->''"The Hitchcock picture to end all Hitchcock pictures."''
-->-- '''Ernest Lehman''', screenwriter

A classic 1959 thriller by Creator/AlfredHitchcock, in which an innocent man [[MistakenForSpies mistaken for a spy]] is [[TheChase chased]] halfway across the USA by enemy spies searching for a MacGuffin. Probably best known as being that movie that had a climax on Mount Rushmore or more likely as "the movie where a character is chased by a crop duster," a scene which has often been {{homage}}d.

The film begins with New York advertising executive Roger Thornhill (Creator/CaryGrant) being abducted by [[EvilMinions enemy agents]] working for the master foreign spy Phillip Vandamm (Creator/JamesMason), who is currently masquerading as the diplomat Lester Townsend. Vandamm believes Roger to be an American spy, George Kaplan, who has been tailing Vandamm. When Roger insists he is not the spy, Vandamm orders him killed. His henchmen, led by the sinister Leonard (Martin Landau), decide to [[MakeItLookLikeAnAccident stage a fatal accident]] by pouring a bottle of bourbon down Roger's throat and then placing him at the wheel of a stolen car on a cliffside road.

One car chase later, Roger escapes but is arrested for drunk driving. He takes the skeptical police and his equally skeptical mother (Jessie Royce Landis) to the Townsend mansion where he was abducted, only to find Vandamm gone and the housekeeper, another Vandamm associate, claiming Roger stole the car after getting drunk at a party there.

To clear his name, Roger attempts to find George Kaplan. Accompanied by his mother, he searches Kaplan's vacant room at the Plaza Hotel, where he discovers little other than that Kaplan is a shorter man than he and that seemingly none of the hotel staff have ever met the elusive spy in person. After narrowly escaping another encounter with Vandamm's henchmen, Roger goes to the United Nations, where the real Townsend is giving a speech. Roger, surprised to find that it wasn't Townsend who abducted him, is even more surprised when Townsend's [[TheCorpseStopsHere corpse lands in his arms]]. Now WronglyAccused of ''murder'', Roger flees New York.

After a train journey to Chicago, where Roger meets FemmeFatale Eve Kendall (Eva Marie Saint), and the famous cropduster incident, Roger eventually follows Eve to an auction where Vandamm is bidding on a statue. To escape the spy, Roger disrupts the auction, deliberately getting himself arrested by the police.

The police are ordered to take Roger to the Professor (Leo G. Carroll), an American spymaster, [[MrExposition who explains the plot]]. George Kaplan never existed; he was only a red herring, meant to divert the enemy from the real agent. While Roger's actions initially provided a useful inadvertent distraction, he has ended up raising Vandamm's suspicions towards the real spy, so the Professor proposes a complex charade to resolve the situation.

When this goes wrong, Roger and Eve end up being chased across [[MonumentalBattle Mount Rushmore]] by Leonard and Vandamm's other henchmen.

One of Hitchcock's most popular films, ''North by Northwest'' was a major stylistic influence on ''Series/TheManFromUncle'': in fact, Leo G. Carroll, who played Alexander Waverly in that series, plays a very similar character (sobriquetted "The Professor") in the film, and the TV show drew its "innocent gets caught up in international intrigue" shtick from the film. It has also sometimes been called the first Franchise/JamesBond film.
----
!!This film contains examples of:

* ActionSurvivor: Roger. One poorly-timed summon at a restaurant and he's thrust into a life-threatening conspiracy involving ColdWar espionage.
* AffablyEvil: Vandamm. May be some traces of FauxAffablyEvil in there, too.
* TheAlcoholic: Thornhill himself.
* AllThereInTheManual: Valerian and Licht's names are never stated on-screen but are given in the script.
* AmbiguouslyGay: Leonard. "Call it my woman's intuition."
* ArchEnemy: Phillip Vandamm to Roger O Thornhill.
* ArtifactTitle: Early drafts of the script called for the final showdown to take place in Alaska, but no one could come up with a better replacement title after the climactic scene was changed to Mount Rushmore.
** Actually, ''"North by Northwest"'' doesn't even exist on the compass. The only valid directions similar are ''North by West'', ''Northwest by North'', and ''North-Northwest''.
** Although, at one point, Roger does get on a Northwest Airlines plane, and apparently goes north.
* ArtisticLicenseGeography:
** Roger is seen driving on a treacherous, winding coastal road along cliffs several hundred feet high... in Long Island, New York! While there are some small cliffs in parts of Long Island, there is no scenery or road there anywhere approaching the type of landscape he was driving in, which was clearly modeled after the California coast.
