Mood Whiplash/Film

"Lilo: (to Stitch, bitterly) You ruined everything. (Stitch exposes his antennae, spikes, and extra arms) Lilo: You're one of them? (shoves Stitch into the ground) Get outta here, Stitch."
 * Disney movies, especially of the Disney Animated Canon or Pixar variety, tend to have a considerable amount of this.
 * Pixar, especially in recent years, often applies this trope, and are able to pull it off well, more importantly. Case in Point: WALL-E, Up, and Toy Story 3
 * Examples from Toy Story 3 include Lotso upon Buzz calling himself and his friends a family, or Lotso, or as referenced by the page quotation, the talking telephone describing the nature of Sunnyside.
 * At the end of WALL-E, try immediately restarting the movie. What were Amusing Injuries two hours ago are now Dude, Not Funny.
 * Up has a cutesy musical montage showing Carl and Ellie after their marriage, with the two doing heartwarming activities together, like building their house out of the abandoned one they met in and saving up to travel to Paradise Falls, but during this montage, we also see
 * Then, for further whiplash, right after this tragic image fades away, we see another, purely comedic Musical Montage set to Habanerna from Carmen of Carl getting up in the morning, complete with an Overly Long Gag involving a stairlift.
 * Also, there's another scene that begins with Carl and Russel having dinner with . It ends with  . Also, all of this is in a kids' movie.
 * Bambi. The movie goes from Bambi finding out his mom is dead in the winter to SINGING BIRDS AND UPBEAT MUSIC IN THE SPRING!
 * Who Framed Roger Rabbit? contains what must be a pitch-perfect parody; all throughout the movie, Eddie Valiant has been haunted by what happened to him and his brother in Toontown, and towards the end he has to return there for the first time in years. He has to work up his courage and engage in a long, tense drive through a seemingly never-ending tunnel, with the music and moment increasingly tense, as if there was something very, very sinister waiting at the other end... only for a curtain to lift at the end of the tunnel with a brightly coloured cartoon paradise on the other side with hundreds of happy cartoon animals cheerfully singing "Smile, Darn Ya, Smile!" and cartoon bluebirds flying around his head chirping "Hiya Eddie!"
 * Oliver and Company has a wide variety of Mood Whiplash moments, but it's especially noteworthy that even in the first few minutes of the movie, it goes from a pleasant scene involving a bunch of cats being adopted from a box during daytime, to Oliver being all alone in said box at night, while the rain is washing it away and he is left out in the rain, trying to make his way around and being chased by vicious dogs. What's interesting about this transition is that the same song, "Once Upon A Time In New York City" is playing throughout said intro sequence, and sounds pleasant in the former part and unpleasant in the latter part, without a significant change in melody.
 * The Disney version of The Hunchback of Notre Dame yet. A dramatic sequence is immediately followed by the comic musical number "A Guy Like You", which undermines the effect of both scenes.
 * And then it's promptly followed by another fairly serious scene (though far lower-key than the previous dramatic sequence).
 * Heaven's Light/Hellfire. That is all.
 * The Festival of Fools scene is probably Disney's most guilty example of this, if not the most guilty example of all time. First, it starts off comical and whimsical. Then it becomes potentially sad, but then back to comical- then suddenly it turns horrific and tearjerking, but then it goes to heartwarming and pure, then to kind of actiony, then back to comical, and then finally to relentlessly depressing. All in one goddamned scene.
 * Mulan goes from a happy go lucky (if slightly sexist) Disney Song to the devastation of war in less than one second. The mood literally changes mid-verse.
 * To be fair, that was entirely intentional. The contrast was emphasized in order to to make the destruction that much more heartbreaking.
 * and also to emphasize that the soldiers were being somewhat shallow and thoughtless at the time.
 * To name one example from Lilo and Stitch, one scene features a hilarious slapstick fight between Jumba and Stitch involving use of a Volkswagen Beetle as a blunt instrument, the immortal line "Oh, good! My dog found the chainsaw!", and hot-potato with an overloaded plasma gun. The very next scene has Nani and Lilo's house blown to kingdom come, Cobra Bubbles chewing Nani out for her failures as a parent figure and trying to take Lilo away, and Lilo angrily blaming Stitch for ruining everything. Ouch.
