Jaws (1975)

Steven Spielberg’s Jaws forever changed the way people looked at sharks. The story of a rogue great white terrorizing the fictional town of Amity Island became the first true summer blockbuster and remains one of the most influential thrillers ever made. Ironically, the film showed surprisingly little of the shark because the mechanical model, nicknamed Bruce, kept malfunctioning during production.

The movie’s impact stretched far beyond the box office. Many people began viewing sharks as bloodthirsty predators, even though attacks on humans are extremely rare. Author Peter Benchley, who wrote the book on which the film is based, later became a passionate shark conservation advocate and admitted he regretted helping reinforce that stereotype after learning more about these remarkable creatures.

King Kong (1933)

Long before computer-generated creatures (unfortunately) ruled Hollywood, audiences were amazed by King Kong , the giant ape brought to life through stop-motion animation . The film introduced one of cinema’s greatest icons, but it also reinforced the old idea that gorillas were savage monsters lurking in mysterious jungles.

Modern science tells us a very different story. Real gorillas are intelligent, gentle, highly social animals that spend most of their time eating plants and caring for family groups. Conservationists helped transform public understanding of great apes, showing that they’re far more vulnerable to humans than humans are to them.

3

The Birds (1963)

Alfred Hitchcock proved that almost anything could become terrifying, even pigeons and seagulls . The Birds imagines a scenario in which ordinary birds suddenly begin attacking people — without any explanation. That uncertainty became one of the film’s greatest strengths.

In reality, birds rarely attack humans, except when defending their nests or chicks during breeding season. The movie helped define the "nature strikes back" genre, but outside the theater, your neighborhood flock is much more likely to steal a French fry than launch a coordinated assault.

Cujo (1983)

Few movie dogs have inspired as much fear as Cujo , the enormous St. Bernard whose rabies transforms him from a lovable family pet into a relentless killer . Based on Stephen King’s novel, the film left many viewers unfairly suspicious of one of the world’s gentlest breeds.

Actual St. Bernards earned their reputation in a completely different way. For centuries, monks at Switzerland’s Great St. Bernard Pass bred these dogs to rescue stranded travelers crossing the snowy Alps. They’re famous for patience, loyalty, and calm temperaments, not aggression.

5

Arachnophobia (1990)

For people who already disliked spiders, this movie certainly didn’t help. Aracnophobia mixed horror with comedy as a deadly fictional spider species spread terror through a quiet California town , turning every corner of the house into a potential danger zone.

The truth is much less dramatic. Scientists have identified roughly 50,000 spider species, but only a tiny percentage can seriously harm humans. Most spiders spend their lives quietly eating insects and avoiding people whenever possible, making them surprisingly helpful roommates.

6

Anaconda (1997)

The Amazon rainforest became home to one of Hollywood’s biggest reptilian villains in Anaconda . The enormous snake hunts humans with impossible speed, intelligence, and appetite , creating a memorable creature feature starring Jennifer Lopez, Ice Cube, and Jon Voight.

Real green anacondas are certainly impressive; they’re among the heaviest snakes on Earth, but humans aren’t on their menu. Their natural diet consists mainly of fish, birds, capybaras, caimans, and other wildlife. The movie’s giant snake was far larger than anything scientists have ever documented.

7

The Grey (2011)

After surviving a plane crash in the Alaskan wilderness, the characters in The Grey face another nightmare: a relentless pack of wolves that seems determined to hunt every survivor . The tense survival story became one of Liam Neeson’s most memorable performances.

Wildlife biologists, however, were quick to point out that wolves almost always avoid people. Fatal attacks in North America are extraordinarily uncommon, and healthy wolf packs generally prefer staying as far away from humans as possible.

8

Orca (1977)

Released only two years after Jaws , Orca offered another giant marine predator, this time driven by revenge after humans kill its mate . Unlike many monster movies, the whale is portrayed with emotion and intelligence, yet it’s shown relentlessly attacking people.

Today’s marine researchers describe orcas as highly social animals with complex family relationships and remarkable communication skills. Despite the nickname "killer whale," there are no verified records of a wild orca killing a human.

9

Willard (1971)

Before audiences feared sharks, they feared rats. Willard tells the story of a lonely man who commands an army of rodents , turning one of humanity’s oldest urban fears into a classic of psychological horror. Its success even inspired the sequel Ben , featuring a theme song sung by a young Michael Jackson.

Real rats are much more impressive than their reputation suggests. They’re highly intelligent mammals capable of solving problems, learning complex tasks, and even detecting diseases in scientific research. Many people today happily keep domesticated rats as affectionate pets.

10

The Ghost and the Darkness (1996)

Unlike many entries on this list, this film is rooted in a real historical event. During the construction of the Uganda Railway in Kenya in 1898, two male lions attacked railway workers near the Tsavo River , creating one of history’s most famous wildlife mysteries.

Scientists still debate exactly how many people the lions killed, and the preserved animals remain on display at Chicago’s Field Museum. Although the true story was extraordinary, man-eating lions are exceptionally rare, and healthy wild lions generally avoid human contact whenever possible.

