History Film / TheFlyII

* TheSleepless: Martin sleeps very little from birth onward. (In the previous film, in the early stages of his transformation Seth mentioned in passing that he was now this.)

* YoungerThanTheyLook: Martin Brundle ages to MrFanservice level in about six years.

* RapidAging: Martin ages at four times the normal human rate. He knows that this is abnormal; he just isn't aware of the actual cause. Bartok and his underlings tell him that he inherited a rapid aging disorder from his father, who ultimately succumbed to it. It is "controlled" by their (phony) injections, and they later convince Martin that finishing Seth's work could provide a cure. Only later does Martin learn the awful truth. This may or may not have been inspired by a plot point from ''Film/CurseOfTheFly'': The male lead of that movie actually suffered from this because their father's temporary transformation into a HalfHumanHybrid permanently affected his genetic makeup, and had to control it via injections. That male lead's name? ''Martin''.

* AndIMustScream: [[spoiler: Bartok's karmic end has him reduced to a hideously deformed mutant crawling around in a pit, pitifully squirming around, and barely able to even feed himself.]]

This may or may not have been inspired by a plot point from ''Film/CurseOfTheFly'': The male lead of that movie actually suffered from this as a side effect of their father's temporary transformation into a HalfHumanHybrid, and controlled it via injections.

* RecycledPremise: Of ''Film/ReturnOfTheFly'', the direct sequel to the 1958 film. Both have the SpinOffspring son of the predecessor's ill-fated scientist (who has spent much of his life unaware of exactly what happened to him) reviving his father's work and ending up undergoing much the same transformation he did -- much to the despair of his girlfriend, and no thanks to a seemingly supportive figure (an assistant in the older film) who wants to steal the teleportation technology. He goes after the villains, and [[spoiler: gets the happy ending his father could not]]. There are even similar small details: Both movies open with a scene establishing the demise of the female lead of the predecessor (in '59 with her funeral and in '89 with her DeathByChildbirth), while the third corner of the previous film's LoveTriangle is still alive, ''not'' enthused with the son picking up where the father left off but proving to be helpful nonetheless, and played by their original actor. The main differences lie in the nature of each protagonist's transformation — with Phillipe in ''Return of the Fly'' it's another TeleporterAccident; with Martin here it's a natural {{Metamorphosis}} due to being born as a mutant -- and the level of gore involved. Someone in 20th Century Fox's marketing department must have noticed this trope because the final trailer for this movie opens with a spiel involving the sound of a buzzing fly and the audience being asked if they can hear it — a '''verbatim''' lift from the ''Return of the Fly'' trailer!

* HonorBeforeReason: Martin discovers he can cure himself, but only if he uses a healthy human donor. He absolutely refuses to subject another person to what he's going through. [[spoiler:The whole truth about Bartok's actions, though, make it easy for him to reconsider this position]].

* RapidAging: Martin ages at four times the normal human rate. He knows that this is abnormal; he just isn't aware of the actual cause of it. Bartok and his underlings tell him that he inherited a rapid aging disorder from his father, who ultimately succumbed to it, and convince Martin that finishing Seth's work could provide a cure. Only later does Martin learns what really happened to his father and what this means for him.

* TheSleepless: Martin sleeps very little from birth onward. (In the previous film, in the early stages of his transformation Seth mentioned in passing that became this post-teleportation.)

* ThePasswordIsAlwaysSwordfish: Martin set up a password to protect the Telepods; an incorrect guess will even delete all the programming. Though apparently having a good idea of the correct answer, Bartok doesn't want to take any chances. At the conclusion of the rampage, Martinfly (by way of Bartok) types up the magic word: "DAD."

** Martinfly ''literally pets a dog'' in the middle of his murderous rampage through the facility.
** Another example, a not so literal one, is Martinfly sparing Beth Logan, his love interest, when he encounters her at one point. All of this suggests that Martin's mind is largely unchanged despite his body's metamorphosis.

* SurprisinglyHappyEnding: At least when one compares what becomes of Martin to what became of his father. ''The Motion Picture Guide'''s review snarkily pointed out that in this movie, the sins of the father being visited on the son leads to, [[spoiler: despite racking up a significant body count and leaving Anton Bartok a helpless mutant, Martin getting a happy ending as a fully-human being. Seth maimed two people and ''attempted'' a forced fusion with Veronica, and paid for that with his life when Laser-Guided Karma came calling and drove him to an assisted suicide]].

* CursedWithAwesome: Doubly so for Martin compared to his father, since his Martinfly form, while inhuman, turns out to be a coherent, seemingly healthy lifeform instead of a diseased, deformed mishmash of genetic goo (possibly due to being born with the fly genes instead of having them abruptly inserted into him as an adult). He's much more of a werefly / alien lifeform than the diseased corpse like wreck Seth ended up turning into in the first film.

* DeliberateInjuryGambit: [[spoiler:Granted, it's likely that it did legitimate damage, but Bartok is done in by Martinfly after the latter feigns fatal damage from Bartok's gunshot, letting Bartok get close enough so that he could grab and drag him into the telepod]].
* EarnYourHappyEnding: [[spoiler: In stark contrast to the first movie.]]

* EyeScream: At one point, during his transformation, [[spoiler: Martin ''pulls out his right eye to reveal an insect eye behind it.'']]