 * To name one example from Lilo and Stitch, one scene features a hilarious slapstick fight between Jumba and Stitch involving use of a Volkswagen Beetle as a blunt instrument, the immortal line "Oh, good!

Ouch.

"Johnny: ''"I did not hit her! It's not true, it's bullshit! I did not hit her! I did not!... oh hi Mark."
 * Another example occurs earlier on when a short struggle between Stitch, Jumba and Pleakely ends with Pleakely and Jumba bouncing away on the ocean like a skipping stone. A few seconds beforehand, Stitch had almost dragged Lilo to the bottom of the ocean with him, and when we cut back to Lilo, Nani, David and Bubbles, they're all just about as happy as you'd expect.
 * After the lovely duet between Flynn and Rapunzel in Tangled where they had their Almost Kiss, Flynn sees the Stabbington brothers and the atmosphere visibly darkens.
 * In-story, after Rapunzel has left the tower for the first time, she continually switches from being happy to depressed. "I'm free!"/"Mother is going to kill me..."/"This is the best day of my life!"/"I'm the worst daughter ever!"
 * In the scene where Rapunzel first asks Mother Gothel to take her to see the lanterns, the conversation goes abruptly between relatively playful banter and deeply disturbing emotional manipulation on Mother Gothel's part.
 * In the scene where Rapunzel has Flynn tied to the chair, Flynn starts using Antiquated Linguistics to cheesy pickup lines in the span of one sentence. It's like the scene shifted from something out of Shakespeare to Joey from Friends. And it's Actually Pretty Funny.
 * The Courtship ceremony from Dinosaur (which involves lemurs participating in a merrymaking ritual so they can find mates) ends with a meteorite hitting Earth.
 * The filme version of Horton Hears a Who has a couple examples of this in one scene. The feeling of relief from having escaped Vlad in a previous scene vanishes when he shows up again, this time even more detemined to destroy the clover. The following chase scene is pretty tense, but it still manages to fit in a couple of gags, such as Horton plowing through a snowcapped mountain and expelling the snow like a steam train, and complaining about "brainfreeze" afterwards. About a minute after this happens, Vlad drops the clover off an enormous cliff. Things get more than a little sad after that, a mood that persists for several minutes before another joke heavy scene.
 * Just when Alice decides she's had enough of Wonderland, she spots a path that might take her home. She happily runs down it, the music brightens up, and it looks like she'll make it home in time for tea...but then a dog sweeps away the rest of the path before her eyes. Alice then sits on a rock and sings a song about how often she fails to heed "very good advice", which climaxes into her and the surrounding animals breaking into tears.
 * The Lion King 2: Simba's Pride features a hopeful, uplifting musical number about how the animal world is one big family supporting each other. Then it switches to a vicious Villain Song where the Big Bad sings about how she Loves the Sound of Screaming.
 * Something Wild, and HOW. The first half of Jonathan Demme's film is a kooky sexcapade, but when raven-haired Lulu turns into golden-haired Audrey, that's when the tone changes - enter Ray Liotta.
 * Saving Private Ryan intermixes thrilling battle scenes with thoughtful scenes featuring rookie soldiers breaking down in tears after realizing the horror they've gotten themselves into, while the more veteran soldiers start pondering about the purpose of war.
 * Don't forget the soldiers telling funny stories before the final battle.
 * Most chilling when Mellish, a Jew, is handed a Hitler Youth knife. He cracks a joke that it is now a Shabbat Challah cutter (for cutting the bread in the Jewish observance of Shabbat), and then immediately breaks down in tears.
 * Hancock started out comedically with the superhero John Hancock being an alcoholic crimefighter who causes mass amounts of destruction through his bad habits. The film begins to get more and more serious as it continues, culminating in Thankfully, the mood shifts back to bittersweet as the film ends.
 * The 1960 movie Where the Boys Are starts out as a frothy Annette Funicello-style beach comedy and climaxes with the rape and attempted suicide of one of the leads.
 * The Great Escape starts off as a cheerful, fun escape romp. Until the part when . Yikes.
