Storyline

British Army radiation drills at a remote Scottish base attract a subterranean, radioactive entity of unknown nature that vanishes, leaving two severely radiation-burned soldiers... and a "bottomless" crack in the earth. Others who meet the thing in the night suffer likewise, and with increasing severity; it seems to be able to "absorb" radiation from any source, growing bigger and bigger. What is it?? How do you destroy a thing that "feeds" on energy? Written by Rod Crawford <puffinus@u.washington.edu>

Trivia

The movie began under the direction of Joseph Losey (working as Joseph Walton), exiled to England because of the Hollywood blacklist. However, when Dean Jagger arrived he refused to work with a director he thought of as a Communist sympathizer, and Losey was replaced by Leslie Norman before shooting began. Losey's departure was publicly attributed to "illness". It has also been reported that Losey simply didn't want to make the film and left the project, to be replaced by Norman, who also didn't want to make the film, but did anyway. See more »

Hard SF classic creepy from start to finish
24 December 2002 | by (Fountain Valley, CA) – See all my reviews

Back in the days when "Prince Valiant" still covered most of a page in the Sunday funnies, I first saw this wonderfully creepy SF sleeper. From the opening scenes of a stretch of the Scottish moors opening up under a British soldier's feet, I was hooked. I was very lucky that my parents didn't send me to bed then(although they did right in the middle of "From Hell It Came", but that's another story); I was resolved to catch it again just to get that creepy feeling! The ominous P.O.V. shots of the "X" monster shambling through the barren woods at night, the outrageous "melting" death by hard radiation of the medical tech in the X-ray room, Dean Jagger as Dr. Royston, describing his new invention that can (theoretically) speed up decay of radioactive materials without causing flare-ups(!) simply by leeching away its' energy, and the film's creepy, near-ambiguous ending ("We did destroy it...didn't we?") showed just what you could--and can!--still do with a small budget and respect for the material.
