History Film / TheLostWorld

* BeastMan: Apeman.

* EverythingsBetterWithMonkeys: Jocko.

* ImprobableTaxonomySkills: The explorers are able to identify the dinosaurs to the precise genus all while looking at them from a distance, despite them only having seen dinosaur skeletons and so they should not know precisely what the real versions would look like—especially considering the millions of years of evolution in the interval, as well as the fact that only a handful of dinosaurs had been discovered back then anyway. [[ScienceMarchesOn (To say nothing of feathers.)]]

* {{Kaiju}}: The very first. That ''Brontosaurus'' going on a destructive rampage through London was such a trendsetter. It predates ''Film/KingKong1933'' by 8 years and ''Film/{{Gojira}}'' by 29.

* AdventurerArchaeologist: Professor Challenger.

* BridgeLogic

* AnimalSidekick: Jocko is a pet capuchin monkey who accompanies the expedition.

* RoarBeforeBeating: The ''Allosaurus'' is stalking a grazing ''Trachodon'', but instead of pouncing on it, it roars at it from behind, as if it was challenging it for a fight.

* EscapedAnimalRampage: May have been TropeNamer as far as monster movies are concerned.

The movie was produced by Creator/FirstNationalPictures, a large Hollywood studio at the time,[[note]]They eventually merged with Creator/WarnerBros[[/note]] and stars Creator/WallaceBeery as Professor Challenger. This version was directed by Harry O. Hoyt and featured pioneering stop motion special effects by Willis O'Brien (an invaluable warm up for his work on the original ''Film/KingKong1933'' directed by Merian C. Cooper and Ernest B. Schoedsack). Writer Doyle appears in a frontispiece to the film. In 1998, the film was deemed "culturally, historically or aesthetically significant" by the Library of Congress and selected for preservation in the United States National Film Registry. The film can be seen [[https://www.youtube.com/watch?v=dIgzh6OPYQQ here]].

Not to be confused with the 1997 movie ''Film/TheLostWorldJurassicPark'', which borrows quite a few plot points to ''The Lost World''.

* BringItBackAlive: The expedition brings back a brontosaurus that survived the volcanic eruption.

* DumbDinos: Most of the dinosaurs spend their screentime attacking and killing each other and humans, including the herbivorous ''Brontosaurus''. However, a moment with a parent ''Triceratops'' and its young averts the trope.

* {{Kaiju}}: The very first. That brontosaurus going on a destructive rampage through London was such a trendsetter. It predates ''Film/KingKong1933'' by 8 years and ''Film/{{Gojira}}'' by 29.

* PteroSoarer: The first prehistoric creature shown in the film is a massive pterosaur that grabs a peccary and carries it to its perch to eat.

* StockDinosaurs: For sauropods we've got ''Brontosaurus'' and ''Brachiosaurus''. For predators we've got an ''Allosaurus'' and a ''TyrannosaurusRex''. Other herbivores include ''Stegosaurus'', ''Triceratops'' and ''Trachodon'' (Now ''Edmontosaurus''). There's also the aforementioned ''Pteranodon''/''Pterodactyl''. There's one non-stock dinosaur that deserves special note. ''Agathaumas'' today is a synonym for ''Triceratops'', but here it was a separate animal, using Charles R. Knight's illustration as a guide. It gets the big fight scenes against the two large predators rather than ''Triceratops''.

''The Lost World'' is a 1925 silent film adaptation of Creator/ArthurConanDoyle's 1912 [[Literature/TheLostWorld1912 book of the same name]]. The movie was produced by First National Pictures, a large Hollywood studio at the time, and stars Wallace Beery as Professor Challenger. This version was directed by Harry O. Hoyt and featured pioneering stop motion special effects by Willis O'Brien (an invaluable warm up for his work on the original ''Film/KingKong1933'' directed by Merian C. Cooper and Ernest B.

* IJustWantMyBelovedToBeHappy: This seems to be reason why Roxton lets Paula go when she professes her love for Malone.

* DoesntGetTheGirl: The whole reason Malone went on the expedition was to impress Gladys, who marries Percy Potts while he's away. He does however win the hand of Paula - but since Paula was engaged to Roxton, now it's ''Roxton'' who doesn't get the girl.

* DoesNotGetTheGirl: The whole reason Malone went on the expedition was to impress Gladys, who marries Percy Potts while he's away. He does however win the hand of Paula - but since Paula was engaged to Roxton, now it's ''Roxton'' who doesn't get the girl.

* BreakTheCutie: Paula is teased with the possibility that her father might still be alive, then falls for Ed, only for her father's corpse to be found later and Ed to have a fiance.

* CallToAdventure: Ed, who's looking for a way to prove himself as a real man, boldly accepts Professor Challenger's invitation to journey to the depths of the Amazon.

* CanonForeigner: Maple White was given a daughter as a love interest for Roxton (and then Malone who unintentionally steals her from him). She contributes almost nothing else.
* CringeComedy: When Ed goes into his employer's office looking for a dangerous assignment, he immediately spills a bottle of ink all over a desk covered in papers, tries and fails to clean it up with a handkerchief, which he then wipes his face with, covering himself in ink as well, and on his way out he slips and falls headfirst through a closed door.

* FrazettaMan: the expedition is stalked by an ape-man portrayed by an actor in a furry suit and makeup, and his buddy who's just a normal chimpanzee.
* GentlemanAdventurer: Sir John Roxton
* IntrepidReporter: Edward Malone

* PteroSoarer: the first prehistoric creature shown in the film is a massive pterosaur that grabs a peccary and carries it to its perch to eat.
* PublicDomain: while certain restored version of the movie are owned by the organizations that oversaw them, the heavily-edited 60-minute version is in the public domain and can be found for free in many places online, usually without color tinting and featuring generic music.
