->''"I want my molecules back!"''
-->-- '''Nick Halloway'''

Nick Halloway was a fairly ordinary stock analyst until he fell asleep in the building of Magnascopic Laboratories, a company for which he represented shareholders. That night, a FreakLabAccident occurs, apparently severely damaging the building; However, no debris is found. It turns out that the accident actually made certain parts of it completely invisible. One of those "parts" is Nick himself.

Desperately hunted by amoral {{CIA}} agent David Jenkins, Nick seeks to build a new life while avoiding becoming a scientific guinea pig stuck in a lab until he dies... or forcibly recruited into being a black ops specialist.

Originally a 1987 ScienceFiction novel by H. F. Saint, it was adapted into a 1992 film directed by Creator/JohnCarpenter, and starring Creator/ChevyChase and Creator/DarylHannah. The book analyzed what effects invisibility would have on an average person who kept his morality, and the movie tried to do the same. The book was a small success; the movie was considerably less well-received.
!!Tropes used in the movie:
* AdaptationNameChange: In the book, the company where the accident occurred is called [=MicroMagnetics=]; in the film it's called Magnascopic Laboratories.
* AttemptedRape: Richard, a friend of Nick's friend George, forces himself on Nick's RomanticInterest, Alice, at one point. Nick, present but unknown to either party at the time, throws Richard off.
* [[spoiler: BabiesEverAfter: Implied when Nick wonders what his and Alice's kids will look like. Played straight during the credits when we see Alice with a baby bump.]]
* BlessedWithSuck: Nick desperately wants to find a way to become visible again, although he gives up [[spoiler:when the scientist who might be able to figure out how to make that happen gets assassinated]].
-->I can barely ''sleep.'' I can see through my ''eyelids'', I can see through the top of my ''head.'' I get walleyed. I get bat-shit!
* CIAEvilFBIGood: The "CIA is Evil" part is present and accounted for full-force with David Jenkins. He desires Nick because he can be an invisible assassin (being a secret agent in and of itself would probably do, but Jenkins makes an emphasis on wanting to use Nick as an invisible ''assassin'') and becomes an ImplacableMan, using all kinds of lures to draw Nick out... even kill the guy who created the technology that turned Nick invisible, or take Alice hostage.
* CursedWithAwesome: Nick eventually figures out a way to make his lack of the usual invisiblity RequiredSecondaryPowers work for him. [[spoiler:When Jenkins corners him at a construction site, Jenkins sees where Nick brushed against some dust. When the view goes to where Nick really is, Nick is holding his jacket to the side, and throws it off the building to fake suicide.]]
* DespairEventHorizon: At the end, Nick reaches this, tired of being unable to live normally and of being hunted by the CIA, and he jumps to his death from a construction site. [[spoiler:Except he faked it, figuring that nobody would bother to look for him if they thought he was dead.]]
* DrivenToSuicide: At the climax at the construction site, when Jenkins has Nick cornered, Nick makes it clear that he'd rather jump off the building than be forced to work as a black ops assassin. [[spoiler: He's actually faking it, as noted above under CursedWithAwesome.]]
* IJustWantToBeNormal: Nick desperately searches for a way to become a normal, visible person again. [[spoiler: Even after he learns that it's impossible, he does his best to make it so that he can live as normal of a life as possible.]]
* InvisibleStomachVisibleFood: Applies to Nick. In the movie, there are several scenes in which Nick chews gum, drinks liquid, or otherwise ingests food and we see it hovering in air. In fact, the first time he notices is when looks in a mirror and sees food digesting in his stomach. [[VomitIndiscretionShot We hear the sound of vomiting]] and the food arches into the air and off-screen. He ends up switching to an all-clear foods diet so that he can't see the half-eaten food in his stomach, justifying it to the clerks he orders it from by saying his doctor has advised him to avoid food coloring. Later, as he attempts to hide from the BigBad, he refuses to eat so that he remains invisible.
* InvisibleStreaker: {{Averted}}-Nick has one outfit that was rendered invisible along with him, so he can wear that when he wants to remain invisible. This lead to a funny moment as it takes time for him to learn how to put his arms through sleeves of an invisible jacket.
* {{Invisibility}}: The plot revolves around what happens when a metaphorically invisible man accidentally becomes literally invisible.
** InvisibilityWithDrawbacks: The primary drawback to Nick Halloway's invisibility is that he cannot turn it off. This causes endless problems for him, not the least of which is that the government wants to force him to become an invisible assassin. Secondary problems include the fact that he only has one set of clothing that is also invisible, so he can be seen when he wears anything else. Also, anything he eats or drinks is perfectly visible as he chews, swallows and digests it, and that can be nauseating to watch.
* MiraculousMalfunction: It's implied that someone spilling a cup of coffee on a control panel resulted in uncontrolled but permanent invisibility, in a lab whose research had nothing to do with invisibility.
* NoPlansNoPrototypeNoBackup: Not only the problem lies in that what happened that created the invisibility effect is a complete unknown (and an industrial accident, to boot), but Jenkins makes things worse in that he wants Nick so badly that he decides killing the scientist that created the technology (and ''may'' be able to replicate things eventually) is a perfect way to draw Nick into the open.
* PersonalityPowers: A [[LonersAreFreaks socially invisible man]] actually becomes invisible; It's [[LampshadeHanging even noted]] when the CIA goes over his file:
-->Never been married, parents both deceased. The guy's got a few friends, but not real close to any of them. Not exactly a workaholic either. He kind of plays it fast and loose. It's always difficult with people like this. No strong emotional ties, no political beliefs, no particular interests. As a matter of fact, when you think about it, the man has the perfect profile. He was invisible ''before'' he was invisible.
* PowerIncontinence: Nick's issue with his invisibility is that he's stuck that way, and he wants at least the ability to turn it off.
* RequiredSecondaryPowers: Part of Nick's problem is that he has only some of these related to invisibility. His food isn't actually invisible until some time after he digests; he vomits the first time he sees himself in the mirror as it's digesting. The only thing that he can put on that's similarly invisible is the outfit he wore when rendered invisible; any dust that lands on him is visible. He can still see just fine, however.
* SeeTheInvisible: Usually the footprint method, though the "something all over" method is used intentionally a few times (for example, when Nick and Alice go out to eat).
* {{Technobabble}}: "...some molecular instability has made certain areas transparent."
* TheFilmOfTheBook: Albeit one that changes a lot of the source material - for starters, instead of New York the setting is the San Francisco Bay Area.
* VisibleInvisibility: Switches between types 1 and 5, though mirrors and camera footage always work as type 5. Additionally, in one scene where Nick is invisible on screen he gets rained on, and we see the shimmery outline of raindrops on him.