** Though in another scene the movie got it right: when Roger and his secretary are riding in a taxi from his Madison Avenue office to the Plaza Hotel, the view through the taxi's back window is the actual route a vehicle would take between the two locations.
* ArtisticTitle: The [[http://www.artofthetitle.com/title/north-by-northwest/ opening sequence,]] designed by Saul Bass, depicts the credits sliding up and down the side of a Manhattan office building.
* AsYouKnow: The truth about Kaplan is explained incredibly awkwardly by the Professor to the only other people in the world who already know about it.
* {{Auction}}: Roger makes a public nuisance of himself at an art auction (claiming that the paintings were fake, bidding 12 dollars when the highest preceding bid was 1000, etc.) so that the police would arrest him, thus keeping Vandamm from getting his hands on him. It was later revealed that Vandamm used the auction house as a cover to smuggle microfilm out of the country.
* BadassOnPaper: Thornhill is just an ordinary Madison Avenue executive, yet over the course of the film, he manages to survive three attempts made on his life, causes the death of one of the perpetrators and [[spoiler:manages to save Eve from certain death]].
* BetterManhandleTheMurderWeapon: Conveniently, a photographer is present to take an incriminating photo at the exact moment the victim falls on Thornhill not getting what's happening, he pulls the knife out of the victim's back. The look on Roger's face doesn't help, either. Then his guilty-looking mug is plastered on the front page of every newspaper in the country.
* BigApplesauce: The story begins in NYC.
* BigBad: Phillip Vandamm.
* BigFancyHouse: Townsend's Long Island estate. Vandamm's Frank Lloyd Wright-esque house on Mount Rushmore counts, too.
* BlatantLies: Thornhill's explanation to Eve for why the cops are combing the ''20th Century Limited'' for him? Seven unpaid parking tickets.
* {{Bowdlerise}}: Eve's initial conversation with Roger on the train originally included the line, "I never make love on an empty stomach." This was a bit too risqué for the MoralGuardians of the era, who insisted on having it re-dubbed as "I never ''discuss'' love on an empty stomach."
* ButtMonkey: Thornhill is very much this, thanks to Vandamm (who wants him dead) and the police (who want him arrested).
* [[TheCallsAreComingFromInsideTheHouse The Calls Are Coming from Inside the Hotel]]: Thornhill gets a call from the bad guys while casing Kaplan's room at the Plaza. He then finds out from the hotel's switchboard operator that the call came from the lobby.
* CasualDangerDialog: At the climax, Roger and Eve engage in witty banter while dangling by their fingertips from Mt. Rushmore.
* TheChase: The film turns into this when Thornhill starts running for his life.
* ChekhovsGun: A literal one. The gun [[spoiler:Eve]] uses on Thornhill in the diner scene [[spoiler:is first revealed as loaded with blanks after Thornhill is revealed to still be alive. It's later revealed by Leonard to Vandamm to be loaded with blanks. Later on the housemaid uses it on Thornhill, and the blasts from inside the house give Eve the chance to grab the MacGuffin statue and escape with Thornhill]]. Could also count as a Chekhov's Boomerang.
** Also, the ROT matchbox. [[spoiler:Thornhill shows it to Eve first of all on the train to Chicago, then he later uses it near the end of the film to scribble a message inside to warn Eve of the attempt about to be made on her life.]]
* ChekhovsGunman: In the scene in the CIA [[spoiler:after the scene in the United Nations where Thornhill is framed as the murderer of the real Lester Townsend]], the Professor mention "their own agent" [[spoiler: who later turns out to be Eve]]. Literally, considering the diner scene.
* UsefulNotes/{{Chicago}}: We do go through Chicago on the way west.
* ClearMyName: Roger sets out to do this when he's accused of murder. This is a Hitchcock film, after all.
* ClimbingClimax: The final fight on Mount Rushmore.
* ConspicuouslyLightPatch: The climax takes place on the front of Mt. Rushmore. If you look very carefully in the moments in which you can see the full monument, you can see the blue-tinted line.
* ContrivedCoincidence: Several, beginning with Roger summoning a hotel bellboy at the very moment said bellboy is paging "George Kaplan".
* CoolCar: That Mercedes convertible they try to kill Thornhill in.
* CoolHouse: Vandamm's Frank Lloyd Wright-style abode in South Dakota.
* CoolTrain: The ''20th Century Limited''.
