The Lost World (1960 film)
The Lost World is a 1960 American fantasy adventure film directed by Irwin Allen, loosely based on the 1912 novel of the same name by Arthur Conan Doyle. Shot in De Luxe Color and CinemaScope, the film's plot revolves around the exploration of a plateau in Venezuela inhabited by cannibals, dinosaurs, carnivorous plants, and giant spiders. The cast includes Claude Rains,
David Hedison, Fernando Lamas, Jill St. John, and Michael Rennie. Plot
Professor Challenger, a celebrated 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 and up a barely known plateau. He challenges the Society to sponsor a second expedition to the plateau. Much to Challenger's dismay, he attracts a few very unscientific people to join him on his second journey to the Amazon. This expedition group includes big-game hunter Lord John Roxton, and newsman Ed Malone whose publisher advances $100,000 to pay for the expedition. The publisher's adventurous daughter Jennifer and son David join the group at the head of the Amazon. Also in the group is Zoological Society bigwig Professor Summerlee, helicopter pilot Manuel Gomez, and his sidekick Jose Costa. During the first night on the plateau, a dinosaur wrecks the helicopter. As the expedition proceeds, Malone chases a primitive jungle girl through cobwebs to a giant spider, killing it and bringing her back to camp. The native girl later falls for David. Roxton argues with the others, and jealousies over Jennifer lead to a fistfight between Malone and Roxton. They discover the diary of a previous explorer, Burton White, who was lost on the plateau. Roxton is mentioned several times in the diary. Roxton reveals that he had visited the plateau three years before, and claims the plateau holds a bounty of diamonds. This motivates Jose to stay with the party instead of striking out on his own to escape from the plateau. At one point, Malone and Jennifer are separated from the others and have a near-death encounter with two battling dinosaurs. Cannibals capture the party, but before they can become dinner the jungle girl leads them to an underground passage that leads down off the plateau. Along the way, they encounter Burton White, now living as a blind hermit. (The cannibals have a taboo against killing the blind.) They encounter more obstacles — pursuit by the cannibals, spider plants, the "Graveyard of the Damned", and a dinosaur in a lava pit guarding the diamonds, which kills Costa. Gomez sacrifices himself while breaking a rock dam, killing the dinosaur. During a volcanic eruption, the survivors of the Challenger party escape from the plateau, Challenger carrying the egg of a Tyrannosaurus rex. The financial security of the party is secure because Lord Roxton filled a couple of the bellows pockets of his hunting jacket with diamonds, and shares them with everyone. The dinosaur egg hatches when it is dropped by accident, and Professor Challenger decides to take the infant T. Rex back to London with them. Featured cast

Production
In 1959, Allen purchased the rights to Doyle's novel for $100,000. He wanted to make the film with Trevor Howard and Peter Ustinov in support of Rains, as well as Victor Mature and Gilbert Roland (who had been in the 1925 film). None of these plans came to fruition. He hired Charles Bennett to help him adapt the book into a script and commissioned Willis O'Brien, who worked on the 1925 film, to do the models. He said he wanted to start filming on 15 October 1959. Allen eventually received financing to make the film from Buddy Adler, head of production at 20th Century Fox. Special effects for the film were rather basic and involved monitor lizards, iguanas, and young crocodiles affixed with miniature horns,  and fins. Director Allen later stated that though he wanted stop motion models, he could only work with live animals in accordance with the studio's budget. Critical Appraisal
Film critic Dana M. Reemes registered this assessment of the film in 1988:

Reemes added this caveat: “On the positive side, one might regard this film’s mere existence as a powerful incentive to create a new and definitive version of Conan Doyle’s original story.”

Legacy
Irwin Allen utilized stock footage from this film for episodes of his various TV series, including Land of the Giants, Lost in Space, The Time Tunnel, and Voyage to the Bottom of the Sea. In 1966, Irwin Allen even tried to sell a TV series based on the film, as he had done with Voyage to the Bottom of the Sea, but was unsuccessful. Stock footage was also used in the movie When Dinosaurs Ruled the Earth (1970). Comic book adaptation
