Did you see this movie 'The lost world' ?
I just saw this movie called 'The lost world' the other night. Michael Sinelnikoff is in it and he plays Summerlee. Challenger goes to a remote plateau in Mongolia with a lady Amanda White, a reporter Malone, a hunter John Roxton and there is also a Mongolian girl with them. Malone is the president of some hot air balloon club. He tells Challenger about how they can use a balloon to travel. They get to the plateau and they see the dinosaurs.
Eventually Roxton turns against them. He plans on becoming a millionaire from hunting dinosaurs. Challenger beats Roxton in the end though. Roxton blows himself up. Summerlee gets eaten by a dinosaur and Malone seems to get killed after the Mongolian girl gets eaten. Amanda and Challenger go back to England and proclaim that there are no such things as dinosaurs and that the rest of their companions were killed in the field. Later in the last scene we see Malone. He is still alive! He has become a wild man of the jungle. He is shown running around surviving carrying a large dinosaur bone. He writes his last notes in his diary and drops it off the cliff down below so that maybe someday someone will read it.
