X-Men (2000)

Remember the scene when Magneto and Professor X play a tense, symbolic game of chess? Well, the actors certainly do. Here’s why: Neither Patrick Stewart nor Ian McKellen knew how to play chess before filming.

So, director Bryan Singer brought in a Canadian chess Grandmaster to help design the game the two men would share by choreographing each piece's movement based on the high-strung dialogue they were having —Professor X needed to win.

E.T. the Extra-Terrestrial (1982)

Did you know that E.T., the beloved extraterrestrial who wanted to phone home, was intentionally designed to have no specified gender ?

Director Steven Spielberg expressed that his intention was to define E.T. as a "plant-like" creature, neither male nor female, and that this was explicitly explained in earlier versions of the script.

However, in the film, young Elliott insists that he knows the gender of his newfound friend: "He’s a boy," he explains to his sister when she asks. The audience went along with Elliott’s interpretation, and hence E.T. is considered to be male.

How the Grinch Stole Christmas (2000)

Jim Carrey loathed the process of becoming The Grinch. Though the Dr. Seuss character was fun to play, sitting for hours and hours for makeup and costume until the green look was perfected, he said, was exhausting.

So, he was shocked one day when he arrived on set, only to find yet another Grinch ready there before him. It was none other than director Ron Howard, who had been up since 3:30 am, getting into full costume in solidarity with him.

The Nightmare Before Christmas (1993)

Watching Tim Burton’s The Nightmare Before Christmas, one might take for granted that the stop-motion marvel took years of painstaking effort. Around 227 puppets were built for the production because each character had multiple duplicates to allow shooting on many sets simultaneously.

The protagonist Jack Skellington alone needed nearly 400 different heads to capture enough facial expressions.

5

Toy Story (1995)

Even though we all recognize Woody the Cowboy, there was a time when the leading character of Toy Story was going to be… quite different.

Sheriff Woody was at first conceived as a ventriloquist dummy . But the Pixar creators thought that a softer cowboy toy would be a little bit friendlier. What do you think?

6

Star Wars: A New Hope (1977)

We all know the loyal little robot of the Star Wars world. But R2-D2’s name came about unintentionally. While filming a previous film, George Lucas had liked an abbreviation he heard his sound editor shout one day: "R2, D2".

It referred to "Reel 2, Dialogue Track 2" . But the expression sparked Lucas’s imagination.

7

Home Alone (1990)

Yes, Kevin is nine years old in the movie. But most of his "dangerous" moments were handled by a 30-year-old stuntman in kid-sized clothes!

Still, some injuries were inevitable. And they didn’t come from hanging from a zipline or sliding downstairs: No, young Macauley Culkin got a scar from Joe Pesci accidentally biting his fingers too hard in one scene.

8

Interstellar (2014)

Christopher Nolan’s Interstellar is well known for its ambitious science fiction vision. But Nolan went above and beyond with details. For example, the robot TARS wasn’t a CGI creation: it was physically built (a kind of "puppet-robot").

Plus, the space suits the actors wore were designed with functioning oxygen units and cooling tubes! Needless to say, though, all scenes were filmed on Earth.

9

The Matrix (1999)

Did you know that Johnny Depp was the first choice to play Neo for The Matrix ? As an up-and-coming actor in the 90s, the writers had considered him perfect for the role. However, fate decided Keanu Reeves would take the part, and the rest was history.

Reeves didn’t have it easy, though: the Wachowskis had him read philosophical books like Simulacra and Simulation by Jean Baudrillard, Out of Control by Kevin Kelly, and Introducing Evolutionary Psychology by Dylan Evans.

Scarface (1983)

After Martin Scorsese saw Brian De Palma’s Scarface, he reportedly told actor Steven Bauer: "It’s great… but they’re going to hate it ."

He wasn’t wrong. Critics did hate it, at first. They called it vulgar, excessive, hysterical, and violent. Scorsese himself had been criticized for the violence in his own work, so he recognized the pattern instantly. However, as we know, audiences eventually made it a cult classic.

Network executives thought Desi Arnaz was "too foreign" for TV

Network executives initially hesitated to cast Desi Arnaz as Ricky Ricardo, Lucille Ball’s husband on I Love Lucy (which aired on CBS from 1951 to 1957) because they doubted that viewers would accept an American woman and a Cuban man as a believable suburban pair.

To prove the concept worked, Ball and Arnaz took a live vaudeville act on the road in 1951, receiving overwhelmingly positive feedback from audiences. The public's reaction helped persuade CBS to give the show a chance with Arnaz in the starring role. And as we all know, the couple was married in real life too and eventually had two children: Lucie, born in 1951, and Desi Jr., born in 1953. It doesn’t get more "real" than that.

