It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

There is, somehow, an interesting story here, as well as some good acting. There are also some good scenes

One of the most extraordinary films you will see this year. Take that as you want.

The acting in this movie is really good.

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.

A group of scientists who seemingly can't stand each other take a trip into the core of our world, determined to find safe shelter in the event of a nuclear disaster. Fighting amongst themselves for much of the journey, they come together in joy with the discovery of drinkable water in the earth's crust and in tragedy when disaster occurs. This isn't really a typical science fiction film, often staid yet occasionally filled with some vital points. The discovery of a possible utopia brings on more joy, some amazing (fictional) scientific finds, bringing more questions than answers. Told through the perspective of the one female scientist, it ends up being a statement against the advancement of nuclear power, insisting that humanity couldn't survive a really strong blast. Low budget yet sometimes imaginative, it still never fully comes to life.

I certainly must say that 1951's, Sci-Fi, Adventure tale, "Unknown World" sure turned out, for me, to be a humongous let-down on all counts.Had there been a really interesting rapport going on between the characters in the story, then, yes, I could've easily forgiven all of the shoddy special effects and the absolute sluggish pace of this "Journey-To-The-Centre-Of-The-Earth" yarn.But, alas, character interaction, like everything else in Unknown World, was unendurably lacklustre and painfully predictable.Yes. It was interesting to note that even back in the early 1950s there was considerable concern (amongst some citizens of the USA) regarding the dangerously fatal downside to the dawning of the Atomic Age for us humans.But, in the long run, this did nothing to alleviate the total humdrum that prevailed throughout Unknown World's story, from its somewhat promising opening to its downright cornball finish.Even from a purely nostalgic point of view, there was nothing about Unknown World that made it stand out in any way at all. It was just boring and forgettable. And that was, pretty much, it!

What should have been an interesting trip ends up as a rather dreary and none too exciting (despite filming in New Mexico's famed Carlsbad Caverns) slice of modest sci-fi. The main problem is not the cheap special effects (some are actually not too bad at all), but the characters. Without exception, they are a most unengaging lot. The heroine and Mr Kellogg are the only players that connect at all, though Miss Nash is often unflatteringly photographed and Mr Kellogg tends to out-stay his welcome. Otto Waldis, as usual, tries to hog the camera, managing to deduct at least two points from the film's appeal in the process. The other players just don't register at all. Blame Millard Kaufman's lackluster screenplay. This is certainly no Raintree County, let alone Bad Day at Black Rock.Despite his second-string cast, Terry Morse's direction manages two or three moments of real effectiveness, but in a 74-minute movie, that's far from an acceptable figure.
