[[NamesTheSame The name is also shared by]] a 2001 horror movie, made as a ''tribute'' to the original, though this version can be seen more as a DarkerAndEdgier {{Deconstruction}} of SpiderMan. This movie revolves around a comic book-loving security guard at a lab doing genetic modification research on spiders. When his partner is killed, he deliberately infuses himself with spider [=DNA=] in hopes of becoming like his favorite super-hero. Instead, he is warped into a [[BodyHorror grotesque hybrid of human and spider traits]] and is consumed by an insatiable appetite for human flesh, voraciously eating person after person until a police officer manages to shoot him before he can snack on the girl he had a crush on.

!!''Earth Vs The Spider'' contains the following tropes:

* ArtisticLicenseMusic: Real rock bands don't have conductors.
** Plus, whatever he's doing, it ain't conducting. "Having an epileptic fit while holding a stick" would probably be a better description.
* AttackOfTheFiftyFootWhatever: What do you think?
* BadassNormal: Mr. Kingman as he always maintains a cool head and has a logical scientific explanation for every circumstance. He proves to be the real hero of the film in not only being willing to fight the spider and being the one who devises the solution to permanently kill it.
* BigCreepyCrawlies: See title.
* CassandraTruth: Sheriff Cagle refuses to believe the kids about the existence of the giant spider until he can see it for himself. [[BeCarefulWhatYouWishFor He quickly changes his attitude about it when he does see it.]]
** Unusually for a movie of this type, Cagle ''does'' take the appropriate actions for a giant spider outbreak - even calling in a tanker truck of [=DDT=] and gas masks - on the say-so of the kids' science teacher Mr. Kingman. Neither he nor the half-dozen deputies and insecticide techs take it seriously, until one of them dies...
* ChekhovsGun: Mr. Kingman's lecture on electrons and poles, complete with demonstration. (A bit... heady for a ''high school'' science class, then or now, but it works.)
* DisconnectedByDeath: Hugo the high school janitor at the start of the spider's rampage in town.
* EnforcedPlug: We see ads for two other films by Bert. I Gordon: ''Film/AttackOfThePuppetPeople'' and ''Film/TheAmazingColossalMan''. The former is also worked into the dialogue.
* HollywoodDarkness: The cave. They don't even bother with flashlights or torches in the slightest, though this is HandWaved with a mention of luminescent algae.
** There's a reason for this: The movie was filmed in Carlsbad Caverns in UsefulNotes/NewMexico, but only if they didn't use any studio lights, as that would accelerate the growth of microscopic organisms that would deteriorate the cave's structure much faster.
* PassingNotesInClass: There's a pretty typical example between the two teenage leads during a tedious physics class. The teacher catches them, although he doesn't ask them to read it out loud.
* SomewhereAnEntomologistIsCrying: Spiders aren't insects, they're arachnids. You'd think a scientist would know that.
* SurvivorGuilt: Carol heavily blames herself for her dad's death.
* TooDumbToLive: Carol drops her bracelet in the giant cave after nearly being killed by the giant spider. What does she do? She goes back in to look for her bracelet, resulting in her and Mike nearly getting killed six ways to Sunday.[[note]]The bracelet was something her dad was planning to give her when he was killed, and she had every reason to believe the spider was both dead and ''not'' in the cave the second time they entered it.[[/note]]
* VersusTitle: It's barely ''one small town'', but presumably "A Single Small Town In The Middle Of Nowhere vs. The Spider" wouldn't have sold as well.
