The 2010 FilmOfTheBook of ''Literature/ShutterIsland''. It was adapted by Creator/MartinScorsese with Creator/LeonardoDiCaprio as Teddy Daniels, Creator/MarkRuffalo as Chuck Aule, and Creator/BenKingsley as Dr. Cawley.

!!The movie contains examples of

* AxCrazy: Andrew's wife Dolores crosses into this territory after [[spoiler: she drowns her children.]]
* BadDreams: Teddy has several dreams hinting at his DarkAndTroubledPast. [[spoiler:Mostly involving his daughter telling him he should have saved their family.]]
* BerserkButton: Reminding Teddy that he is [[spoiler:Andrew Laeddis]] causes him to become physically violent towards other patients.
* BigNo: [=DiCaprio=]'s character gets a pretty good one.
%%* BlastOut
* ByTheBookCop: Subverted. Teddy Daniels is on Shutter Island not only for a missing person's case. but to find Andrew Laeddis, the man responsible for Daniels's wife's death.
* CatapultNightmare: A few.
* TheConspiracy: Teddy believes there is one in Shutter Island's Ashecliffe Hospital starting with the disappearance of Rachel Solando and going further down to them involving Nazi experiments of the human mind. [[spoiler:Subverted, this is only a fake reality Andrew Laeddis has made up for himself and that his doctors are trying to prove isn't real.]]
* DespairEventHorizon: [[spoiler: see GoryDiscretionShot.]]
* {{Determinator}}: Teddy Daniels is very determined to find answers on Shutter Island. [[spoiler: This trope is actually Deconstructed because it's actually Andrew Laeddis refusing to accept reality.]]
* DrivenToMadness: [[spoiler:Subverted. They're actually trying to ''cure'' his madness. Played straight in that what happened to his wife and children really did make him crack before the start of the story]].
%%* TheEndingChangesEverything
* EpiphanyTherapy: Cruelly Subverted. [[spoiler:As of the end of the film, Dr. Cawley has gotten Teddy/Andrew to snap out of his madness twice. Neither time stuck. The movie ending somewhat suggests that Andrew is really cured, but is so guilt ridden at what he had done that he pretends to have regressed back to the Teddy Daniels fantasy so they will lobotomize him, and his last line in particular implies that he knows.]]
* EyeScream:
** 'If I sink my teeth into your eye right now do you think you can stop me before I blind you?'
** The description of a lobotomy, which [[spoiler: is very strongly implied to be the lead character's fate.]] A real lobotomy doesn't actually damage the eye''ball'', as this is gently pushed sideways to clear a path to the orbital fissures at the rear of the eye-socket. Still extremely creepy.
* FailureToSaveMurder: [[spoiler:Andrew feels he let his children die because he didn't get help for his wife earlier, and as a result has nightmares of his daughter telling him he should have saved all of them.]]
* {{Foreshadowing}}:
** "You can't just choose to be sane."
** Also [[spoiler: how Andrew (then believing himself to be Teddy) utilized matches to see in Ward C, after having told Sheehan (as Chuck) that Laeddis was a fire bug. This is arguable, as obviously he had to use something to see in the nearly-pitch-black ward, but it's heavily inferrable based on how much attention the movie pays to Andrew lighting each match.]]
** In addition, [[spoiler: Teddy told his partner that his wife was killed by smoke from a fire. A constant habit of his is smoking. Another arguable point, as it is the fifties, and smoking was encouraged at the time.]]
** [[spoiler: Smoke from a fire could have also been referring to the smoke from his gun, as shown when he hallucinates shooting it. Some films from that time period have similar lines]]
** [[spoiler:Chuck has a hard time taking off his gun when they first enter the facility. Any lawman would be able to take it off as quickly as Teddy.]]
** Early in the film, Teddy decides to quit the investigation early on due to Cawley refusing the meet his requests, saying he will file a report of the investigation, [[spoiler:but at this point he stammers, because he's not quite certain who it is he reports to. Chuck has to finish the sentence for him]]
%% FridgeLogic and FridgeBrilliance examples go on those pages, not here.
