This is very good 1950’s science fiction. At the center is Curt Siodmak, a pretty good writer who involves us in a tale where the use of a particle accelerator causes magnetism to go crazy. It results in implosions that could eventually end all life on earth. It’s up to Richard Carlson and King Donovan, staples in the movie genre of the time, to come up with a solution. This is post atom bomb time and we are treated to a lot of moralizing about life and its preciousness. This could have gotten out of hand but is reined in pretty well. I thought the science was reasonable and the acting quite good. Stereotyping was kept to a minimum and allowed the principles to do their thing. Very good scene in an appliance store at the beginning.
