Movies are forever. Movie scripts, on the other hand, are hardly set in stone. Throughout the history of cinema, some of the best, most iconic lines that ever existed were created on the spot, delivered accidentally, or made up by the inventive minds of Hollywood actors.

There’s no shortage of iconic improvised lines in this compilation, from Orson Welles’ The Third Man to Walt Disney’s Frozen! And some of these are so good, clever, and memorable that it’s almost unbelievable to think they were never part of plan A. Has your favorite film made it to the list?

"You Can't Handle the Truth!" (A Few Good Men)

With Jack Nicholson, Tom Cruise, and Demi Moore in the leading roles and Aaron Sorkin as the screenwriter, the 1992 drama A Few Good Men was bound to be good. The movie did make a huge impact, but it’s still hard to believe that one of the best lines in the entire film was made up on the spot by Nicholson.

The script read: “I want the truth!” but Nicholson wasn’t a big fan of the line. So he changed it a little bit, coming up with the more impactful “You can’t handle the truth!” It fitted perfectly within the plot and Nicholson’s character, the self-entitled Colonel Nathan R. Jessup.

"She Talks in Her Sleep" (Indiana Jones and the Last Crusade)

In the late ’80s, Indiana Jones movies were the finest example of an adventure/action blockbuster series. But when the producers decided to add Sean Connery to the mix (cast as Jones’s father), the 1989 classic Indiana Jones and the Last Crusade gained a whole new momentum.

But who could’ve guessed that one of Connery’s most memorable lines was unscripted? When asked about how he knew Elsa Schneider was a Nazi, he replied by saying, “She talks in her sleep.” The line was received with an all-too-honest smile by Harrison Ford, who wasn’t ready for the off-script moment, and a big thumbs up from director Steven Spielberg, who loved it instantly.

"I'm Walkin' Here!" (Midnight Cowboy)

The 1969 drama Midnight Cowboy is an ever-lasting cinema classic and features one of the best performances in Dustin Hoffman’s career. His masterful, angry line “I’m walkin’ here!” (directed towards a taxi driver) fits perfectly within the style of his character Ratso. Of course, it was improvised.

Hoffman and co-star Jon Voight were crossing the street when they nearly got hit by a real cab. Most actors would stop filming immediately, but not Hoffman. He was so comfortable as Ratso that he came up with the perfect, Ratso-like reaction right there and then. And that’s how how “I’m walkin’ here!” became one of the best-known movie quotes ever.

"I Know" (Star Wars: Episode V - The Empire Strikes Back)

When someone you love says “I love you,” the polite answer is to say “I love you” back. But that doesn’t sound like Han Solo at all, does it? Solo was a kind yet stubborn and proudful man, and Harrison Ford felt like his scripted reaction to Leia’s confession of love was just not right.

The original line was a dull “I love you too,” so Ford asked George Lucas if he could change it. Ford then came up with a perfect improvised line that was both hilarious and fitting of Solo’s character: “I know,” making for one of the most memorable and endearing moments in the Star Wars saga.

"Hey Malkovich, Think Fast!" (Being John Malkovich)

Being John Malkovich is a fairly weird movie about a man who discovers a portal that allows him to literally get inside John Malkovich’s head. In one of the most memorable scenes in the film, Malkovich is walking down the street when he hears “Hey Malkovich, think fast!” and gets violently hit by a can.

The unscripted moment made it to the movie because it was good cinema! It was nothing but the work of a drunken extra, though, who wanted to make an impact. Instead of being fired, the man received an acting credit. After all, he was “given” one of the most memorable lines in the film.

"I Don't Care" (The Fugitive)

The Fugitive was a great early ’90s movie. It depicted a cat-and-mouse chase between an innocent man accused of murdering his wife, played by Harrison Ford, and the U.S. Marshal tasked with putting him in jail, played by Tommy Lee Jones.

When the two rivals finally stumble upon one another in a tunnel chase scene, Ford’s character appeals to Jones by saying, “I didn’t kill my wife!” Jones was supposed to answer with, “That’s not my problem,” but he decided to change the script just a little bit... He went for “I don’t care,” and the improvised line resonated perfectly with his character’s blind respect for rules over justice.

"Funny How? I Amuse You?" (Goodfellas)

While director Martin Scorsese gets most of the credit for his mobster classic Goodfellas, he needs to thank actors Joe Pesci and Ray Liotta for one of the movie’s most memorable scenes. Remember when Pesci’s character loses it at the restaurant after being called funny?

