Forrest Tucker stars as a scientist who is helping another scientist with tests involving magnetic fields. These tests get more and more intense until a mysterious planet sends an emissary to earth.
The alien, played by Martin Benson warns Tucker and his assistant, Gaby Andre that their experiments are changing life on this planet. It is creating monstrous insects and causing people to go insane.
This is one of three films Tucker made in England that are sci-fi. the others being "Crawling Eye" and "Abominable Snowman" which also starred Peter Cushing.
I have always liked this film an it was interesting to note that the title Cosmic Monsters appeared on this print instead of "Strange World Of Planet X". TCM has run this a few times, and it is always a joy to watch. I do with this would come out on DVD and Blu-ray.
This make for a fun 75 minutes monster romp as the Army is called in to fight the insects, an one scene in particular is shocking for it's time. Check it out if you haven't already.
