King Kong (1933)

Do you remember the famous scene atop the Empire State Building, where a giant ape defends his beloved Ann Darrow from attacking biplanes? How could anyone forget! King Kong , which debuted as early as 1933, was created using stop-motion animation, combined with rear projection and miniatures. Kong is portrayed as both a destructive force and a sympathetic character. The film became one of the most influential monster movies in American cinema and led to multiple remakes and spin-offs over the decades.

Dracula ( Bram Stoker’s Dracula , 1992)

Francis Ford Coppola’s cinematic rendition of the famous vampire was released in 1992 and relied heavily on practical effects and elaborate costumes. Gary Oldman’s Dracula appears in several distinct visual forms, including an elderly nobleman and a younger, more polished figure. The film openly references earlier screen versions, particularly Bela Lugosi’s 1931 performance, which established the cape, accent, and formal demeanor that many Americans still associate with the character.

3

The Rancor ( Return of the Jedi , 1983)

The Rancor, a massive reptilian monster from the Star Wars universe, first appeared in Return of the Jedi in 1983. The creature, brought to life using stop-motion animation, is known for its powerful claws, sharp teeth, and intimidating roars, often kept as a dangerous pet or prisoner in pits by crime lords like Jabba the Hutt. Despite limited screen time, the Rancor became one of the most memorable monsters in the Star Wars saga.

4

The Xenomorph ( Alien , 1979)

The Xenomorph first appeared in Alien, the famous sci-fi horror film starring Sigourney Weaver and directed by Ridley Scott. Designed by artist H.R. Giger, the creature is instantly recognizable by its elongated head, inner jaw, and biomechanical body. The monster functions as a relentless, silent threat rather than a speaking villain. Its terrifying design became central to a long-running franchise that included sequels, toys, video games, and even theme park attractions.

5

Gill-man ( Creature from the Black Lagoon , 1954)

Introduced in 1954, the Gill-man is an amphibious humanoid living in the Amazon. The creature was brought to life using a full-body suit, with separate actors for land and underwater scenes. Its scaly body, webbed hands, and large, expressive eyes set it apart from other monsters of the era. The film was released during the 3D movie boom of the 1950s, which helped draw large audiences. If you’ve seen the film, we bet you’ve experienced a few chills!

6

Audrey II ( Little Shop of Horrors , 1986)

The sassy and manipulative Audrey II from Little Shop of Horrors is a large, carnivorous, talking plant created using puppetry and mechanical effects. Its design evolves throughout the film as it "grows," requiring multiple versions of the puppet to achieve each stage. The character’s unique mix of menace and comedy helped make it one of the most recognizable non-human monsters in American musical cinema.

7

Thing ( The Thing , 1982)

John Carpenter’s The Thing premiered in 1982, introducing a terrifying shape-shifting alien that can imitate people and animals, making it nearly impossible to identify. The creature’s look was created using extensive practical effects, including animatronics and prosthetics. Set in the icy isolation of Antarctica, the film became well known for using physical effects rather than computer graphics, a choice that helped it remain visually striking decades later.

8

Werewolf ( An American Werewolf in London , 1981)

John Landis’s An American Werewolf in London featured groundbreaking practical makeup effects. The unforgettable werewolf transformation scene, shown in full light rather than shadows, shocked audiences and became a milestone in cinematic creature design. The monster itself appears as a large, wolf-like creature with elongated limbs. Starring David Naughton and Griffin Dunne, the film combined horror and humor, helping it stand out among other monster movies of the era.

9

Yautja ( Predator , 1987)

The 1987 film Predator was groundbreaking in introducing a humanoid alien hunter equipped with advanced technology. Its tense combination of science fiction and high-stakes action captivated audiences of the late 1980s.

The creature is instantly recognizable by its dreadlocked head, mandibles, and thermal-vision mask. Known as Yautja, or Hish-qu-Ten, the Predator became a recurring figure in sequels, comics, and crossover films, cementing its place as one of cinema’s most iconic extraterrestrial monsters.

10

Nosferatu ( Nosferatu , 2024)

Released in 2024, Robert Eggers’ Nosferatu revisits the classic silent-era vampire tale with a darker, more historically grounded design. This time around, Count Orlok is shown as a decaying, human-looking figure rather than a romantic aristocrat, with pale skin, thinning hair, and period-accurate clothing. The film was shot largely in Eastern Europe, but aimed squarely at American audiences familiar with classic horror. Its approach highlighted mood and atmosphere over spectacle, connecting a 1920s character to modern horror sensibilities.

