Fan Casting Sir Arthur Conan Doyle's The Lost World

"At the dawn of the 20th century" a band of British adventurers, led by adventurer and scholar Professor George Challenger, embark on an expedition to prove the existence of an isolated lost world. The team, consisting of a mismatched group of enthusiasts with less than selfless reasons for making the journey, begin their trip under less than ideal conditions. The members are Challenger, Professor Arthur Summerlee, Marguerite Krux, Major Lord John Richard Roxton and Edward T. Malone. Their hot air balloon crashes in the Amazon rainforest on an uncharted plateau where prehistoric creatures survive. The group is assisted by a young jungle-savvy woman named Veronica Layton, whose parents disappeared eleven years before. Her family was part of a research group known to have vanished under mysterious circumstances. Together, the group fights to survive against carnivorous dinosaurs, vicious Neanderthals, a race of lizard men, and other perils as they search for a way to escape.
