1000 Misspent Hours:
Go into Curt Siodmak’s The Magnetic Monster looking for a monster movie, and you’re going to leave sorely disappointed. What we have here instead is one of the most serious science fiction films of the 1950’s, and one of the very few that attempted to examine the newborn horrors of the nuclear age in a sober, non-sensational manner. The downside to that, as anyone familiar with 50’s B-movies has surely already guessed, is that The Magnetic Monster is also an extremely talky and laborious film, and considerable patience is required to get much enjoyment out of it.
TCM has an overview. The New York Times has a review.
I have a lot of trouble getting videos from veoh.com to work. It's so frustrating that I'm going to just ignore the films that are only available there. This is my last effort. This film is available there at this link if you want to make the effort.
