When flying, some people worry about engine trouble or running out of fuel; the prospect of crashing into a Pterodactyl and falling into a volcanic crater is probably pretty low down on the list...we assume anyway! Unfortunately for the crew aboard this helicopter, who were on an expedition to Antartica, weren't too lucky. After crashing down to below sea-level into a steamy tropical jungle of dinosaurs and giant carnivorous plants, they encounter a human who had survived a plane crash during another expedition years before. They must find the remains of the long destroyed plane to repair their helicopter and escape before wintery conditions set in! This retro b-movie poster design features the original artwork from The Land Unknown showing the tropical jungle from the film with roaming dinosaurs and the trapped crew!
