Honestly, if you grew up in the late 90s, you probably have a very specific, very irrational fear of hot tubs and rowboats. You can thank Pierce Brosnan for that. Specifically, his turn as Harry Dalton in the 1997 disaster epic Dante's Peak.
It’s been decades, but whenever someone mentions a Pierce Brosnan volcano movie, this is the one that bubbles up to the surface. It was part of that weird 1997 trend where Hollywood decided we needed two movies about the same terrifying thing at the exact same time. We had Dante's Peak in February and Volcano with Tommy Lee Jones in April. But while Tommy Lee Jones was busy trying to punch lava in Los Angeles, Pierce was actually trying to do some science. Sorta.
What Really Happened With Dante's Peak?
The setup is basically a classic disaster trope. Harry Dalton is a guy who has seen too much. He lost his wife to a volcano in South America—a brutal opening scene that sets the stakes—and now he’s a cynical expert for the USGS. He gets sent to this idyllic town in the Cascades because the mountain is "clearing its throat."
The town is gorgeous. It’s actually Wallace, Idaho, in real life, which is a place you can still visit if you want to see where they filmed the ash-covered chaos. Linda Hamilton plays the mayor, Rachel Wando, who is also a single mom trying to save her business.
It starts slow. A couple of skinny-dippers get boiled alive (the aforementioned hot tub trauma). Some trees die. The water starts smelling like rotten eggs because of the sulfur. Harry is the only one who cares, while his boss, Paul, basically tells him to chill out so they don't ruin the town's economy. It’s basically Jaws, but with a mountain instead of a shark.
Why the Science is Kinda... Good?
Here is the thing most people get wrong about this movie: it’s actually surprisingly accurate. Most disaster movies just make stuff up, but the team behind Dante's Peak actually talked to the United States Geological Survey (USGS).

- The Signs: The movie correctly identifies things like $SO_2$ (sulfur dioxide) gas levels, seismic swarms, and PH changes in the water as precursors to an eruption.
- The Ash: That "snow" falling from the sky? In reality, it was mostly shredded paper and cellulose insulation. But the way it’s depicted—clogging car engines and collapsing roofs—is exactly what happened during the 1980 eruption of Mount St. Helens.
- The Pyroclastic Flow: That terrifying wall of hot gas and rock at the end? That’s a real thing. It moves at hundreds of miles per hour. You don't outrun it. You just... don't.
But then, because it's Hollywood, things get a little silly.
The Grandma, The Boat, and the Acid Lake
We have to talk about the lake scene. You know the one.
Grandma Ruth, who refuses to leave her mountain cabin because she’s stubborn, ends up trapped with Harry, Rachel, and the kids. They have to cross a lake that has suddenly turned into pure acid. Why? Because volcanic gases like carbon dioxide and sulfur dioxide dissolved into the water.
In real life, this happens. There are crater lakes with a pH of 0.5. But it doesn't happen in ten minutes. And it definitely wouldn't eat a metal boat that fast while leaving the people inside mostly fine until the very end.
The scene where Grandma jumps into the water to pull the boat to shore is the peak of the movie's "science-fantasy" blend. Her legs are destroyed by the acid, but Harry manages to use his jacket-wrapped arm to paddle a bit without his skin melting off immediately. It’s harrowing. It’s iconic. It’s also totally scientifically impossible at that speed.

Driving Over Lava: Don't Try This
There is another scene where Pierce Brosnan drives a suburban over a "crust" of moving lava.
Expert tip: Do not do this.
Lava is roughly $1,700^\circ F$. Even if the top looks solid, the heat alone would ignite the gasoline in your tank and melt your tires before you even got the front wheels on it. The movie uses pahoehoe lava (the runny, ropey kind) which you usually find in Hawaii, not the Cascades. But hey, it looks cool on a cinema screen.
The Box Office Battle: Dante's Peak vs. Volcano
Universal Pictures spent $116 million on this movie. That was a massive budget for 1997. They were in a literal arms race with 20th Century Fox to get their movie out first.
Universal won the race by moving their release date to February. It worked. Dante's Peak made about $178 million worldwide. It wasn't a "Titanic" level hit, but it did much better than Volcano, which felt more like a cheesy B-movie. Dante's Peak felt like a "real" movie because of the location filming and the chemistry between Pierce and Linda.

Brosnan was at the height of his James Bond fame here. He had just done GoldenEye a couple of years before. Seeing Bond as a nerdy geologist who actually knows how to use a radio was a fun subversion of his persona.
Is it Worth a Rewatch?
Honestly? Yes.
The practical effects hold up way better than the CGI of the era. They used actual miniatures for the town destruction, and the ash looks tactile and oppressive. It doesn't feel like a cartoon.
If you're looking for a thrill, or just want to see a pre-CGI era disaster film that actually respects the power of nature, this is the one. Just remember: if the water in your tap starts smelling like eggs and the mountain starts "throat-clearing," listen to the guy who looks like 007 and get out of town.
Actionable Takeaways for Movie Buffs
- Visit the Site: If you're a film nerd, go to Wallace, Idaho. The town still looks remarkably like it did in the film, and the locals have plenty of stories about the time Pierce Brosnan came to town.
- Check the Facts: If you want to see the real-life inspiration, look up the 1980 Mount St. Helens eruption. The filmmakers used news footage of the actual crater for the final shots of the movie.
- Watch the Competition: Watch Volcano (1997) right after. It's a hilarious study in how two studios can take the same prompt and create two completely different vibes—one a grounded thriller, the other a campy action flick.
The Pierce Brosnan volcano movie remains the gold standard for geological disasters because it dared to make the mountain the lead actor. It wasn't about a villain or a conspiracy; it was just about a big rock that decided to wake up on the wrong side of the tectonic plate.
