->''"This isn't a hospital, it's an insane asylum!"''
-->-- '''Maj. "Hot Lips" Houlihan'''

A 1970 comedy film based on [[{{Literature/Mash}} Richard Hooker's novel]], ''M*A*S*H'' was the first major hit for its director, Creator/RobertAltman, and the inspiration for the long-running [[{{Series/Mash}} television series]] a few years later.

In the midst of the UsefulNotes/KoreanWar, the 4077th Mobile Army Surgical Hospital is tasked with fixing up the wounded. Two draftee surgeons, "Hawkeye" Pierce (Creator/DonaldSutherland) and "Duke" Forrest (Tom Skerritt), arrive on the scene. Defying all conventions, they join with fellow surgeon "Trapper John" [=McIntyre=] (Elliott Gould) to "fix up" the mood in the hospital with their brand of black humor. The plot of the film is made up of various episodes dealing with their escapades in the Hospital.

It's one of a few different Creator/TwentiethCenturyFox films alleged to have been the first pre-recorded videocassette to roll off the assembly line at Creator/MagneticVideo in the fall of 1977.

----
!!This film provides examples of:

* AdaptationDistillation: The film took the novel's main themes, stripped out most of the [[ValuesDissonance uglier parts]], and came up with this.
* AllAsiansLookAlike: Enforced as the result of an editing decision. The original plan was to simplify the Ho-Jon getting drafted, wounded, treated at the 4077 and ending up working in the Swamp again with him dying on the operating table. When the O.R. scene was moved to before Ho-Jon got drafted, it being Ho-Jon had to be dropped and dialog was changed to the man being a [=POW=], but they left in shots where you can clearly see that it's Ho-Jon on the table.
* TheAllegedCar: "Goddamn Army Jeep!"
* AlliterativeName: Painless Pole's real name is Walter Waldowski.
* AngryBlackMan: The motor pool sergeant in the opening scene.
* AttendingYourOwnFuneral: The unit dentist, "Painless Pole", [[spoiler:wanted to commit suicide, so they set up a mock funeral for him so he could take cyanide and die in a casket. The cyanide pills were fake, and the only dying he did was [[GoodPeopleHaveGoodSex in the Shakespearean sense]]]].
* BadassMustache: Worn by Trapper John.
* BaldOfAwesome: General Hammond sports this look.
* BerserkButton: "Would you say that she was a moaner, Frank?"
* BigGame: The football game between the 4077th and the 325th Evac hospital, which dominates the last third of the film.
* BiggerIsBetterInBed: "Painless Pole" is the "best-equipped" dentist in the army. After Lt. Dish spends the night with him, she is still in a daze the next morning.
* {{Blackmail}}: When Col. Merrill breaks in on Hawkeye, Trapper, and Me Lay performing unauthorized surgery on an American-Japanese infant, they anesthetize him and take compromising photos of him in bed with a prostitute to keep him from talking.
* BookEnds / BrickJoke: Hawkeye and Duke steal a jeep at the beginning of the film to drive from the depot to the 4077th. At the end of the film, they re-steal the same jeep to go back.
** Hawkeye does his whistle in the opening scene, while Radar does it in the end scene.
* BreakTheHaughty: Hawkeye, Trapper and Duke do this to Hot Lips.
* BreakingTheFourthWall: "Attention. Tonight's movie has been ''M*A*S*H''..."
* CatchPhrase: As in the book, Hawkeye's is "finest kind". Save for one or two occasions, this really didn't carry over to the TV show.
** Also, that little whistle that Hawkeye keeps doing. (Which showed up again in ''WesternAnimation/FantasticMrFox''.)
* ChekhovsSkill: We learn early on that Hawkeye and Trapper played football in college, which comes in very handy later.
* ClosestThingWeGot: In one O.R. scene, Hawkeye has his finger pressed against a wounded soldier's carotid artery to stop the fountain of blood, and asks the only unoccupied person in the O.R. to help him with a more enduring solution to the bleeding. Said unoccupied person turns out to be Father Mulcahy, who warns at the outset that this is hardly his area of expertise.
* CompositeCharacter: Frank Burns from the movie is a cross between the Frank Burns from the novel (in which he's a Captain instead of a Major) and another character from the novel named Major Jonathan Hobson, a religious zealot who lived in the Swamp with Hawkeye and Duke before they got him thrown out for praying too much.
* CoolShades: Hawkeye wears tinted glasses (although they do appear to also be prescription lenses) along with a NiceHat. Trapper is shown wearing actual sunglasses in a couple scenes.
* CrazyPrepared: Trapper has just arrived in the camp and is offered a martini, but balks at drinking it without an olive. After he's told that olives are difficult to procure in a war zone, he pulls out a huge jar of them that he just happened to have in his coat pocket, while Duke and Hawkeye stare in amazement.
