bnwfilmbuff Dull outing about a group of scientists and a financier embarking on a journey to find a refuge to escape what they have determined to be near certain nuclear holocaust by drilling into the earth. Reminiscent of "At The Earth's Core", this has none of the charm of that movie. Instead it focuses on a lot of pseudo scientific mumbo jumbo. The group goes down in a special vehicle called a Cyclotram but it doesn't do much. Much of the movie appears to be shot in a cave. There is the requisite conflict between the financier and one of the scientist. Nothing happens in this. Bad waste of time.

Rainey Dawn I like a lot of the older, slower sci-fi films but this one is super boring. It's extremely drab, flat, one dimensional and nothing happens. It just them drilling and drilling for most of the film. The exciting thing that happens is when the finally pop out and see water. That's as exciting as it gets - they see water. OK there's a little bit more to the water stuff in the ending but by the time you get to that point your either asleep or just really don't care.If you are gonna watch the film, there is no need in watching it normally, just hit the fast-forward button and watch it that way because the dialogue is as interesting as the sock-lent between my toes.1/10

wes-connors "A scientist has a theory of saving mankind from a nuclear disaster by having people hide in the center of the Earth to avoid the contamination and devastation. With the financial backing of a multi-millionaire, the scientist develops a giant drilling rig and sets out to find the potential safe haven in the Earth's core. A harrowing trip through the Earth brings the explorers to a hidden cavern…" according to the DVD sleeve's synopsis. Blacklisted actor Victor Kilian (as Jeremiah Morley) leads the underground movement.The journey to the center of the Earth is made possible because our planet is mostly cool and hollow. After the six man/one woman crew finds an underground sea, you may agree they have found the "Promised Land" - but, wait until you see if reproduction can occur below sea level. In an unrelated subplot, arrogant Bruce Kellogg (as Wright Thompson) romances the world's weirdest "ardent feminist" doctor, Marilyn Nash (as Joan Lindsey). As you'll immediately discern, this pretty blonde never did get around to burning her bra.** Unknown World (10/26/51) Terry Morse ~ Victor Kilian, Bruce Kellogg, Marilyn Nash, Jim Bannon

MartinHafer The film begins with some stock footage about nuclear war and is part of a presentation scientists are making in order to drum up support for an ark, of sorts, to be sent deep within the planet. This way, in case we have a nuclear war, the species can survive deep inside mother Earth. The story, at times, is highly reminiscent of Jules Verne's JOURNEY TO THE CENTER OF THE EARTH.When I rented this film, I assumed based on the box cover that it was a typical low-budget 1950s sci-fi/horror film. However, to my surprise, there were no bug-eyed monsters, alligators or lizards with cheap fins pasted on or silly masked ghouls. While it certainly did not have a huge budget, the film made a genuine effort to entertain, have SOME basis in scientific facts of the day and say something about mankind. While some might find this all pretty dull, I actually enjoyed it more than I thought and in hindsight I am glad the usual silly and schlocky monsters and such were missing. Now this isn't to say this is a masterpiece. Occasionally, the characters behave a bit silly--such as their needlessly bickering (which makes no sense for such an expedition) and the science behind all this is suspect (such as the lack of differences in air pressure, the presence of drinkable water as well as breathable air over a thousand miles inside the Earth and their ability to ascend at an incredible rate without exploding!). Still, it is oddly compelling and the acting (while they weren't arguing) was pretty good. Plus, unlike JOURNEY TO THE CENTER OF THE EARTH, it's nice NOT to see dinosaurs and other creatures waiting to greet our heroes.Final verdict--well worth a look and a decent time-passer despite some limitations.PS--This film is from Alpha Video--one of the worst producers of DVDs out there. Fortunately, unlike many of their films which are scratchy public domain prints, this one is a very good copy and is very watchable.
