Utterly ridiculous! The Mole People suffers from many things. First on the list is a preposterous screenplay that doesn’t have an ounce of believability in it! There is simply no way an ancient Sumerian civilization could survive underground for a week much less 5,000 years. To make matters worse their costumes look like something that was designed by either Ed Wood or a local High School drama department.
Then let’s talk about the Mole People who are the Sumerian’s slaves. Good God! They are not even so-bad-they’re-good. They are just plain bad. The only time they really look menacing is in the early scenes when we only see a brief glimpse of a hand or a set of eyes peering though a hole in the cavern. I do, however, like the effect of when the Mole People pull their victims through the earth. It’s the only thing that actually works in this film.
To be honest, I feel sorry for the actors, especially John Agar [Tarantula] and Alan Napier [Alfred form Batman] who are trapped in this film and are forced to utter inane dialogue form start to finish. The Mole People takes itself way too seriously and fails epically. You can skip this one altogether. While the cinematography and direction are good, filming crap is…filming crap!
