EDITOR’S NOTE: Cosmic Monsters was on Chiller Theater on Sunday, October 5, 1963 at 11:10 p.m. It also was on the show on December 26, 1964.

Also known as The Strange World of Planet X, this film has scientists Dr. Laird (Alec Mango) and Gilbert Graham (Forrest Tucker) goofing around with magnetic fields and working with Brigadier Cartwright (Wyndham Goldie) and Michele Dupont (Gaby Andre) to solve their issues of needing massive amounts of energy to do their work.

While the military is interested in how they can use this research, the magnetic field gets so messed up that it causes brain wave disruptions and makes men into killers and bugs into giant monsters. Humanity must be saved by Mr. Smith (Martin Benson), an alien being with his own flying saucer, as Dr. Laird has lost it, sending giant spiders after Dupont and endlessly making magnetic mayhem.

At least it has a good tagline: “Shock by incredible shock this ravaging death overruns the earth…menacing mankind with overwhelming chaos!” The poster is pretty fun with the giant spider being the main thing and who doesn’t enjoy monstrous bugs? I once dated a scientist who would do experiments like seeing how long bugs could live without their heads and I referred to movies of this genre to warn her of the dangers. She refused to hear me.