11

Monkey Shines (1988)

George A. Romero traded zombies for primates in this psychological horror film about a helper capuchin monkey whose protective instincts spiral into something much darker . The story blurred the line between companionship and obsession, leaving viewers uneasy about intelligent animals.

Capuchin monkeys really are among the smartest New World primates and have even been trained to assist people with disabilities. At the same time, experts strongly discourage keeping monkeys as pets because they remain wild animals with complex social and behavioral needs.

12

Frogs (1972)

Despite its title, Frogs is surprisingly unfair to amphibians. While frogs appear throughout the movie, most of the actual attacks are carried out by snakes, insects, turtles, and other wildlife during a bizarre uprising against environmentally destructive humans.

Outside Hollywood, frogs are among nature’s most valuable allies. They consume enormous numbers of insects and serve as important indicators of environmental health. If frogs begin disappearing from an ecosystem, scientists often see it as an early warning that something is seriously wrong.

Measuring

This is a difference most Americans are aware of: most countries use the metric system rather than U.S. customary units, and most use Celsius instead of Fahrenheit. Countries such as the UK and Canada still use some imperial units in everyday life, but they mainly use the metric system. Another measure that confuses foreigners is the particular way ingredients are measured in American recipes, which often use cups, tablespoons, and teaspoons rather than measurements by weight.

Fun fact: The only other countries that use the Imperial system officially are Liberia and Myanmar.

2

Sales tax

Do you find having to calculate sales taxes annoying? That’s a unique American experience. In the majority of the world, the price you see is the price you pay , because it has the sales tax already added.

Why is it different in America? Sales taxes vary across states , so retailers find it easier to showcase the base price and then calculate the total at checkout.

3

Cutlery use

Many Americans abroad are surprised by the realization that not everyone uses a knife and fork in the same way they do . In fact, no one else does. While most Americans have learned the American style —also called the zig-zag or fork switching method— that involves using the fork in the left hand for cutting and then changing it to the right to pick up the food, European and Latin American countries don’t do this . It might seem like a small difference, but it completely changes the way you eat.

4

Iced drinks

Do other countries not have ice? They do, but they don’t necessarily assume everyone will want it. While serving water and other beverages with ice is customary in America, in many other countries, you need to request it —even during the hottest of summers.

But even if you get ice, many times you will need to specify the amount : the same drink that would be filled with ice cubes in America might come to you with just two or three cubes elsewhere.

5

Date formatting

The U.S. is not completely alone on this one, but there’s a difference big enough to be worth mentioning. The standardized way of recording the date in America is month-day-year , a convention also followed by some Caribbean and Asian countries. But in the rest of the Western world, the conventional format is day-month-year , which can lead to confusion for Americans. In most Asian countries , the most commonly used format is year-month-day .

6

The word ‘American’

In the English language, ‘American’ is the only way to refer to people with U.S. citizenship . Other words, such as ‘Usian’ or ‘Unitedstatian’ have been proposed, but never stuck. This is why many Americans are surprised when other countries —Latin American countries in particular— use ‘American’ for anyone in the American continent , or continents, another big difference. In most European and Latin American countries, there is a different word for U.S. citizens, such as the Spanish ‘estadounidense’ or the Portuguese ‘estadunidense’ .

7

Moving out at 18 years old

This one is not so black and white, but more like a general tendency. Compared with most of Europe, Latin America, and Asia, Americans give serious consideration to the possibility of moving out after high school. Not everyone does, and not everyone can afford it, but it's fairly common.

In other countries, young adults generally move out if their job or education requires it , but they tend to stay at home a few more years if they can.

8

Driving a car as a teenager

America is quite car-centric , especially if you live outside of the big cities. While not everyone can afford to have a personal car —even a second-hand one—, it is common for 16 and 17-year-olds to legally drive their parents’ car, or save for their own.

In the rest of the world, the chances of high schoolers driving themselves to school are much lower, as most countries don’t allow underage kids to get a driving license .

9

Solo cups

Do plastic cups exist outside of the U.S.? They do, but they are not as iconic or as widely used as Solo cups, introduced in the 1970s as a disposable but sturdy cup for parties and events. Many foreigners visiting America are surprised when they realize that solo cups are a real thing , and not something that just happens in movies.

10

Filing taxes

Taxes in the U.S. are not that different from taxes in other countries, except for how they are filed . During tax filing season, thousands of Americans direct their efforts to ensure they have properly reported their income and that their return will match the IRS’s data.

In other parts of the world, however, the one responsible for calculating and filing taxes is the government , while citizens merely corroborate that everything is in order.

Dundas Castle, Roscoe, New York

Image: Annie Spratt

Also known as Craig-e-Clair, this castle was built by Ralph Dundas in the early 20th century. It is an architectural marvel of stone and copper.

Dundas died before the castle was completed, and his wife was reportedly committed to a sanitarium shortly after. Consequently, no member of the Dundas family ever actually lived in the mansion. This has led to the "Ghost of Dundas Castle" legends, with locals claiming to see a woman in white wandering the unfinished halls, waiting for a housewarming party that never happened.