* TheCorpseStopsHere: The style in which Lester Townsend is killed, turning Thornhill into a fugitive.
* CrashIntoHello: Roger and Eve meet this way on the train. [[spoiler:Turns out this was all part of the plan]].
* CreatorCameo: Creator/AlfredHitchcock is seen getting a bus door slammed in his face, right after his name appears on the screen in the opening credits.
* CreepyBlueEyes: Leonard.
* CurvesInAllTheRightPlaces:
-->'''Eve''': I'm a big girl.\\
'''Roger''': Yeah, and in all the right places, too.
* DaylightHorror: The crop-duster attack.
* DeadpanSnarker: Roger Thornhill.
--> "Not that I mind a slight case of abduction now and then, but I have tickets for the theater this evening, to a show I was looking forward to and I get, well, kind of ''unreasonable'' about things like that."\\
\\
"Now you listen to me, I'm an advertising man, not a red herring. I've got a job, a secretary, a mother, two ex-wives, and several bartenders that depend upon me, and I don't intend to disappoint them all by getting myself 'slightly' killed."
** And the AffablyEvil Vandamm more than keeps up with him, leading to some fabulous one-liners and plenty of SnarkToSnarkCombat.
--->'''Vandamm:''' Has anyone ever told you that you overplay your various roles rather severely, Mr. Kaplan? First, you're the outraged Madison Avenue man who claims he's been mistaken for someone else. Then you play the fugitive from justice, supposedly trying to clear his name of a crime he knows he didn't commit. And now, you play the peevish lover, stung by jealousy and betrayal. It seems to me you fellows could stand a little less training from the FBI and a little more from the Actors Studio.
--->'''Roger:''' Apparently, the only performance that will satisfy you is when I play dead.
--->'''Vandamm:''' Your very next role. You'll be quite convincing, I assure you.
** Roger's mother is one, too.
--->'''Roger:''' I'm beginning to think that no one in the hotel has actually ''seen'' Kaplan.
--->'''Mrs. Thornhill:''' Maybe he has his suits mended by invisible weavers.
* DepravedHomosexual: Leonard is [[AmbiguouslyGay implied]] to be one.
* DisneyVillainDeath: [[spoiler: Valerian and Leonard (although Leonard was already dead from the bullet). Also, when Leonard tells Vandamm that Eve is revealed to be a ReverseMole, Vandamm tells him they will kill her by pushing her out of the plane when it's flying over water. Thankfully, Eve never makes it to the plane.]]
* DoubleMeaningTitle: As well as the ''Hamlet'' reference, it's also about how the protagonist has to go north on Northwest Airlines.
* DoubleReverseQuadrupleAgent: [[spoiler:Eve. When Roger first meets her, she seems to be merely a smart and coy civilian woman who is not involved in Roger's whole mess and simply helps him out because she's attracted to him. Then we find out that she's actually working for Vandamm and is even his mistress. And ''then'' we find out that she's really working for the government and is actually TheMole in Vandamm's entourage]].
* TheDragon: Leonard.
* DrivingADesk: Used seamlessly in the crop-duster scene.
* DrunkDriver: The bad guys force-feed Roger a quart of whiskey and put him behind the wheel of a car, sending him on his way. He somehow manages to avoid killing himself or anyone else, but gets thrown in jail. His mother and lawyer bail him out, taking these events to be his usual carousing hijinks over his frustrated explanation.
* ElevatorEscape: Roger needs to flee a hotel before the villain's goons come for him, and he reaches the elevator going down - just as they get out of the next elevator, and promptly follow him in. Roger has his mother in tow, who refuses to believe he's in any danger.
* EmbarrassingMiddleName: Roger Thornhill's middle initial is O, making his initials R.O.T. Doesn't stop him from having his matchbooks monogrammed, though. This is actually a subversion, as Roger explains that the O doesn't stand for anything, he just added it so it looked like he had a middle name.
* EvenEvilHasLovedOnes: Vandamm really was genuinely fond of Eve. [[spoiler:He does not take her betrayal well. Not at all.]]
* EveryoneCallsHimBarkeep: The Professor.
-->'''Thornhill:''' I don't believe I caught your name.
-->'''Professor:''' I don't believe I pitched it.
* EvilBrit: Vandamm.
* EvilMinions: Valerian, Licht, "Mrs. Townshend", etc.
* ExpositionCut: When Roger is brought up to speed, the exposition is drowned out by the noise of the plane engines, since we already know this stuff.
