History Film / OneMillionYearsBC

* InfantImmortality: Predator attacks menace children more than once, but the children are rescued. The adults aren't always so lucky. Averted with the baby animals. The Rhamphorhynchus, for instance, eats the baby Pteranodons after killing their mother.

* NatureIsNotNice: Boy, is it ever not. Just about all the creatures you'll meet will try to kill you, when they aren't trying to kill each other. The animals don't even get InfantImmortality, as we see in one disturbing scene.

* TitleByNumber: The 1966 Hammer Film Productions remake of 1940's ''One Million BC'', named for the year of events.

* AnachronismStew: The film pulls off the remarkable feat of including no creature who ''actually'' lived in one million B.C. -- not even the charismatic ones, like saber-toothed cats and terror birds. Apart from the ape-men, they're all Mesozoic or (frequently enlarged) modern animals.

* AllGirlsWantBadBoys: Despite his violent behavior, Loana is so stuck on Tumak that she follows him into exile.

* StockDinosaurs: Allosaurus, Ceratosaurus, Triceratops, and what was then called Brontosaurus all put in appearances. Token non-dinos include Pteranodon, [[InNameOnly what the film claims is a Rhamphorhynchus]] and Archelon.

* DisneyDeath: [[spoiler:Tumak sees the pterosaur eating something with its babies, believing the food to be Loana, but it turns out she survived the capture and later came back.]]

* ArtisticLicenseBiology: Though the AnachronismStew is the most obvious use of the license, another curious feature of the ecosystem as that it seems to be almost totally missing the bottom 90% of the food chain. The barren landscape (filmed in the Canary Islands) contains almost no plants or small animals, [[MorePredatorsThanPrey just one large predator after another]].

* CataclysmClimax: [[spoiler: The climactic fight between Tumak's and Sakana's factions is ended by a volcanic eruption and an earthquake, which kill most of the antagonists.]]

''One Million Years B.C.'' is the better-known 1966 remake of 1940's ''One Million BC'', which was the TropeNamer for the OneMillionBC image of cavemen, dinosaurs, ape-men and other real and made-up creatures of the past duking it out in a volcano-scarred landscape. The film provided a showcase for Creator/RayHarryhausen's stop-motion effects, as well as Creator/RaquelWelch's physique in her iconic FurBikini.

* VillainousRescue: More than once, a predator is distracted from attacking people by an attack from another one.

* ConLang: What little dialogue there is in the movie is invented (and untranslated) caveman speech. Though given the general standards of the movie, this is probably more a case of AsLongAsItSoundsForeign.

* ArtisticLicensePaleontology: And how. Lampshade by Ray Harryhausen, who remarked that he did not make the movie for palaeontologists and dino-nerds "who probably don't go to see these kinds of movies anyway."

* BlueAndOrangeMorality: The Cavemen don't really seem to have any sense of morality, being focused almost entirely on survival.The Shell Tribe don't like stealing but that's about it.

* DeathWorld :Prehistory is depicted as this. In addition to being a harsh and barren environment to begin with, its crawling with large , vicious predators who have an apparently insatiable desire for human flesh. Most of the sapient inhabitants aren't much better , with the Ape -Men and the Rock Tribe being savage and brutal.

* NothingIsScarier: We never get a good look at the ape-men,which makes them considerably creepier.

* Slurpasaur: One appears briefly, as a homage to the original film. The giant spider is also played by a real animal.
