~Plot Synopsis~
When Edward E. “Ed” Malone, reporter for the Record-Journal in London, England, begs for a
“dangerous assignment” to impress his fiancée, managing editor Colin McArdle sends him to the
Zoological Hall, where Professor Challenger is presenting a paper to disbelieving students and faculty
that details his recent South American expedition. Challenger is antagonistic toward the press for
ridiculing his assertion that a “lost world” of prehistoric creatures exists on a nearly inaccessible
“great plateau” above the jungle. During his presentation, Challenger asks for volunteers to join him
on a new expedition to prove his claim and find his colleague, Maple White, who disappeared on the
plateau. Thanks to his friendship with big game hunter Sir John Roxton, Ed Malone convinces the
professor to include him on the expedition, and then gets the Record-Journal to finance the
expedition in return for exclusive story rights. Challenger introduces Ed to Maple White’s daughter,
Paula, who was in the Amazon when her father disappeared. She did not make it to the plateau due to
illness. Challenger, Roxton, Ed, Professor Summerlee, Paula White, her pet capuchin monkey named
Jacko, Challenger’s butler Austin, and an Indian named Zambo travel to the upper reaches of the
Amazon. Leaving Austin and Zambo below, the five, along with Jacko, climb to the plateau. All but the
capuchin are trapped when a brontosaurus tips their log bridge into a chasm. Penetrating the jungle,
the explorers encounter an apeman, a flying pteranodon, and dozens of lumbering dinosaurs. During
one of several battles between dinosaurs, a brontosaurus is pushed over a cliff and lands in a muddy
river below. Although John Roxton expresses his love for Paula, she is attracted to the much younger
Ed Malone, and they develop a relationship. When the explorers find safety in a cave from a vicious
allosaurus, John Roxton discovers Maple White’s remains, along with a pocket watch, which he gives
to Paula. He also finds a natural tunnel that ends midway down a cliff, where he is able to call out to
Zambo and Austin below. They send Paula’s capuchin, Jacko, scrambling up the cliff with a rope,
allowing the trapped explorers to pull up a ladder made of vines and make their descent, just as a
volcanic eruption sets the jungle on fire. Seeing the fallen brontosaurus stuck in the mud, Challenger
decides to bring in a dredge, cage the dinosaur on a raft, and float it down the Amazon during the
upcoming rains to prove to the world it exists. However, in London, the brontosaurus escapes when
its cage is dropped on the dock. The creature terrorizes the city and smashes buildings until its
weight collapses a section of the Tower Bridge, dropping it into the Thames River. As the dinosaur
swims toward the ocean, Ed and Paula ride off together in a cab, and John Roxton, always the
sportsman, wishes them well.
