'''''(The) Horrors of Spider Island''''' is a 1961 exploitation film.

A troupe of dancers is assembled in UsefulNotes/NewYorkCity for a special performance in Singapore. Unfortunately, their plane crashes and the survivors (the troupe plus their manager Gary and his assistant Georgia) become castaways on an island. A little exploration reveals that the island used to be the home of a scientist mining for uranium, before he was killed by spiders. One night Gary gets bitten by a spider and turns into a spider-monster, stalking his former friends and killing them.

The film was a German flick, but represented an interesting midpoint in cinema between the traditional horror film and the nudie cuties that would pop up in the early-to-mid 60's that would lead to the eventual creation of the MPAA ratings.

!!''Horrors of Spider Island'' contains the following tropes:

* AllWomenAreLustful: The ladies are stranded on an island, one of the only competent members of their group has gone missing, and the food's running out. When two average-looking men show up, you'd think the ladies would have bigger concerns than seducing them, but, well...
** The guys ''do'' bring food and supplies with them (they were resupplying the scientist who lived on the island), but [[AngstWhatAngst forgetting about their missing friends is harder to justify]].
** As Mike and the bots proved, when you're in a plane crash, you instantly become languid, helpless, and sex-starved, and you murmur a lot.
* AsYouKnow
* BatDeduction: When the other women find the body of Linda, the stripper, they find marks on her neck that indicate she's been strangled and immediately come to the conclusion that "the spider" had done it. Despite the fact that spiders ''poison'' their prey, not ''strangle'' them.
** The spider did try to strangle Gary, but they had no way of knowing that the spider is a strangling spider.
* DoesNotLikeShoes: The women start going barefoot all the time not long after crashing on the island.
* DoesThisRemindYouOfAnything: A man bitten by a radioactive spider turns into some sort of..."spider-man?"
** Actually predates SpiderMan by a few years. Maybe Creator/StanLee saw this movie and was inspired?
* DiggingYourselfDeeper: Joe and Anne. It starts with him saying he's glad her plane crashed (so he could meet her), and, well, if this movie were more competently written it ''would'' get worse, but the bit ends rather lamely.
* FailedASpotCheck: Plenty of easy ways to get killed by spiders by remaining unaware of surroundings.
* {{Fanservice}}: There's lots of scantily clad women in this movie. However, in the bathing scene, they wear light-colored body stockings. So they're nude, but they're not!
** The auditions themselves have the girls showing off their legs and getting nearly naked.
* ILoveNuclearPower: Just being ''vaguely near'' uranium deposits is enough to make spiders into giant mutants.
* TheImmodestOrgasm: The moans from the sun-stricken dancers sounds... erotic. {{Lampshaded}} and deconstructed by Mike and the 'bots.
* KillItWithFire: They somehow deduce that spider-Gary can only be destroyed with fire, so they drive him into quicksand by brandishing torches.
* LadykillerInLove: The movie appears to be trying to pull this off with Bob and Gladys, but the clumsy execution only succeeds in making Bob look like an indecisive JerkAss.
* LegoGenetics: They don't even bother to explain how or why radiation makes spiders mutate, or why their bites turn you into a werespider. Other than uranium deposits being nearby, and that's barely a HandWave.
* LoveAtFirstSight: Minutes after her first meeting with Bob (which involved him grabbing her while she was skinny-dipping), Gladys begins to consider marrying him.
* MonsterMisogyny: Kind of hard to avoid when the only two other guys come to the island in the last third of the film - and Gary is the first victim.
** The Professor is the first victim in an offscreen death.
*** Which means 3 of the 4 men on the island end up getting killed...
* MoodWhiplash: The girls escape the island to some easy-going music, then "THE END" abruptly appears on a black screen, accompanied by a creepy, dissonant music cue.
* NoEnding: Well, sort of. There's a shot of the girls leaving the island on a boat, then the film just... stops.
--> '''Tom''': So, you want to end your movie ''that'' way, huh? Okay, get bent, we're outta here.
* NoExceptYes: "There's absolutely no reason yet to fear the worst. Until now, we only know that the plane caught fire and we've lost radio contact."
* OfficialCouple: Gary was closer to Georgia than a boss and secretary normally are until Gary got spiderized.
* OffscreenCrash: The plane crash. One moment the plane is coming down, a few ocean scenes later they're all on the raft.
* PlotArmor: The only way that only the females and the talent agent were able to survive the flaming, nose-down, off screen plane crash - with nary a scratch, while the pilot, and any other crew or passengers don't survive.
* QuicksandSucks
* RomanticTwoGirlFriendship: Two of the dancers seem to have this going on.
* TheScourgeOfGod: Spider-Gary's first victim is the lone stripper of the group, who previously threw herself at Gary and only managed to get slapped by an angry Georgia.
* {{Sexophone}}: Heard whenever one of the dancers acts sexy, even when she's by herself.
* ShowSomeLeg: TheMovie. During the odd auditions for dancers, it's the first thing Gary asks of the first dancer. Which gets her a job. Something tells us that he's not hiring ''dancers'' to go to ''Singapore''. The one classically trained dancer ''gets turned away''.
* SmartBall: When the group finds a hammer, Gary correctly says that since it's got a long handle it's a mining hammer, probably used for mining radioactive elements like uranium.
** One of the dancers then [[IdiotBall asks if you can eat uranium]].
* SoftWater: Because it's easy to survive a plane falling nose-first into water, uninjured.
* WhyDidItHaveToBeSnakes: The only thing spiderized Gary shows any fear towards is fire. The second a torch is lit, he flees in terror.
* YouCanLeaveYourHatOn: Linda strips to her unmentionables during her "audition" as a "dancer".
