Working for O.S.I., the Office of Scientific Investigation, A-Man agent Jeffrey Stewart and his partner Dan Forbes are sent to a local hardware store where they find a strong magnetic field has magnetized every metal item in the store. Investigating further, they eventually trace the source of the magnetism to an airborn flight carrying scientist Howard Denker, now dying of radiation poisoning, who has carted on board with him a new radioactive element which he has bombarded with alpha particles for 200 hours. The element, dubbed 'serranium' grows geometrically by creating matter out of energy which it absorbs from metallic objects surrounding it. Stewart calculates that if the substance is not destroyed soon that within 24 hours or so it will have grown large enough to throw Earth out of its orbit.

Did You Know?


Although credited to Curt Siodmak, most of the film was actually directed by Herbert L. Strock, who was hired by Ivan Tors for his skills as an editor, which were viewed as essential for a film that relied so much on stock footage. See more »


When loading the "serranium" on board a jet fighter, a T-33 is shown. However, when flying the "serranium" to Nova Scotia an F-86 is shown with its drop tanks attached. Yet the narration indicates that they were dropped. See more »


Howard Denker: It's hungry! It has to be fed constantly - or it will reach out its magnetic arm and grab at anything within its reach and kill it. It's monstrous, Stewart, monstrous. It grows bigger and bigger!

This is really good!
11 March 2001 | by See all my reviews

Forget the low budget and limited special effects. This is an exciting film. If you can transport yourself back to the time when science was young and naive, you can get caught up in this film. The "monster" is an isotope created by a mad scientist. It will, if not destroyed, eventually engulf the world. Earnest atomic scientists are in a race against time to transport it to Canada where the only instrument powerful enough to destroy it is located. Once there, they even run afoul of a jealous Canadian scientist who attempts to foil their last ditch efforts. The climax, with electricity surging and sparks flying is actually thrilling. This one has some of the laughs one expects from a low budget monster film, but it also achieves drama and excitement. The acting is even better than usual.

Now it wouldn't be a low budget film without at least one or two cheesy special effects. Don't miss the shot of some steel slugs tossed up and supposedly sticking to the magnetized ceiling; some of them actually roll off camera. However, this is just entertainment when combined with the taut, fast-paced story line, excellent performances and exciting climax. I recommend it.
