The Day the Earth Caught Fire

The Day the Earth Caught Fire is a 1961 British science fiction disaster film directed, produced and co-written by Val Guest with Wolf Mankowitz, in which simultaneous American and Soviet hydrogen bomb tests knock the Earth off its axis and set it drifting toward the sun.¹ The story is told from the newsroom of London's Daily Express, where reporter Peter Stenning (Edward Judd) breaks the story and investigates a government cover-up while temperatures rise.² The film won a British Academy Award for best screenplay and is regarded as one of the strongest British science fiction films of its era.³

Plot

The film opens with a framing scene in which Stenning walks through deserted London streets, not knowing whether he is witnessing the end of the world; the action then moves back a month to just after the United States and the Soviet Union have conducted simultaneous hydrogen bomb tests.¹ The weather begins to change ominously: sun spots, power outages, freak mists, electrical storms, tropical storms in London, and a dwindling water supply as the River Thames dries up.²^•⁶

Stenning, aided by his new lover Jeannie Craig, who works at the Meteorological Centre, works out what has happened while the temperature continues to rise: the tests have dislocated the Earth and it is drifting closer to the sun.¹ In the script the concurrent tests each register 50 megatons and knock the world off its axis, in one account by 11 degrees, sending it spinning toward the sun.³^•⁷ The only hope is a series of properly timed corrective nuclear explosions in Siberia to realign the planet.¹ These take place, but the film ends with the reporters still not knowing which of two headlines, "World Saved" or "World Doomed", they will print; the final shots show both copies pinned up in the print room.¹^•⁸ On the last page of Barry Wells's 1961 novelization, the rains come and the Earth is saved.¹

Production and style

Val Guest, who had directed The Quatermass Xperiment (1956) and other science fiction and horror films for Hammer in the 1950s, made the film in a crisp, low-key, pseudo-documentary manner.¹ "I tried very hard to make it as 'documentary' as possible. I wanted it to be so authentic", he later said.⁶ The Daily Express offices were recreated at Shepperton Studios in precise detail, and much of the action is set in the newsroom with overlapping, naturalistic dialogue.⁶^•⁹

The film was shot in black and white in a widescreen 2.35:1 process by cinematographer Harry Waxman, with special effects by Les Bowie, including shots of the Thames completely evaporating in the heat.¹⁰^•¹ The scorching London of the later reels is realized largely with matte paintings and orange tinting, combined with documentary stock footage and authentic locations.¹¹ Former Daily Express editor Arthur Christiansen plays himself, thinly disguised as the hard-headed editor Jeff Jefferson.¹ A young, pre-stardom Michael Caine appears uncredited as a policeman at a roadblock.⁹

Filming in London

Shooting ran from mid-May to mid-July 1961, with extensive location work around the capital.⁶ Fleet Street scenes were staged outside the art deco Express building, but because the story required deserted streets, the police would close the road only two to three minutes at a time, so scenes had to be rehearsed and shot with military precision.⁶

Other locations included Battersea Park and its funfair, opened for the Festival of Britain in 1951 and closed in 1974, whose footage now serves as a visual record of the attraction; the Board of Trade building in Horse Guards Avenue standing in for the Meteorological Office; Chelsea Bridge; St Paul's Cathedral; and BBC Broadcasting House.⁶ Guest also requisitioned Trafalgar Square for an anti-bomb demonstration: actuality footage of a genuine Campaign for Nuclear Disarmament march was shot in April 1961, before principal photography began, and a smaller staged demonstration with Judd was filmed in June for intercutting.⁶ Some scenes mixing London settings were studio work: the Hyde Park water queues were shot against a photographic backdrop, and the Piccadilly Circus shots and the Fleet Street walking sequences that open and close the film were matte shots.⁶

Reception and legacy

The film received an "X" certificate from the British Board of Film Censors on release in 1961, barring anyone under sixteen from seeing it.⁸ Contemporary trade reviews praised its realism and its "question mark ending"; the Daily Cinema reviewer called the script "sharp as a tack" and predicted the film "can't fail to attract the queues".⁴ It subsequently won a British Academy Award for best screenplay.³

Scholarship on British Cold War science fiction treats the film as a work that combines apocalyptic spectacle, fog and tropical storms engulfing London, with social and political analysis, picturing CND protest marches and a beatnik riot alongside the disaster narrative.³ The BFI describes it as one of the earliest and still among the best examples of science fiction cinema tackling ecological concerns, and its depiction of a sweltering London as the planet heats now reads as prophetic.⁹ In the early 1990s Guest was attached to a mooted remake set in New York City, which fell through.⁸

Restoration

The British Film Institute restored the film in 4K, releasing a remastered high-definition edition from the original vault materials; the restoration is the source of Kino Lorber's Blu-ray special edition.¹⁰^•¹² The BFI lists the restored film in its collections of British cinema, science fiction, and "Nature Is the Enemy" titles.⁵
