Every top quality movie takes a little creative improvising, and sometimes, those accidents can create some really great moments. Whether it's a line made up on the spot or an injury that fits perfectly into a scene, some moments are worth keeping in the final cut. Read through to find out which movies included their most hilarious or unsettling bloopers... 

Anchorman

"I'm in a glass case of emotion!" was a line that took the internet by storm, becoming a popular reaction image to overwhelming things, but this line was nowhere in the original Anchorman script. Instead, the director encouraged the entire cast to get creative with their lines. After all, the cast was full of improvisers and famous comedians. The result was guaranteed to be incredible.

Jaws

Jaws is filled with famous quotes, but none were quite as big as "You're gonna need a bigger boat." This line wasn't exactly in the original script but wasn't thought up off the cuff either. It was a joke among crew members who were having trouble filming on the small boat. They frequently said, "We need a bigger boat!" Everyone liked how it sounded, so it was changed slightly and put in the script. 

A Few Good Men

You can't handle the truth, but the truth is, this line was an accident. The line was originally supposed to be "You already have the truth" but Jack Nicholson said this one when he forgot the line. The director was absolutely stunned and demanded the improvised line be included in the final version. It has become one of the most famous quotes in movie history. 

Goodfellas

The entire rant about being funny was made up on the day of shooting. The. Entire. Thing. From "I'm funny how? I mean, funny like I'm a clown? I amuse you? I make you laugh?" all the way down to Tommy declaring to Sonny "Yeah, alright. For $7,000, I charge you." The script just said to go on a rant, and Joe Pesci thankfully more than delivered on that front... 

Casablanca

The line "Here's looking at you, kid" came as a result of a surprisingly good poker game. Humphrey Bogart was teaching his costar, Ingrid Bergman how to play the game of poker when she made a shockingly good play and won it all. He responded to her quick cleverness by saying the famous line. They both liked the way it sounded, so they included it in the scene. 

Midnight Cowboys

New York City is a wild town, and no one knows that better than the cast and crew on Midnight Cowboy. When filming, Dustin Hoffman really did almost get hit by a rogue taxi cab. His response, "Hey I'm walking here!" was a genuine reaction to the car's interruption! They both managed to stay in character though, so it became a hilarious and historic ad-lib. 

Taxi Driver

"Are you talking to me. Are you talking to me... Well, I'm the only one here." This monologue might be Robert DeNiro's most famous lines in his whole career, but the Taxi Driver star didn't have any guidelines for this scene. His script simply said that he was supposed to talk to himself in the mirror. He didn't prepare anything, so on the day of shooting, he came up with the lines. 

Harry Potter and the Deathly Hallows, Part 2

The Harry Potter franchise's final movie had to be as perfect as possible. The make sure of this, Voldemort's Ralph Fiennes said his lines out of order and did different actions so that none of the other actors would get lazy with their lines. Everyone was on their toes when Ralph was on-screen, just like how they would be if confronted with the real Dark Lord, Voldemort. 

Good Will Hunting

Robin Williams is the King of Comedy, but this movie is hardly a comedy at all. So when he was trying to come up with a line for the final scene, he tried out tons of possibilities. At one point he just half-heartedly sighed "He stole my line." and the directors knew it would be a keeper. He apparently tried out a few more lines, hoping for something better, but nothing stuck quite as well. 

Ghost

"Molly, you in danger, girl," was a line delivered by Whoopi Goldberg as Oda Mae Brown in this 1990 film. She warns Molly about Sam, as she is Molly's psychic. Whoopi improvised several of her lines in this iconic romantic film, including this internet favorite. Today, it is popularly used in memes and internet captions. She earned an Academy Award for her performance. 

The Spinal Tap

"There's a fine line between clever and stupid" is the takeaway from this metal band movie. Apparently, this movie had so many clever improvisations that the three main actors got writing credits for all their help to the final product. The film was directed by Rob Reiner and was written by Christopher Guest, Rob Reiner, Harry Shearer, and Michael McKean...

A Clockwork Orange

The singing in the rain sequence was completely made up behind the scenes of shooting. Malcolm McDowell just happened to be singing it while waiting to start shooting, but Stanley Kubrick loved the tone that it set for the character. He was encouraged to sing and dance in front of the lens, and it became an iconic opener for one of the wildest movies ever produced. 

Dazed and Confused

For anyone who's ever impersonated Matthew McConaughey's iconic line "alright, alright, alright," you might be surprised to learn that this line wasn't in the original script. Matthew McConaughey wasn't even supposed to be in the movie! He had a small part that skyrocketed his career and made him a standout star from the flick. Now that's pretty alright, alright, alright...

