Pretty feeble 50's sci-fi/horror takes that decades usual theme of atomic testing this time with it unleashing a snail/catepillar like monster that likes to suck on people's heads. It's up to the Navy, led by dashing commander Tim Holt, to try and stop it.

Below average stuff gets itself caught in the usual trappings of its decade with plenty of overdone dramatic moments, a slower pace and lots of stale sounding dialogue. Throw in the fact the monster looks like a rubbery hand puppet (which in one scene gives us a chuckle as it shakes about an obviously fake head in its mandibles) and a scientific description of radiation that nears mindboggling and you get this instantly forgettable, and passable, stuff.

It's definitely easy to get distracted when the small humour touches they attempted (like having one of the secretarys always on the phone to her mom) don't work and the creature looks so darn sloppy. And check it out in the finale where a woman and her little girl are trapped in a room with the monster busting its way in just to see the child actress standing there smiling(!).
