The Kirby Family


Paul Kirby

Played By: William H. Macy

The owner of a hardware store who poses as a wealthy businessman in order to lure Grant onto Isla Sorna to help the Kirbys search for their son.
  • Bluff The Imposter: Paul is tricked by Billy into revealing that he never climbed K2, like he'd earlier claimed. From there, his lies quickly unravel.
  • Bumbling Dad: To Eric. Paul is a typical suburbanite father; he's well-meaning, but clumsy, lacking in useful experience or knowledge and is pretty far from an action hero. Still, he causes less damage than Amanda.
  • Chekhov's Hobby: He casually remarks to Amanda that he'd taken up swimming. It comes in useful when the group are attacked on the river by the Spinosaurus.
  • Disney Death: He seemingly falls to his death from a crane, but hilariously turns out to be okay.
  • The Everyman: Despite initially posing as a millionaire, he's more of an average joe and moderate businessman who owns "Kirby Paint and Tile Plus". He has very few skills that are useful when trapped on an island with dinosaurs.
  • First Father Wins: It's heavily implied that he gets back together with Amanda after escaping the island with her and Eric.
  • Papa Wolf: He might be a Bumbling Dad, but he's still a Dad. He expends enormous resources to find his son, willingly going through absolute hell to save him. This includes hiring mercenaries, tangling with dinosaurs on a hostile island, and being alone for long periods with Amanda.
  • Relationship-Salvaging Disaster: A few brushes with death helps push Amanda and Paul back together.
  • Took a Level in Badass: Paul is just a schlubby, divorced small-business owner. By the end, he's taken on a Spinosaurus and survived.
  • Working with the Ex: He's actually divorced from Amanda, despite them putting up a pretence when meeting Alan. They still snipe and bicker with each other; Amanda is slightly more vitriolic than him, however.


Amanda Kirby

"This is how you make dinosaurs?"
Played By: Tea Leoni

Paul's ex-wife who accompanies the group to Site B, feeling guilty for having lost Eric and Ben.


Eric Kirby

Played By: Trevor Morgan

The 12-year-old son of Paul and Amanda who ends up stranded on Site B for eight weeks, and must fend for himself.
  • Action Survivor: He survived a crash that killed his mother's boyfriend and spent the next 8 weeks surviving on an island of dangerous animals completely alone.
  • Genre Savvy: Justified because he was stuck on the island for a while. When you're trapped on an island filled with aggressive animals, you either learn about survival tactics or you die.
  • Giving Them the Strip: He abandons his jacket to escape a swarm of baby pteranodons. Subverted because it works for about half a second before they go after him again. Plus they can fly.
  • Wise Beyond Their Years: He's very practical for a kid his age, understandable considering he had to dodge dinos for over eight weeks. This makes him the only useful member of the Kirby family for much of the film.

Kirby's Mercenaries



"If we split up, I'm going with you guys."
Played By: Michael Jeter

A meek but sardonic mercenary "booking agent" who travels with his two associates to the island when the man who was supposed to go falls ill.
  • Badass: In a deleted scene, just before his death, Udesky fends off the Velociraptors with nothing but a branch.
  • Butt Monkey: Nothing good happens to Udesky. He's trapped on an island full of deadly animals with a very annoying couple, gets tortured and killed by the raptors and he isn't even a real mercenary. Hell, he wasn't even meant to be here today!
  • Cruel and Unusual Death: The raptors cripple him and leave him to lie in agony as bait to lure out the protagonists. When they realise the humans didn't fall for their little trap, they snap his neck.
  • Deadpan Snarker: He's one of the more sarcastic characters; it's the only way to stay sane around the Kirbys.
  • Nice Guy: Udesky is a rather polite man and isn't quite a ruthless mercenary. He reveals he wasn't supposed to go along as he's more like the booking agent of the small mercenary outfit and was filling in for another unseen mercenary who called in sick.
  • Only Sane Man: Mixed with Unfazed Everyman.



