It is no secret: Jack Nicholson is one of the most talented actors of all time, and the evidence is everywhere you look.

A big piece of evidence is the fact that one of the most famous lines in movie history came from his brilliant mind. The mythical "Here's Johnny!" from The Shining (1980) was entirely crafted by Nicholson as it wasn't found in the film's script or Stephen King's original book.

Yet, the actor's creativity, coupled with Kubrick's directing expertise, transformed that scene into an emblem of horror cinema.

Who could ever forget the legendary shark from Jaws (1975)? With its huge mouth and sharp teeth, it frightened even the bravest spirits. So, when faced with the movie's formidable sea monster, actor Roy Scheider couldn't help delivering this creative line.

"You're gonna need a bigger boat," as later revealed, was a line used as an inside joke by the cast and crew, as the boats on which they did the actual filming were quite small. Thus, Scheider took the phrase and perfectly placed it within the film, even though it wasn't originally scripted.

If you are reading this article, chances are you've watched the masterpiece Casablanca (1942). And you probably know that one of its countless iconic lines was a spontaneous creation of the talented Humphrey Bogart.

The well-remembered line "Here's looking at you, kid" came out of Bogart's mouth and perfectly fit the moment. It worked so well that it was named the greatest-ever movie line by Premiere Magazine.

But here's a fact: the movie's script was not yet finished when filming began.

While the famous lineup scene in The Usual Suspects (1995) was in the script, the actors’ fits of laughter were completely improvised. Or should we say, impossible to hold back!

As revealed by the film's screenwriter, Christopher McQuarrie, it was a small accident that caused laughter among the actors: let's just say one of them accidentally let out... a gas.

However, that spontaneous moment added a touch to the scene, and that shot ended up making the final cut.

Have you ever taken a cruise? If you're on the bow, your hair in the wind, you probably can't resist the impulse to imitate Leonardo DiCaprio, delivering that iconic line from the now classic Titanic (1997).

But, if it weren't for the actor's genius, the famous "I'm the king of the world!" would not have reached us, as it was not in the movie's script!

Sure, standing in front of the vast ocean may make you feel all-powerful, but DiCaprio's brilliance took it a step further and made up those lines while filming in a studio setting!

Leonardo DiCaprio's talent for improvisation isn't just a thing of one time. From Titanic when he was just a twenty-something, to his more mature roles in films like the western Django Unchained (2012), Leo's talent always shines.

In Django, DiCaprio once again showed his acting skills, moving through unexpected turns like a champion.

During a passionate monologue, Leonardo DiCaprio's character slams his hand down on a table, and he actually cuts himself. Blood begins to dribble, but he incorporates the accident into the scene, as part of the plot. That's a mark of true talent!

From The Simpsons to Scary Movie, numerous series and films have quoted this iconic line from A Few Good Men (1992) that has become a pop culture hit!

But if it weren't for Jack Nicholson in his performance as Colonel Nathan R. Jessup, this memorable phrase from the famous courtroom scene wouldn't have had the same impact or recognition that it has today.

The actor took a simple line from the script, "You already have the truth," and transformed it into the legendary, "You can't handle the truth." It's proof of Nicholson's genius!

A gem of American cinema, Midnight Cowboy (1969) is a perfectly crafted masterpiece acclaimed by critics and audiences alike.

But even in this great classic, there's room for spontaneity. In fact, one of the most memorable moments in the movie wasn't even in the script. While playing the con man Ratso Rizzo, Dustin Hoffman found himself in the middle of real New York City traffic during filming. When a taxi unexpectedly went too close, Hoffman's instinctive response was perfect: "Hey! I'm walking here."

Leonardo is back once again. This time, joined by the incredible Matthew McConaughey. Together, they delivered one of the best moments of 21st-century film history: the unforgettable chest-pounding scene in The Wolf of Wall Street (2013).

Turns out this bizarre gesture is something McConaughey often does before filming his scenes. But it was Leonardo DiCaprio who saw this spontaneous act and suggested incorporating it into the film's well-known scene. The eccentric nature of the characters allowed for this twist, which was accepted and appreciated by the director.

But wait, there's more! Believe it or not, part of the dialogue between the two characters was also unscripted.

