Let’s be real for a second. If you grew up in the early 2000s, you probably remember the high-pitched, frantic yelling of Amanda Kirby echoing through your living room speakers. Téa Leoni in Jurassic Park III is often cited as one of the most polarizing figures in the entire franchise. People love to hate her. They call her annoying. They say she’s a "screamer."
But honestly? If your kid was lost on an island full of genetically engineered monsters, you’d probably be a bit of a wreck too.
The hate for Leoni's character, Amanda Kirby, has become a sort of internet meme over the last two decades. Yet, when you look at what she actually brought to the table, there’s a lot more nuance there than just "lady with a bullhorn." She wasn't a paleontologist like Alan Grant or a survivalist. She was a mom from Oklahoma. And that’s exactly why her performance works, even if it makes you want to cover your ears.
The Bullhorn Incident and Why Fans Can't Let It Go
The most famous—or infamous—scene involves Amanda using a megaphone to shout for her son, Eric, while standing in a wide-open field on Isla Sorna.
Stupid? Absolutely.

In a world where sound attracts giant predators like the Spinosaurus, it’s basically ringing a dinner bell. But Téa Leoni plays this with a desperate, localized tunnel vision. She isn't thinking about the food chain. She's thinking about her twelve-year-old son who has been missing for eight weeks.
- The Intent: Director Joe Johnston wanted the Kirbys to feel like "regular people."
- The Reality: They were the ultimate "anti-experts" compared to the sleek, capable teams in the first two films.
- The Backstory: Interestingly, Leoni has mentioned in interviews that she was going through a traumatic time in her own life—her daughter had been severely ill—which she channeled into that "mother bear" energy.
The contrast between her raw, messy panic and Sam Neill’s world-weary Dr. Grant is what drives the movie's tension. Grant is trying to survive; Amanda is trying to save. Those two goals don't always align, and that friction is where the movie finds its heart, even if that heart is occasionally screeching at a high decibel.
Tea Leoni Jurassic Park: A Role That Almost Didn't Happen
Believe it or not, the script for Jurassic Park III was famously unfinished when filming began. It was a mess.
Leoni and her co-star William H. Macy (who played her ex-husband, Paul Kirby) often had to improvise or deal with pages that were literally being written as they walked onto the set. That’s a nightmare for any actor, let alone one expected to lead a multi-million dollar blockbuster.
Leoni has joked about the experience, calling it one of the most fun but bizarre projects of her career. One day you’re acting against a giant animatronic head, and the next, you’re reacting to a guy with a plastic bag on a stick.

During the filming of the Spinosaurus attack on the river—one of the film's better sequences—Leoni actually sustained minor lacerations. The physical toll of being dragged through muddy water and slammed against prop trees was real. She wasn't just standing on a green screen; she was in the trenches.
What Most People Get Wrong About Amanda Kirby
Critics usually complain that she’s a "damsel in distress," but is she really?
Think about it. She’s the one who organizes the "tour" to get back to the island. She tricks a famous scientist. She faces off against raptors and a Pteranodon. By the end of the film, she’s the one using the raptor resonating chamber to help save the group.
She evolves. She goes from a frantic mess to someone who can actually handle herself in a crisis. It’s a classic arc that often gets overlooked because people are too busy focusing on her volume level.

Why Jurassic Park III Still Matters in 2026
It’s easy to look back at the original trilogy and see the third installment as the "red-headed stepchild." It was shorter, leaner, and felt more like a B-movie monster flick than a grand Spielbergian epic.
But there’s a reason it’s grown a cult following.
It’s fast. At 92 minutes, it doesn't overstay its welcome. And a huge part of that frantic energy comes from Téa Leoni. She keeps the stakes feeling personal. Without the Kirbys, Jurassic Park III is just a bunch of scientists walking through the woods. With them, it’s a family drama wrapped in a survival horror.
Actionable Takeaways for Movie Buffs
If you’re planning a rewatch of the franchise, here’s how to actually appreciate Leoni’s performance:
- Watch the body language: Notice how Leoni’s posture changes from the beginning of the movie (slumped, nervous) to the end (alert, protective).
- Listen to the silence: Some of her best moments aren't when she's screaming, but when she's looking at the abandoned InGen labs, realizing the scale of the horror her son was trapped in.
- Compare it to The Lost World: Julianne Moore’s character in the second film makes arguably "dumber" scientific mistakes, but she gets half the flak. Ask yourself if the "annoying" label is just a byproduct of her being a "civilian" character.
Téa Leoni might not be the hero we wanted in a dinosaur movie, but she was the most "human" character the series had seen up to that point. She was flawed, loud, and terrified. Honestly? Most of us would be too.
