Featured review

Serious but indifferently acted and sluggish sci-fi.

As with ROCKETSHIP XM, Irving Block, Jack Rabin and the Lippert Company were trying to make a serious science fiction film with something to say. To the films credit, UNKNOWN WORLD is not exploitive or stupid as Rabins and Blocks next film ,CAT WOMEN OF THE MOON was. Years before I first saw this film, I owned a still of the drilling machine that takes the cast to center of the Earth and found it rather interesting looking. Its not bad looking in the film, and the scenes of it drilling into the Earth are of some visual interest. However, the film is just to lethargic and indifferently acted too be of interest to anyone other 1950's science fiction buffs. The trip to the center of the Earth is just to slow going.

Trivia
This project was actually put together by two special effects men, Jack Rabin and Irving Block, who are listed as producers.

Goofs
The "science" regarding the interior of the earth is wrong, and was known to be wrong at the time the movie was made. It does not get cooler the deeper one goes into the earth. A few feet below the surface the ground temperature is around 50 degrees Fahrenheit. Going deeper from that depth the temperature goes up at a rate of approximately 1 degree Fahrenheit per 70 feet.

Quotes
Dr. Jeremiah Morley: I believe that humanity can escape annihilation, can find a temporary haven, a promise of hope that, come what may, life can be sustained deep within the Earth itself. Far below the Earth we shall seek a natural, a geologic shelter. We have a team ready for the effort. All we lack are funds.
