This engaging adaptation is a special version of the Edgar Rice Burroughs adventure yarn . There are rip-roaring action, spirit of adventure, derring-do, thrills, and results to be quite entertaining. It’s a brief fun with average special effects , passable set decoration , functional art direction and none use of computer generator. Fantastic adventures full of monsters in a lost continent on the center of earth . Searching for adventures, a Victorian professor (Peter Cushing acting against his usual type as the absentminded scientific) and his American supporter named David Innes( an impulsive Doug McClure who has a good time) set off in their new boring rocket with a short proof on a Welsh mountain. Unfortunately the things were wrong and less easy than expected and they end up in a large cavern at the centre of the earth. When they’re watching how humans are dragged by an evil over-sized prehistoric bird , then they suddenly are attacked by a flying monster . It’s a domineering world governed by a monstrous race which rules the human beings with extra-sensory abilities. There they meet a race of humans enslaved , being one of them a gorgeous and eye-catching cavern-girl ( the scream-girl Caroline Munro from Hammer Productions as film’s chief attribute) in scantily clad .

This fantasy picture produced by Max Rosenberg and Milton Subotsky packs thrills, action, weird monsters, lively pace and fantastic scenarios. The rubber monsters are the real stars of this production ,however being middling made . The fable is silly and laughable , though the effects and action are regularly made . Among the most spectacular of its visuals there are a deeply shrouded caverns full of monsters roaring menacingly towards the camera , a little tableau comprising attack of a giant monsters and the colorful backgrounds of the lost land . Some monsters are clumsily made but movie is OK . Some illogical parts in the argument are more than compensated for the excitement provided by Roger Dicken’s monsters, though sometimes are a little bit cheesy. Filmed in glimmer and shimmer cinematography by Alan Hume in Pinewood studios , England , showing a colorful camp treat. Splendid and stirring musical score by Mike Vickers. This is the fourth collaboration between producer John Dark and director Kevin Connor who also made in similar style : ¨The land that time forgot(1975)¨, , ¨The people that time forgot(77)¨. ¨Warlord of Atlantis¨ , mostly starred by Doug McClure and with Dicken as the monster-maker. The film will appeal to adolescents who swallow whole and sit convulsed in their armchair. Older kids will enjoy the colorful sets and fire-breathing animals.