The Shining

Jack Nicholson really leaned into his role in this horror thriller. He cut through over sixty doors before the crew got the perfect shot. The craziest part of this is that he didn't have a specific line. "Here's Johnny" was just the best take of the door cut, so the editors were pretty much forced to include the line in the final version. Luckily, it became a hit, but allegedly Nicholson hated the dialogue. 

When Harry Met Sally

One of the best romantic comedies of the modern age is When Harry Met Sally and these two actors needed to make sure their chemistry on the screen seemed genuine. For that reason, director Rob Reiner encouraged the duo to have fun with their conversations. It needed to seem authentic, so when Harry (Billy Crystal) says "I would be proud to partake in your pecan pie," that was just off the brain. 

Young Frankenstein

Who says old movies can't be hilarious? When Igor from Young Frankenstein is talking to the Doctor, some fans might notice the easter egg that the hump on his back keeps changing sides. What the fans might not know about is that Igor improvises one of his lines. The doctor says he might be able to help him out with the hump, and Igor responds "What hump?" That was ad-libbed!

The Devil Wears Prada

Before shooting one scene for The Devil Wears Prada, Emily Blunt stopped into a shop where she saw a mother and daughter fighting. The mother said "I'm hearing this" and made a talking motion with her hand, "And I want to hear this," and made a closed mouth motion with her hand. Emily thought it'd fit perfectly with her tired and overworked character. 

Saving Private Ryan

"I mean, picture a girl who just took a nosedive from the ugly tree and hit every branch coming down," is the story of a girl named Alice Jardine from Private Ryan's hometown. This entire monologue was actually made up on the spot by Matt Damon himself. He was just instructed to tell a story and he was able to make up this entire fictional tale at the drop of a hat...

Bridesmaids

Melissa McCarthy stands out in this movie filled with hilarious comedians. Apparently, most if not all of her lines on the airplane were improvised. Directors wanted the improvisers to do what they do best, and they didn't disappoint. Melissa was also working opposite her husband, which made acting out the more uncomfortable lines that much more hilarious.  

Frozen

Animated movies leave a lot of room for actors to have fun with their characters and scripts since they don't have the normal limitations. So, when Josh Gad, the voice of Olaf the Snowman joked that his character was impaled by a pointed icicle, animators loved the ad-lib. The little adorable snowman got a fairly dark joke in the final animation, much to Gad's delight. 

Lost in Translation

Scarlett Johannson and Bill Murray became very close in the filming of this movie, closer than viewers ever got to find out. When the movie ends with a heartfelt goodbye, the actors were supposed to join hands, but instead, Bill took matters into his own hands (and ScarJo's ears). He whispered something in her ear that made her smile, but neither has ever revealed what he said. 

Thor

Anthony Hopkins played the part of Odin, aka the father of Loki (Tom Hiddleston) and Thor (Chris Hemsworth). When he's yelling at Thor, Loki steps in to uncharacteristically defend his brother.  Odin then growls at his son, which Hiddleston didn't expect. The reaction on his face is a genuine surprise reaction. The actors had trouble finishing the scene without laughing!

Zoolander

Zoolander was a surprise hit comedy from the mind and acting skills of Ben Stiller, who played the titular dimwitted male model used as a brainwashed pawn in an assassination scheme. He goes to meet with a hand model and asks the question "Why male models?" which prompts the explanation. After the explanation, he asks again "But why male models?" Turns out Stiller just forgot his line!

Captain America: The First Avenger

Steve Rogers captured hearts for generations, both in this universe and in the Marvel world. When Peggy Carter meets the mythical man for the first time, she is awestruck by his good looks and fine physique. This reaction was completely authentic as Hayley Atwell had never seen the star bare-chested before. She wasn't even supposed to touch him, but she couldn't help herself. Do you blame her?

Clueless

Donald Faison wanted to make sure his goofy but lovable character seemed as authentic as possible. His line "I'm just keeping it real" came from a local boy in his neighborhood that he had overheard talking to friends. He thought it sounded very natural and genuine, so he tried to keep the same cadence and delivery for his performance as Murray Duvall, Dionne Davenport's boyfriend. 

Guardians of The Galaxy

Rocket Raccoon wasn't as famous as Groot, but at least everyone knew what he was saying, even if it wasn't very nice. One line came straight from the mind of actor Bradley Cooper who voiced the animal. When, during a very serious moment, the team stands up in solidarity, Rocket says "Now I’m standing, you all happy? We’re all standing up now. Buncha jackasses standing in a circle."