Played By: John Diehl

A tough and quiet mercenary.
  • Alas Poor Jerkass: He's unpleasant but not a villain. It's also hard not to feel sorry for the poor guy, betrayed by his cowardly friend and begging to be rescued as death approaches.
  • Cool Shades: He's seen sporting them on the plane, although notably lacks them after trying to escape the Spinosaurus.
  • Deadpan Snarker: Cooper has a rather sardonic sense of humor, as we find out on the plane:
    Udesky:Cooper! If you see anything, yell up!
    Cooper: Naw, I thought I'd keep it to myself!
    • And:
    Billy: How do you know the Kirbys?
    Cooper: Through our church.
  • Jerkass: He's needlessly sarcastic, seems pretty trigger-happy and knocks out Grant despite there being little need to.
  • Not So Stoic: Most of the time, he has a bored expression and a dry wit. When the Spinosaurus comes for him, his tough guy exterior melts away.
  • Tears of Fear: When trying to escape the Spinosaurus, he jumps in the path of the plane, begging them to stop and weeping when it's clear they won't.
  • Those Two Guys: With Nash.


M.B. Nash

Played By: Bruce A. Young

Kirby's mercenary pilot.
  • Ace Pilot: His role in the mercenary group.
  • Dirty Coward: In his hurry to flee the island, Nash leaves Cooper to die.
  • Just Desserts: He's not a villain exactly, but his Dirty Coward tendencies mean that his death feels a little deserved.

Other Characters


Billy Brennan

Played By: Alessandro Nivola

A young and overenthusiastic graduate student at Grant's dig site. He accompanies Grant to Isla Sorna and gets stranded on it with him and the Kirby's.
  • Alliterative Name: Billy Brennan.
  • Badass: He paraglided into a flock of Pteranodons and managed to hold his own just long enough to save Eric's butt. The best part? Even after being pecked repeatedly by the things, he survives!
  • Chekhov's Hobby: He mentioned being a proficient paraglider.
  • Disney Death: Seemingly pecked to death by a pair of Pteranodons but somehow manages to survive.
  • Heroic Sacrifice: Subverted, he manages to survive his encounter with the blood-thirsty dinos.
  • Nice Job Breaking It, Hero: Billy's theft of raptor eggs leads to numerous dangerous situations, ultimately resulting in Udesky's death.
  • Not Quite Dead: Again, seemingly killed by pteranodons, still alive afterward.
  • Reckless Sidekick: To Dr. Grant. You don't get much more reckless than stealing Velociraptor eggs.
  • Well-Intentioned Extremist: He steals raptor eggs, inadvertently getting Udesky killed.
    Billy: You have to believe me, this was a stupid decision but I did it with the best intentions.
    Grant: With the best intentions? Some of the worst things imaginable have been done with the best intentions. You know what, Billy? As far as I'm concerned, you're no better than the people that built this place.


Ben Hildebrand

Played By: Mark Harelik

Amanda's boyfriend.
  • Body Horror: There's really not much left of the guy when they find him.
  • Forgotten Fallen Friend: Despite being Amanda's boyfriend, she isn't overly concerned that he met a horrible fate. She screams when she sees his corpse, but that's her default reaction anyway. She then tells Paul she's not upset about Ben, but about her son, who's still missing. Justified in that any good parent is going to care more about their child then their short-term lover.
  • Peekaboo Corpse: Say hi to your boyfriend, Amanda.


Enrique Cardoso

Played By: Julio Oscar Mechoso

A Costa Rican boat captain who operated an illegal parasailing trip around Isla Sorna called Dino-Soar.
  • What Happened to the Mouse?: Exactly what happened to Enrique is a point of contention among fans. It's understood that he dies, but how? Word of God is that some Pteranodons killed him, but it seems odd that Ben and Eric weren't also attacked when they were high in the air. Another theory is that the Spinosaurus killed him, since it's shown as a powerful swimmer but Enrique was out relatively far from the island.

The Dinosaurs



"Obviously a super-predator."

Billy: That's a Tyrannosaurus.
Grant: I don't think so. It sounds bigger.