 * On top of that, Steve McQueen's escape goes from exciting and action packed,
 * Of all places, The Passion of the Christ. During a flashback in between the movie's extended torture scenes, it shows Mary asking Jesus about a table he's building. She comments, with a smile, that It Will Never Catch On.
 * Misery: Annie Wilkes. Dear Lord, Annie Wilkes.
 * Little Shop of Horrors is considered a "hothouse of laughs" by Gene Siskel. True, the movie is pretty funny at times, from Seymour's interview at a radio station to Orin dealing with the only patient that can withstand the pain. However, once, we're treated to more serious parts of the story, starting with a heartwarming/tearjerking musical number where Seymour comforts Audrey over
 * And this is even WITH a last-minute Focus Group Ending slapped on. Had it been made as intended,
 * During their initial theatrical releases in Japan, the Studio Ghibli films My Neighbour Totoro and Grave of the Fireflies were shown together as a double feature. With the former being a warm-hearted, whimsical tale, and the latter being a devastating look at the horrors of war, this naturally caused some discord within audiences. Not surprising when you consider, the double feature was marketed at parents and their children.
 * Superman Returns is similar -- in the middle of a relatively light-hearted movie, there's the truly uncomfortable scene where Lex Luthor and his goons kick the crap out of Superman. And to top it off, Lex stabs Supes in the back with a Kryptonite shiv. Compared to the rest of the movie, it's unsettlingly brutal. Don't forget the unsettling scene where a thug with a skull tattoo on the back of his head plays a duet with Lois's son on the piano before assaulting and preparing to kill Lois in front of him. Lois's son kills the thug with the piano.
 * Kung Fu Hustle. The scene that starts the whole Axe Gang versus the Tenants debacle begins with Sing getting his ass handed to him by the tenants and the landlady, accidentally attracting the attention of the Axe Gang with a misplaced flare ("Who threw that firecracker?"), and the Landlady comically fleeing at what got Sing's ass handed to him (calling the Landlady fat). There is a brutal fight scene, interspersed with Brother Sum hitting his Assistant comedically. A Looney Tunes tribute ends with a dramatic/funny scene of Sing (with his lips swollen from snake bites) in a fit of rage.
 * Shaolin Soccer also contains a lot of silly slapstick comedy. One scene, however, dwells on a scrawny soccer player bursting into tears as maudlin music swells in the background.
 * Done brilliantly in the film adaptation of A Prairie Home Companion when during the titular radio show a heartbreaking duet "Goodbye to my Mama" is followed up immediately by a pair of goofy cowboys singing "Bad Jokes", 4 1/2 minutes of pure, unadulterated Crowning Moment of Funny.
 * The Serbian epic The Underground mixes a comic farce with the horrors of World War II and the tragedy of Balkanization.
 * Most Bosnian/Serbian/Croatian movies fall into this trope, since it is what happens when you combine the joival humor of the region and it's tragic past.
 * The Last American Virgin starts off as a teen comedy with situations on par with American Pie. In the last third of the movie, The movie ends with a party after Spring Break where the main character sees his old friends after staying behind for the vacation. He walks into the party and sees  Considering the type of movie most thought it was, it had quite the Downer Ending in the form of a Kick the Dog Moment.
 * Shaun of the Dead uses this trope, flipping between a mad-cap comedy and an earnest disaster movie with plenty of high tragedy played straight.
 * Perfect example:
 * Even Better Example:
 * Even better example still:
 * Joseph King of Dreams goes from Joesph singing on top of a hill about his general awesomeness, to being locked in a cell with a tree for company.
 * The 1984 Chinese movie Fantasy Mission Force, helpfully recapped here by The Agony Booth crew. The movie starts out as crazy low-brow slapstick "humor", with plot twists that make no sense, and then suddenly there are people being bloodily massacred on-screen, including most of the main characters. What? You can't blame all that on the American dub, or on some cultural humor thing. But don't take my word for it.
 * La Vita è bella (Life is Beautiful), starts out as a comedy in Mussolini's Italy, and ends up as a comedy in a concentration camp. See also Genre Shift.
