1977 action-adventure film in which a drilling expedition unexpectedly finds a LostWorld deep below the [[MysteriousAntarctica North Pole]]. Big game hunter and oil tycoon Masten Thrust is determined to hunt his last and ultimate predator, a ''Tyrannosaurus rex'' that killed nearly the entire first explorer group. Ultimately the team becomes trapped in the lost world and must try to survive against the T. Rex and vicious cavemen. This film was a co-production between Rankin/Bass (best known for the stop-motion ''Rudolph the Red-Nosed Reindeer'' special) and Tsuburaya Productions (best known for Ultraman and its countless spin-offs).
!!You ding-dong! This is a list of tropes associated with this film:
* ArtisticLicensePaleontology: There are a lot of inaccuracies you can point out, most egregious being the ''Uintatherium'' (a prehistoric rhino-like mammal) that attacks the group shortly after their arrival, which Chuck identifies as a "ceratopsian" (the group of horned dinosaurs that ''Triceratops'' belonged to). This is especially hilarious considering earlier in the film Chuck claimed to have taken a year of vertebrate paleontology.
* DoubleMeaningTitle: ''The Last Dinosaur'' refers to not just the ''Tyrannosaurus'', but also Masten Thrust. Lampshaded when he acknowledges this himself.
* ElephantGraveyard: The Tyrannosaur's SuperVillainLair is a valley boneward of all the things its killed and eaten.
* GreatWhiteHunter: Masten Thrust, complete with a black tracker to carry his rifle for him.
** TheHero: Thrust, even though he's much more of an anti-hero.
** TheLancer: Banks the photographer.
** TheBigGuy: Bunta the Masai tracker.
** TheSmartGuy: Dr. Kawamoto a, well, scientist. Wade is also a geologist and knows most about the dinosaurs but is...
** TheChick: Wade, who honestly is the whiniest of the group.
* LargeHam: Richard Boone is an absolute delight as he chews up the scenery. Reportedly he was heavily drinking while filming and even drunk during some scenes.
* LastOfHisKind: The ''Tyrannosaurus'' is assumed and said to be this, and Thrust also declares himself as such, giving the film it's DoubleMeaningTitle.
* PeopleInRubberSuits: Well the effects were Japanese-made, and what are they most famous for?
* ReliablyUnreliableGuns: Big game hunter Masten Thrust throws away his hunting rifle after it jams while trying to shoot a Tyrannosaur that's about to attack them. Not only does he make no effort to clear the jam, but he never even tries to get the rifle back later (he has the perfect opportunity to pick it back up later, but instead only takes the scope to put on his new crossbow). The fact that he's both a lifelong hunter ''and'' a firearms collector makes this all the more implausible.
* OmnidisciplinaryScientist: Chuck, who is nominally a geologist, exhibits expertise in zoology, paleontology and botany. Likewise Kawamoto is both a machinist/engineer, geologist and botanist.
* StockDinosaurs: A ''Tyrannosaurus'' is the main star, also with an appearance by a ''Triceratops'', complete with a showdown between the two. ''Pteranodon''s also make several appearances.
* TheVoiceless: Bunta. Though Thrust says he is "very articulate if you happen to speak his language", he is never heard saying a thing in any language.
* TyrannosaurusRex: Paleontologists have called them the crown of creation...the king of the super tyrant lizards!
* UnintentionalPeriodPiece: Hmm, judging by the clothes and especially the music, it's a good guess this was made in the 1970's.
