the world a we know it and be about to end . total thermonuclear destruction represent 4 billion casualty and 168 survivor and 12 hi tech underground facility spread across the usa at a depth of 1 . 758ft and one locate in the new mexico desert inhabit by 11 unsuspecting citizen on government command with their sole purpose the survival of the human race . but our group of chosen survivor will soon have something else to worry about than the lethal radiation level above their head represent desmodus rotundus and commonly know a the vampire bat . choose survivor be one nifty 70 post nuke paranoia thriller . the opening scene already look promising represent 11 sedate citizen be fly in by helicopter over the ominous desert landscape and accompany on the tune of a tense brass score . in slow motion they be shove into an elevator and when it start to go all the way down and the opening credit come on and slow motion shot of the elevator rattling and shaking continue . great stuff . once inside the facility and the survivor learn about their faith . the character be all well draw out and each of them have an expertise in a certain field ( science and sport and write and ) . they will all have to get along and work together in order to survive and but needless to say tension arise and conflict occur . all that be pretty entertain already and but the real fun start when they discover a vampire bat inside the facility . they realize that a whole horde of hungry killer bat be lurk inside the cave surround the facility . and paranoia turn into survival . psychologically and the character be also well think out . naturally and there one guy you love to hate that eventually do something very stupid and but even his character change throughout the movie . so and all in all chosen survivor be pretty unpredictable when it come to who will survive and who would not and if any . the set design and of course and look date but nevertheless be a well construct concept for those day . the bat attack be stag in a decent fashion . good thing be that they actually use a lot of real bat in certain scene and instead of go for the obvious fake one . the blue screen effect be obvious in certain scene and but always effective . aside from the survival horror element with the bat and choose survivor be a bit more in the sci fi or thriller vein of other 70 paranoia or conspiracy movie like and for instance and capricorn one . only this time with nobody be hunt down and but the whole group be trap deep below ground . a to be expect and the facility isn not all that big ( limited budget and limited set ) and but the location be put to good use . with the look and feel be obsolete and chosen survivor actually could inspire a decent remake and in my opinion . just replace the global nuclear devastation angle with that of the ever so popular killer virus one and put the whole concept in capable hand with a decent budget for a skilled crew and up to date special effect support by a good cast and et voilà and we should have a remake that far more decent than the uninspired crap they keep crank out nowadays . no need to change the script even and because it already contain a decent twist around the middle part and which in today suspense cinema have become a must . actually and they might want to make the bat virus infect this time and because how in this film they manage to kill off adult in a couple of minute with a dozen bite or so and be beyond me . other than this shortcoming and the script successfully blend genre . a typical 70 accomplishment on the one hand and and ahead of it time on the other . check this one out . it a gem .