* CreditsGag: The film ends with the camp P.A. announcer BreakingTheFourthWall by telling us that "tonight's movie has been ''M*A*S*H''", and reading off the names of the cast.
* DefeatByModesty: Hawkeye and Trapper's way of getting Hot Lips to stop being such a pain.
* DontCallMeSir: Hawkeye corrects anyone who calls him Captain Pierce.
* DuelingMovies: Released the same year as that other anti-war satire movie, ''Film/CatchTwentyTwo''.
* DumbBlonde: Hot Lips becomes this later in the movie somehow after sleeping with Duke.
* EmbarrassingNickname: Hot Lips, Spearchucker, Dago Red, Ugly John, Me-Lay...
** Then there's Trapper John, who acquired that nickname after being caught "finding fulfillment" with a coed [[MakingLoveInAllTheWrongPlaces in the ladies' restroom of a Boston & Maine railroad car]], and the young woman in question accusing him of having "trapped" her.
** "Painless Pole" could be taken to refer to Capt. Waldowski's status as a dentist and his ethnicity. Or it could be taken to refer to [[DoubleEntendre something else entirely]].
--->'''Ho-Jon:''' Here he comes! The Jawbreaker!
** Averted/subverted in that none of these characters (apart from Hot Lips) really mind their nicknames; if anything, they ''embrace'' them.
* EveryoneWentToSchoolTogether: Hawkeye knows Trapper John looks familiar then finally recognizes him as a quarterback he played against in his college football days. Later they happen to bump into Hawkeye's boyhood chum Me Lay Marston at the Army hospital in Japan.
* {{Expy}}: Apart from a few mentions of them being in Korea, the sets, costumes and props are clearly meant to evoke TheVietnamWar which was ongoing at the time. This was intentional.
* FakeAssistedSuicide: "Painless Pole" becomes suicidal after discovering he is impotent. His comrades arrange an elaborate [[AttendingYourOwnFuneral living funeral]] for him, capped off by a putative suicide pill -- but instead of dying he wakes up in bed beside a willing nurse, who [[IntimatePsychotherapy cures his affliction]].
* TheFilmOfTheBook
* GettingCrapPastTheRadar: One of the cheers Hot Lips and the other cheerleaders do is "69 is divine". There is a player on their team with that number, but still...
* HalfwayPlotSwitch: Suddenly becomes a football movie for some reason in the last half-hour. One might ask where they got a full football field, plus actual uniforms in Korea; the answer is, one of the Generals had a major thing for running inter-unit football games, and had done it the year before as well.
* HawaiianShirtedTourist: Trapper John wears a Hawaiian shirt in several scenes.
* HiMom: While on R&R in Seoul, Hawkeye is filmed by a newsreel camerawoman, who invites him to say hello to his mother back home. He tells her his mother's deceased, then asks to say hello to his dad instead.
** According to Donald Sutherland, when his parents saw this film for the first time and they got to this scene, his father stood right up in the theater and shouted, "Hi, Donny!" back at the screen.
* HolierThanThou: Frank Burns is this as well as a {{hypocrite}}.
* IfYouDieICallYourStuff: When Painless Pole announces his intention to commit suicide, Bandini asks if he can have his record player.
* ImagineSpot: Toward the end when Hawkeye comes into the O.R. to tell him they've got their orders to go home, Duke has a quick flash of himself emerging from a plane back in the States and being greeted by his wife and kids.[[note]] In the original version of the script, the final scenes showed both Duke and Hawkeye being met by their wives and children in their respective home states.[[/note]]
* InitialismTitle: Short for "Mobile Army Surgical Hospital".
* IntimatePsychotherapy: Hawkeye convinces Dish to "cure" Painless Pole in this manner.
* InvulnerableKnuckles: Averted. When Trapper punches Frank Burns in the face, he appears to be in as much if not more pain than Burns.
* KickTheDog: Frank Burns brings the young Private Boone to tears by telling him that his bringing the wrong needle caused a patient's death, even though the patient died before Boone could have brought it.
* LastSupperSteal: Painless's "last supper" looks very much like [=DaVinci=]'s original.
* LoadsAndLoadsOfCharacters: Including about a dozen major ones.
* TheLoinsSleepTonight: What convinces Painless Pole that he's a "latent homosexual".
* MeaningfulBackgroundEvent: While the surgeons are playing poker toward the end of the film, we see a jeep rolling past the tent bearing a corpse covered in a white sheet. This was originally part of a (deleted) subplot involving Ho-Jon getting wounded in action and then dying in surgery.
* MistakenForServant: Due to Hawkeye using his rank insignia to pin a busted zipper on his bags in the opening scene, Duke assumes that he's the driver to get him to the 4077th. Hawkeye doesn't bother to correct him until they have arrived and are eating and Col. Blake asks about the "stolen jeep".