* FailingATaxi: The film begins in New York City - a man hails a cab, and Roger cuts in with his secretary, claiming she's pregnant, and takes it. She chides Roger, who assures her his lie let the guy think he was doing them a favor.
* FemmeFatale: Eve Kendall.
** [[spoiler:FemmeFataleSpy: Doubly so once it's revealed she's the ReverseMole working for the United States government]].
* FiveBadBand:
** BigBad: Phillip Vandamm.
** TheDragon / TheEvilGenius: Leonard.
** [[TheBrute The Brutes]]: Valerian and Licht.
** TheDarkChick: The fake Mrs. Townsend.
* {{Foreshadowing}}: A few times.
** The Professor, when we first see him, mentions their own agent [[spoiler:who turns out to be Eve]], and how said agent will be endangered if word that Kaplan doesn't exist reaches Vandamm, their life will be compromised. [[spoiler:This does indeed go on to happen later, and in order to protect Eve, Thornhill has to pretend to be Kaplan]].
** Thornhill on the phone to his mother in Grand Central Station foreshadows the crop-dusting sequence once he arrives in Chicago as well as his first meeting with Eve: "The train, it's safer... Well, because there's no place to hide on a plane if anyone should recognize me... Oh, you want me to jump off a moving plane?"
** At the art auction [[spoiler:Thornhill and Vandamm's dialogue foreshadows the events of the diner scene]]:
---> '''Roger:''' Apparently, the only performance that will satisfy you is when I play dead.
--->'''Vandamm:''' Your very next role. You'll be quite convincing, I assure you.
* FunnyBackgroundEvent: During the scene where Eve pretends to shoot Thornhill, you can clearly see a kid in the background plug his ears in anticipation. Eva Marie Saint notes in the making of special that there were other good takes, and she has no idea why that one was used.
* GambitPileup: Vandamm, the Professor, Thornhill and Eve have their own elaborate plans, which clash constantly.
* GambitRoulette: Roger is abducted and nearly killed by someone pretending to be Townsend, whom Roger later learns is a UN diplomat. After narrowly surviving the attempt on his life, Roger visits the UN General Assembly building to confront Townsend. Townsend turns out to be someone he has never seen before, and shortly after Roger arrives, is killed by one of the men who tried to kill Roger. Roger was manipulated into meeting Townsend so that Townsend's enemies could kill him in a way that would look like Roger was responsible. But how did they know Roger would seek Townsend out? And if they needed Roger as a patsy, why try to kill him? And how did they know the attempt to kill Roger would fail?
* {{Gayngster}}: Leonard, though this being the 1950s, it's only implied.
* GivingThemTheStrip: Eve discards her scarf, jacket, and shoes in succession during the Mount Rushmore chase.
* GoSeduceMyArchnemesis: Eve was supposed to seduce Thornhill for the explicit purpose of leading him to his death in a cornfield. It doesn't work.
* GoingByTheMatchbook: Roger writes a warning to Eve on his personal matchbook with his initials (R.O.T.) on them and secretly throws it next to her at Vandamm's house. When they first met on the train earlier Eve noticed his matchbook and asked what the "O" stood for. Roger's reply: "Nothing". This was a sly dig at producer David O. Selznick, with whom Hitchcock had regular battles for creative control; his middle initial also didn't stand for anything.
* GreyAndGrayMorality: Vandamm and Leonard are up to no good but the US government is indifferent to the plight of Thornhill, even though his life gets screwed over because of their misinformation campaign. Later, the government even [[spoiler:tells Eve Kendall to sacrifice Thornhill for the greater good, leading Eve to send Roger out to get killed in the cornfield. The government finally decides to step in and save Thornhill but tell him that Eve will be married to Vandamm and serve as TheMole which makes Roger angry telling the government (as an AudienceSurrogate) that if that was their way of fighting the UsefulNotes/ColdWar, maybe they should ''lose'' it]].
* HammerAndSickleRemovedForYourProtection: The movie never mentions exactly who Vandamm and his associates are passing government secrets on to, although it's vaguely implied to be [[SovietRussiaUkraineAndSoOn some foreign country]]. The line "War is hell, Mr. Thornhill. Even when it's a cold one." is as close as the movie comes to spelling it out.
* HandStomp / HangingByTheFingers: The climax sees Roger holding onto the edge of a cliff while attempting to help up Eve. Then Leonard appears. When Roger asks him for help, Leonard decides to step on his fingers and get them to fall. Although he is later shot by a sniper in the distance.
