series of nuclear bombs in western Siberia. Stenning, Maguire, and Jeanie gather at a bar to listen to the radio broadcast of the event. The bombs are detonated, and the shock wave causes dust to fall from the bar's ceiling. At the newspaper print room, two versions of the front page have been prepared: one reads "World Saved", the other "World Doomed". The film ends without revealing which one will be published, and in the words that talking Stenning where "humanity will recover after all this horror."

Production Val Guest said there was a lack of enthusiasm to make the film and he only managed to persuade British Lion to finance it by putting up his profits from Expresso Bongo as collateral. All the finance was British. The film was made in black and white but in some original prints, the opening and closing sequences are tinted orange-yellow to suggest the heat of the sun. It was shot with 35 mm anamorphic lenses using the French Dyaliscope process. Critic Doug Cummings said, about the look of the film, Guest also manages some visual flair. The film was shot in anamorphic widescreen, and the extended frame is always perfectly balanced with groups of people, city vistas, or detailed settings, whether bustling newsrooms, congested streets, or humid apartments. Although the film's special effects aren't particularly noteworthy, matte paintings and the incorporation of real London locations work to good atmospheric advantage (heavy rains buffet the windows; thick, unexpected fog wafts through the city; a raging hurricane crashes into the British coast). Guest also cleverly incorporates stock footage to depict floods and meteorological disasters worldwide. The visual style of the film is straightforward
