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



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.
  • 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.
  • Cool Shades: Sports these in his appearance, although notably lacks them after trying to escape the Spinosaurus.
  • Jerkass: He's needlessly sarcastic and knocks out Grant.
  • 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.


Ben Hildebrand

Played By: Mark Harelik

Amanda's boyfriend.

The Dinosaurs





  • 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...
  • 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).
  • 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.
