    • 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

      Andy Ostergaard: [Reflecting on the expedition's status deep beneath the Earth] You know once when I was working on the Holland Tunnel, I got cut off from my crew for ten hours. I felt this way then.

    Not as bad as I would have liked
    I thought that this would be a typical "lost world" type movie. A bunch of people set out on an adventure to find a hide away from the threat of nuclear war by drilling deep into the earth...sounds similar to a lot of other story lines. Problem is that with effects of this style (not too bad for the time), and acting this bad, I thought at least we would get a cave man or a cheap dinosaur. No, they just keep going deeper and deeper, losing members of the team as they go. It also ends so abruptly that you think the writer just gave up.
