Not the cheeriest of sci-fi films this, which is probably the way it should be. However, it does feature Leo McKern and Bernard Braden involving themselves in much Hold-The-Back-Page-style newspaper witticisms. And the bloke who played who plays the editor had actually been the editor of the Daily Express, fact fans. Much tumbling around sweatily in amongst the mists in London by Edward Judd and Janet Munro as the Earth is knocked off kilter by ill-advised nuclear tests. It’s a great film but don’t watch it whilst pondering any important decisions as it is likely to radically alter your sense of perspective.
