* AlternateCharacterInterpretation: Is Godzilla really such a bad guy in the film? When Godzilla awakens, he goes THROUGH Nagoya, but in no way destroys it. All the destruction Godzilla inflicts is caused by his clumsiness (his tail hits a gas tank startling him into firing his ray, his tail gets caught in Nagoya Castle and manages to knock it over dislodging it, he trips and falls into Nagoya Castle then smashes it in a fit of rage). If the removed U.S. version-only scene is to be taken into account, Godzilla may have been making a bee-line for the Pacific at which point, he is turned away by the blasts of the Frontier Missiles. Then, Godzilla spends the rest of the film loitering about on the Kanto Plain where he is continually attacked by the self defense forces for no real reason whatsoever.
* AwesomeMusic: Despite the theme being used in ''Film/KingKongVsGodzilla'' was removed in the English, the English version kept the music of that theme intact for this film. This theme would end up used two more times, in ''Film/GodzillaVsGigan'' (as stock music) and ''Film/GodzillaVsMechagodzillaII''.
* CounterpartComparison: Godzilla, ugly, durable and vicious vs. Mothra, beautiful, fragile and gentle.
* EnsembleDarkhorse: The living turtle skeleton on infant island. [[http://blogs.yahoo.co.jp/hukuromusi1017/63638017.html It even got a figure.]]
* HilariousInHindsight: The original US dub title naming Mothra "[[Film/TheThingFromAnotherWorld The]] [[Film/TheThing1982 Thing]]", which has inspired more than a few crossovers with Godzilla and the [[EldritchAbomination definetely much more terrifying thing.]]
* MisaimedMarketing: The US dub renamed the film as "Godzilla Vs. The Thing" and the promotional art tried to portray the monster Godzilla would duel as a tentacled horror so terrifying, that the poster art had to be censored and the only way to see how horrifying it was was to see the movie. Never mind that Mothra, who isn't remotely scary, is a good natured monster!
* SomeAnvilsNeedToBeDropped: The whole sequence on Infant Island, where the human protagonists ponder the horrors of nuclear testing and atomic war. Hamfisted? Undoubtedly. An important moral in the heart of the Cold War? Indubitably.