Rockwell House, Milledgeville, Georgia

Image: Clem Geiss

Built in 1838, the Rockwell House is a stunning example of Federal-style architecture, but its beauty is shadowed by a dark past. It was originally built for Colonel Samuel Rockwell, a prominent lawyer.

Local lore whispers about the "Rockwell Ghost," believed to be a young girl who died during a yellow fever outbreak. However, the house’s most tangible secret lies in its survival; it has endured multiple fires and periods of extreme neglect. In recent years, it has become a focal point for preservationists who uncovered hidden structural reinforcements that suggest the house was built to be an impenetrable fortress of its era.

3

Elda Castle, Ossining, New York

Image: Nitrogel

If the name David Abercrombie sounds familiar, it’s because he co-founded the clothing company Abercrombie & Fitch . But in the 1920s, he also built this granite castle, named Elda (an acronym of his children’s names), as a secluded retreat.

The castle features a network of spiral staircases and open-air porches designed to blend the indoors with the rugged wild. Its abandonment, however, is a sheer tragedy. After the family moved out, the castle was used as a research facility and later fell victim to vandals. Legend has it that a fire in the 1940s was started by squatters, leaving behind a charred stone husk that resembles a medieval ruin more than a 20th-century home.

Mongo's Castle, Memphis, Tennessee

Image: Denny Müller

A stark contrast to the classical mansions of the South, Mongo’s Castle was the passion project of Mongo Bebe, a man who built his home out of scrap stone, Ashlar blocks, and found materials.

The house is a maze of folk-art eccentricity. The builder intended it to be a community center and a symbol of African-American heritage and self-reliance. It stands today as a decaying puzzle, with many neighbors still unsure of the structural logic behind its towering, uneven walls.

5

Bannerman's Castle, Pollepel Island, New York

Rising from the Hudson River, this castle was never intended to be a home; it was a giant advertisement and warehouse for Francis Bannerman VI’s military surplus empire.

In 1920, 200 tons of gunpowder and shells exploded in the castle’s powder house, blowing out a significant portion of the walls. The ground is still considered unstable due to the remnants of military munitions, and the inscriptions on the walls are actually warnings and advertisements for the Bannerman business. Do you dare visit this mansion?

6

Castle Mont Rouge, Rougemont, North Carolina

Image: Florian Delée

This whimsical, onion-domed castle looks like it belongs in the Russian countryside rather than the North Carolina woods. It was designed by sculptor Robert Mihaly, but he ended up abandoning the project in the early 2000s following a personal tragedy and financial hurdles.

The castle remains an "empty sculpture," filled with intricate marble work and unfinished turrets. The bizarre architectural fusion lacks a standard floor plan, making it nearly impossible to convert into a functional residence without destroying its artistic integrity.

7

Ha Ha Tonka Castle, Camdenton, Missouri

Image: Hannah McBride

Robert Snyder, a wealthy Kansas City businessman, began building this European-style castle in 1905. He wanted a retreat that overlooked the breathtaking Ha Ha Tonka Spring.

Yet, Snyder never got to see his dream finished; he was killed in one of Missouri’s first recorded automobile accidents just a year after construction began. His sons finished the castle, but it was gutted by a fire in 1942. There’s a hidden network of caves beneath the castle, which were rumored to be used by outlaws and later as a natural "refrigerator" for the estate’s kitchen.

Carleton Island Villa, Cape Vincent, New York

This once-magnificent villa was built for William Wyckoff, who made a fortune with the Remington Typewriter Company.

The Secret: Wyckoff’s dream turned into a nightmare on the very first night he stayed in the house. He suffered a massive heart attack and died in his sleep. His wife had passed away a month prior, leaving the villa to a son who had no interest in it. The house has stood empty for over 70 years, its secret being the tragic "cursed" timing that prevented it from ever functioning as a family home.

9

Dicksonia Plantation, Lowndesboro, Alabama

Image: Theo Bickel

Dicksonia was a quintessential antebellum mansion, featuring the massive columns and wrap-around porches synonymous with the Old South.

Unlike many plantations that were destroyed during the Civil War, Dicksonia survived the conflict only to be destroyed by a mysterious fire in 1939. Its "ghost pillars," however, remained standing long after the wooden house burned away. These towering brick columns became a haunting landmark , representing the structural skeletons of a forgotten social order.

10

Wyndcliffe, Rhinebeck, New York

Image: Peter Herrmann

This house is the literal origin of the phrase "Keeping up with the Joneses." Though often referred to as a "Mystery Mansion" by urban explorers, this is the ruin of Wyndcliffe, the estate of Elizabeth Schermerhorn Jones.

Elizabeth’s mansion was so grand and intimidating that it prompted her neighbors—including the Astors—to build even larger homes to compete. The secret of Wyndcliffe is the psychological impact of its architecture; it was built to inspire envy, and its current state of absolute decay is a poetic commentary on the fleeting nature of social status.