* HaveAGayOldTime: During the scene where Vandamm meets with Thornhill at the Mount Rushmore cafeteria:
-->'''Vandamm''': And now, what little drama are we here for today? I really don't for a moment believe that you've invited me to these gay surroundings to come to a business arrangement.
* HeKnowsTooMuch: Vandamm believes Thornhill is guilty of this trope, believing him to be George Kaplan, despite Thornhill's arguments to the contrary.
* HeroStoleMyBike: After the crop-duster crashes, Thornhill steals the truck of a passer-by to get back to Chicago.
* HighHeelFaceTurn: Eve, [[spoiler:although it turns out that she was a ReverseMole all along]].
* IdiotBall:
** Not once, but ''twice'' the villains choose an overly elaborate method to try and kill Thornhill, from which he is easily able to escape: first by getting him drunk and putting him behind the wheel of a car so that he'll drive into the ocean and it'll look like an accident, and the second being the entire scene with the crop duster. Hitchcock did acknowledge that the crop-duster scene is needlessly complex, but pointed out that no one thinks that [[FridgeLogic while they're actually in the cinema]].
** When Valerian kills Townsend with the knife, Thornhill grabs it, making it appear as if he is the murderer. Now he has the police to worry about.
** Also defied, as when he calls his mother after that, he says taking the train is safer than taking a plane as if someone was looking for him, it would be easier to hide on a train.
* IfWeSurviveThis: Roger promises Eve that if they survive the final confrontation on Mount Rushmore, they'd go back to New York on the train.
* IfYoureSoEvilEatThisKitten: [[spoiler:Eve Kendall, the spy, proves her loyalty to Vandamm by shooting Roger Thornhill, or so it seems until Leonard figures out the truth. This is averted earlier, where Eve earlier did betray Thornhill to Vandamm after meeting him on the train and the US government were indifferent to Thornhill getting killed. Eve, still under her cover as spy, hugs Thornhill upon finding out that he was alive]].
* ImADoctorNotAPlaceholder: "I'm an advertising man, not a red herring."
* ImpairmentShot: Roger is force-fed a bottle of whiskey and put behind the wheel of a car - as he makes a getaway we see the road from his seeing-double perspective, curving and going straight at the same time.
* ImpliedDeathThreat: This exchange:
-->'''Vandamm''': It seems to me you fellows could stand a little less training from the FBI and a little more from the Actors Studio.
-->'''Roger''': Apparently, the only performance that will satisfy you is when I play dead.
-->'''Vandamm''': Your very next role. You'll be quite convincing, I assure you.
* INeedToGoIronMyDog: [[spoiler:When Thornhill warns Eve that Vandamm and Leonard know of her duplicity, she tells them she left her earrings in her room and goes up there, where Thornhill tells her the statue Vandamm bought at the art auction has microfilm inside it, something she didn't previously know.]]
* IndyPloy: Thornhill quickly becomes adept at making escape plans on the fly.
* InfoDump: The government agency takes a few minutes to explain what we already know.
* InsultBackfire: During the action scene, Thornhill points out that a painting being auctioned looks like a fake. A woman sitting near him says, "You're no fake. You're a genuine idiot." Thornhill simply says, "Thank you."
* InternalReveal: The audience learns the truth about Kaplan at the end of the first act. See PlotBasedVoiceCancellation for when Thornhill finds out.
* InventedIndividual: George Kaplan is a phony agent who attracts attention away from real operatives.
* InvulnerableKnuckles: When Vandamm wallops Leonard, he has to reset his knuckles before continuing.
* ItWasHereISwear: When Thornhill takes the county detectives back to the house where Vandamm and his two goons had detained him. For instance, there are a lot of books where he remembered the henchmen getting a bottle of bourbon.
* ItWorksBetterWithBullets: Happens; Vandamm's housekeeper holds Roger at bay with a gun she's picked up. Unfortunately for her, it's the same gun Eve used to fake shooting him earlier; it's only loaded with blanks, and he knows it.
* KarmicDeath: [[spoiler:Leonard gets shot by a sniper and falls over the edge of Mount Rushmore when he tries to cause Thornhill and Eve to fall off by stepping on Thornhill's fingers.]]
* KnifeNut: Valerian.
* LadyInRed: Eve wears a red dress in the climax of the movie, and when Thornhill confronts her after the crop-duster sequence.
* LandmarkingTheHiddenBase: The villains have a house on Mount Rushmore's peak.
* LiteraryAllusionTitle: From ''{{Hamlet}}'':
-->I am but mad north-northwest; when the wind is southerly,\\
I know a hawk from a handsaw.
