and escaping of the deadly hybrid Indominus rex.

Through unknown circumstances, the modified Barbasol can was eventually recovered and ended up in the hands of BioSyn and Dodgson, possibly facilitating the creation of their own dinosaurs at the Biosyn Sanctuary. Twenty-nine years after the death of Dennis, Dodgson attempted to flee with the can, but was slain by a trio of Dilophosaurus, seemingly the same fate that ended for his former apprentice, Dennis.


"Yeah! Stick! Look! Stick stupid." - Dennis Nedry

"Dogson! We've got Dogson here! See, nobody cares!" - Dennis to Dodgson


Dennis Nedry, while a skilled technician, was a thickheaded, entitled, and inconsiderate man who looked down on his co-workers and was despised by them as a result. In addition, he was also very slovenly and did not look after his workspace. His actions also show that he is willing to retort to illegal and unethical tactics when he feels wronged.

Production and development

Wayne Knight teased that he would like to appear in a Jurassic World film: "It was small dinosaur and a big meal." He was suggesting that his character would wear an eye patch and have one arm.[citation needed]

  • A free project emulates Dennis' desktop including the infamous error animation Jurassic Systems.
  • Dennis uses an Apple Macintosh Quadra 700 and an SGI Crimson with Unix installed for his computers.
  • Dennis Nedry appeared in the music video to Weird Al's Jurassic Park. He is seen shutting down the park's power.
  • All three clothes Nedry wears were obviously based on all three main characters of another film directed by Steven Spielberg, The Goonies, namely Chunk, Mouth, and Mikey.
  • In Lost World, Ian criticizes Peter for twisting the facts surrounding the deaths of 3 people (Donald Gennaro, Ray Arnold and Robert Muldoon). While it is not specifically stated, it is clear that Dennis was not one of the deaths Ian was talking about, probably because Ian was unaware of his death.
  • It was unknown if he had family members since it wasn't mentioned when in a deleted scene from Lost World Peter Ludlow mentions the families of Donald Genarro, Robert Muldoon, and John Ray Arnold suing Ingen for their deaths,


  1. Ian Malcolm mentions that InGen covered up the deaths of "three people"; Peter Ludlow mentions that the families of Gennaro, Muldoon and Robert Arnold sued InGen - presumably because of the cover up. Dennis' family is not mentioned; this means his death was not known by InGen - or, if it was, it was never revealed to his family because they never sued.