** Later, as Radar is moving Hawkeye and Duke into the Swamp, Vollmer stops to question his "billeting these enlisted men in the officers' area", then gives an embarrassed salute when corrected.
* NakedFreakOut: Hot Lips has one of these, as part of the process of her [[BreakTheHaughty haughty being broken]]. As far as everyone else involved in the incident is concerned, it's just NakedPeopleAreFunny combined with PassThePopcorn.
* NarrativeProfanityFilter: In-universe, when Blake spots Hawkeye and Frank talking in the mess tent (after Frank's lovemaking with Hot Lips has been broadcast to the whole camp) and asks Radar to tell him what they're saying.
-->'''Hawkeye:''' Does that big ass of hers move around a lot, Frank, or does it sort of lie there flaccid? What would you say about that?
-->'''Radar:''' Um... Hawkeye's questioning the Major on a point of anatomy.
* NeverMyFault: As Duke says of Frank Burns, "Every time a patient croaks on him he says it's God's will or somebody else's fault."
* NoodleIncident: More of a Noodle Insult. One of the opposing players in the football game calls a (black) MASH player a "coon", trying to invite an attack to get him thrown out of the game. Spearchucker tells him the name of the guy's sister and tells him "Use it!". The guy walks up to the line, and we don't hear anything but the normal background noise of the game, but the opponent suddenly lunges at the MASH player and chases him all over the field.
* OfficeGolf: Hawkeye and Trapper play an impromptu game of this in Col. Merrill's office.
* OOCIsSeriousBusiness: To indicate to Hawkeye how seriously depressed Painless Pole is, Father Mulcahy mentions that Painless had told him that poker was "only a game".
* PrecisionFStrike: During the football game, Painless Pole tells an opposing player, "All right, bud, your fuckin' head is comin' right off!" The line (an ad-lib by actor John Schuck) was the first use of the F-word in a major American studio film.
** "Goddamn Army!"
* PresentDayPast: Korea ca. 1950 looks and feels a helluva lot like [[VietnamWar Vietnam]] ca. 1970. Once again, [[WordOfGod this was entirely intentional on Altman's part]].
* RandomEventsPlot: The film, rather than following a coherent narrative, is more of a series of episodes depicting a year in the life of the 4077th. For the most part, once a major subplot -- Painless Pole's "suicide", Hawkeye and Trapper's Japan trip, the football game -- is wrapped up, its effect on the rest of the "story" is minimal.
** If anything, the novel is even ''more'' random and unstructured, and it's a testament to Ring Lardner Jr that he managed to [[AdaptationDistillation distill it]] into something that at least had some slight organization.
* RedOniBlueOni: In the football game the serious ringer-filled 325th Evac team wears blue jerseys and the more boisterous 4077th wears red.
* RhymingWithItself: The verses of "Suicide is Painless" follow an AAAA rhyme scheme, but the first and last verses both have the same word at the end of lines 1 and 4 ("see" and "me" respectively).
* RunningGag: The camp's bumbling P.A. announcer.
* ShoeShineMister: Snippets of the song "Tokyo Shoe Shine Boy" are played at various times. The song (an actual tune from 1951, which was also included on the soundtrack album to the movie) is sung in Japanese, except for the words "Tokyo Shoe Shine Boy" in English.
* SoundtrackDissonance: It opens with an angsty folk song playing over scenes of wounded soldiers arriving by helicopters, and the other songs in the film also provide an ironic counterpoint to what's happening on screen, as well as the goofy loudspeaker announcements.
* SourceMusic: Several tunes, either instrumental or sung in Japanese, are played over the P.A. throughout the film.
* SouthernFriedPrivate: Duke is kind of this, though he's actually a captain.
* SpitefulSpit: One of the 325th Evac's football players spits a stream of water into Radar's ear in the locker room.
* SuicideIsPainless: The theme song is the TropeNamer. ItMakesSenseInContext.
* ThemeTuneCameo: During the "funeral" for Painless Pole.
* UnsympatheticComedyProtagonist: Despite being the film's {{Designated Hero}}es, Hawkeye, Trapper and company are this through and through. If you root for them at all it's only because their antagonists are even bigger {{Jerkass}}es than they are.
* WackyFratboyHijinx: Or the military equivalent thereof.
* YouWouldntHitAGuyWithGlasses: Invoked by Hawkeye after he baits Frank Burns into attacking him in the mess tent.
* YourCheatingHeart: Pretty much every married character in the film has something going on the side. (Including Hawkeye, who in contrast to the series has a wife and kids.)