 * By the time the credits roll in, the viewer doesn't know whether to go "Awwwwwww !" or shoot himself in the head. It's like Real Life that way.
 * And don't forget the comedy Burn After Reading. We start at casual, there are some laugh-out-loud moments, some tense scenes, followed by some shockingly funny scenes or shockingly sad scenes or merely absurd scenes. After all, every single character is absurdly stupid.
 * Except Tilda Swinton. She's a cold bitch.
 * And the two CIA officers. And the Russians.
 * The scene where  deserves a special mention for turning the most tragic part in the entire movie into one of the funniest in under a second with the scene change. I witnessed the entire cinema crack up in simultaneous laughter at this utterly genius transition.
 * Melanie in Jackie Brown taunts Lewis for not knowing where he parked the car. Lewis warns her not to say another word and the scene keeps its light-hearted atmosphere
 * Pulp Fiction has Christopher Walken's character solemnly explaining how the gold watch was handed down through World War I and World War II... and The Vietnam War, where he and Butch's father saved it from being confiscated by.
 * Click starts off as a typical Adam Sandler flick. Fart jokes, Rob Schneider cameos, and Jerkass moments ahoy! However,
 * In the James Bond film Quantum of Solace, there is a genuine, touching Tear Jerker moment between and Bond when . Then, several seconds later, Bond dumps his body into a dumpster and loots his wallet, pointing that "he wouldn't care". The audience wasn't sure whether to laugh or not.
 * Another Bond example: On Her Majesty's Secret Service has newlyweds Bond and Tracy drive off happily. Bond pauses to get rid of the flowers and whatnot on the car. Then Blofeld and Irma Bunt drive up to them and fire several shots at them. Bond survives. Guess who doesn't?
 * And another Bond example: In For Your Eyes Only, Bond has a baddie trapped in a car slowly sliding off a cliff. Bond takes out a pin and says "You left this with Ferrara, I believe", tossing it over to the baddie. He can only stare at the pin as the car starts sliding off some more before Bond kicks the car off himself. This badass moment is immediately ruined by Bond noting "He had no head for heights...".
 * Serenity: "I am a leaf on the wind. Watch how I "
 * In Ghosts of the Abyss, an IMAX film by James Cameron detailing his return to the Titanic, one of his two probes loses power while inside a stateroom. After almost losing the other probe in a rescue effort, Cameron's team gets both back outside the ship to the tune of "Just The Two of Us." It's the CMOH of the film. Then, as the submersibles are returning to the surface, the camera cuts to a crewman in one of the submersibles who reports the time as
 * The Land Before Time goes from the death of Little Foot's mother to a scene in which a bunch of baby flying pterosaurs (including Petrie) fight over a cherry, complete with catchy music in the background. Of course it goes back to Little Foot and his sorrow soon enough, but still.
 * Pretty much most Don Bluth movies are like this. Take An American Tail for example. Heck, the "No Cats in America" song actually switches moods within the verses. Repeatedly.
 * The Graduate is a satirical comedy up until the scene where Elaine discovers the truth about her mother and Ben. Things get considerably heavier then.
 * The Boys in the Band starts out as a comedy and ends as a Tear Jerker, with plenty of yoyoing between "hilarious" and "depressing" in the middle.
 * Being a pitch black comedy, In Bruges does this expertly with some frequency.
 * Tyler Perry. His most recent film, Madea Goes to Jail, is the best example of this as the plot frequently switches focus from the comical, over-the-top Madea getting into trouble in amusing ways, to a young prostitute's trials and tribulations that are handled in a dead serious manner. It's enough to give you...oh, you know.
 * Mrs. Doubtfire was adverted as a wacky romp, which it was, except for the scenes where Robin Williams and Sally Field were tearing each other apart, sometimes in front of their kids.
 * The new Star Trek movie has a killer instance of this. It's a tense, horrible scene that has everyone on the bridge in shock... except newly-arrived Scotty, who proclaims, "I LIKE THIS SHIP! It's exciting!"
 * JCVD varies between scenes of a police chief and a doctor being forced to walk through a crowd of onlookers cheering Jean-Claude Van Damme, who they believe to be in the process of robbing their post office (it was his home town, so he was still an icon), and court room scenes of his custody battle over his daughter.
