lewis-51 An interesting but rather odd and contrived story. Yes it's nice to see a serious attempt at authentic science. But it really fails rather badly at that -- even though it has the aura of authenticity.Why did the writers of the movie feel it was necessary to go to Canada? Did audiences of the time accept the oddly dressed workers as Canadians? They were, of course, Germans acting in a movie from 1934. As I write this in 2018, I wonder if other new viewers had the same thought as me -- they are going 1700 feet underground along the coast of Nova Scotia? My God -- it's Oak Island!!

Hitchcoc 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.

rick79robertson What a nice walk down memory lane! No saggy drawers or F bombs. If you like your sci-fi a little cheesy with some belly laughs, this film is perfect! The only thing that comes to mind that would have made this better would have been a cameo by Ed Wood and Bela Lugosi! This is NOT Oscar stuff here but it is enjoyable!!! There's lots of lightning and scientific jargon that makes you go Huh????? You also have the pretty young lady and all the crazy Doc Brown like scientists running around. This almost has a Frankenstein feeling to it. I watched this on TCM. It's nice there are still opportunities to see these movies made during the atomic/radiation scare days of the 50's. Pop the popcorn and sit back and relax and enjoy the corny special effects!

moonspinner55 Richard Carlson stars in this earnest, cautionary sci-fi as an agent from Boston's Office of Scientific Investigation discovering to his horror that a renown scientist has independently developed an artificial radioactive element which has taken on a life of its own. This isotope feeds on the energy around it, which doubles its size, and in time will harvest enough power to knock planet Earth right off its axis! Not-bad suspense thriller--with both textbook physics and non-textbook logic--smoothly incorporates footage from the 1934 German film "Gold" for its rousing conclusion. A low-budget entry in the man-made monster genre, but certainly an enjoyable one. ** from ****
