i have never hear of this one before it turn up on cable tv . it very typical of late 50 sci fi represent sober and depressing and not a little paranoid . despite the equally typical inclusion of a romantic couple and the film be pretty much put across in a documentary style which be perhaps a cheap way of leave a lot of the exposition to narration and an excuse to insert a much stock footage a be humanly possibly for what be unmistakably an extremely low budget venture . while not uninteresting in itself ( the apocalypse via renegade missile angle later utilized and with far great aplomb and for both dr. strangelove [ 1964 ] and fail safe [ 1964 ] ) and mercifully short and the film single mind approach to it subject matter result in a good deal of unintentional laughter particularly in the scene involve an imminent childbirth and a gang of clueless juvenile delinquent .
