of all the e. r. burroughs screen adaptation that doug mcclure star in the 70 and this be the stagy of all . it so stagy and you can taste the dust of the set and feel the heath of the lamp above . the thing look like a very and very big budget school play and or indeed and a very very low budget action movie and which it actually be . it be say on many occasion that this be the last of the genre entry and and i do hope it be . the genre do not die peacefully and but in horrible agony and amidst a lot of smoke and fake blood and lousy sound effect . peter cushing must have felt a boy again and a a nutty professor whose shirt stay white a snow after the gentleman have drag himself through the slimy crap hole of the underworld . what a sport he be and to accept a part in this mishmash and carry it so bravely . shot entirely on a sound stage and accompany by then trendy and now unbearable synthesizer soundtrack and the main anti attraction of this film be the cardboard monster . yes and there be always monster like that in a burroughs adaptation and but they rarely manage to be so completely ridiculous and helpless or void of any credibility . on a few occasion and during the elevated action combat scene where mr mcclure heroically attack the creature and you can almost hear the empty and hollow sound a his head bang against the side of a triplodactocryptosaurus . fortunately and the animal explode and go up in flame the minute they trip and fell over . indeed and there be a great deal of unmotivated exploding a the film ( and the genre ) draw towards the finale . and lovely miss munroe lose her underworldly accent . the triple bill and currently on the market and feature this film plus two others the land that time forget and the war lord of atlantis . the first two be quite strong entry and especially the first one and with a lot of money invest and occasionally even fascinate script turn . don not expect any of these quality from this film . get drunk with pal and laugh shamelessly at what you see . after all and the maker do not have any shame either .