 * The Taiwanese horror film Re-Cycle hopscotches around moods like a meth-crazed grasshopper. Starting off as a suspense-driven horror film, about midway through the horror gives way to dark fantasy followed by Squick in the form of  and then a few genuinely touching moments, a brief return to horror, and then a Bittersweet Ending sandwiched in between TWO separate Mind Screws. Add a couple of Ass Pulls--because what else can you call  ??--and you're there.
 * The final third of North doesn't just involve the youthful hero trying to return to his parents -- another kid, his conniving, power-hungry friend from back home, has sent assassins out to kill him. The film has been a light fantasy up to this point, and indeed continues to be, but the plot development is so dark that it invokes this trope nevertheless.
 * Incident at Loch Ness is a documentary  about director Werner Herzog attempting to film a project about the Loch Ness monster and the nature of folk tales. Herzog has to deal with the undercutting of assistant-director Zak Penn constantly. Penn is trying to stage things for dramatic effect, such as getting an animatronic Nessie to scare the crew members, much to Herzog's consternation. Then, after Zak Penn draws a gun,   and all hell breaks loose.
 * In Harry Potter and the Goblet of Fire After Harry apparates back to
 * There's an earlier example of this in the same film, when Mad-Eye Moody is demonstrating the Unforgiveable Curses. Making the little spidery thing dance and jump and crawl over people? Classroom is in fits of giggles. Making her jump out of the window or drown herself? Hilarity comes ot a screeching halt. See it here.
 * In the Harry Potter book, the scene with Ron's humorous love potion antics already has an extreme case of this, but the movie takes it a step further by having Ron comically toppling out of frame first. The audience giggles. Cut immediately to him convulsing on the floor and foaming at the mouth.
 * In the same film, there's the scene where Hagrid and Slughorn are singing that wizard song and reminiscing about Aragog. In a drunken stupor, complete with Hagrid passing out after Slughorn mentions he once had a fish.
 * Jaws manages to successfully switch back and forth between comedy and horror, sometimes in the space of a single line: "Come down here and chum some of this shit!"
 * Spielberg admitted that in that scene, the intention was laugh - Jump Scare - nervous laugh ("You're gonna need a bigger boat"). So much that when after a preview had the one-liner being covered by screams, they re-edited so the audience could recover and properly laugh.
 * 9|Nine example: the Fabrication Machine's factory has just exploded violently, the dolls are rejoicing, the twins are playing a recording of Over the Rainbow--and then  while Over the Rainbow continues to play.
 * Minor example in the 1946 Cole Porter biopic Night and Day: at one point you get Busby Berkeley-type numbers intercut with scenes of Porter on the operating table getting major leg surgery after his riding accident.
 * V for Vendetta, Gordon's hysterically funny TV show and then BOOM
 * Gold Diggers of 1933 ends with a happy scene of all the lovers finally ending up together, followed by a somber Depression-themed musical number that closes the film. (Had it not been for Executive Meddling, the film would have ended with a happier song, which instead got pushed to the middle of the film.)
 * Zombieland. The  crosses the line between funny and sad so many times it uses said line as a jump-rope.
 * Also, the scene where it's revealed that  is appallingly sad and actually made this troper get teary-eyed in a damn zombie comedy.
 * The whiplash at this part actually comes when said character then says 'I haven't cried this hard since Titanic!'
 * After which he wipes his eyes with hundred-dollar bills.
 * Though the use of this trope is a longtime staple in Coen brothers films (see Burn After Reading above), probably the most extreme example is in Fargo, in which hilarious deadpan comedy is interspersed with graphic killings, brutal violence, and a surprisingly haunting musical theme. The sheer extremity of the film's Mood Whiplash is personified in the character of Gaear (played by Peter Stormare), who rarely speaks except to nag Steve Buscemi's character (repeatedly) about going to "the pancakes house", tears up over TV soap operas - and is a terrifying, cold-blooded killer who murders anyone and everyone who gets in his way (including ) without a moment's hesitation.
 * An intentional use: the beginning of Lemony Snicket's A Series of Unfortunate Events features an animated short called "The Littlest Elf"... followed by Jude Law's grim narration.
