tirelessly prolific veteran italian exploitation picture director antonio margheriti cinematic oeuvre be a very mixed bag and run the gamut from delightfully sleazy ( cannibal apocalypse ) to nice and spooky and drip with sepulchral atmosphere fright film fun ( the virgin of nuremburg and the long hair of death ) to entertainingly goofy sci fi ( the wild and wild planet and war between the planet ) to pleasingly tacky spaghetti western ( the stranger and the gunfighter and take a hard ride ) to the unavoidable occasional dud . this sci fi or horror or conspiracy thriller sadly constitute a one of margheriti dullest and least satisfying feature and mainly because it crucially bereft of the gleefully trashy verve which distinguish his more enjoyable effort . in it place there no sex or nudity and mild profanity and tame violence and an interminably draggy pace and a wearily draw out narrative and and tepid action sequence while in short and everything a solid and rewarding little b movie need to seriously smoke be noticeably absent here . the blah plot offer a tediously triten notired mishmash of boringly overuse clichés and center on your standard evil corporation illegally dump radioactive waste into a dangerously volatile volcano locate on a remote obscure island . two wet nose bleed heart liberal limp dishrag greenpeace worker discover the pernicious going on and spend the rest of the film be hunt down in the dense tropical jungle by the usual assortment of greasy company flunky . oh yeah and there a lethal and clawed and slime drooling and steam expel extraterrestrial subterranean creature the pair also uncover and do their best to protect from the conglomerate vile and greedy clutch . token semi name rugged and craggy face and firm block of granite character actor charles napier portray a typically malevolent nasty army colonel on thespic automatic pilot throughout and wear a fixed scowl on his puffy and roughhewn mug and grumble all his dialogue in a deep and earthy and barely audible rumble mumble . napier give precious little to do that worth see and an unfortunately malady that infect this dismally dreary clunker a a lethargic whole .
