It started, as so many discoveries do, over coffee. Four Swedish researchers found themselves wondering: how many films actually feature geologists? Within minutes, they'd brainstormed a list of about ten. But their scientific curiosity wouldn't let the question rest there.
Fifteen years later, that playful inquiry has become a rigorous academic study. Erik Sturkell, a Professor of Applied Geophysics at the University of Gothenburg, is the volcanologist who decided to systematize the search. His team has now documented 141 American and British films featuring geologists—a collection robust enough for serious statistical analysis, published in the journal Geology Today.
The findings paint a remarkably flattering portrait of the profession. Eighty-five percent of geologists in cinema are portrayed as good characters, often wearing plaid shirts and driving the plot forward with their expertise. "The geologist is generally a likable character who uses his expertise to serve the story," Sturkell notes.
This stands in cheerful contrast to the fate of physicists and chemists, who film audiences will recognize as far more likely to be cast as mad scientists scheming for world domination. Geologists, it seems, have cornered the market on cinematic virtue.
That said, the profession isn't without its silver screen hazards. Thirty-two percent of film geologists—69 out of 202 characters identified—meet their ends on screen. Murder is the most common cause of death, followed by encounters with geological phenomena or, somewhat alarmingly, aliens. The team notes that the Grand Canyon became a national park as early as 1919, which may explain geology's cultural prominence in American film.
The researchers have watched nearly all 141 films themselves, a labor of love spanning more than a decade. Their first findings appeared in 2013, when roughly 60 films had been catalogued. The core conclusions, however, have remained steady: geologists tend to be the heroes, not the villains.
Dante's Peak earned the distinction of featuring the most geologists in a single film—seven characters—and remains the researchers' favorite. "It depicts most aspects of a volcanic eruption in a scientifically accurate way," Sturkell notes, even if the filmmakers combined different volcano types for dramatic effect.
There are gaps worth noting. Only 11 percent of screen geologists are women, though this proportion is increasing in newer films; in reality, researchers estimate roughly a quarter of geologists are women. A mere 3 percent of film geologists are non-white. These disparities offer rich material for future storytellers.
For Sturkell and his colleagues, the project began as intellectual play but became something more: a lens onto how science and scientists are perceived by the public. Geologists, it turns out, have an exceptionally good reputation to uphold.