 * In Bob Fosse's film version of Cabaret, at a picnic a rather handsome German youth begins singing the patriotic song "Tomorrow Belongs To Me", and other people begin to spontaneously join him acapella. Then the camera pans back, to reveal him wearing the Swastika armband and a brownshirt.
 * The fairly good Irish indie film "WC", has a Clerks-ish vibe for the most part... then we flash back to Katya's horrible kidnapping and rape shot in a distressingly realistic way... then we go right back into the low-key comedy Clerks-ish style.
 * Averted in Clerks, a straight comedy that was originally going to end with the main character suddenly getting gunned down in a robbery. Kevin Smith was apparently brought to his senses.
 * One scene in All Dogs Go to Heaven 2 features David, a runaway boy with a knack for magic tricks, with Charlie, Itchy and Sasha (Charlie's love interest) singing a bright cheerful song about life on "Easy Street" at a center filled with other performers. However, when David screws up at one point and falls into the fountain, the other folks leave, and then song almost instantly changes to a Tear Jerker. (Not to mention that scene starts out bright and sunny and next thing you know it's pouring with rain).
 * In The Lost Battalion, the main characters are saved by their side's artillery, complete with heartwarming music and cheering. In an instant, this turns sour as the artillery has been misaimed and is falling right on top of them, killing tons of soldiers.
 * Mr. Magorium's Wonder Emporium is a very musical, colourful, and exciting film until it begins winding down to . Granted, one of the movie's lessons is about how to rise from tragedy and find your own place, but the shift from whimsical to bleakly serious is fairly shocking for a children's movie.
 * The Star Wars movies do this. Going by order of release, the first movie was a light-hearted fairy tale, the second movie was a dark and serious drama, and the third flipped back to being a child friendly light hearted action movie with even more whimsical creatures and humour. This tone carried through the fourth and fifth movies before going back to the dark drama and even more grittiness that bordered on disturbing.
 * The climax of The Phantom Menace was pointed out by the editor to do this, in a negative way. Due to it being made up of four different conflicts with varying tones, it jumps between sadness at the death of a hero, humour with Jar-Jar Binks, excitement in a large space battle, and nothing in a scene with Padme. This results in all the would-be emotions being negated and in a worse case scenario leaving the audience bored out of their minds. Both the following movies had much less complicated climaxes as a result.
 * The second and third prequel movies do a better job at keeping the same general mood throughout except for the climax of Revenge of the Sith. Anakin is disfigured and has turned to the Dark Side, Padme is dead, the Jedi Order and the Republic are no more, Palpatine has taken over the galaxy,... and we get a cute little funny scene with C-3PO moments before the end credits.
 * In Sleuth, the story jumps from funny to horrifying within a second. Some scenes you might alternate between smiling and being afraid for the characters' lives several times within one moment. You could even find yourself grinning while thinking "I think something horrible is going to happen any minute".
 * The party scene in Beethoven's 2nd takes a dark turn when Ryce's boyfriend attempts to rape her, then goes back to the usual hijinks when Beethoven causes the boyfriend's vacation home to collapse.
 * In The Good Son when Mark tells Susan that Henry may be a psychopath she slaps him and tells him never to say that again, seconds later she's crying and hugging him. Yay mood swings!
 * CSA: Confederate States of America goes from joking about the Alternate History it's showing to just examining how bad the country is as a result.
 * The 1989 comedy The Burbs on the surface seems to be a wacky "mistaken identity" comedy about three childish protagonists who suspect that their next-door neighbors are serial killers. Hilarity Ensues, and then the whole thing culminates in a Crowning Moment of Funny when the three men accidentally blow up the neighbors' house....or so it seems.  But then, at the very end, the mood reverts to comedy again as the teenaged Nightmare Fuel Station Attendant looks around at the chaos surrounding him and exults, "God, I love this street!"
 * The Rocky Horror Picture Show. It's all spoofy and crazy and fun and then.... WTF!? The song "I'm Going Home" pops up and it's downhill from there.
