The Show

Unknown World

In “Unknown World” (1951), a team of scientists, backed by a thrill-seeking rich guy, hop aboard The Cyclotram, an earth-burrowing machine that takes them thousands of miles toward the planet’s core. Their goal? To find a geological haven should atomic war destroy Earth’s surface. They discover an underworld paradise that has all humanity needs to survive—all but one key thing, that is.

If you’ve ever been to Carlsbad Caverns, you may recognize some of the footage in the film. Located in a national park in New Mexico, the caverns were once the location of an inland seashore. They include numerous limestone chambers of remarkable size and features.