11

Graboids ( Tremors , 1990)

Graboids, the massive, worm-like predators with circular mouths lined with sharp teeth and tentacle-like tongues, were created using large mechanical props and practical effects. These underground creatures from Tremors have limited visibility and rely on vibrations, which adds a suspense element that appealed to mainstream audiences at the time. They were really scary, don’t you think?

12

Frankenstein’s Monster ( Frankenstein , 2025)

This modern version of Frankenstein revisits the classic monster first popularized in the U.S. by the 1931 film. In keeping with the preconceived image that many viewers have, the monster retains its stitched skin, heavy movements, and a silent presence. Although it is the most recent film on our list, the creature’s appearance and physicality lean heavily on practical makeup and prosthetics rather than on computer-generated visual effects, reflecting Guillermo del Toro’s preference for tactile, artisanal creature design. Thanks to his decision, the character remains a figure shaped by human actions rather than a simple villain.

What are bills made of?

Unlike other currencies, dollar bills are not made of paper or plastic. U.S. dollar bills are made from a special fabric blend composed of 75% cotton and 25% linen. This mix makes the bills extremely durable and resistant, and they can be folded about 4000 times before tearing.

2

What bills are valid?

Any U.S. dollar bill that was legally printed is valid, no matter how old, as American currency does not have an expiration date. While some bills might not be accepted by businesses of foreign exchange services due to their condition or if they are a discontinued version of the bill, the bills themselves are still valid, and American banks will accept them, though they might take them out of circulation.

3

American leaders

Five bills have a depiction of an American president. The exceptions are the $10 bill, with Alexander Hamilton on the front, and the $100 bill, with Benjamin Franklin. The $1 bill, depicting George Washington, is extremely symbolic: several elements are repeated 13 times as a nod to the thirteen colonies, and it showcases the Bald Eagle and the Eye of Providence as a sign of God watching over America.

4

A change in size

Did you know that dollar bills used to be so big that they were nicknamed "horse blankets"? Original dollar bills were 7.4 × 3.1 inches. In 1929, the Treasury Department reduced the size of bills to 6.14 × 2.61 inches to reduce production costs and materials. Old bills, though still valid, are worth much more as collector items.

5

Uniformity

Besides their value and design, all dollar bills have the same size (6.14 × 2.61 inches), color, and weight (1 gram) , which sets American currency apart from other countries where bills of different values are differentiated by size, color, or both. Why doesn’t the U.S. implement differences among bills? The cost of adapting vending machines, bank drawers, and ATMs to new bill sizes would cost billions of dollars.

6

Hard to copy

Originally, dollars were not green, but black. As time passed, green ink was favored, as it was cheap and did not fade as much as black. The new color also prevented people from using black-and-white cameras to create counterfeit money. Currently, dollar bills are predominantly green, but newer versions also include extra colors, such as pink, orange, or purple.

7

A $100,000 bill?

Have you ever seen a $500 or 1,000 dollar bill? What about a $100,000? Up until 1945, the U.S. Treasury printed $500, $1,000, $5,000, $10,000, and $100,000 notes , in addition to the values currently in use. These higher-value notes were mainly intended for bank and government use, but were sought by criminals as they made it easier to hide large amounts of money. Even though they were officially discontinued in 1969, these notes are still valid, though rare, and they have a high worth as collector's items.

8

No numbers

Unlike bills, American coins have different sizes and colors related to their value. Originally, gold, silver, and copper were used for coins, but modern coins are made of copper, zinc, or nickel. Besides their size and design, the value of each coin is printed in letters, not in numbers , alongside depictions of American presidents.

9

Liberty for all (the coins)

By law, all American coins must include six specific details : the word ‘Liberty’, the name of our country, the national motto "In God We Trust", the oldest American motto "E Pluribus Unum", the value of the coin, and the year. Each coin also includes a mint mark that shows where it was made: "P" for Philadelphia, "D" for Denver, "S" for San Francisco, and "W" for West Point.

10

A global currency

The American dollar is one of the most powerful currencies in the world, acting as a backbone for international trade and finances. It is estimated that two-thirds of the physical dollars in circulation are outside American territory. Besides the U.S. and its territories, eight sovereign nations have the U.S. dollar as their official currency, with several more accepting it as legal tender.

There's an unexplained billion-year gap

Look closely at the canyon walls, and you'll notice something strange: a clean, sharp line where ancient rock simply stops, and a much younger layer begins directly above it.

