"Oh, no wonder you're extinct. I'm gonna run you over when I come back down!"
—Dennis Nedry(src)

Dennis Theodore[1] Nedry is the secondary antagonist of Jurassic Park. He was a computer programmer at Jurassic Park. Due to his financial problems and low salary, he accepted a bribe from Biosyn to smuggle dinosaur embryos off the island.

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 a $1.5 million windfall. The two met at an outdoor food court in San Jose, Costa Rica for lunch, where Lewis Dodgson gave Dennis half of his payment and a modified Barbasol can, which manned a secret compartment designed to hold 15 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 would need to create 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 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 as Dennis knew how dangerous the raptors were), allowing dinosaurs, like Dilophosaurus, to roam freely.

Dennis meets his doom

Dennis is ambushed in his jeep by the Dilophosaurus.

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 onto Dennis' face. 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 and shut the door. Just as he thought he was safe however, he quickly saw to his horror that the Dilophosaurus had stowed aboard into the passenger seat. With nowhere to run, Dennis could only scream in terror and agony as the small therapod mauled him to death.

Postmortem (game-only)[]

Dead Nedry02

Nedry's corpse.

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. Nima subsequently removed Dennis' body from the jeep in order to use it to reach the North Dock where a boat was going to be waiting for her and Miles.

Oscar Morales later mentioned that InGen was searching in Costa Rica for Dennis, unaware of his death.

Ultimately, the attempt to get the embryos to Dodgson failed with the can being either crushed by Rexy or left behind on the island.


According to the Dinosaur Protection Group, during the 1994 clean up Jeep 12 was found, along with Nedry’s remains. According to a report from a Biosyn engineer in Costa Rica on July 7, 1993, Dennis went missing during the incident. It was reported he never delivered the embryos to Biosyn.[2]

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. InGen suffered financially from the incident, but it managed to keep itself from bankruptcy.[3] 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 more 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.

The modified Barbasol can was eventually recovered 25 years later when Dodgson travels to Isla Nublar to capture dinosaurs for Mantah Corp's mind control chips. While chasing Blue the Velociraptor through the jungle, Dodgson inadvertently stumbles upon the can and the embryos, commenting that he could've used them 25 years ago just before being attacked by a pack of Dilophosaurus. Dodgson subsequently takes the can and the embryos with him, possibly facilitating the creation of Biosyn's 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, the same fate that had befallen Dennis.


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

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

"Don't get cheap on me, Dodgson." - Dennis Saying to Dodgson

"Thought you were one of your big brothers, You're not so bad." - Dennis saying to a Dilophosaurus.

"Fetch the stick boy, Look at the stick. Yes!" - Dennis taunting the Dilophosaurus using a Stick.


While a skilled technician, Dennis was a thickheaded, entitled, and inconsiderate man; he 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 was 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. It is the latter computer that Lex Murphy uses to reactivate the computerized door locks in the Control Room.
  • 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 three 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.
  • When Arnold discovers Whitrbt.obj and no employees can find Nedry, John Hammond suggests that they contact Nedry's family in New Jersey. However, in a deleted scene from Lost World Peter Ludlow mentions the families of Donald Gennaro, Robert Muldoon, and John Ray Arnold suing InGen for their deaths, but does not mention the Nedry family. A faint possibility is that Nedry had no surviving kin after his death until the timeframe of Lost World.
  • His surname of "Nedry" is an anagram of "nerdy", which was an accurate depiction of the character outside of his despicable behavior, as his legitimate career and workstation strongly suggested a nerdy personality.
  • The movie version is considered just as bad as the novel version, as the movie version was a greedy and entitled man who was eager to sell other people around him for money, while the novel version had financial problems and was abused by the novel version of John Hammond, who was far more despicable than his movie counterpart. Another difference in the novel was that Nedry intended to deliver the smuggled embyros to Dodgson, who would meet him at the dock, then Nedry planned to get back to the visitor's center to countermand his sabotage in the hopes no one would have questioned his extended disappearance.

  3. Ian Malcolm mentions that InGen covered up the deaths of "three people"; Peter Ludlow mentions that the families of Gennaro, Muldoon and Ray 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.