 * Of course, hacking Eddie to death with an ax right after he's introduced, feeding his corpse to unsuspecting guests, and brainwashing everyone into becoming your personal orgy slaves might have been a bigger whiplash for some people. Also, those seeing it for the first time might have expected a campy horror spoof; after getting up and doing the Time Warp, one might have been a tad shocked to see Tim curry throw off his cape and reveal a bodice and fishnet stockings. What seemed like a Monster Mash in the entire first act briskly becomes something more like Pink Flamingos.
 * The scholar/narrator/storyteller/whoever deserves a mention as well. He starts out giving straightlaced, nonchalant, neutral descriptions of the situation, lets himself go during the Time Warp, goes back to straightlaced, and at the end delivers a slow, deadpan commentary on humanity that sounds almost like an ill omen.
 * Alien 3 had a fair few examples of this, including a hilariously well-timed joke about running with scissors in-between gruesome deaths in the middle of a chase scene,  having his head lopped off less than a minute after , and Morse erroneously yelling "fuck!" after a period of silence following  . Plenty of other examples involving sudden cuts between scenes with vastly different levels of intensity.
 * The little-seen Charlie Chaplin non-Tramp movie Monsieur Verdoux is an interesting version of this: for the first two-thirds it's a merry dark comedy about a dandy who murders a succession of rich wives for their money; there are quite hilarious hijinks as he attempts to kill the most annoying one in a rowboat and also when the current wife shows up at the wedding to the next wife, etc. It then takes a not-funny dark and philosophical turn when  Not so hilarious.
 * The little-seen movie Fierce People is really only notable for this trope. The first half is a jolly, cutesy coming of age/FishOutOfWater movie. Then around the halfway mark the main character, causing him to reevaluate everything he knows. The scene where his mother discovers the... true nature of the crime is particularly brutal because Finn's character is pretty understated up until this point, where he breaks down with shame, begging her not to reveal it. Not surprisingly, the second half of the movie is like a completely different film after that.
 * Korean cinema and Asian movies in general tend to do this a lot. There are already a few examples here but others include:
 * Korean film distributor Showbox has this cute little Vanity Plate preceding all of their movies. This includes dark flicks such as Taegukgi ("Hard to believe﻿ 20 minutes after this adorable logo, you'd see the most intensive, violence war scenes ever.", says a comment in the linked video) and The Host...
 * ...which itself flip flops from a family drama, to a comedy, to a giant monster movie, to a political thriller, and returns to all of these in a moment's notice.
 * The Korean film Save the Green Planet can be described as "Men in Black meets Misery," with all the mood dissonance that implies.
 * The Heroic Trio - A goofy Hong Kong superhero/martial arts movie about three women kicking butt. There are scenes of pure slapstick mingled with decapitations, blood sprays, and babies being killed.
 * The Untold Story (aka Bun Man) - A supposedly true story about a man from Macau who kills people and cooks them in his dumplings. The film is extremely dark and disturbing except for the scenes taking place at the police station which are on an almost sitcom-level of whackiness.
 * The Korean movie Vampire Cop Ricky, nominally a comedy, switches repeatedly between serious cop drama and total vampire slapstick. Several serious scenes are interrupted by sudden physical comedy, while others start hilarious and end very, very badly.
 * Fellini's Nights of Cabiria varies in tone from comic to somewhat tragic, but with a generally positive outlook. Nothing like the end of the movie where.
 * The Cable Guy: "I can be your best friend, or your worst enemy."
 * One of the best comedic moments in True Lies is probably the "Battery, Aziz" scene - the terrorist Aziz is making an angry and frightening threat video, when the camcorder runs low on battery. The cameraman lowers the camera, looks pained and apologetic, and explains "battery, Aziz!" Aziz, dumbfounded, snaps at him "then go get another one, you IDIOT!"
 * Tron: Legacy gives us the nightclub battle, where we see the flamboyantly and Ambiguously Gay Castor hilariously having a blast with his cane gun. Nano-seconds later, we cut to
 * Averted in Terminator 2: Judgment Day. The reason that the T-800's Un Smile was cut out of the film was because James Cameron thought it was too big of a leap to go from Arnold goofing off, to discussing Judgment Day in the very next scene.