2

The word "pregnant" was strictly forbidden on air

On the show, CBS banned the word "pregnant" in 1952, considering it too explicit for family living rooms . Writers therefore relied on euphemisms such as "expecting," "with child," or "having a baby."

When Lucille Ball became pregnant with her second child in 1952, Desi Arnaz pushed for her pregnancy to be written into the show's storyline, despite initial resistance from CBS and its sponsors. The resulting plot became a landmark moment in television history: although the show could portray Lucy expecting a baby, its writers still couldn't use the forbidden word. That’s why the episode in which she breaks the news to Ricky was titled "Lucy Is Enceinte," using the French word for pregnant.

More people watched Lucy give birth than the president’s inauguration

On January 19, 1953, the episode "Lucy Goes to the Hospital", in which she gives birth to Little Ricky, drew an estimated 44 million viewers (about 72% of U.S. television households). In an extraordinary coincidence, Ball gave birth to her real-life son, Desi Arnaz Jr., by scheduled cesarean section on the same day.

The next day, President Dwight D. Eisenhower’s inaugural address drew an estimated 29 million viewers. That means the episode attracted roughly 15 million more viewers than the president's address, according to the commonly cited estimates.

The candy factory episode had a real-life expert in it

In the beloved "Job Switching" episode, the Season 2 premiere which aired on September 15, 1952, Lucy and Ethel (Vivian Vance) take jobs at Kramer’s Kandy Kitchen to prove to their husbands, Ricky and Fred (William Frawley), that they can handle the demands of working outside the home.

Assigned to wrap and dip chocolates on an assembly line, the pair fall hopelessly behind as the conveyor belt speeds up. Desperate to avoid letting any unwrapped candy pass by, they begin stuffing chocolates into their mouths, hats, and blouses. The resulting chaos became one of television's most beloved comedy scenes. But here's a fun backstage detail: to prepare for the sequence, Ball and Vance spent half a day learning to dip chocolates and work on the production line at a real See's Candies location in Los Angeles. Even more interesting, the woman working alongside Lucy in the scene was an actual See's Candies candy maker, Hazel Pierce .

5

Fred and Ethel viscerally despised each other in real life

Playing married couple Fred and Ethel onscreen, Frawley and Vance clashed throughout the show's six-season run. Vance was 42 and Frawley was 64 when the show started. She reportedly resented being cast opposite a man 22 years older and famously complained: "How will anyone believe I’m married to that old man?" Frawley overheard her complaints and was reportedly offended. He later made this pointed remark about Vance, "She's one of the finest girls to come out of Kansas, but I often wish she'd go back there."

Despite their bitter off-screen feud, both remained professional on set and delivered the comedic chemistry that made Fred and Ethel such a memorable couple. Vance later reportedly turned down a lucrative spin-off featuring the pair, along with a $50,000 bonus, because she didn't want to work with Frawley again.

Desi Arnaz’s deal that changed TV reruns forever

Desi Arnaz’s production decisions helped establish reruns as a profitable part of the industry. He insisted that I Love Lucy be filmed rather than broadcast live, helping shape the modern sitcom format. In the early 1950s, television shows were preserved only as low-quality kinescopes, recordings made by filming television screens.

Ball and Arnaz wanted high-quality recordings, so they were shot on 35mm film using a three-camera setup in front of a live studio audience. As part of their landmark deal with CBS, their production company, Desilu Productions, retained ownership of the film negatives, allowing the episodes to be rebroadcast. By 1955, I Love Lucy had become the first television series to be broadcast as reruns , helping pave the way for modern syndication.

7

Ricky Ricardo was almost named "Larry Lopez"

During the development of I Love Lucy, Ricky Ricardo was initially called Larry Lopez, but the name was changed for two main reasons.

First, the producers wanted to avoid confusion with Vincent Lopez, a well-known bandleader of the era. Second, they reportedly preferred the sound of "Lucy and Ricky" to "Lucy and Larry," since it sounded overly alliterative.

Lucy was not a natural redhead

Lucille Ball wasn't a natural redhead. Instead, she was a brunette who kept her brown hair during her early career, and also experimented with blonde shades before adopting the fiery red look that became her trademark.

Around 1943, she famously went red for her role in the Technicolor musical Du Barry Was a Lady. MGM hairstylist Sydney Guilaroff helped create the look , which Ball later maintained with a custom blend of henna and dye. Ultimately, her signature color was a carefully crafted Hollywood style, not her natural shade. And it worked.

Desi Arnaz used cushions to appear taller than Lucy

Desi Arnaz reportedly wore Cuban heels or other elevated footwear to help him appear taller alongside Lucille Ball. Although he stood around 5 feet 9 inches tall and Ball about 5 feet 7 inches in her stocking feet, her high heels could make her look taller than him.

