This is one of the zeniths of bad films. We often hear about movies that are so bad they will make you laugh. This film is just one of those films. It's awful! A doctor has hidden himself away in the interior of Mexico on some huge mesa...way up in the sky that can only be reached by plane. His name is Dr. Aranya(that's spider in Spanish). Jackie Coogan, later to be rolly poly Uncle Fester, plays Dr. Aranya. Coogan looks and acts like a madman with his huge black mole and his incessant barking of orders. His performance is achingly bad. But soon he is supported by a horde of very bad performers. It seems that Dr. Aranya makes spiders into humans. The serum he uses only works well on girls and many of his female tarantulas turn into scantily clad females with big bosoms while the male spiders turn into hunchbacked, ugly midgets. Hmmm. Anyway, Aranya has a quarrel with a fellow doctor who has been hypnotized somehow, placed in a mental institution, and later found in a bar where he takes a group of five people with him in a plane that suspiciously lands on the mesa of the lost women. The actors start to die and we see midgets(one of which is famed Angelo Rossitto!) and more scantily clad women(one of which is Delores Fuller no less!) jump in and out of the light of the fire or a flashlight. The acting is just sooo bad and will have you laughing in no time. Harmon Steven plays Dr. Masterson, the fella who is hypnotized. He has an expression on his face that looks so corny and his dialogue made me wince with glee. The film ends as it begins with the two survivors telling the tale of how they escaped. The plot is like a bad serial from the forties. Easily the most annoying aspect of the film is the musical score of a guitar that plays almost throughout the whole film. It is repetitive and loud. I actually had trouble hearing what the characters were saying because that music would not stop. It had my hairs(what few I have left)on edge! The film even has a narration by Lyle Talbot of Ed Wood fame in the beginning. This is one of the most fun bad films I have ever seen. The acting, the direction, the script had me rolling with laughter. I don't know if anyone else caught it, but the name of the mental hospital was Muerto Hospital...Death Hospital. One major plus performance-wise is the sight of Tandra Quinn. She is breathtaking as she does her spider dance and exudes sex appeal. If you want to watch a real, real bad movie that will make you laugh...watch Mesa of the Lost Women. For my money it tops even Plan Nine From Outer Space as a truly inept in every fiber of its being film.