As it turns out, the moment was crafted off-camera by Pesci and Liotta and only added later to the script. The remarkable scene showed Pesci’s out-of-control character overreacting to an innocent comment made by one of his friends, who decided to call him funny. The whole situation escalated beautifully into a full-blown conflict and has remained one of Goodfellas’ most iconic moments.

"You Talkin' to Me?" (Taxi Driver)

If you don’t enjoy Robert De Niro’s brilliant performance in Taxi Driver, do you even like cinema? De Niro was perfect in the role of the psychopathic Travis Bickle and delivered one of the best-known movie lines of all time: the much-quoted “You talkin’ to me?” that he delivered in front of the mirror.

But did you know De Niro’s now-iconic line wasn’t even scripted? In the original screenplay, the only instruction was “Bickle speaks to himself in the mirror,” and De Niro was given full creative control for the scene. The improvised lines were so good that we’re pretty convinced De Niro would make for a great screenwriter!

"You're Gonna Need a Bigger Boat" (Jaws)

Do you hate sharks? Well, you have the classic Steven Spielberg movie Jaws to thank for that! Jaws is filled with quotable lines, including the memorable “You’re gonna need a bigger boat.” But this particular sentence was actually unscripted and improvised, even though it made the rounds at the studio set.

It turns out the line was sort of a private joke amongst the crew, directed at the cheap producers who wouldn’t pay for a bigger boat to be featured in the movie. The line has somehow fitted wonderfully with Roy Scheider’s character, all while serving as a sarcastic burn to the producers.

"I'll Bet You Could Suck a Golf Ball Through a Garden Hose" (Full Metal Jacket)

Stanley Kubrick was an obsessive and hardworking director who left no detail to chance. And yet, he gave an unprecedented amount of freedom to the Full Metal Jacket actor R. Lee Ermey. Reportedly, over 50% of Ermey’s lines in the film were unscripted and improvised, including the now-iconic insult “I’ll bet you could suck a golf ball through a garden hose.”

There are many other remarkable Ermey lines in the movie, but we have to refrain from repeating most since he was a big fan of foul language. Released in 1987, Full Metal Jacket is still considered one of the best war-based films of all time.

"Leave the Gun. Take the Cannoli." (The Godfather)

Nothing screams “violence” like the scene where Peter Clemenza (Richard Castellano) decides to take a box of cannolis home with him in the presence of a murdered man. That’s what’s so impactful about The Godfather, though. The characters in the movie have such a casual relationship with violence it’s almost impossible not to feel shocked as a viewer.

But while the cannoli line resonates strongly with everything The Godfather is about, it was—you guessed it—improvised! The original line was just “leave the gun,” but Castellano decided to follow on a good piece of advice from his wife and get a little creative. Of course, director Francis Ford Coppola loved it!

Hannibal Lecter's Hiss (The Silence of the Lambs)

In The Silence of the Lambs, Anthony Hopkins delivered a masterful performance that helped to inspire the modern-day figure of the psychopathic serial killer. Hopkins stuck to the script most of the time, but one of the most remarkable aspects of his Hannibal Lecter portrayal was made up on the spot.

Remember the creepy hissing sound Lecter makes while Jodie Foster’s character is interviewing him? Well, that’s just Hopkins being Hopkins! The highly-inspired improv moment turned out to be one of the best in the whole film, allowing the viewers to see Lecter for what he truly is—a man so evil he can’t even be called a man.

"He Stole My Line" (Good Will Hunting)

The heartwarming Good Will Hunting film is mainly about the connection between the characters portrayed by the late Robin Williams and his co-star Matt Damon. The two actors had great on-screen chemistry, and it’s a pleasure to watch their father-son-like relationship develop throughout the movie.

In one of the most powerful scenes in the film, Williams reads a letter from Damon’s character while standing at the doorway. He was supposed to stay silent, but he ended up improvising one of the movie’s most memorable quotes: “He stole my line.” Reportedly, there were plenty of great unscripted moments in Good Will Hunting.

"People Call Me Forrest Gump" (Forrest Gump)

Forrest Gump is arguably one of the most-watched movies in America’s history, and its message of love and understanding is still extremely relevant today. But much of the film’s charm is due to Tom Hanks’ remarkable performance, which even included a now-iconic improvised line.

