''The Incredible Shrinking Man'' is a movie based on the book by Creator/RichardMatheson titled ''The Shrinking Man''. In the movie, a man named Scott Carey is exposed to some type of dust cloud (generally assumed to be radioactive) and the result is that he begins to slowly shrink. It is considered one of the better shrinking movies because the script is considered intelligent and the science is a little more believable.

In 2015, the book had a comic adaptation from IDW Publishing (Creator), which was distributed in a 4 issue miniseries from July to October. It shares the title with the book and is closer in terms of story detail. Though the variant cover to Issue 3 uses the movie title.
!!The Movie provides examples of:

* AdaptationDistillation: In the novel, Scott had a daughter. A couple other admissions from the movie:
** At 42 inches, Scott has some trouble with his car and hitches a ride with a guy. Problem is that [[spoiler: the guy believes Scott is a preteen kid and tries to hit on him.]]
** Scott has shrunken to about three feet tall when he encounters a group of boys. When they realize he's that "Shrinking Man" [[spoiler: they want to take his pants off to see if EVERY part of him had shrunk.]]
* AlasPoorVillain: During his monologue at the end of the film, Scott says that he understands that the spider was also just trying to survive.
* BittersweetEnding[=/=]DownerEnding: Mileage will vary on which one this is. Scott's voice-over monologue at the end has him accepting the inevitable and reaffirming that no matter how small he is, he will still matter in this universe. That doesn't change the fact that he will eventually shrink to ''atomic size'' or worse, that his wife assumes that their cat had eaten him.
* CatsAreMean: You just knew that the cat was going to try to eat poor Scott when he got small enough.
* GiantSpider: Technically, the spider is normal sized, it's Scott that's small, but from his POV, it ''is'' giant.
* HollywoodScience: Due to the SquareCubeLaw but may have been mildly averted; see below. Of course, as he gets smaller and smaller there are other issues not related to the Square/Cube law that would become very problematic and eventually kill him, but like most films of this nature these issues are ignored. As he gets extremely small he'd freeze to death because his body would lose heat faster than it produces it (this is why birds have feathers and small animals have fur), his lungs would not work properly when he is insect-sized (insects don't have lungs and rely on air pressure to force oxygen into their bodies through special openings), food would become impossible to find or digest, and once he shrinks small enough the air molecules would be too big for him to breathe.
* HopeSpot: An antidote is found that stops his shrinking at three feet, and a friendship with a midget helps him realize that it's possible to live happily even at that size. [[spoiler:Then the antidote stops working.]]
* ILoveNuclearPower: As stated in the summary, the cloud is generally assumed to be radioactive.
* IncredibleShrinkingMan: The trope namer of course
* MagicPants: Completely averted. Scott's physical body gets smaller while his clothes don't. As a result, he is forced to wear children's clothes, doll clothes and the rags from his doll clothes.
* MouseWorld: From the scenes in the dollhouse to being chased by the cat, and finally being trapped in the cellar. In the cellar, this is the epitome of the Mouse World. Scott is forced to eat crumbs from a stale cake, live inside a match box and fight off a spider.
* NarratingThePresent One interesting this is that Scott's voice remains the same pitch despite his getting smaller as the film progresses, unless we're reading his mind...
* SquareCubeLaw: Quite possibly averted because Scott ''slowly'' shrinks, thus giving his body a chance to adapt.