Harry Potter and the Chamber of Secrets

Kids can be just as clever as some adults writing these screenplays. Tom Felton, famous for playing Draco Malfoy in the Harry Potter franchise, came up with this clever joke when he forgot his next line. When one of his cronies said he used glasses to read, and he quickly responded with "Reading? I didn't know you could read." They kept it in so he'd be seen more as a bully than a villain, an important distinction in the Harry Potter universe. 

The Avengers

Tony Stark likes to keep snacks on hand, and by Tony Stark, that means Robert Downey Jr. The actor has such an obsession with snacking that his blueberries scene only happened because he happened to be eating blueberries during filming that day. Everyone on the cast played around with his ridiculous blueberry offer, but that was nowhere in the initial draft. 

The Godfather

The little cat on this man's lap might seem like a carefully crafted character trait, but such is not the case. The cat was a stray that had wandered into the studio by mistake. The little guy took a liking to Marlon Brando, and he didn't want to let him go. Luckily for both of them, the cat was the perfect humanizing element to this brutally vicious mob boss character...

The 40-Year-Old Virgin

Steve Carrell is a comedy legend, and that might be due to his dedication to the joke. For example, the waxing scene in the 40-year-old virgin was all painfully real (emphasis on painful). However, the many expletives Steve screams out were all made up at the moment. So when he screamed out "Kelly Clarkson!" instead of a curse word, that was his genuine reaction...

The Dark Knight

Every excellent performance deserves a slow clap, except for maybe the Joker's performance, which had a slow clap included in his scene. Heath Ledger incorporated this detail because, while he admired other representations of the character, he always imagined the villain to be a little more cunning, clever, and most of all, sarcastic. The slow clap depicted all of that perfectly. 

Rocky

Though Rocky was an extremely successful film, it started with almost no budget. Because of this, the casting couldn't afford to pay for extras. As a result, most of the background people in the film didn't even know they were going to be in the final version. When the man in the street throws an orange to Rocky, that was a real guy improvising. Ah, the city of brotherly love!

The Lord of the Rings: The Two Towers

Eowyn is a noblewoman looking out over the kingdom when the flag flys away from the long post. While viewers might have thought this was a preplanned metaphor or heavy-handed symbolism, it was actually just a mistake of the wind and poor attachment. Since it obviously fits perfectly with the tone of the scene, editors had to keep it in the final cut. Thankfully, Miranda Otto didn't break character.

Mrs. Doubtfire

Leave it to Robin Williams to take a funny mistake and make it a legitimate piece fo comedy. In the scene where Williams covers his face in cake icing, the makeup artist didn't account for the hot studio lights and the icing quickly started melting off. When the sweet treat falls into the coffee, Williams simply says "Well, now you've got your cream and sugar!" 

Dirty Dancing

Dirty Dancing is one of the most iconic films of all time. After all, no one puts Baby in the corner. Did you know though, that the memorable crawling scene came as the result of the two actors goofing around with each other while warming up? They didn't realize the camera caught them practicing, and the editors thought the clip would work well in the final film. 

Raider's of the Lost Ark

Even Indiana Jones has his off days. When shooting an epic duel scene, Indy showed up to set with a terrible case of food poisoning. Instead of engaging in a battle to the death, the scene was rewritten to Indiana Jones pulling out a gun to kill his enemy. The scene is now one of the most recognizable and replicated in all of cinema history, all because of some bad seafood...

Guardians of the Galaxy

Chris Pratt is quite the goofball on set, but that can definitely work well for his character, Star-Lord, from Guardians of the Galaxy. In one scene, he is supposed to hold up the orb but accidentally dropped it. Thankfully, he didn't get out of character so the scene could still be used in the final cut. Directors loved the carefree attitude that Pratt is known for, and now, so is Star-Lord!

Thor: The Dark World

Just because you're saving the universe doesn't mean you can't have some manners. When Chris Evans was filming this scene for Thor: The Dark World, he came up with this funny addition of hanging up his hammer on the coat rack. The directors weren't exactly keen on the actors improvising comedy, but even they had to admit that this scene was too good not to include. 

Star Wars: The Empire Strikes Back

Some creative liberties were taken with Han Solo when filming Star Wars: The Empire Strikes Back. When Princess Leia (Carrie Fisher) professes her love to Han Solo (Harrison Ford), he was supposed to respond with "I love you, too" but clearly, that didn't pan out. Instead, Harrison Ford thought his character wouldn't be so straightforward. and replaced the phrase with "I know."

