Have you ever looked back at some of the most famous movie quotes and wondered how the screenwriter could have come up with that? Well, believe it or not, some of those memorable lines (and even some iconic moments in their entirety) were not part of the script and were invented on set and even on the spot while the camera rolled, either out of incident or by some instance of spontaneous creativity. The following are some of the most legendary examples of improvised moments from the movies.

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

There is some debate regarding if the most oft-quoted moment from the X-rated Best Picture Oscar winner, 1969’s Midnight Cowboy, was really off the top of Ratso actor Dustin Hoffman’s head. However, the Academy Award winner claimed to The National Post that, on the first take, a cab pulled out right in front of him, to which he responded with genuine frustration, “I’m walkin’ here!” while managing to stay in character.

"Here's Johnny!" (The Shining)

Despite being one of the most iconic moments from one of the best horror movies of all time, Jack Torrance screaming “Here’s Johnny!” after axing his way through a bathroom door feels slightly out of place in 1980’s The Shining. That is because, according to The Independent, Jack Nicholson ad-libbed the line, which Stanley Kubrick initially did not realize was a reference to Ed McMahon’s catchphrase from The Tonight Show Starring Johnny Carson.

"Alright Alright Alright" (Dazed And Confused)

A phrase that will forever be associated with Academy Award winner Matthew McConaughey is also on the funniest lines from 1994’s Dazed and Confused: “Alright alright alright.” He explained to Kelly Ripa and guest host Christian Slater on Live! that the first words he ever spoke on film were a spur-of-the-moment way of expressing “confirmation” for the three most important things in David Wooderson’s life: his car, rock ’n roll, and illicit substances.

Edward Closes The Jewelry Box On Vivian (Pretty Woman)

The signature moment from 1990’s Pretty Woman when Edward (Richard Gere) snaps a jewelry box lid on Vivian’s (Julia Roberts) hand was nothing more than a prank on the then 22-year-old actor in an effort to “wake her up a little. Director Garry Marshall revealed this to ET, who agree that it is the moment America “fell in love” with the future Academy Award winner and makes it thankful the blooper made the final cut.

Aragorn's Furious Cry (The Lord Of The Rings: The Two Towers)

In 2002’s The Lord of the Rings: The Two Towers, Aragorn (Viggo Mortensen) sounds like he is in genuine pain when he, after witnessing a pile of dead orcs, kicks a helmet and lets out a bloodcurdling yelp. That is because, as Peter Jackson revealed on a making-of featurette, when the actor’s foot hit the solid metal helmet on the fifth take, he broke two of his toes, resulting in the impassioned scream.

Matt Damon in Saving Private Ryan

Ryan's Last Memory Of His Brothers (Saving Private Ryan)

In Steven Spielberg’s Saving Private Ryan, Captain John Miller (Tom Hanks) learns that the titular soldier he and his crew have been tasked with rescuing is not the most noble gentleman when he recalls the last time he saw his brothers alive. According to Peter Bart’s book, The Gross, Matt Damon came up with the darkly comic story involving a young woman knocked unconscious and a barn nearly burnt to the ground the day it was shot.

"Are You Talkin' To Me?" (Taxi Driver)

Not only was Robert De Niro’s legendary “Are you talkin’ to me?” speech from 1975’s Taxi Driver not in Paul Schrader’s script, but the entire scene almost did not happen because the film was behind schedule. Director Martin Scorsese told Stephen Colbert on Late Show that, in the moment, he had convinced his producers to let him keep shooting the ad-lib to its completed form.

"I Don't Want To Go!" (Avengers: Infinity War)

Tom Holland revealed in a video for GQ that a technique he uses to cry on command is repeating a tonally appropriate phrase in his head until the tears well up. The phrase he chose for the scene before Peter Parker turns to dust in Avengers: Infinity War was, "I don't want to go!" which he, instead, decided to say out loud to Robert Downey Jr.’s Tony Stark, perfecting the devastating moment from the 2018 Marvel flick.

Andy's Chest Wax (The 40-Year-Old Virgin)

One of the most unsettling behind-the-scenes facts of all time is that Steve Carell requested that Andy’s famous chest waxing scene in 2005’s The 40-Year-Old Virgin be real and shot in one take, as he recalled in a BBC Radio 1 interview. While many of the things that he says were previously written — including “Kelly Clarkson!” which came courtesy of Seth Rogen — each of Carell’s painful reactions are genuine

The Most Annoying Sound In The World (Dumb and Dumber)

Many of Jim Carrey’s best quotes came right off the top of his head, including one of the funniest moments from 1994’s Dumb and Dumber. Jeff Daniels confirmed in a video for GQ that he was surprised when his co-star blurted out “the most annoying sound in the world” in the middle of a take.

