This was the first sound version of the Lost World and I think it is one of the best. The silent, 1925 movie is the best. There have been several remakes since this one.
Professor Challenger takes a party to an uncharted plateau where dinosaurs still roam. They arrive there by helicopter, but not long after they get there, this is destroyed by a dinosaur. Despite this, they explore the land and capture a native cave girl, who knows how to use a gun. We learn that Lord Roxton has been here on a previous expedition and he killed Gomez's brother. After a fight between two dinosaurs, the party are captured by unfriendly natives, who are cannibals. Luckily, the cave girl who the party captured earlier helps them to escape and after meeting Burton White, the blind surviver of an earlier expedition, make their way along a narrow ridge where Challenger nearly meets his death. The party collects some diamonds and then Gomez holds everyone hostage as he wants Lord Roxton dead, but the gun shot wakes the "fire monster" and it eats Costa. Gomez then meets his death by falling in the lava helping to open a rock door. The plateau then blows its top and everyone is safe. But one last explosion causes the dinosaur egg they found to fall on the floor and break, revealing a baby T-Rex...
The "dinosaurs" in this movie are enlarged lizards with fins and horns attached to them and an enlarged crocodile. This what director Irwin Allen wanted unfortunately. Pity he did not want stop-motion, despite Willis O'Brien helping with the special effects. We also see a giant spider and man eating plants.
The movie has a great cast: Claude Rains (The Invisible Man), Michael Rennie (The Day the Earth Stood Still), David Hedison (The Fly, Voyage To The Bottom Of The Sea) and Bond Girl Jill St John (Diamonds Are Forever).
I enjoyed this movie, despite the non stop-motion dinosaurs.
Rating: 4 stars out of 5.