Martin Scorsese, the successful director, revealed that one of the most famous lines in Taxi Driver (1976) and why not, in world cinema, was improvised by Robert De Niro.

The iconic "You talkin' to me?" monologue was not in the script; it was a spontaneous creation of the actor during the filming of the exceptional mirror scene. It's the small details like these that make Taxi Driver a true classic and Travis Bickle an unforgettable character.

Naturally, this role made De Niro earn an Oscar nomination for Best Actor.

Body oddities

You have bugs in your face and bones full of holes—12 creepy body facts

The human body is a marvel of biology—but sometimes, it's downright disturbing. Did you know it’s possible to cry blood? Or that we have taste receptors in our stomachs? From mysterious functions to deeply unsettling facts, our bodies are full of creepy surprises hiding beneath the surface. Here are 12 weird but true insights into what’s really going on inside you.

Unlike most body parts, ears (and noses) continue to grow as you age. It’s not just cartilage at work—gravity slowly stretches skin and tissue, making ears longer over time.

This process, sometimes called "gravity-induced elongation," only starts to become more noticeable after age 30. That’s why elderly people often seem to have larger ears, even if they were proportionate in youth.

Receptors similar to those on your tongue exist in your stomach and intestines. They don’t "taste" in the traditional sense, though, but detect chemical signals.

Thanks to these oddly placed "taste" receptors, our bodies help regulate digestion and appetite by detecting nutrients and potential toxins. They’re crucial for gut-brain communication and may even influence cravings.

Yes, you read that right. Your eyelashes are home to Demodex mites—tiny, spider-like creatures that feed on dead skin cells and oils around hair follicles.

It may sound like something out of a horror movie, but most people—especially adults—have them. These mites emerge at night, mate on your eyelids, and retreat by morning. They’re harmless, but still undeniably creepy.

Your body emits a small amount of radiation due to naturally occurring elements like potassium-40 and carbon-14, which are present in body tissues.

While this natural radioactivity is harmless, it’s still measurable. A single human body can emit around 7,000 particles per second—enough to trigger some sensitive detectors.

Called haemolacria, it’s a rare condition where blood mixes with tears. Its causes can include infections, injuries, tumors, or hormonal changes.

Though quite dramatic and certainly alarming, some cases are benign. It has been documented in both adults and children, and it is often linked to extreme stress.

Even just walking through a room, you leave behind a cloud of genetic material—skin cells, saliva, and sweat—all rich in your DNA.

Sometimes called a "biological fingerprint," this material is enough to identify you. Law enforcement and forensic scientists can even recover DNA from air filters or dust!

Some people are born with supernumerary organs—extra kidneys, spleens, or even, in extremely rare cases, hearts. These additional organs are often non-functional but can still be detected.

For example, an estimated 1 in 1,000 people has an extra spleen, often discovered by accident during unrelated scans or surgery.

Lack of sleep triggers glial cells in the brain to break down and consume parts of synapses—literally "cleaning house" in an extreme way.

This self-cannibalization can lead to cognitive decline and has been linked to neurodegenerative diseases in chronic cases.

Osteomas are benign bone tumors that can sometimes protrude through the skin, resembling small "horns." Most appear on the skull or jaw.

Though rare, some osteomas can grow several inches. Surgical removal is usually performed for cosmetic reasons unless the growth interferes with normal function.

The human mouth can harbor over 700 different types of bacteria—many more than you'd find on a toilet seat.

Most of these bacteria are harmless—and even essential for healthy bodily functions—but under poor hygiene or illness, they can cause infections, tooth decay, or even contribute to heart disease if they enter the bloodstream.

In extremely rare cases, a type of tumor called a teratoma can develop in the lungs and contain hair, teeth, or even eye-like tissue.

Teratomas are usually benign but still quite bizarre. They form from germ cells and can grow almost any tissue type due to their stem cell origin.

Even the hardest bones in your body are porous like a sponge. Under a microscope, they reveal a honeycomb structure filled with blood vessels and bone marrow.

This structure makes bones both strong and lightweight. However, in conditions like osteoporosis, those holes widen, weakening the bone from the inside.