When Gump meets his good friend Bubba while joining the Army, Bubba introduces himself by saying, “People call me Bubba.” Gump was supposed to reply with a rather blunt “My name is Forrest Gump” but instead went with “People call me Forrest Gump,” which made the scene a lot funnier! The clever line fitted Gump’s personality like a glove.

"Like Tears in Rain" (Blade Runner)

You can’t call yourself a true sci-fi fan if you still haven’t watched Ridley Scott’s iconic 1982 masterpiece Blade Runner. In one of the film’s best scenes, the hero Rick Deckard (Harrison Ford) faces the main antagonist Roy Batty (Rutger Hauer).

In the scene, Hauer delivered a memorable speech, which included the quote, “All those moments will be lost in time, like tears in rain.” And while it sounded like something the Blade Runner screenwriters should’ve come up with, the actor made them up. Unsurprisingly, Hauer ended up working as a writer later in his career with the 2016 short movie Cuba Libre.

"Want to Hear the Most Annoying Sound in the World?" (Dumb and Dumber)

Improvised lines are pretty standard in comedy flicks, especially when you can count on people as talented as the one and only Jim Carrey. A genius comedic figure, Carrey was perfect in the role of the hilarious imbecile Lloyd from Dumb and Dumber.

In the 1994 movie, one of Carrey’s most famous improv lines happened when he asked Harry if he wanted to hear “the most annoying sound in the world.” In true Jim Carrey fashion, Lloyd delivered on his promise and made a poor hitchhiker feel utterly annoyed. In the scene, you can see Carrey briefly go off-character before delivering the unscripted line.

"...And I'm All Out of Bubblegum" (They Live)

In the John Carpenter anti-establishment classic They Live, a man finds a special pair of sunglasses that allow him to see the world’s true nature. He soon realizes that consumerism is meant to be obeyed and that society was taken over by thousands of aliens disguised as humans.

They Live is an unforgettable horror masterpiece, but curiously enough, the best-known line in the movie was created by the wrestler-turned-actor Roddy Piper, who was given complete creative control. You probably know how it goes: Piper enters a bank with a machine gun and says he’s all about chewing gum and killing aliens... and guess what? He’s “all out of bubblegum!”

"You Know... Morons." (Blazing Saddles)

In the 1974 comedy/western flick Blazing Saddles, Jim (Gene Wilder) tries to comfort Bart (Cleavon Little) when he complains that he’s still a victim of racism despite being a law enforcement officer. Jim tells him not to listen to the farmers, who he describes as the ignorant “common clay.”

But unbeknownst to everybody (especially the screenwriters), Wilder decided to end his line with a quite impactful “You know... morons.” This final sentence referring to the farmers wasn’t included in the script and was made up on the spot by Wilder, who often enjoyed improvising on the set and did so remarkably well.

"The Horror" (Apocalypse Now)

In 1979, director Francis Ford Coppola and iconic actor Marlon Brando got together to work on Apocalypse Now, which is still regarded as one of the best Vietnam War movies ever. But to Coppola’s surprise, Brando showed up with a little bit of extra weight, a physical feature that made no sense in the context of the film.

Coppola got around the issue using close-up shots for most of Brando’s scenes, hence concealing his plump body. But despite the difficulties, Brando’s contribution to the film was priceless. He improvised most of his lines, including the famous and exasperated “the horror,” whispered while lying on the ground.

"OK, Who Brought the Dog?" (Ghostbusters)

While actors Bill Murray, Dan Aykroyd, and Sigourney Weaver were the leading stars of the 1984 classic Ghostbusters, the crew’s main improviser was the hilarious Rick Moranis. He played the character of Louis Tully.

There’s a scene in Ghostbusters wherein Tully hosts a party for his clients, and Moranis extensively changed most of the lines on that scene. He modified the script and ad-libbed most of the lines, including the memorable “OK, who brought the dog?” It was a witty reference to the massive monster that crashed the entire party.

"I'm King of the World!" (Titanic)

Now this one’s a shocker! Pretty much everybody who’s seen Titanic has repeated the iconic DiCaprio line “I’m king of the world” in one moment or another. It’s just the perfect quote to describe a single moment of euphoria.

But surprisingly, the line was not part of the script and was made up on the spot by director James Cameron. He made it up almost instinctively and asked DiCaprio to “just sell it.” The young DiCaprio did his best, and what was the result? One of the most quoted, recognizable, and memorable lines in the history of cinema.