Lecter Mocks Starling's Accent (The Silence Of The Lambs)

When discussing ad-libs from 1991's The Silence of the Lambs, most people reference Hannibal Lecter's iconic hiss, but that allegedly improvised choice is not the only moment of that kind from Clarice Starling's first meeting with the psychopath. Jodie Foster revealed in her MasterClass episode that Anthony Hopkins came up with the idea to mock her character's accent off the cuff, which initially frustrated the actor, but ultimately added a fascinating layer of manipulation to the role.

Lee Ermey in Full Metal Jacket

Most Of Sgt. Harman's Dialogue (Full Metal Jacket)

While R. Lee Ermey did not exactly come up with his lines as Gunnery Sergeant Hartman on camera, much of his dialogue from Full Metal Jacket was created off the top of his head beforehand. The former Marine revealed in an interview with The History Channel that he would improvise lines reminiscent of his days in the service in front of a tape recorder and the "juiciest" lines were added to the Oscar-nominated script.

Tom Holland in Spider-Man: Homecoming

Peter Hugs Tony (Spider-Man: Homecoming)

What makes Tony Stark and Peter Parker some of the funniest MCU characters is the brilliant way Tom Holland and Robert Downey Jr. manage to play off each other in the moment, such as one memorable moment from 2017’s Spider-Man: Homecoming. Holland told Kevin McCarthy from Fox 5 in Washington DC that he thought it would be funny if the teen otherwise known as Spider-Man hugged the man otherwise known as Iron Man as he was opening a car door for him, and he turned out to be right.

Will Ferrell gets ready to shout behind Faizon Love in Elf.

Buddy's Excitement About Santa (Elf)

Elf might not have become one of the funniest Christmas movies ever if not for Will Ferrell’s commitment to the role of Buddy and his off-the-cuff comedic talent. According to a video by Rotten Tomatoes, the North Pole-raised human’s irritatingly loud reaction to learning “Santa” is visiting Gimbel’s came out of the former SNL star’s belief that his response would have to be the most “jubilant” possible.

Robin Williams in Good Will Hunting

"He Stole My Line" (Good Will Hunting)

Will’s (Matt Damon) final message to Sean (Robin Williams) in 1997’s Good Will Hunting, which mentions having to “see about a girl,” is a callback to a story his therapist told him earlier, which he points out by saying, “He stole my line.” Damon revealed in a video for Vanity Fair that the late comedian’s final quote in the movie was not in his and Ben Affleck’s Oscar-winning screenplay, but he knew the moment he heard it that nothing could have ended the film better.

Cannoli scene from The Godfather

“Leave The Gun. Take The Cannoli” (The Godfather)

A look back on many of the most iconic lines from Francis Ford Coppola’s The Godfather by THR reveals that one quotable moment was not originally written the way it was said in the final product. Richard Castellano, as Peter Clemenza, was only supposed to say, “Leave the gun,” but Ardell Sheridan (his real-life and onscreen wife) recommended he add, “Take the cannoli,” in reference to an earlier scene when her character asks him to bring dessert.

"I Love Lamp" (Anchorman: The Legend Of Ron Burgundy)

When Brian Fantana (Paul Rudd) points out that Brick Tamland (Steve Carell) is "just saying things [he's] looking at," that was, indeed, exactly what Carell was doing. According to Page Six, he did not have any lines for the scene in 2004’s Anchorman: The Legend of Ron Burgundy, so director Adam McKay instructed him to just say whatever came to mind.

Jack Nicholson in A Few Good Men.

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

Do you think you can handle the truth about the most celebrated line from 1992 A Few Good Men? According to Judith Humphrey’s book, Impromptu: Leading in the Moment, Col. Nathan Jessup’s (Jack Nicholson) final stinger in his courtroom face-off with Lt. Daniel Kaffee (Tom Cruise) was originally written by Aaron Sorkin as “You already have the truth,” but the Academy Award winner changed it on the spot.

The Pecan Pie Scene (When Harry Met Sally...)

In the 1989 romantic-comedy movie classic, When Harry Met Sally…, Harry’s random decision to have him and Sally speak in a strange accent and converse about having pecan pie was really as spontaneous as it feels. As Billy Crystal shared on The View (via Business Insider), he provided no warning about the bit to Meg Ryan, whose look to the side at one point was to director Rob Reiner, who silently instructed her to go along with it. 

Heath Ledger in The Dark Knight

Joker Applauds Gordon's Promotion (The Dark Knight)

Despite what rumors have suggested, Heath Ledger’s playful reaction to the delayed hospital explosion in 2008’s The Dark Knight was not improvised. However, Christopher Nolan told BBC Radio 1 that the late Oscar winner did come up with a lot of memorable moments on set, including when Joker sarcastically claps after Jim Gordon (Gary Oldman) is appointed Commissioner.

The Laugh-Filled Police Line-Up Scene (The Usual Suspects)

Have you ever wondered why 1995’s The Usual Suspects cast starts to randomly break into laughter while grouped together in a police station line-up? Kevin Pollack revealed on a DVD extra that, which you do not hear in the final cut, Benicio del Toro started breaking wind and did so enough times to send his co-stars reeling.