This geological puzzle is called the "Great Unconformity," and it represents over a billion years of rock layers that are simply absent , as though that stretch of time never happened. In some spots, rock dated 1.8 billion years old sits directly beneath rock that is only 520 million years old. Where did the missing billion years go?

The leading theory involves the violent breakup of an ancient supercontinent, but scientists are still piecing it together.

During the Cold War, it hid a nuclear fallout shelter

During the Cuban Missile Crisis in 1962, the U.S. government converted part of the Grand Canyon Caverns into a fallout shelter. This dry cave system, more than 200 feet underground, was stocked with enough food and water to sustain 2,000 people. Naturally, it was never occupied, and the supplies were never used.

The caverns have since been transformed into a tourist attraction, with organized tours winding through the same underground chambers that were once intended as a refuge from nuclear war. You can even book a night's stay there.

The Federal Aviation Administration was founded after a crash over the canyon

In 1956, two commercial passenger planes collided in midair over the eastern Grand Canyon, killing all 128 people on board both crafts. Rescue teams struggled to reach the wreckage deep inside the canyon, and the extreme heat of the crash had caused the planes' aluminum to fuse with the bedrock. There were no survivors.

The disaster exposed a terrifying truth: the U.S. air traffic control system was dangerously outdated, relying on pilots' visual estimates and rough guesswork from controllers , with no way to separate fast-moving aircraft from slow ones, or instrument-flying planes from those navigating by sight. Congress responded by passing legislation that created both the Federal Aviation Administration (FAA) and the National Transportation Safety Board.

4

A hoax suggested that an Egyptian civilization had lived there

In 1909, the Arizona Gazette reported that an explorer named G. E. Kinkaid had discovered a vast underground citadel inside the canyon, filled with artifacts linked to ancient Egyptian civilization. He even claimed the expedition had been funded by the Smithsonian.

This story described hieroglyphics on the walls, mummies in the chambers, and relics pointing to a direct connection with the Egypt of the pharaohs. It was incredibly detailed, and it was, of course, a hoax. No evidence for any of Kinkaid's claims ever surfaced.

5

Fewer than 100 people have ever hiked its full length

Among the few people who have completed the through-hike of the Grand Canyon is Jen Hogan, the first woman to accomplish it, finishing her journey in 2021–2022.

It’s a full 800-mile length below the rim. The route involves extreme heat, flash floods, near-impassable areas, and stretches with no water or trail whatsoever. Around 60 or 70 people have reportedly accomplished it. This makes it one of the most exclusive feats on Earth.

6

The Grand Canyon's rocks predate dinosaurs entirely

Visitors scanning the canyon walls for fossils are often surprised to learn they won't find any dinosaur bones here. The rock layers of the Grand Canyon are simply older than dinosaurs. This fact alone can be shocking: staring at its walls means staring at marine fossils from as far back as 1.2 billion years ago. Some of its caves hold the remains of ancient mammals. The canyon is a window into a world that existed long before the dinosaurs, when the land that is now Arizona lay beneath a shallow sea.

7

The park is bigger than Rhode Island

Numbers alone rarely capture the Grand Canyon's scale, so here's a different approach. Rhode Island covers about 1,214 square miles, and the Grand Canyon National Park spans 1,904 square miles.

The canyon's depth exceeds four Empire State Buildings (which is 1,454 feet) stacked on top of one another. That’s 6,093 feet at its deepest point.

8

But it's not the deepest canyon on Earth

For all its grandeur, the Grand Canyon does not hold the depth record. Pictured above, the Yarlung Tsangpo Grand Canyon in Tibet, China, plunges to 17,567 feet, which is nearly three times deeper. Carved by the Yarlung Tsangpo River as it cuts through the eastern Himalayas, that canyon is so remote and extreme that it remained largely uncharted until the late 20th century.

9

It is home to a pink rattlesnake found nowhere else on Earth

The Grand Canyon Pink Rattlesnake has a pinkish-red coloring that matches the canyon's own distinctive rock walls so closely that it's nearly invisible. It is found nowhere else in the world. Officially classified as Crotalus oreganus abyssus , it has darker diamond-shaped markings along its back that deepen the camouflage further.

10

There's a village at the bottom: Supai Village

For over 1,000 years, the remote village of Supai has been home to the Havasupai Tribe, the People of the Blue-Green Waters. It is located an eight-mile hike from the rim, but sits roughly 3,000 feet deep inside the Grand Canyon.

The U.S. Department of Agriculture has called it the most remote community in the contiguous United States, and it has no automobiles and no road access. The only ways in are on foot, by mule, or by helicopter. It is also the only place in the United States where the postal service still delivers mail by mule train.