!!Tropes used only in the book:
* BadassNormal: Although being invisible means he really isn't normal, Nick is ''really'' badass. He plans for the future quickly and efficiently once he realizes his situation, makes good decisions about how to initially survive, plans for the long-term, and especially when he realizes that Jenkins simply won't give up, acknowledges that he is much too reactive, and plans and executes a way to turn the tables. Even when things go wrong with this plan, he improvises on the fly, and it works out. As Jenkins says in one of their phone conversations, Nick probably would have made a good field agent even if he weren't invisible.
* BigApplesauce: The primary setting, as the OneBookAuthor [[WriteWhoYouKnow worked on Wall Street]].
* CrazyPrepared: Nick does this when escaping the invisible building. Jenkins has the entire area sealed off, but it's too large to effectively box Nick in quite yet, so they go about the business of identifying the dimensions of the walls and floors with tape and string. While they work, Nick gets together everything he can that is invisible, and builds a "ladder" of invisible tables to get him and his possessions out without being immediately noticed. A lot of it comes in handy later, especially the cloth, which he is eventually able to make extra clothes out of.
* {{Determinator}}: Jenkins absolutely will not give up on finding Nick, and though Nick despairs a few times, he refuses to give up hope for a more normal life without Jenkins in it either.
* {{Handwave}}: The book gives an explanation for why some of the issues that would eventually get Nick in trouble don't, specifically dust and other small particles that should adhere to him and make him easier to "see". The book explains that the process that made him invisible also made it more difficult for other objects to form mechanical bonds with him, so not only does dust not stick to him, but water beads and runs off him almost immediately. However, the book forgets that this should make normal walking surfaces more slippery due to the reduced friction.
* NoPlansNoPrototypeNoBackup: The scientist who is responsible for the accident that makes Nick invisible started on research related to nuclear fusion, but went off on a tangent, and barely talked to anyone, even his assistants, about what he was doing. He dies in the accident that turns the entire building invisible, most of his notes are unreadable because they too are invisible, and Nick burns it down anyway to help his escape.
