Professor Challenger (Claude Rains), a famed biologist and anthropologist, reports to the London Zoological Society that he has discovered living specimens of supposedly extinct animals, including dinosaurs, on an expedition to the Amazon Basin. When his colleagues dismiss his claims, he challenges the Society to mount another expedition to verify his story. Challenger and his companions travel to an isolated plateau, where they encounter prehistoric creatures and other hazards, and discover the legacy of a previous explorer that reveals the hidden past of one of their team. During a volcanic eruption, they escape from the plateau carrying the egg of a Tyrannosaurus rex. The egg hatches when it is dropped by accident, and Professor Challenger decides to take the infant dinosaur back to London with them.
Près des Îles Caraïbes, des dinosaures échappent à une éruption sous-marine et sèment la terreur auprès de la population. Au même moment, un homme de Néandertal se lie d'amitié avec un petit orphelin...
The movie is about American men building a harbour on a Caribbean island when they accidentally uncover two dinosaurs that have been frozen in suspended animation for millions of years. They are a Brontosaurus and a Tyrannosaurus rex. That night, during a storm, the beasts are struck by lightning and come back to life. The islanders have no idea that the dinosaurs are alive because of the storm and are now roaming the island. Also awoken is a caveman (played by Gregg Martell) who befriends Julio, an island boy, and along with the Brontosaurus get into a series of wacky misadventures, which lead to the death of the Brontosaurus and the caveman. Meanwhile, the islanders have found refuge from the Tyrant Lizard King by hiding in the old fortress, which is protected by a ring of burning fuel. To ensure the Tyrannosaurus does not get in, the hero Bart (played by Ward Ramsey) drives out to face the beast in a mechanical digger. The two duel on the edge of an island cliff and, after a tense fight, the Tyrannosaurus is knocked into water, ending the island terror. The film ends with a picture of the apparently dead Tyrannosaurus on the sea bed, with 'THE END' followed by '?' superimposed. Even though the movie ended with a question mark, there was no sequel.
In Edinburgh, Scotland, in 1880, Professor Sir Oliver Lindenbrook (James Mason), a geologist at the University of Edinburgh, is given a piece of volcanic rock by his admiring student, Alec McEwan (Pat Boone). Deciding that the rock is unusually heavy, Lindenbrook, mostly thanks to the carelessness of his lab assistant, Mr. Paisley (Ben Wright), discovers a plumb bob inside bearing a cryptic inscription. Lindenbrook and Alec discover that it was left by a scientist named Arne Saknussemm, who had, almost 300 years earlier, found a passage to the center of the Earth. After translating the message, Lindenbrook immediately sets off with Alec to follow in the Icelandic pioneer's footsteps.
American scientist Steve Karnes (Gene Evans) delivers a speech to a British scientific society, headed by Professor James Bickford (André Morell), about the dangers to marine life posed by nuclear testing. Before Karnes can return to the U.S., a real-life example of his concern materializes when Tom Trevethan (Henri Vidon), an old fisherman, receives a lethal doze of radiation; his dying word is "behemoth". Later thousands of dead fish are washed ashore.
A tribe of primitive humans lives in a barren, rocky wasteland and struggle for survival, despite a lush, plant-filled land on the other side of a nearby river. They refuse to cross the river because of a law that evolved from an ancient tale warning of a god lurking there who brings death with a single touch.
A rare species of butterfly native to Siberia is found in a mysterious valley in Japan, a pair of entomologists go to investigate. In response, an expedition is dispatched to their habitat, located along the Kitakami River, to discover why the insects might be living in Japan. Two members of the scientific community helm the expedition, but are mysteriously crushed by something that the police can only describe as "powerful." The nearby villagers of the Kitakami River insist that the deaths were a result of the wrath of their mountain god Baradagi-Sanjin.
A small crew led by Commander Harold Roberts and reporter Maggie Hathaway are on an expedition into Antarctica for the United States Navy. During a helicopter flight, they are called back to their ship via radio because of an unexpected storm approaching. At first they try to fly around the storm, but low on fuel, they fly into the storm, where they almost collide in mid-air with a man-sized pterosaur. Their rotor breaks and unable to stay in the air they start to descend, and are surprised when they end up landing well below sea-level in a warm volcanic crater. Inside, they discover a steamy tropical jungle populated by living dinosaurs, giant flesh-eating plants, and fresh human footprints. The crew encounter many dangers and perils in the jungle in a fight for survival.