  • Always a Bigger Fish: It kills the Tyrannosaurus Rex after it starts to pursue the heroes.
  • Animals Not to Scale: The fifty-something foot long monster in the movie is actually smaller than the real animal! And ironically taller than the real animal, according to 2014 studies.
  • Big Bad: It's the biggest carnivore on the island and the most threatening creature the team faces.
  • Breakout Villain: The most memorable thing this movie did was put Spinosaurus on the map.
  • The Croc Is Ticking: Cooper's cell phone is still ringing in its belly...somehow.
  • Giant Swimmer: It can hunt the group in the water as well as on land. Nowadays this is considered its main hunting method.
  • Historical Badass Upgrade: The real Spinosaurus, despite being huge and powerful, preferred to eat fish over red meat (but would have eaten both, if it got the chance. After all, when you are aquatic you get to have more chances at a fish.). Here, it's depicted as the ultimate superpredator who eats T. rexes for breakfast. It could have killed a tyrannosaur, but not on land.
  • Historical Villain Upgrade: Jeez did they make this thing into a monster! Much like the raptors in the previous two movies, it comes off less as an animal acting on instinct and more like a bloodthirsty serial killer.
  • Kaiju: Pretty much what it's been turned into.
  • Karma Houdini: It flees at the end of the final confrontation.
  • Never Smile at a Crocodile: It has jaws like a crocodile, just like the real deal.
  • Non-Malicious Monster: Averted. This thing is almost sadistic in the way it hunts the main characters.
  • Prehistoric Monster: It doesn't so much act like an instinctual animal as opposed to menacing the humans apparently out of malice. The same humans who shredded part of its hide with an airplane's propellers.
  • Super-Persistent Predator: It hunts and stalks the group throughout the movie.



Amanda: For what?

  • Adaptational Badass: In the books, the pterosaurs of Jurassic Park still had grasping talons but were too weak to lift Lex (a small child). Here they're capable of carrying full grown adults to their doom.
  • Adaptation Species Change: According to the Jurassic Park books, Jurassic Park had no Pteranodons. The park's token pterosaurs were Cearadactylus (erroneously referred to as "Cearadactyls")
  • All Flyers Are Birds: Possibly invoked.
  • Ambiguous Gender: We can assume that most of them are female, due to how Jurassic Park startednote . However, we don't get any real signal as to what gender they are. Even more confusing, all of them have huge crests on their heads, despite the fact that in in real life only male pteranodons had large crests.
  • Breakout Villain: Moreso than the Spinosaurus even. They were advertised just as much, but much less polarizing to the audience.
  • Death Glare: One of them gives this to Grant.
  • Giant Flyer: About the only accurate thing about them is their massive wingspans.
  • Kidnapping Bird of Prey: Poor Eric.
  • Killer Rabbit: The babies. They're so cute! And oh so deadly...
  • Historical Badass Upgrade: Much stronger and scarier than the real animal.
  • Historical Villain Upgrade: The real life Pteranodon was about as dangerous as a super-sized pelican (though then again...), but these ones are depicted as vicious human-killing predators.
  • Non-Malicious Monster: Much like T.Rex in the first film, the Pteranodons were only attacking the group because they were hungry and/or wanted to protect their turf.
  • Ptero Soarer: Probably justified because of the cloning process messing with their DNA. At least they're quadrupedal (unlike the Pteranodon from the previous movie).
  • Put on a Bus: They fly away at the end of the film. The next film reveals that Hoskins killed them.
  • Toothy Bird: While many pterosaurs had teeth, Pteranodon (who's name means "Wings Without Teeth") was not one of them.
  • Zerg Rush: The babies attack in this way.

    Tyrannosaurus rex 

Tyrannosaurus rex

The famous predator who is defeated by the Spinosaurus.
  • The Bus Came Back: Subverted; this T. rex is implied to be a grown up version of the baby one from the previous film. After returning, however, it dies.
  • Neck Snap: How the Spinosaurus kills it.
  • The Worf Effect: An infamous example, it's eaten by the Spinosaurus.



  • Big Bad: For once, averted. This time, they have a good reason for their attacks.
  • Feathered Fiend: Partially feathered, anyway, though the males have more feathers than the females.
  • It Can Think: The smartest iteration of the raptors so far.
  • Mama Bear and Papa Wolf: Their motivation.
  • More Deadly Than The Male: Implied, seeing as the alpha male appears to be second-in-command to his mate, who appears to make most of the decisions between them.
  • Non-Malicious Monster: All they want is their eggs.
  • Number Two: The alpha male, to his mate.
