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>

And I love it because...
26 May 2002 | by LarrySealsSee all my reviews

I love it due to the mercifully unmusical appearance of Anthony Newley - yes, *that* Anthony Newley. Appearing as L. Cpl. 'Spider' Webb, he disappears midway through the film without singing a note.

I too saw this as a youngster and had the crap scared out of me by the blob monster and the radiation induced deaths. As a former technician who used to work with isotopes and x-ray machines (non-destructive testing), it took a few years to get over my fear of working with radioactive substances.

One of the best of the early sci-fi pics - right up there with the Quartermass trilogy. Definitely worth the time and a bowl of popcorn!