* GoryDiscretionShot: Most assuredly not always present, but still packs a wallop at [[spoiler:the ending, with the "peaceful" shot of the lighthouse. The [[HereWeGoAgain previous scene]] makes clear [[BodyHorror what will happen to Laeddis there]].]]
* HerrDoctor: Played with. Dr. Naehring is undeniably German (although [[FakeNationality played by a legendary Swede]]), but his accent is much lighter than required by the trope.
* HeroAntagonist: Dr. Cawley. [[spoiler:He seems really sad and regretful when he has to admit his own defeat.]]
* {{Homage}}: The film is absolutely crawling with them, in particular Creator/AlfredHitchcock/Vertigo.
** The crooked angles in the lighthouse are a homage to ''Film/TheCabinetOfDrCaligari'', a German film told from the perspective of an asylum patient.
** Key parts of the plot and overall theme may be an homage to ''Film/TheCabinetOfDrCaligari'' as well.
* IKnowYouAreInThereSomewhereFight: [[spoiler: Nearly the entire film is one, on the part of Kingsley's character. He fails. Or does he?]]
* IKnowYouKnowIKnow: A somewhat meta-example; any sufficiently GenreSavvy viewer should be able to spot the obvious twist a mile away, but the way the film plays out makes one constantly question whether or not that's just what the filmmakers want you to expect.
* InfantImmortality: Averted. Along with the dead children at Dachau, Rachel Solando killed her three children by drowning them [[spoiler:and by extension, so did Dolores]].
* IronicEcho:
** "Why are you all wet, baby?"
** "I gotta get off this rock, Chuck."
* {{Lobotomy}}: During the course of US Marshall Teddy Daniels's investigation into the titular mental institution, the procedure is mentioned as one method used to "cure" violent inmates that have proven otherwise unable to be helped. After a few {{PlotTwist}}s and meetings with [[spoiler: Andrew Laeddis]] and [[spoiler:Rachel]] it is held as a threat against Daniels in his attempts to escape the island. Finally, after TheReveal, [[spoiler:The whole plot is revealed as an elaborate set-up to give Daniels, who is actually Laeddis committed to the asylum after killing his wife because she murdered their children in her own insanity, one last chance to cure himself. He experiences MyGodWhatHaveIDone and chooses to maintain the fantasy, knowing that it will mean death or worse, and undergo the procedure.]]
* ManlyTears: Teddy sheds these a lot, to the point of being TheWoobie.
* MrExposition: Dr. Cawley's wordy explanation of [[TheReveal what was really going on]].
* MrImagination: Teddy Daniels thinks he's in an investigation solving the case of a lost patient while seeking revenge against Andrew Laeddis for killing his wife. He actually is [[spoiler:Andrew Laeddis and is a patient at Shutter Island.]]
* NietzscheWannabe: The Warden.
** Although [[spoiler: considering that by the point in the movie where we first meet the warden was when Andrew was coming off the Chlorazapine and [[UnreliableNarrator obviously hallucinating]], we don't really know if that conversation actually happened or was [[ThroughTheEyesOfMadness simply a part of Andrew's delusion]].]]
** Not to mention [[spoiler: he could just be venting his frustrations with the guy he's talking to, who is the most violent and dangerous patient he's ever had to deal with.]]
* NoHoldsBarredBeatdown: Teddy violently does this to a patient in Ward C. [[spoiler:He also gave one to George Noyce because he called him Laeddis, and Dr. Cawley tells Andrew he's the most violent patient they have.]]
* OneDialogueTwoConversations: [[spoiler:As we later learn, Laeddis' delusions led him to completely misunderstand what George Noyce was talking about.]]
--> [[spoiler:"It's about you and Laeddis. That's all it's ever been about", implying that "it" was about Daniels vs. Laeddis]]\\
As opposed to: [[spoiler:"It's about you. And, Laeddis, that's all it's ever been about", implying that Daniels ''is'' Laeddis and everything was focused around him.]]
