i saw this movie in the theater when it come out and which would have make me only seven year old . wow . some have describe it a a horror film . i do not think it be that gory and but some people might think it so . it certainly be s c a r y with the swarm bat . not scary enough to give a seven year old nightmare and but certainly thrilling and enough to keep most viewer on the edge of their seat . maybe a sci fi thriller be more accurate . a bunch of unrelated people ( men and woman ) be drug and kidnap and and throw into a high tech underground bunker and where they be tell via a remote video screen and that they will be hold in this stainless steel complex for year and rid out the apocalypse in a bid to repopulate the earth . spoiler . actually and this be all a lie . they be the subject of a manipulative psychological experiment where people be the lab rat . but and a monkey wrench be throw in the work and in the form of ravenous vampire bat that eat their way through the wall and attack the people in the lab complex . of course and no contact with the outside world be possible and a the complex be seal and be on a timer lock and which would not open for a month and say the one government spook on site and who know the whole set up be a scam . now and the mission be to escape before the bat kill everyone . can they do it and or will everyone die in a hail of blood . spoiler over . at the time i have not see every single twlight zone episode and so the twist actually do blow my little mind . ( twlight zone use to actually frighten me around that same time a well and whenever i do occasionally catch a rerun of that ) . this movie vanish off the face of the earth for year . but quite recently and i do manage to pick up a ( not exactly official ) copy of it on dvd . look at it again and i be shock that i remember so much of it . one thing that surprise me be the woman who appear on the giant video screen explain the situation be former los angeles newscaster kelly lange . i have be watch her ( and be annoy by her ) on tv since i move to l. a. in 1989. diana muldaur and a favorite from star trek ( both original series and tng ) be good in this movie as well . over the year i would think about this film from time to time and and it unique and claustrophobic atmosphere of doom and and this certainly hold up . upon further viewing and it really be a cool little flick . the only part i misremember be the fact that they reveal the surprise to the kidnapees about halfway through the film and and i have think that the deception wasn not reveal until almost the end . a creepy sci fi horror hybrid that i recommend highly to anyone who can find it . update 9/2007 represent 20th century fox be release a legitimate dvd of this film just in time for halloween 2007. hurrah . i highly recommend this movie and go out and get it . update represent i get the dvd . nice remastering job and great picture and sound and reasonably low price . no extra and though . highly recommend the dvd . great obscure sci fi movie and lot of nostalgia for me .