"Here’s Lookin’ at You, Kid" (Casablanca)

In the ’40s, show business was a bit different. While filming the classic movie Casablanca, the screenwriters were also still working on the actors’ lines. Much of the script was written in a hurry, which is almost unbelievable considering the quality of the dialogue.

While there were certain downsides to this, one of the pluses was that the actors were given freedom and were allowed to ad-lib whenever they felt necessary. That was exactly what Humphrey Bogart did when he delivered the classic line “here’s lookin’ at you, kid,” which Premiere magazine regarded as the greatest-ever movie line in 2007.

"I'm Singing in the Rain" Song (A Clockwork Orange)

The controversial 1971 Stanley Kubrick masterpiece A Clockwork Orange features a now-iconic scene in which Alex DeLarge (Malcolm McDowell) and his crew ruthlessly invade a wealthy couple’s home. It’s a violent moment in the movie, especially considering Alex is singing the innocent song “Singin’ in the Rain” while committing horrid acts.

You’d expect this brilliant scene to come straight out of Kubrick’s mind: mixing utter horror with a nostalgic American theme was refreshing, deeply philosophical, and highly contentious. Surprisingly, though, it was all McDowell’s idea, as he started singing the tune out of nowhere! Kubrick realized how genius it was immediately and decided to include it in the movie.

"Mein Führer, I Can Walk!" (Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb)

We need to go back to another Stanley Kubrick masterpiece to witness a moment of pure improvisational genius. In this anti-war comedy classic, Peter Sellers portrayed the Nazi scientist Dr. Strangelove, who was disabled. During filming, Sellers accidentally got up from his wheelchair; but instead of dropping the scene, he tried to get away with it by shouting, “Mein Führer, I can walk!”

The result? A bizarre moment that didn’t exactly fit in with the movie’s plot, but that provided the already weird character of Dr. Strangelove with yet another layer of mysticism and bizarreness. His shoutout to the Reich made up on the spot, tied the entire scene together.

"And He Invented the Mobile Disco" (Shaun of the Dead)

In 2004, director Edgar Wright made a huge impression with his comedy film Shaun of the Dead. The terrific movie combined lots of well-crafted visual jokes with an inventive cast responsible for creating some of the movie’s best lines on the spot. That includes the hilarious, “and he invented the mobile disco,” spoken at the Winchester pub scene.

The success of Shaun of the Dead may help to explain why Wright decided to collaborate with actors Simon Pegg and Nick Frost in most of his movies. Their improvisational skills and on-screen chemistry are a big part of what makes the director’s movies so funny.

"I Don’t Want to Go…" (Avengers: Infinity War)

If you still haven’t seen the Marvel movie Avengers: Infinity War, you should probably skip this one because we have some huge spoilers for you. Remarkably, the superhero flick is filled with tragic deaths of beloved characters, including the widely popular Spider-Man portrayed by Tom Holland.

Spider-Man’s death makes for one of the most emotionally charged scenes in the movie, with Peter Parker saying, “I don’t want to go...” moments before disappearing into thin air. It’s a great line, but it was apparently ad-libbed by Holland, who ended up making the scene a whole lot better with his instinctive unscripted line.

"I’m a Zit. Get It?" (National Lampoon's Animal House)

Every generation has a great teen comedy film. In the late ’70s, that film was National Lampoon’s Animal House, which relied heavily on John Belushi’s comedic talents. One of the funniest Belushi scenes in the movie? The time he pretends to be a zit while eating with the “cool kids” at the cafeteria.

Shortly after, Belushi’s character is chased by Kevin Bacon and his bully buddies. But remarkably, the now-iconic zit imitation was all Belushi since the actor wanted his character to feel more relatable. We have no doubt he achieved it because John Blutarsky is still one of the most beloved comedy characters in American cinema history.

"And What Did That Produce? The Cuckoo Clock." (The Third Man)

Orson Welles is a legendary figure in the mind of every movie buff out there, and rightly so. Besides being an outstanding director, screenwriter, and producer, Welles was also a very talented actor who knew how to deliver on the spot—even if his lines weren’t scripted!

A great example of that is his speech in Carol Reed’s The Third Man, a 1949 film-noir thriller about a man investigating a murder in postwar Vienna. In 2015, The Third Man made it back to the theaters after being digitally restored in 4K.

