Overview
The Lost World is a 1992 film, based on the 1912 novel The Lost World by Sir Arthur Conan Doyle. The movie is set in Africa rather than the book's setting of South America, and the character of Lord John Roxton has been replaced with a female character played by Tamara Gorski (in her film debut). It was followed by a sequel the same year, Return to the Lost World, with the same director and main cast.
Plot
The film opens on Edward Malone, a junior reporter looking for an adventurous assignment. Malone is sent to interview Professor Challenger, an explorer and researcher who believes he is on the trail of the "lost world," a mysterious place in Central Africa. Challenger has a picture of a cliff and a strange beast resembling a pterodactyl that is his only evidence of the place.
The British scientific community finds his claims laughable. After receiving funding from the family of Jenny Nielson, a wildlife photographer and the daughter of a rich American contributor to the sciences, the "scientific community" agrees to organise an exploratory expedition under the leadership of the antagonistic Professor Summerlee. Summerlee agrees to Malone and Nielson coming on the expedition, but refuses to allow Challenger to be part of the expedition. With obvious reluctance, Challenger gives Summerlee a "map" to be opened at a road-end village in Africa at a particular date and time. The expedition departs. A newsboy associate of Malone named Jim stows away on the trip.
The expedition arrives in Africa where they are joined by a female guide named Malu and a Portuguese called Gomez. Summerlee opens the map from Challenger, finding it blank, at which point Challenger appears from nowhere leaving Summerlee no option but to accept his guidance on the expedition. Under Challenger's guidance they find the cliff in the picture and reach the top, but Gomez (who turns out to be the brother of a Portuguese who was killed on Challenger's first journey here) strands them with no way back down. Exploring the Lost World to find another way home, the team finds dinosaurs, from a pair of Anatotitan to a pterodactyl rookery.