The production team reportedly used another trick when the couple sat down : specially arranged cushions on the Ricardos’ couch and chairs helped maintain the desired height difference on screen and made it easier for Arnaz to stand up.

10

Lucy’s mother left her mark on the show’s soundtrack

Lucille Ball's mother, DeDe Ball, was a devoted supporter who reportedly attended the filming of almost every episode. Whenever her daughter landed in a comically awkward situation, DeDe would let out a distinctive "Uh-oh!" from her seat in the studio audience.

Sound engineer Glen Glenn reportedly liked the exclamation so much that he recorded it and incorporated it into the show's laughter track . Because the same recording was reused, DeDe's distinctive voice became part of the show's familiar soundtrack. The story even suggests that her "Uh-oh!" may have made its way into the soundtracks of other classic sitcoms over the years.

Swim fins

If you don’t know who invented swim fins, this one might startle you! Before he was flying kites in thunderstorms, Benjamin Franklin was just an 11-year-old boy who loved to swim.

He invented early swim fins, but not the kind we wear on our feet. He designed wooden paddles with thumb holes that could be held in the hands to help propel a swimmer through the water faster. He also tried strapping fins to his feet, but found them less effective and even painful.

Popsicles

The brand Popsicle tells the legendary story: eleven-year-old Frank Epperson left his soda drink with a stirring stick on the porch overnight. When he returned the next morning, he discovered a brilliant idea— frozen juice on a stick !

Originally named the "Epsicle" (after himself), the invention was patented in the 1920s. His children called them "Pop’s ’sicles," and the name Popsicle stuck.

Earmuffs

Chester Greenwood couldn’t endure Maine winters. At 15 years old, his ears got cold, and he didn’t like the feeling of wool hats on his skin. So he devised a creative solution: his grandmother sewed beaver fur onto a wire headband that he shaped into circular ear loops.

That invention was later patented in the 1870s, becoming the world’s first earmuffs, according to historical records.

Toy trucks

Using bottle caps, cardboard, and ingenuity, Robert W. Patch created a toy truck that could transform into multiple styles: a dump truck, flatbed, or box truck. And he was only 5 years old.

The modular vehicle concept was so compelling that his father, who happened to be a patent attorney, filed for official recognition. By the time Patch turned six, he had been granted a U.S. patent, making him one of the youngest inventors in history.

Superman

Jerry Siegel and artist Joe Shuster were both high school students when they came up with the idea for the Man of Steel in 1933.

They created Superman as the ultimate underdog: an alien orphan who fights for justice. The character was sold to Action Comics in 1938, launching the entire superhero genre.

Hot seat

A heartbreaking story of a baby dying after being left inside a hot car reached Bishop Curry V when he was 10 years old.

This inspired him to design a device he called Oasis (often referred to in the media as the "Hot Seat"). His invention detects rising temperatures in a car, blows cool air, and alerts parents and emergency services.

Water skis

Ralph Samuelson was a teenager when he had an idea: if people could ski on snow, why not on water? In the early 1920s, he took two pine staves , curved the tips using boiling water , and hit the lake with his brother, towing him behind a motorboat.

After many belly flops, he figured out the proper posture and became the first water skier in history. Although he never patented his creation, he spent years performing and became known as the "Father of Water Skiing."

Trampolines

Who knew? George Nissen was just 16 when he devised the bouncy fun. In the early 1930s, he watched circus trapeze artists drop and land into safety nets and realized: what if you could bounce back ?

Working out of his parents’ garage, he stretched canvas across a frame and added springs. Initially, trampolines were used for gymnastics training, but even NASA later adopted them to train astronauts.

Makin’ Bacon

Michigan native Abbey Fleck did not invent bacon itself, but at 8 years old, she had grown tired of soggy bacon and paper towels. She brainstormed a simpler solution: hang the bacon while it cooked, allowing grease to drip away cleanly.

Together with her dad, she built a prototype in the 1990s and earned a U.S. patent for the microwavable "Makin’ Bacon" tray. It became a retail hit .

Wristies

Cold, wet sleeves are a winter misery. 10-year-old Kathryn Gregory grew frustrated with snow slipping between her mittens and coat sleeves, so she sewed together a pair of warm fleece tubes to cover the gap between glove and sleeve .

She called them Wristies. Her invention was such a hit with friends and family that her Girl Scout troop encouraged her to patent it—and she did! Kathryn became one of the youngest inventors to receive a U.S. patent.

Crayon holders

Ever struggled to hold a crayon that’s worn down to a stub? So did 11-year-old Cassidy Goldstein. She noticed how frustrating tiny crayons could be, especially for kids just learning to grip.

She came up with a simple solution: a plastic cylinder that could hold broken or short crayons , making them easier to use. Patenting the design earned Cassidy the Youth Inventor of the Year Award.