"I Am Hearing This, and I Want to Hear This" (The Devil Wears Prada)

The world’s greatest actors are also great observers who know how to study and copy people. And that’s precisely what Emily Blunt did in the 2006 comedy classic The Devil Wears Prada. Her now-famous line “I am hearing this, and I want to hear this” was reportedly inspired by a mom she overheard while filming.

The sentence stuck in Blunt’s head somehow and ended up being instinctively ad-libbed into the movie. At the time, screenwriters Aline Brosh McKenna and Lauren Weisberger had no idea it would be one of the film’s most memorable lines.

"Picture a Girl Who Took a Nosedive From the Ugly Tree" (Saving Private Ryan)

Most people call it locker room banter, but we have a new suggestion. Why not just go ahead and call it wartime banter? In Saving Private Ryan, the soldiers loved to engage in guy talk, and some of the best lines in the movie came out in these seemingly casual conversations.

One of the most iconic was the line mentioning a girl that’s so unattractive she looks like she “took a nosedive from the ugly tree.” Reportedly, this half-genius half-offensive line was never scripted and was created on the spot by Matt Damon, who was great in the role of Private Ryan.

"Why Male Models?" (Zoolander)

When you’re making a comedy movie, unscripted lines can sometimes be pure gold. But what about on-set mistakes? In the hilarious 2001 Ben Stiller flick Zoolander, Derek Zoolander (Stiller) asks J.P. Prewitt (David Duchovny) why the bad guys are using male models to fulfill their evil plans. Prewitt answers the question but, moments later, Stiller forgot his line and repeated, “Why male models?”

Duchovny ended up going through with the scene, and Stiller’s “mistake” ended up making for one of the funniest moments in the entire film. While it wasn’t scripted, it fitted perfectly with Zoolander’s utterly dumb personality. Also, we love actress Christine Taylor’s expression in this scene!

"Game Over, Man. Game Over!" (Aliens)

Released in 1986, Aliens still stands as one of the best movies in James Cameron’s filmography. It’s a beautiful action/sci-fi flick with lots of iconic scenes and a great cast led by Sigourney Weaver. One of the most memorable moments in the entire thing? Bill Paxton’s line, “Game over, man. Game over!”

When you watch it, it feels like it came from a moment of pure inspiration, and that’s because it genuinely did. Paxton’s character is not even on the frame when he desperately screams the famous line. Instead, the camera was focusing on the characters of Ripley (Weaver) and Newt (Carrie Henn).

"Kelly Clarkson!" (The 40-Year-Old Virgin)

Before becoming one of Hollywood’s favorite comedy actors, Steve Carell studied improvisation at The Second City Training Center in Chicago. But the waxing scene in The 40-Year-Old Virgin movie is more than just great on-screen improv. It’s a truly unhinged moment of cinema.

The scene makes for one of the funniest in the movie, probably because it was real. Yes, that’s Carell’s actual body hair being ripped off, and the actor’s painful screams don’t just feel authentic—they are authentic! Resisting the pain, Carell was still able to stutter some hilarious lines, even shouting Kelly Clarkson’s name for some reason.

"I Didn't Know You Could Read" (Harry Potter and the Chamber of Secrets)

This one’s very surprising, especially if you consider actor Tom Felton was just 15 when he delivered it. The line “I didn’t know you could read” was directed at the Slytherin bully Goyle, who was really Harry Potter in disguise (he drank the magical Polyjuice Potion).

While the line fits very naturally with the character of Draco Malfoy, it was never part of the script nor of J. K. Rowling’s books. It was a sheer moment of inspiration from Felton, who’s proven to have a knack for improvising on the spot.

"I've Been Impaled" (Frozen)

We know what you’re thinking: how on Earth did an animated movie make it to the list? Well, as it turns out, animated films can have ad-libs and improvised lines too, but they just have to be extremely good! After all, it takes a lot of hard work (and money) to change the animation to accommodate a new line.

A great example of a solid ad-lib that made it to the final version of an animated flick is Josh Gad’s “I’ve been impaled” line in Disney’s Frozen. Gad played the character of Olaf to perfection and was responsible for some of Frozen’s best comedic moments.

"I'll Have What She’s Having" (When Harry Met Sally...)

