Characters featured in Jurassic Park III.

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.
  • Bumbling Dad: He stutters quite a bit, and he can be a little clumsy sometimes.
  • Disney Death: He seemingly falls to his death from a crane, but hilariously turns out to be OK.
  • The Everyman: Like many of the characters William H. Macy plays.
  • First Father Wins: Took Amanda a long while before she realized that she should stick with Paul.
  • Papa Wolf: For his son, Eric, who he goes through hell to save.
  • Took a Level in Badass: Paul is just a schlubby, divorced small-business owner. By the end, he's taken on a spinosaurus.
  • Working with the Ex: He's actually divorced from Amanda, despite them putting up a pretence when meeting Alan.


Amanda Kirby

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.
  • Wise Beyond Their Years: 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.
  • Nice Guy: Reveals he wasn't supposed to go along as he's more like the 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.


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.

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.
  • Mr. Fanservice: Not a bright man, but certainly a very attractive one.
  • 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.

The Dinosaurs



  • 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.



  • 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.
  • 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.
