* CompletelyDifferentTitle - In Sweden, the film was infamously misstranslated as "Spindlarna" ("The Spiders").
* ExecutiveMeddling - Was going to be in color and 3D before the studio got cold feet. This could be argued to have been a good thing, as the planned color of the ants (green) could have been NightmareRetardant.
* FollowTheLeader - This film owes a bit to ''TheBeastFromTwentyThousandFathoms'' and ''Film/{{Gojira}}'', and was, itself, the inspiration for countless subsequent movies about big bugs, none of which were anywhere near as good as the three aforementioned films, and most of which wound up on ''Series/MysteryScienceTheater3000''.
* HeyItsThatGuy - one reason this is one of the best giant monster movies from the 1950s.
** That's James Whitmore as state policeman Peterson.
** There's [[MiracleOnThirtyFourthStreet Santa Claus]] as the not-so-mad scientist with the answers.
** And [[Series/{{Gunsmoke}} Marshall Matt Dillon]] leading the FBI against the ants.
** With [[Series/StarTrekTheOriginalSeries Spock]] making a cameo appearance as a USAF sergeant who doesn't believe reports of ant-shaped "flying saucers".
** And perhaps most famously, DavyCrockett himself is locked in the nut house following a run in with the ants.
* ReferencedBy:
** ''VideoGame/{{Fallout 3}}'', which has a quest called 'Those!' featuring giant fire-breathing ants.
** ''VideoGame/ItCameFromTheDesert'' is an open homage to this film.
** It also appears in ''VideoGame/ZombiesAteMyNeighbors'' as a DemonicSpider and the ''VideoGame/CommandAndConquerRedAlert'' secret campaign "It Came From Red Alert!", which also features missions with one-word, exclamation-pointed names like this film.
** The climax of the movie, including the rescue of the two children, is referenced in a Mark Hunt in ''VideoGame/FinalFantasyXII''.
* ScienceMarchesOn: Ants, at least ones in America, don't make noise; in the 1950s, this was a point of debate among entomologists, as ultrasonic microphones of the needed sensitivity didn't exist. Forgiveable today by the RuleOfScary as [[TropesAreNotBad the sound]] ''[[TropesAreNotBad is]]'' [[TropesAreNotBad very chilling.]]