American reporter, Steve Martin (Raymond Burr), is brought to a hospital with dozens of maimed and wounded citizens. In flashback, Martin recalls stopping over in Tokyo, where a series of ship disasters catches his attention. When a survivor finally washes up on Odo Island, Martin flies there for the story with Tomo Iwanaga (Frank Iwanaga), a representative of the Japanese security forces and learns of the island inhabitants' belief in a sea monster god known to them as "Godzilla", which they believe is causing the disasters.
In the small mining village of Kitamatsu, on the southern Japanese island of Kyushu, two miners have gone missing. The two men, Goro and Yoshi, had brawled earlier that day, and after they entered the mine to start their shift, the shaft had quickly flooded. Shigeru Kawamura (Kenji Sahara), a tunneling and safety engineer at the mine, heads below to investigate and makes a gruesome discovery: Yoshi's lacerated corpse. Above ground, a doctor examines Yoshi, and discovers the cause of death to be a series of deep gashes caused by an abnormally sharp object. Some of the miners and their families begin to discuss the possibility of the involvement of Goro, who is still unaccounted for, in the death. Shigeru is personally affected by this incident, since his fiancée Kiyo (Yumi Shirakawa) is also Goro's sister.
In southern Mexico at the turn of the 20th century, tales are told of cattle and farmers mysteriously disappearing. These events occur at a location called "Hollow Mountain" where a curse is supposed to be residing. The mountain has never been explored and the swamp at its base is said to claim the lives of anyone foolish enough to go to its banks. In spite of these tales and possible perils, American cowboy Jimmy Ryan leads three cowboys into the area in search of lost cattle. When they arrive they find mysterious tracks and believe the curse from Hollow Mountain is responsible. Whilst trying to track the curse down one of them falls into a tar pit at the base of the swamp and nearly drowns, but is rescued.
Two pilots named Shoichi Tsukioka and Koji Kobayashi are hunting for schools of fish for a tuna cannery company in Osaka. Kobayashi's plane malfunctions and is forced to land near Iwato Island, an uninhabited strip of rocks formed by volcanic eruptions. Tsukioka then looks for Kobayashi and finds him safe, with only a wrist sprain. While talking, the two men hear some strange sounds and find two monsters fighting. Tsukioka immediately recognizes one of the monsters to be Godzilla. The two monsters then fall off a cliff, into the ocean.
The story involves four teenage comrades who take a rowboat along a "river of time" that flows into a mysterious cave and emerges on the other side onto a strange, primeval landscape. The boy actors were Josef Lukáš (Petr, the main narrator), Petr Herrmann (Toník, who also narrates in part), Zdeněk Husták (Jenda), and Vladimír Bejval (Jirka). As they make their way upstream, they realise that they are travelling progressively farther back in time, and facing various perils as they do so (but learning much about prehistoric life in the process). The animals depicted in Cesta do pravěku were never shown interacting with animals of other periods and it is assumed that different parts of the river represented distinct time periods. The plot is somewhat similar to that of the novel Plutonia (1915) by the Russian palaeontologist Vladimir Obruchev, in which a team of Russian explorers enter the Earth's crust via an Arctic portal (a huge depression in the Earth surface created many millions of years previously by the impact of a giant asteroid, into which prehistoric animals had entered), and follow a river that leads them through a sequence of past geological eras and associated animal life. Some scenes in Cesta do pravěku recall Arthur Conan Doyle's 1912 novel The Lost World, with four male protagonists exploring a prehistoric world where they find evidence of native human habitation, are attacked by a group of enraged pterodactyls, witness a twilight fight between a carnivorous dinosaur and a herbivorous one, encounter a Stegosaurus up-close, and see one of their members (Petr) pursued by a Phorusrhacos.
Four astronauts in 1960 travel to a planet called Nova that has just entered Earth's solar system. The crew begins studying the planet to see if it's suitable for a possible Earth colony. After first discovering normal Earth animals such as a kinkajou and an alligator, they soon encounter and battle giant insects, an enormous snake, prehistoric mammals, dinosaurs, and - on an island - the titular character, King Dinosaur, a putative Tyrannosaurus Rex. Eventually, the scientists blow up the island with an atomic bomb, killing all of its inhabitants.
