!!!The 1958 movie contains examples of:
* BestKnownForTheFanservice: The film features an attractive, scantily-clad GiantWoman as its primary draw, which is certainly ''very'' appealing for a significant number of people for... certain reasons, which has definitely helped its CultClassic status.
* CultClassic: Even with atrocious "special" effects and a meandering story that fails to deliver on the premise until the last eight minutes, the movie, and its iconic poster, have nonetheless left a significant mark on pop culture (even being the TropeNamer for AttackOfThe50FootWhatever), more so than almost any other 50s sci-fi b-movie.
* NightmareRetardant: The giant alien just looks like a normal bald human, but everyone seems to see it as a unbelievably horrifying monster.
* {{Padding}}: Despite barely being an hour long, it takes ''forever'' for the premise to happen, with numerous dialogue scenes between inconsequential characters. Even the subplot involving the giant alien [[WhatHappenedToTheMouse ends up going nowhere]] and it still takes another twenty minutes for Nancy to "attack" after she's turned giant (and this is a huge flaw for a movie only ''an hour'' long).
* SoBadItsGood: A genuinely awful movie but it still has its fans for an unconventional "monster", interesting feminist subtext, hilariously terrible effects, and certain ''[[BestKnownForTheFanservice other]]'' reasons.
* SpecialEffectsFailure: Boy, howdy!
** Both the giant alien and Nancy appear translucent and glowing in several shots, presumably due to bad compositing.
** The use of the same walk cycle of Nancy composited into numerous different scenes, aside from the translucency issues noted, resulting in a particularly bad case of YourSizeMayVary since the scale doesn't line up at ''all''.
** Even for TheFifties, it's obvious Harry is just a doll when she picks him up.
** The giant hand used for the scenes where Nancy is supposed to be interacting with people has unnaturally floppy fingers at times and an ''unusually'' rough texture.
** The repeated reuse of the clip of Nancy walking results in a continuity error at the end when she's supposed to be holding Harry, since her hands are clearly empty.
** Given that the giant alien is dressed like a medieval soldier, it's clearly footage from a completely different movie.
* TheWoobie: The way Nancy is treated before she grows definitely sets her up for Woobie status.

!!!The 1993 movie contains examples of:
* SpecialEffectsFailure: In the far shots of Nancy carrying Harry he's clearly a doll.
* SugarWiki/VisualEffectsOfAwesome: The scene where Nancy bathes in a swimming pool is surprisingly impressive for a low-budget movie.