Forrest Gump

Forrest Gump is hailed as one of Tom Hanks' best works, but maybe the most moving part of the film is his relationship with his best friend Bubba. When the two new recruits meet, Bubba introduces himself to Forrest by saying "My name is Benjamin Buford Blue, but people call me Bubba." Forrest's response to this was improvised by Hanks, who says "My name is Forrest Gump, people call me Forrest Gump."

Iron Man

Tony Stark is known for having a pretty big snacking habit, but all of that chowing down comes from Robert Downey Jr.'s own eating. Apparently the actor kept sneaking food onto the set, so much so that he would have it next to him in scenes. Directors just decided to include it in the character rather than yell at him to put the pizza down. So all the food he's eating? All craft services. 

The Princess Diaries

The Princess Diaries told girls everywhere that they could become royalty at any moment, even if they were as dorky as Mia Thermopolis (Anne Hathaway). When Mia is walking on the bleachers with her best friend, she accidentally falls down in between the seats. This accident wasn't scripted, but fit well with the character's clumsy and nerdy nature, so it was kept. 

Django Unchained

While filming Django Unchained, there was a bit of an accident on set. While shooting one scene, Leonardo DiCaprio slammed his glass down, causing it to shatter in his hand. Rather than stop to be healed, he continued with the scene. No one broke character despite the bloody accident, and this was the shot that made it into the final cut of the film. now that's some real commitment to the craft...

Silence of the Lambs

Jodie Foster (playing Clarice Starling) had no idea that Dr. Hannibal Lecter (played by Anthony Hopkins) was about to make that weird hissing noise. He added that in at the last minute, as a way to make the character more unsettling (as if being a serial killer wasn't unsettling enough?) Jodie's reaction to the noise was incredibly authentic, she was as shocked as the audience. 

Titanic

"I'm the king of the world!" was not in the original Titanic script. In fact, Leonardo DiCaprio tried out tons of different ad-libs before James Cameron settled on this one. He didn't even like it either! He thought it was cheesy and unrealistic, but the crew had to continue with shooting to stay on schedule. So, even though it became hugely popular, James Cameron still cringes at this line. 

The Usual Suspects

Everyone gets a case of the giggles every now and then, but it was the cast of The Usual Suspects who took this to the next level. When the group started laughing so much that they couldn't stop, the editors were forced to include it in the final cut. The actors just couldn't hold it in long enough to finish the shot, and the result was one of the best scenes of the film. 

Eternal Sunshine of the Spotless Mind

Absence makes the heart grow fonder... unless you're Jim Carrey in the movie Eternal Sunshine of the Spotless Mind. In one scene, he was about to start shooting a part where his girlfriend disappears but wasn't told she would no longer be in the shot. The look of confusion on his face was genuine as he kept trying to figure out where the costar had gone and why she wasn't on time! 

Full Metal Jacket

Full Metal Jacket is remembered as Stanley Kubrick's take on the violence of the Vietnam War. The drill instructor, Hartman, was originally hired as a consultant on the set. He was so helpful and knowledgable that the casting directors decided to cut out the middle man and cast Lee Emery in the role! Almost all of his dialogue was improvised based on his own experiences. 

Rain Man

Some bloopers are better than others, like when Dustin Hoffman really did pass gas in the telephone booth scene of the Rain Man movie. Tom Cruise just went along with it but didn't break character. Although it smelled gross, it made the scene way funnier and became one of the most memorable moments from the blockbuster. Talk about taking one for the team...

Scent of a Woman

This 1992 movie follows a prep schoolboy that is tasked with caring for a blind veteran. Al Pacino wanted to do right by his role, so he practiced going blind by unfocusing his eyes as much as possible. Well, he got a little too good at this and it started happening without his doing! One of these times, he walked straight into a trash can, which of course made it into the final film. How could it not? 

Fast and Furious 6

When Dwayne "the Rock" Johnson comes onto the scene in Fast and Furious 6, Roman shouts out "Hey, better hide the baby oil!" Dwayne, who plays Hobbes, immediately comes back with "You better hide your big a** forehead!" This exchange was not in the script, but just some jovial improvising. It was so funny and unexpected that Ludacris spits out his drink onto the table. 

