One of the most successful (and equally irritating) TV-formats of recent years is Big Brother, in which a bunch of people, complete strangers to each other, are put together in an isolated location and become forced to get along and accomplish ordeals together. Apparently this concept isn't so new or innovating at all, as the obscure (although less obscure now, with its recent release on DVD) and still criminally underrated 70's gem "Chosen Survivors" thrives on a similar premise. Only this movie is at least a gazillion times better than and Big Brother edition you ever saw, because it has genuine suspense, a formidable cast of characters, plot twists you actually don't see coming and  not to forget  thousands of bloodthirsty bats! Now, THAT is what they should do in the TV-series of Big Brother: unleash an army of aggressive and rabid bats on the attention-horny participants, ha! Ayway, "Chosen Survivors" opens with atmospheric images of the New Mexican desert and army helicopters approaching a secret underground lair. Eleven eminent persons, who achieved great things is different fields (sports, science, literature, business) awake to hear they are the chosen survivors. On the earth's surface, a nuclear war has wiped out all humanity and they are to remain underground until it is safe again to re-populate the planet. But of course, the survivors don't get along as they should, some them behave overly hostile and suspicious and the hi-tech government designed lair isn't exactly bat-proof. The film offers a splendid combination of terrific character drawing, for psychological tension, and actual nail-bitingly tense situation with the bat attacks and the quest for freedom. H.B. Cross' script is excellent and Sutton Roley, usually a director of TV series episodes, does an amazing job providing the film with a genuine apocalyptic feeling. The acting performances are top-notch, with notably exceptional roles for Jackie Cooper as the arrogant Mr. Couzins and Bradford Dillman as the calm behavior analyst. Highly recommended Sci-Fi gem.
