Seven Days To Noon (UK-import)
Oscar-winning thriller from the Boulting Brothers. When a scientist, Professor Willingdon (Barry Jones), sends a letter to 10 Downing Street threatening to blow up the Houses of Parliament within a week unless the Prime Minister agrees to his demands, it is dismissed as a hoax. But when Willingdon disappears, alarm bells start to ring, and soon the whole of London is out looking for him.