* LostInACrowd: As his train arrives in Chicago, Roger evades detection by the waiting police by dressing as a redcap (railroad baggage handler) - by the time the police find the real redcap onboard without his uniform (which Roger paid him for), Roger has disappeared into a sea of redcaps.
* LostInTheMaize: The crop-duster attack takes place in and around a cornfield.
* MacGuffin: Both the microfilm and George Kaplan, since the first two acts of the movie are about Thornhill and Vandamm both looking for the nonexistent spy.
* MakeItLookLikeAnAccident: The enemy spies' first attempt to kill Thornhill plays this straight, where they force him to drink a whole bottle of bourbon, stick him in a car and drive it into the ocean so it appears he killed himself drink-driving.
* MatchCut: One comes at the very end, as Roger goes from [[TakeMyHand offering his hand]] to Eve on the cliff to pulling her onto the overhead bunk in a train cabin.
* MeaningfulBackgroundEvent: If you listen very closely to the background in the opening scene where Thornhill is sitting in the hotel bar with his associates, you can hear a bellboy announcing there's a page for "George Kaplan." Thornhill puts his hand up for an unrelated reason (he wants to send a telegram), and the spies ''assume he's Kaplan'', answering the page. It's very easy to miss unless you're looking for it.
* MeaningfulName: Two.
** Emile Klinger, the officer who arrests Thornhill for drink-driving after the first attempt on his life. The man's surname refers to Thornhill's attempts to cling to reality as at first he doesn't know what is going on. Also doubles as Foreshadowing [[spoiler:to the Mount Rushmore scenes at the end of the film]].
** Townsend. The murder of the real Lester Townsend (Town-Send) sends Thornhill from New York to Chicago to South Dakota.
* MischiefForPunishment: Thornhill intentionally gets himself arrested for disorderly conduct to escape the men at the auction who want to kill him.
* MissedTheBus: In his cameo, Hitchcock narrowly misses his bus.
* MistakenForBadass / MistakenForMurderer: Valerian tries to kill Thornhill with a knife in the United Nations, but it hits the real Townsend and Thornhill makes the mistake of picking up the knife in front of the crowd, making it appear he is the perpetrator.
* MistakenForSpies: The entire basis of the film.
* MommasBoy: Thornhill, at least to the extent that it's Mother who he calls to bail him out of jail and assist him in casing "Kaplan"'s room at the Plaza.
* MonumentalBattle: The end of the film takes place on Mount Rushmore.
* TheMountainsOfIllinois: The film features a treacherous drunken car chase along the Cliffs of Glen Cove, played in this picture by the cliffs of the California coastline. The north shore of Long Island is rocky, but not THAT rocky. Also, the cropduster attack scene was filmed near Bakersfield, California, not in the middle of an Indiana cornfield, although the appropriate highway signs were transplanted. Indiana doesn't look as dry as it does in the movie, even during droughts.
* MrExposition: The Professor.
* MuggedForDisguise: Thornhill is able to slip out of the train station in Chicago, despite being the object of a huge manhunt, by dressing in a Red Cap’s uniform. Later, the REAL Red Cap is seen in his longjohns, being questioned by the police about the man who stole his uniform. (But then it turns out that he wasn’t really “Mugged For Disguise” so much as “Bribed For Disguise,” because we see him counting a wad of cash, presumably paid to him by Thornhill.)
* MumLooksLikeASister: Creator/CaryGrant was 55 years-old at the time. Jessie Royce Landis, who played his mother, was 63 years-old, meaning she would have to have given birth when she was 8 years old.
* MysteriousMiddleInitial: Roger O Thornhill. Turns out the O doesn't stand for anything.
* ObfuscatingStupidity: Thornhill does this during the auction scene to make himself look like an idiot, causing the police to be called and escort him past Vandamm's goons covering the exits.
* OhCrap:
** Thornhill after the murder of Lester Townsend and realizing everyone thinks he's done it because he has the murder weapon in his hand.
** Thornhill when he sees the crop-dusting plane bearing down on him. And then again when it looks like the truck he is flagging down is about to run him down.
* OrbitalKiss: Played with. The train car in which Roger and Eve perform their first kiss proved too small to allow a cameraman to rotate around them, so the actors turned around while kissing.
* OverlyNarrowSuperlative: "You're the smartest woman I've ever spent the night with on a train."
* PaperThinDisguise: To try and hide his identity in Grand Central Terminal, Thornhill dons a pair of sunglasses. The man at the counter is GenreSavvy enough to guess who he is, but Thornhill manages to escape.
