Return to the Lost World (1992) on Netflix

Plot summary

Belgian scientist Bertram Hammonds reaches the Lost World with drilling equipment and puts the natives to work as slaves. Chief Palala is thrown from the top of the plateau, survives, and is carried by Malu to a nearby village. Word of this reaches England, and Edward Malone and Jenny Nielson hold Professors Challenger and Summerlee to a promise to return if the Lost World needs them. The two professors are feuding, however: Challenger recently discredited Summerlee over a theory, and the pair are not speaking. Malone and Jenny, aided by Jim, trick both men into joining the expedition, each believing he commands it while the other stays in England. On the steamship bound for Africa the professors nearly come to blows, and Malu leads the party to the base of the plateau.