* PostHistoricalTrauma: The film actually deconstructs FilmNoir of TheFifties by dealing with the subtext of post-war trauma and wider social tragedy that came out of WWII. [[spoiler: Andrew/Teddy was a soldier in the liberation of the Dachau Concentration Camp and participated in a real life massacre of surrendering Nazi soldiers, a crime that, TruthInTelevision, was suppressed by the Allied Authorities until being de-classified decades later.]]
* PapaWolf: [[spoiler: Laeddis kills his wife after she goes AxCrazy and murders their children.]]
* RoomFullOfCrazy: Downplayed in a scene where we swiftly see a prison inmate using his blood to write something on the cell wall.
* ShootTheShaggyDog: [[spoiler:It turns out Teddy Daniels and the investigation is a fake persona created by Andrew Laeddis to hide the truth that he murdered his mentally ill wife after she murdered their children. As a patient, Laeddis has been living a fake reality to run away from the truth. In the end, he continues to act delusional and decides that he would rather be lobotomized, in his words, "die a good man" rather than continue to "live as a monster".]]
* SignificantAnagram: [[spoiler: Four of them, hence the "Rule of Four." Edward Daniels/Andrew Laeddis, and Rachel Solando/Dolores Chanal.]]
%%* TentativeLight
* TerrifyingPetStoreRat: A whole swarm of rats on the cliffside, which seem curious but not at all hostile.
* ThereAreNoCoincidences: Chuck lampshades that Teddy being called for an investigation to the island where George Noyce (a past acquaintance) is being held sounds too much like a ContrivedCoincidence. [[spoiler:Chuck who is actually Dr. Sheehan is trying to expose Andrew's made up reality.]]
* ThereAreNoTherapists: [[spoiler: Completely, utterly inverted. The whole island is orchestrating a therapy session to play along with the main character's delusions to see if he can resolve his own internal conflicts without help. They are trying to simulate a ThereAreNoTherapists scenario.]]
* TomatoInTheMirror: Carried over from the novel. [[spoiler: Teddy spends the whole movie chasing after Andrew Laeddis, the man who killed his wife. Near the end it's revealed that he ''is'' Laeddis, and invented the Teddy Daniels persona so that he wouldn't have to deal with the guilt of shooting his wife after she drowned their children in a lake. He's been a patient at the hospital for the last two years.]]
* TrailersAlwaysSpoil: [[spoiler:Why do we keep spoiling Daniels's insanity, guys?]]
* TwistEnding: A truly nasty one, too.
* USMarshal: Two U.S. Marshals, Edward "Teddy" Daniels and his new partner, Chuck Aule, travel Shutter Island, as part of an investigation into the disappearance of patient Rachel Solando.
* VerbalBusinessCard: "My name is '''EDWARD DANIELS!!'''"(twice). Later: [[spoiler:"My name is Andrew Laeddis, and I murdered my wife in the spring of 'fifty-two."]]
* WeaponStomp: Done very nastily. [[spoiler:The Nazi reaching for the gun had blown his cheek off in a suicide attempt and was lying on the floor bleeding out. He reached for his dropped gun to try again, only to have the protagonist step on it and drag it away.)]]
* WhamLine:
** [[spoiler: "You don't have a partner, Daniels. You came alone."]]
** [[spoiler: "Your name is Andrew Laeddis. The sixty-seventh patient at Ashecliffe? He's you, Andrew."]]
** [[spoiler: "Your children, Andrew, your children!"]]
** [[spoiler: "Honey?... Where are the kids?" "They're at school." "...It's Saturday. School's not open on Saturday." '''"My school is."''']]
* WindmillCrusader: [[spoiler: The main character]].
* WorldOfCardboardSpeech:
--> '''Teddy''': Which would be worse? To live as a monster, or die as a good man?
* YouAreWhatYouHate: Teddy Daniels doesn't sympathize for the patients because in most cases they've committed murder. [[spoiler:In reality, he killed his wife and confesses he is a monster who would rather die a good man in the final scene.]]