 * In Barney's Version, the first two-thirds are more or less a romantic/sex comedy (albeit a dark, rather mean-spirited one), and then takes a very gloomy turn when It Got Worse. A lot.
 * Twister has one that might be more for a character than the audience. Late in the movie, when the chasers are taking shelter from an approaching F-5 tornado, the high winds cause a hose to break and whip around near the huddling group. One of the characters manages to grab the hose, bellowing a shout of triumph as he holds his prize. A second later a hubcap flies through the air, slicing across his forehead and needless to say darkening his mood.
 * A Very Long Engagement alternates between the often fairly whimsical scenes set in the present and extremely grisly flashbacks to the recently ended first world war.
 * Dagon's slow pacing and dramatic mood is interrupted by a flashback to a surprisingly dramatic depiction of the town's corruption by inhuman forces.
 * The entire film of The Secret of Kells qualifies as this, such as going from scenes of happy forest antics to a scene filled with Nightmare Fuel in a matter of minutes - and sometimes even seconds.
 * Short Circuit II, like its predecessor, is a fairly light comedy. That is, till the scene where Oscar has his goons brutally smash up Johnny Five in near-slow-motion. Seeing him "limp off" afterwards doesn't help matters.
 * And then, it reaches Tear Jerker levels when Johnny Five writes "" on a brick wall.
 * The film version of He's Just Not That Into You falls into this thanks to its Four Lines, All Waiting plot. You switch between peppy, fun romantic comedy to watching a marriage fall apart with no humor at all.
 * The film Super frequently shifts tones from an indie-flavored Superhero Parody to a very Black Comedy with people getting their heads split open with wrenches.
 * The Bollywood megamovie 3 Idiots has an orbital one. Our heroes are fixing a desperate senior's flying camera, to help him to a graduation. The small chooper flies up to the window of the senior, while our heroes are singing and dancing.
 * Black Swan has several, none more jarring than the one Nina herself suffers when she finds herself  with her sleeping mother right next to her.
 * Toward the end of Cabin Fever, the main character is passed out in jail, having a dream about himself and his girlfriend happily skipping through a flowery meadow with happy music. Which then smash-cuts to a shot of her horribly rotted face and loud screaming.
 * One of Johnny's lines from The Room contains this. Granted, it's more to do with the words themselves, as Tommy Wiseau's tone is the same throughout:

 * One of Johnny's lines from The Room contains this. Granted, it's more to do with the words themselves, as Tommy Wiseau's tone is the same throughout:

"- I missed you so much. - I still owe you the solution for those Math questions..."
 * Prince of Egypt at one point went from all the firstborns being dead to Moses' sister singing 'When You Believe'. Dude! all the firstborns are dead, can we cut the showtunes? *sniff*.
 * ...But the Hebrews have just been released from generations of bondage, so you can't blame them for wanting to celebrate their newfound freedom a little, and the "When You Believe" is hardly the peppy musical number the above point makes it seem to be.

 * Averted in Mystery Team, thanks to it being a Black Comedy
 * Kung Fu Panda and its sequel have made an art form out of this. At any point in either movie, you could be laughing, crying, cheering, or any combination of the three.
 * The Russian adaptation of Pippi Longstocking does this a couple of times. One second, the audience, along with half of the characters, is laughing at Pippi's antics, the next second she is asked about her parent and breaks into a total Tear Jerker song, revealing that . And then, "Lets play Hide-and-Seek!"
 * Another Russian film, City of Craftsmen has bloody fight between city inhabitants and invaders, with a very serious scene where  as a climax.

 * Pretty much every Shane Meadows film ever made features one of these. A notable example is This Is England: Shaun is having a great time with his new friends, but when Combo returns from prison, things start to get ugly. A particularly devastating use of this trope is when Milky, stoned with Combo, shares pleasant stories about his family, which cause Combo to get increasingly agitated, racist and then beat the crap out of him.
 * 50/50, in spades. It's a comedy about cancer, which should clue you in. Sequences include: Joseph Gordon-Levitt walking down a hallway filled with empathetic cancer patients, being offered weed by older patients followed by a highly amusing trip down a hallway, and then waking up in the middle of the night and vomiting violently. In that order.