[[SequelGap In 2015,]] Creator/IDWPublishing released a five issue comicbook sequel to the film titled "The Fly: Outbreak", which follows Martin as he accidentally causes more genetic mishaps.

* BigNo: Bartok [[spoiler: when Martinfly drags him into the telepod with him.]]

* BodyHorror: The dog, though averted with Martin's transformation, as most of it takes place in a cocoon. [[spoiler: Bartok wasn't so lucky...]]

* ActionizedSequel: Features more gun related action scenes than the first and the fact Martinfly is more formidable than his sickly Brundlefly father from the first film.

* BodyHorror: The dog, though averted with Martin's transformation, as most of it took place in a cocoon. [[spoiler: Bartok wasn't so lucky...]]

* HappyEndingOverride: Not that the first film ended happily by any means, but it gets even worse for Veronica and Stathis in this one: [[spoiler: Veronica dies in childbirth and Stathis turns into a drunken JerkassWoobie due to the pain of losing her.]]

* LaserGuidedKarma: [[spoiler: Anton Bartok, the BigBad, who let Martin undergo his transformation and finish the teleporter for his own greedy ends, is ultimately fused with Martin's insect genes through the teleporter, turning him to a hideously deformed mutant.]] It becomes even more karmic [[spoiler: when the epilogue reveals that he's been placed in the same pit the mutated dog was earlier in the movie.]] It would have been even more so had the original scripted ending been shot: [[spoiler: Mutant!Bartok would have begged the now completely human Martin to kill him, only for Martin to shake his head, say "Sorry, dad" and feed him the slop he eats in the last scene.]]
* LikeParentLikeSpouse: Martin's girlfriend Beth bears a rather striking resemblance to his late mother Veronica. Which is especially odd considering that Martin has only met his mother for a few seconds before her DeathByChildbirth, though the film does show Martin displaying superhuman memory skills even as a toddler.

* MixAndMatchCritters: Averted, as Martinfly is far less mashed up than his father. Also [[JustifiedTrope justified,]] as Martinfly is at least 75% human.
* MohsScaleOfViolenceHardness: The first film was a 9 but this takes it up to 10 with an exponentially bigger body count, more maimings, and the fact that the audience is supposed to be on Martinfly's side and cheer on his RoaringRampageOfRevenge. In the original, Seth's growing inhumanity and the cruelty he inflicted on others was treated as a tragic, horrifying fall from grace.
* MookHorrorShow: The last leg of the film plays out like a typical horror film with a rampaging monster killing everyone, but in this cast the monster is the hero, giving his victims their just desserts.

* PainfulTransformation: Averted in the sequel, Martin's transformation is more natural as a deliberate counterpoint to Seth's. [[FridgeBrilliance His body literally undergoes the life cycle of an insect]] -- his [[YoungerThanTheyLook rapidly growing human form]] is functionally a larvae, his [[BodyHorror deforming body]] the instar, he develops a cocoon / pupa, and he emerges a powerful Insect Man hybrid. The Martinfly creature is [[SuperStrength very strong,]] [[LightningBruiser very fast,]] and [[PoisonIsCorrosive very deadly...]] The opposite of his father.

* RapidAging: Martin ages at four times the normal human rate. He knows that this is abnormal; he just isn't aware of the actual cause of it. Bartok and his underlings tell him that he inherited a rapid aging disorder from his father, who ultimately succumbed to it, and convince Martin that finishing Seth's work could provide a cure. Only later does Martin what really happened to his father and what this means for him.

* YoungerThanTheyLook: Martin Brundle in ''The Fly II,'' who ages to MrFanservice level in about six years.

* LighterAndSofter: In comparison to the first one at least. It still features a ton of grotesque imagery including seeing a dog get mutilated by a telepod experiment, and a guy peeling his face off after getting it covered in Martinfly's digestive juice.

* MookHorrorShow: The last leg of the plays out like a typical horror film with a rampaging monster killing everyone, but in this cast the monster is the hero, giving his victims their just desserts.

** The mutated protagonist of the sequel literally pets a dog in the middle of his murderous rampage through the facility.

* ActorAllusion: Eric Stoltz's character's name in ''The Fly II'' is Martin Brundle, and the creature he transforms into is nicknamed "Martinfly." Eric was originally cast as Marty [=Mc=]Fly in ''Film/BackToTheFuture,'' until he was replaced by Creator/MichaelJFox. Interestingly enough, Creator/JeffGoldblum, who played Martin's father Seth in the [[Film/TheFly1986 original 1986 film]], was considered for the role of Doc Brown in ''Film/BackToTheFuture'' also until he was replaced by his ''Film/TheAdventuresOfBuckarooBanzaiAcrossTheEighthDimension'' co-star Creator/ChristopherLloyd.

* MookHorrorShow: The last leg of the plays out like a typical horror film with a rampaging monster killing everyone, but the monster is the hero in this case who's giving his victims their just desserts.

* VillainousGloating: Scorby is a petty asshole security guard who stops to laugh at Martin and gloat about taping him and Beth in bed. Martin takes the opportunity to grab him, throw him through a window and escape.

* ActionizedSequel: Features more gun related action scenes than the first and the fact Martinfly is more formidable then his sickly Brundlefly father from the first film.

** A security guard who did't have the good sense to wait for backup or simply look up [[spoiler: leads to his face and one of his hands getting melted off]].