* PlayingGertrude: Jessie Royce Landis, who plays Thornhill's mother, was only seven years older than Cary Grant in real life.
* PlotBasedVoiceCancellation: The Professor explains the whole "George Kaplan" scenario to Thornhill at the airport, and his voice is drowned out by the roar of plane engines. This is actually a rather clever inversion of the trope, in that we the viewers already know about the stuff he's talking about, so making the conversation inaudible is sparing us from the redundancy.
* POVCam: When a park ranger slugs Thornhill in the face on the Professor's orders, to prevent his detaining Eve.
** Also later on when Vandamm punches Leonard after the latter proves to the former that Eve [[spoiler: [[DeathFakedForYou didn't really shoot Thornhill]]]].
* ThePrecariousLedge: Thornhill escapes the Professor's custody in the Rapid City hospital by navigating one of these. Then later, he and Eve are forced into scaling the top of Mount Rushmore to escape Vandamm and co.
* ProductPlacement: Northwest Airlines has a sign at Midway Airport.
** Which makes for a very subtle, nonverbal TitleDrop: Thornhill and the Professor fly ''north by Northwest'' from Chicago to Rapid City.
** Also a quick but clear shot of a Bergdorf Goodman label inside Eve Kendall's purse.
* RedHerring: Thornhill becomes one in the film against his will and uses the phrase to the Professor: "I'm an advertising man, not a red herring!"
* RedShirt: The real Lester Townsend, who only serves to show that the man Thornhill thought was Townsend is not who he thought he was, and to be killed so that Thornhill now has to clear his name of a crime he didn't commit.
* [[RemonstratingWithAGun Remonstrating With a Knife]]: Lester Townsend is surreptitiously stabbed in the back by Valerian as he talks with Thornhill at the UN. As he falls forward, Thornhill catches him, and seeing the knife pulls it out of Townsend's back. Only then does the large crowd around them notice what's happened, and the trope is duly invoked.
* RevealingHug: Roger is on the lam, meets Eve on a train, they get on very well... as he holds her we see her cool, calculating face, having slipped a note to his pursuers in the next compartment.
* ReverseMole: [[spoiler: Eve is made out to be Vandamm's mistress, but she's working for the government.]]
* RuleOfThree: Happens a few times.
** First, three attempts are made by the enemy spies on Thornhill's life: getting him drunk by forcing a whole bottle of bourbon down his throat, putting him behind the wheel of a car so that he'll drive into the ocean and it'll look like an accident, a knife is thrown at him but it misses and kills the real Lester Townsend instead, and finally the crop-duster sequence.
** The film takes place in three main locations: New York, Chicago and South Dakota.
** Roger uses a bathroom as a hiding place three times, two of them during the train sequence.
** [[spoiler:At the end of the film, Eve has become Thornhill's third wife.]]
* SafetyInMuggles: Thornhill in Grand Central Terminal after being wrongly suspected of the murder of the real Lester Townsend, and again during the auction scene.
* ScrewThisImOuttaHere:
** Subverted twice when Thornhill makes an unsuccessful escape attempt. The first time, after Valerian and Licht escort him to the car, he goes for the door, only to find it locked. He tries again at Townsend's estate, only to find Valerian blocking the doorway.
** Double-subverted in the auction scene, where he tries to leave and finds the exits covered, so he makes an idiot of himself to get the police called and escort him out.
** [[spoiler:Eve at the end does this when the gunshot rings out and she uses the distraction to snatch the statue from Vandamm and run.]]
* SerialSpouse: Thornhill mentions having two ex-wives a few times. [[spoiler:At the end, Eve is his third.]]
* SexFaceTurn: Eve, [[spoiler:although technically since she was a mole all along she never really loved her crime boss partner in the first place]].
* SexyDiscretionShot: The film ends with a shot of a train entering a tunnel as Roger and Eve are about to make love. Knowing Hitchcock's sense of humour, this was deliberate.
* SingleMaltVision: Played disconcertingly straight - after Roger is force-fed a quart of whiskey and put behind the wheel of a car, he's trying to escape his pursuers, and seeing the road before him go two different directions.
* SharpDressedMan: Thornhill dresses in the same grey suit for much of the film, only changing his attire near the end after being provided with fresh clothes. Vandamm, Leonard, Valerian and Licht also all dress in suits.
* ShirtlessScene: At one point we see Roger in a hospital room wearing only a white towel.