Matthew Lillard in Scream

"My Mom And Dad Are Gonna Be So Mad At Me!" (Scream)

As he revealed in a joint EW interview with him and Skeet Ulrich, Matthew Lillard ad-libbed several of Stu Macher’s lines from the climax of Scream. This includes his especially iconic response to learning that Sidney (Neve Campbell) called the police and him and Billy (Ulrich).

Edward Norton and Brad Pitt in Fight Club

“You Hit Me In The Ear!" (Fight Club)

Apparently, the first time the Narrator throws a punch at Tyler Durden in 1999’s Fight Club was really as painful as it looks, as Edward Norton told Jimmy Fallon on The Tonight Show. Director David Fincher instructed him to hit Brad Pitt for real and he ended up hitting his co-star in the ear, leading to Pitt's genuine reaction.

David Patrick Kelly in The Warriors

Luther Taunts The Warriors (The Warriors)

For the final scene of the 1979 thriller, The Warriors, director Walter Hill wanted to add more to the scene and asked David Patrick Kelly, as Luther, to help add something to spice things up. The actor recalled to Book and Film Globe how he decided to put three glass bottles on his fingers, clink them, together, and come up with his iconic chant, “Warriors, come out to play!” on the fly.

David Duchovny in Zoolander

“You Serious? I Just Told You That A Moment Ago" (Zoolander)

In a hilarious moment from Zoolander, the dim-witted title character (played by star and director Ben Stiller) has to ask disgraced hand model, J.P. Prewitt (David Duchovny) why male models are used in assassination plots twice. In an oral history about the 2001 comedy by Vanity Fair, Duchovny recalls improvising his character’s somewhat irritated response to Derek Zoolander’s repeated question.

Bill Murray in Caddyshack

"... Cinderella Story..." (Caddyshack)

One of the funniest quotes from Caddyshack is an extensive monologue by Bill Murray as greenskeeper Carl Speckler, narrating his own pro golf fantasy. According to Golf.com, no dialogue was actually written for the now iconic scene that was ad-libbed by the former SNL star on camera.

Leonardo DiCaprio in Titanic

"I'm The King Of The World!" (Titanic)

Easily the most oft-quoted moment from Titanic is when Jack (Leonardo DiCaprio) shouts “I’m the king of the world” — a line that was “made up on the spot.” Director James Cameron revealed in an interview with BBC Radio 1 that, after trying several other lines, he fed the now iconic quote to the future Oscar-winning actor through a walkie-talkie, instructing him to really sell it.

Michael Madsen in Reservoir Dogs

Mr. Blonde's Dance (Reservoir Dogs)

One of the things that makes the torture scene from 1992’s Reservoir Dogs so unsettling is the way Vic “Mr. Blonde” Vega (Michael Madsen) taunts Officer Marvin Nash (Kirk Baltz) with a dance to “Stuck in the Middle with You.” According to THR, Madsen invented his playful moves to the Stealers Wheel song in the moment.

Whoopi Goldberg in Ghost

“Molly, You In Danger, Girl" (Ghost)

In a funny scene from the 1990 romantic horror thriller, Ghost, Sam (Patrick Swayze) asks medium Oda Mae Brown (Whoopi Goldberg) to tell his lover, Molly (Demi Moore), what he says word-for-word, including “Molly, you’re in danger.” According to Variety, it was Goldberg’s idea for her to instead say, “Molly, you in danger, girl.”

Robin Williams in Mrs. Doubtfire

Most Of The Dinner Scene (Mrs. Doubtfire)

Chris Columbus revealed to Yahoo! that the majority of what Robin Williams said during the climactic restaurant scene in Mrs. Doubtfire was off the cuff. The director even admitted that he would put multiple cameras on the actor just to keep up with his rapid-fire process.

"Move The Leg" (Captain America: Civil War)

As co-director Anthony Russo revealed on the commentary track for 2016’s Captain America: Civil War, Tom Holland forgot his blocking during a scene when Peter Parker and Tony Stark (Robert Downey Jr.) discuss his double-life as Spider-Man. This prompted the Iron Man actor to instruct Holland to give him room to sit on the bed but stay in character while doing it.

Leonardo DiCaprio in Django Unchained

Calvin Candie's Bleeding Hand (Django Unchained)

One of the most infamous behind-the-scenes facts about Django Unchained is that Leonardo DiCaprio, as Calvin Candie, actually cut his hand during his racist monologue at the dinner table. However, Broomhilda actor Kerry Washington clarified on The Drew Barrymore Show that the blood he smears on her face was not his own, but faux blood that they decided to incorporate into the scene after the fact.

It just goes to show you that some of the most magical moments in moviemaking are not the ones you plan in advance.