We’ve all seen it: rom-com queen Meg Ryan pretends to have the big O while at a coffeehouse, and a baffled customer responds by saying, “I’ll have what she’s having.” It’s arguably one of the funniest moments in the entire film, and this iconic line works as the perfect punchline to a scene that’s as steamy as it is cringy.

Surprisingly, though, the hilarious post-fake climax line was suggested on the spot by actor Billy Crystal and immediately recorded. It’s yet another piece of trivia that seems to prove that, when it comes to producing an iconic line, actors often know better than screenwriters!

"Know How I Know You’re Gay?" (Knocked Up)

Knocked Up is a movie about the joys and pains of growing up, and it simply wouldn’t be the same without Seth Rogen and Paul Rudd’s great on-screen chemistry. The two actors fitted brilliantly into the role of two young adults who, in their hearts, just want to continue to be teenagers.

The two actors loved to exchange burns, and there’s an entire scene in the movie comprised of nothing but unscripted insults between the two. It’s a lot of fun to watch, and it’s yet another big display of Rogen and Rudd’s improvisational talent.

"I Need a Vacation" (Terminator 2: Judgment Day)

In Terminator 2: Judgment Day, Arnold Schwarzenegger’s character is tasked with saving the world and forced to fight against a powerful cyborg that’s pretty much the upgraded version of himself. We know; it sounds like a lot of work.

That’s probably why Schwarzenegger ended up asking for a vacation in one of the movie’s funniest and most memorable lines. Reportedly, though, the line was never part of the script and was made up on the spot by the future Governor of California. It’s not “I’ll be back,” but it’s almost as good, and it made everyone at the movie set laugh.

"It's Such a Fine Line Between Stupid and Clever" (This Is Spinal Tap)

We’ve presented you with so many great improvised lines that you probably think actors are the real writers by now. Well, in This Is Spinal Tap, that concept really comes to life. After all, all three major stars of the “rockumentary” improvised their lines to the extent of receiving writing credits in the movie!

It’s an incredible feat for the likes of Rob Reiner, Michael McKean, and Christopher Guest, who were perfect in their depiction of a presumptuous English rock and roll band. Released in 1984, This Is Spinal Tap is still a cult movie and mockumentary reference today.

"And I... Am... Iron Man" (Avengers: Endgame)

In one of the most pivotal scenes in Avengers: Endgame, Thanos reprises one of his lines from Avengers: Infinity War by saying, "I am inevitable." In the script, Iron Man was supposed to simply snap his fingers in response and say nothing. However, the producers felt like the scene was missing something.

So they decided to also give Iron Man a reprised line, which was a throwback to the original 2008 Iron Man movie: "And I... Am... Iron Man." While the line may lack originality, it did make the scene a whole lot better.

"Sure... Where?" (Friends)

Friends is one of those shows that grows on you. What makes this an instant classic is that it ages so well, and the older you get, the more you can relate to it. Praises aside, Matthew Perry's character, Chandler, has been one of the most loved characters of all time.

Chandler's witty clapbacks made the show worthwhile, and Perry also improvised a few lines to perfection. In the show's finale, they decide to go for coffee at their favorite spot, and Chandler quips, "Sure... Where?" This wasn't part of the script, but it really connected well with the moment and the character.

Tom Selleck Reshooting his Entrance Scenes (Friends)

When Tom Selleck made guest appearances on Friends, his presence and aura had a huge impact on the audience and the fanbase. This is saying a lot considering he was only on ten episodes for its entire duration.

Despite this, what many people might not know is that the actor had such an electrifying persona that the audience would erupt whenever he made an entrance. This caused some issues for the editing and sound department, and they were forced to call Tom in to reshoot his entrance scenes after hours. Can you imagine being so popular that a walk-in scene had to be re-shot because you had too many devoted fans?

Jewelry Scene (Pretty Woman)

Pretty Woman is arguably one of the most iconic romantic comedies of the 20th century, and for a good reason. The chemistry between Julia Roberts and Richard Gere is so stimulating that it's hard to believe they are acting.

Surprisingly, one of the most interesting scenes was not part of the script. It's the scene where Richard offers Julia's character a necklace but closes the box just as she's about to place her hand on it. This scene was the work of the clever director who figured the original idea needed some pizazz, and that's why Julia's reaction is true to life.

Baby Talk (When Harry Met Sally)

The movie When Harry Met Sally has so much improvisation that it's hard to tell where the scripting ends and the improvisation begins. It's a whirlwind of incredible improvised scenes combined with stellar performances.

