This movie is another example of the genius of Poverty Row studios, like Monogram, Republic, Mascot, etc. Who can argue with the kind of comedic mystery represented by Charlie Chan, The Purple Monster, The Tiger Woman, Radio Ranch, Rocket Man, and zombie movies like this.
The plot has to do with a mad scientist who wants to create an army of zombie Storm Troopers to help the Nazi's conquer America. (Be sure to look for an early scene where the zombies are assembled and goose step in formation). I don't think we need to go any farther into the story. It is only important to realize that this is Saturday Matinee entertainment in it's purest form.
It is one of the only forums where one can see the sinister elegance of a John Carradine, as well as the comic genius of a Mantan Moreland, all the while enjoying a virtual parade of second string pre-prime, and post-prime players. In this case we find Gale Storm (pre My Little Margie), and Bob Steele (post cowboy). A mute Veda Ann Borg, as the zombie wife, reminds us that her voice was as important as her acting. Speaking of Mantan Moreland; it is really too bad that PC guilt won't allow for the recognition he deserves.
I urge anyone who is interested in a little Saturday entertainment to catch this little gem if you can. You won't be disappointed. If you like it, and I know you will, you might want to check out another called "The Whip Hand".