Blade Runner

Though it might have looked cool, the scene where Daryl Hannah runs out into the rain, she breaks a van window with her elbow. It looks pretty impressive, but it ended up breaking her arms. She continued with the scene until the end, but afterward, she was quickly rushed to the hospital. She had a cast on for a few weeks, and filming had to pause while she recovered from the injury. 

Wolf of Wall Street

This weird scene between Leonardo Dicaprio and Matthew McConaughey actually came from a warm-up exercise done by McConaughey in his dressing room. it's a relaxation technique he's been using for years. Martin Scorsese loved the quirky trait and decided to include it in a scene. The pounding on the chest is supposed to mimic a calmed, relaxed heart beating. 

Lock, Stock, and Two Smoking Barrels

Nick the Greek angrily slammed down a juice glass and broke the whole table. While it looked pretty cool in the movie, it was actually nowhere in the script. Nick, who's actually Stephen Marcus, just had a little more power than he anticipated. No harm, no foul though, as this became one of the most memorable moments in a largely forgotten movie from 1998. 

Scream

Scream set a new precedent for horror movies, and the character Stuart reminded people that the killer could be anyone, even those closest to the gang. In one scene, Stuart opens a drawer expecting to find a gun. When it's not there, he says "Houston...we have a problem." This line was improvised at the moment, and also a total lie since he already knew the weapon was gone. 

The 'Burbs

Patience is a virtue, but one that Tom Hanks character in The 'Burbs did not possess. While waiting for some medical treatment, he gets impatient and throws the gurney into the back of the ambulance. It was something he made up at the moment, but also one that he said felt fitting for his character, Ray Peterson. When you need help, you got to do whatever it takes to get it. 

The Other Guys

Ah, the famous 'Lion vs. Tuna' conversation. "Okay, first off, a lion swimming in the ocean? Lions don't like water. If you'd placed it near a river or some sort of freshwater source, that'd make sense. But you find yourself in the ocean, 20-foot waves, I'm assuming it's off the coast of South Africa, coming up against a full-grown, 800-pound tuna with his 20 or 30 friends? You lose that battle." This entire scene and more was entirely made up, are you surprised with these two comedy legends?

American Beauty

Kevin Spacey stars in this 1999 fan-favorite. In one scene, Spacey's role called for him to throw a plate onto the floor. Instead, though, he picked the plate up and slammed it against the wall. Thora Birch really did jump at the move because she wasn't expecting it. The film has been described as "An incisive, deliriously funny and profound vision of the American Dream hitting meltdown."

The Amazing Spiderman

The Amazing Spiderman follows Peter Parker (Andrew Garfield) as he seeks to take down the Lizard aka Dr. Curt Connors. In one scene, Parker tries to go to the police to warn them of a giant lizard man, to which one officer responds "Do I look like the mayor of Tokyo?" This reference to Godzilla was made up on the spot, and seemed so natural that scriptwriters didn't even realize it wasn't their writing!

The Incredible Hulk

At the end of The Incredible Hulk, in traditional Marvel Cinema movie fashion, there was an extra scene at the end of the credits sequence. For fans who waited until the very end, you might have caught Robert Downey Jr. talking about putting together a team, presumably the Avengers. The entire scene had only one guideline--mention the Avengers. Everything else was unscripted. 

Ant-Man

Ant-Man was a surprise hit, with Paul Rudd playing the tiny superhero. He holds several discussions with his ex-girlfriend, but these and more conversations were mostly improvised. In fact, Rudd and his co-star Michael Pena claimed to have improvised at least 50% of their lines in the film. This movie barely even needed a script to create the final product. 

Avengers: Age of Ultron

Quicksilver and Hawkeye developed an interesting friendship over the course of this blockbuster. When Quicksilver escapes from the famed archer, Hawkeye says to himself "Nobody would know… 'last I saw him, Ultron was sitting on him!'" This was a line that Jeremy Renner came up with on his own, but it fits perfectly with his character, and that became his funniest moment in the film. 

The Avengers

At the end of The Avengers, the team decides to rally together and eat some shawarma after a long time of fighting crime nonstop. This is a reference to a line Tony Stark improvised, when asked "what's next" earlier in the film, he replies to the Hulk saying that the crew should meet up later to get food, preferably some kind of Mediterranean grub. The RDJ line influenced the final scene of the flick...

Guardians of the Galaxy

Star-Lord is not from any famous comic book or as popular as Star Wars but became a hero nonetheless. Writers decided to poke fun at this unpopularity by introducing the character being disappointed that his captors don't recognize him. The gag was a result of a conversation between Chris Pratt and director James Gunn, who wanted to highlight the hilarious new hero.