In one particularly famous scene, the director had asked Meg Ryan to wing it and draw whatever came to mind when she thought of "baby talk." The result was an indecipherable mess that led to the famous "Baby Fishmouth" response. It was a game of charades, and the other cast members had to guess what was being drawn, and we must say Meg did accomplish her task as baby talk is indecipherable.

Patricia Velasquez's Horror Experiences (The Curse Of LaLlorona)

Many people look at horror movies and think that's just a bunch of hogwash and practical effects. Nevertheless, during the filming of The Curse of La Llorona, Patricia Velasquez had an exciting experience that impacted her.

The actress has always known about La Llorona since she was a child as it's part of her culture, and it was interesting to portray such a scary figure from her childhood. According to Patricia, the shooting went well, but they shot in a haunted mansion, and things were actually spooky. One of the crew member's bracelet exploded, and she had a wonky experience herself. We definitely wouldn't want to be in her shoes.

Michael Landon Was Jewish In Real Life (Little House on The Prairie)

It is surprising to learn that Michael Landon was Jewish in real life for someone who successfully portrayed a Christian role. But, of course, we are referring to the actor's character in the light-hearted TV series known as The Little House On The Prairie.

When asked about this unique situation, Michael was always honest about it and said he never found an issue with it. The job and his personal life were separate entities, and there was no need for a conflict of interest. We can't help but admire Landon's professionalism and dedication to the cause, as some people might think about giving up along the way.

Not New Friends (Little House On The Prairie)

Despite winning an award for her role on The Little House On The Prairie, Melissa Sue Anderson didn't have a rosy review from the rest of her castmates. This was due to the fact that she wasn't as friendly and interactive as they'd have liked.

Some people blame it on the actress's sheltered upbringing, and it was quite unfortunate that Melissa's castmates never saw her as a sister figure all through the shooting as much as she portrayed the big sister. It shows how weird things can get behind the scenes.

Bad Advice (Citizen Kane)

Norman Lloyd passed away at the ripe age of 106 in his sleep, but his legacy will continue to inspire us. The legendary actor began his career in a theater where his initial projects were a success.

Lloyd's fame pushed him to get his first Hollywood role, where he was cast as part of a film titled Heart of Darkness. Unfortunately, due to budgetary constraints, the project was scrapped, but the director asked the cast to stay put as he put something together. Sadly, Lloyd was ill-advised and chose to return home, and this ended up costing him greatly as he missed the opportunity to mark his debut with an appearance in Citizen Kane.

Granny's Slaps ( The Beverly Hillbillies)

Despite its abrupt cancellation, The Beverly Hillbillies was an amazing comedy way ahead of its time. The premise was simplistic, but it had some weight at the core and genuinely raised some modern-day questions. The cast always had fun on set, and as expected, they had stories to tell.

Irene Ryan, who portrayed Granny Clampett, was a sweet lady in real life, but her character was far from that. In many scenes, Granny was the no-nonsense tough lady who always slapped sense into Jethro. During an interview, Ryan once confessed that the slaps were real but judging by her hands' size, they didn't do any damage.

"I've Always Wanted A Man Like Tom Hanks" (How to Lose a Guy in 10 Days)

How to Lose a Guy in 10 Days is a rom-com masterpiece that we all watched and savored, even the ones who are not-so into "chick flicks," thanks to the iconic contribution of Kate Hudson and Matthew McConaughey. Interestingly, the director of the movie encouraged improvisation to keep things real.

Remember the dialogue, "I've always wanted a man like Tom Hanks"? Yes, the actress ad-libbed it during the famous scene where they went to watch Sleepless in Seattle. The star indeed took the command seriously! We all do, Kate!

Laura San Giacomo (Pretty Woman)

Laura San Giacomo portrayed a call-girl alongside Julia Roberts in the critically acclaimed movie Pretty Woman. Their scenes together had a sisterly vibe that very few actresses can pull of as genuinely as they did. Some might have even argued that the scenes were not scripted and couldn't have been more right.

In a new interview, the prolific actress revealed that Garry Marshall prompted and greatly encouraged her to improvise some of her scenes. This was a big deal for the then young actress, and she definitely took the opportunity seriously. The fact that we can't pinpoint the scripted and improvised scenes says a lot.
