Germans and Americans aboard a submarine discover an island full of prehistoric monsters. This was the most ambitious movie made by the British film company Amicus, who specialized in horror and fantasy films in the early Seventies. Rediscover The Land That Time Forgot, a lost world with Dinosaurs, hostile tribes and deadly wildlife in this much loved Sci-Fi Classic. When a German U-Boat torpedoes a British supply ship, the survivors manage to swim to the surfacing German vessel. Among the survivors are Bowen Tyler (Hollywood superstar Doug McClure) a young allied soldier and a young biologist Lisa Clayton (Susan Penhaligon). They manage to force their way onto the ship and overpower the German crew. Despite sending signals to an allied ship that they have commandeered the German vessel, they are depth charged and forced to allow the German crew to steer the vessel to rendezvous with a German supply boat. They drift of course and find a strange island. Whilst investigating what the island has to offer the crew are attacked by a huge pre historic monster and a tribe of primitive humans. Lisa is kidnapped in the fight and Bowen rushes after the tribe to rescue her. When a huge volcano erupts Bowen’s plight to rescue Lisa becomes even more desperate. Can he save them and get back to the Submarine before they are killed by the oncoming lava?