* ShoutOut:
** Seeing Vandamm and Leonard together with Eve at the Chicago art auction leads Thornhill to comment, "The three of you together. Now that's a picture only Creator/CharlesAddams could draw."
** In the same scene Vandamm tells Roger that with all the roles he's been playing, he could use "a little less training from the FBI and a little more from the Actors Studio." Eva Marie Saint and Martin Landau both studied there.
** [[ShoutOut/ToShakespeare Shout Out: To Shakespeare]]: Some theorize that the title refers to Theatre/{{Hamlet}}'s line that he's only pretending to be insane: "I am but mad north-northwest."
** When Roger is pretending to shower in the Chicago hotel room, he starts whistling "Film/SinginInTheRain".
* ShownTheirWork: When Thornhill and his secretary ride in a taxi from his Madison Avenue workplace to the Plaza Hotel, the [[DrivingADesk rear-projected]] view shown through the back window is of [[http://www.scoutingny.com/?p=5917 the actual route between the two locations]].
** Every location is [[TitleDrop north by northwest]]. For example, said Manhattan taxi ride, New York to Chicago, and so on.
* SissyVillain: Leonard refers to his suspicion of who the double-agent is as his "woman's intuition" and Vandamm comments that he thinks Leonard is jealous of his relationship with Eve.
* SorryOciffer: Thornhill is force-fed a quart of bourbon and put behind the wheel of a car on a cliffside road to kill himself. He manages to escape his foes, but gets caught by the police. At the station he absolutely admits that he's drunk, but can't get them to believe the circumstances.
* SpannerInTheWorks: Thornhill screws up both plans (see below) before being incorporated into them.
* SpiritualSuccessor: To previous Hitchcock films ''Film/{{The 39 Steps|1935}}'' and ''Film/{{Saboteur}}''.
* StagedShooting: [[spoiler: Eve shoots Roger in the Mt. Rushmore restaurant with blank cartridges.]]
* StandardHollywoodStrafingProcedure: The crop duster attacking Thornhill, though in this case, it's not an attack plane but a regular plane with a passenger wielding a gun
* TakeMyHand: The end of the film where Thornhill and Eve are hanging off of Mount Rushmore.
* ThereIsOnlyOneBed: Roger hides out in Eve's room on a train ride to Chicago. As they make out passionately he observes there's only one bed, asking if she knows what that means. She knows - he's sleeping on the floor.
* TheyDo: [[spoiler:Roger and Eve are husband and wife in the final scene.]]
* TraitorShot: The film contains one of the more complicated uses of this trope. It's true that Eve is working for the villain, [[spoiler:but she turns out to be a double agent who is actually working for the US government, and she tries to balance betraying Roger with keeping him safe]].
* UncomfortableElevatorMoment: Played for black comedy, as Vandamm's henchmen follow Roger and his mother into a crowded elevator at the Plaza Hotel.
-->'''Mrs. Thornhill:''' You gentlemen aren't ''really'' trying to kill my son, are you?
** Cue the bad guys deflecting the question by breaking into laughter, which then [[ContagiousLaughter spreads to the rest of the elevator passengers, including Mrs. Thornhill]].
* {{Unishment}}: Roger causes an uproar in the midst of an auction by placing outlandish bids and getting confrontational with anyone who outbids him. Eventually, security is called to escort him out of the building — which is exactly what he wanted, since there were two men in the room who were planning to kill him.
* UnwittingPawn: Thornhill, up to a certain moment, is this to both the Professor's and Vandamm's {{plan}}s.
* VehicularAssault: Roger gets strafed by a cropduster. The attack ends when Thornhill gets the plane to crash into a gasoline tanker.
* VillainousCrush: Leonard apparently for Vandamm.
* VisualInnuendo: This film concludes with the "train going into a tunnel" version. [[http://www.youtube.com/watch?v=bSAisV76fRM Here!]]
* WhammyBid: Thornhill places comically-low bids at the auction and gets confrontational about it, in order to get himself arrested [[{{Unishment}} and thus get a police escort away from his enemies]].
* WhatHappenedToTheMouse: Licht, Vandamm's henchman wearing a hat, disappears without explanation midway through the film. In the script, he was one of the two men in the cropduster but there's nothing in the film to suggest this.
* WickedCultured: Vandamm
* WritingIndentationClue: Thornhill is able to figure out where Eve is going by finding the impression of an address she wrote.
* WronglyAccused: Thornhill, like many of Hitchcock's protagonists, although he is probably the most famous example.
