    Not Bad Despite the Cheese Factor

    Cheapjack Lippert Pictures had an unexpected success with Rocketship XM (1950). I expect this little slice of sci-fi was intended as a follow-up (check out the similar opening scenes). However, instead of burrowing into outer space in a rocketship, these adventurers burrow into inner earth in what looks like a fat submarine with a drill for a nose.

    They're playing mole because staying on top like everyone else looks like sure death thanks to nuclear weapons. So six hardy Adams and one Eve set out in their big drill to found a new world and refuge for humanity. Naturally, things don't go entirely as expected, otherwise there'd be no movie. And, of course, not all seven survive.

    Actually, the special effects aren't bad considering the challenges of a fantastic inner earth. Then too, I'm surprised Lippert popped for location shooting all the way to New Mexico's Carlsbad Caverns. However, it's also a no-name cast that unfortunately performs like one, except for Killian and Nash who manage a few sparks of life. All in all, it's an interestingly offbeat slice of 50's sci-fi despite the big cheese factor.

    (In passing—thanks IMDb for the info on Killian's billing or I should say lack of billing. Killian was one of those distinctive supporting players who could make any movie better.)

    Low-budget and dated but surprisingly good

    A group of scientists drive an enclosed vehicle into an extinct volcano and then bore more than a thousand miles into the earth. They're searching for underground sanctuaries in case the surface of the earth becomes uninhabitable due to nuclear warfare. This is one of those low-budget, black-and-white films from the 50's that you want to laugh at it, and while it does have its share of bad dialog and cheesy special effects, there's an earnest, committed quality here which eventually overcomes most of the obvious faults. Viewers looking for cheap thrills will be disappointed.

    "Journey to the Center of the Earth" meets "The Core"

    Well, to be fair, in 1951, there was still a great deal of conjecture about the Earth's inner structure; not only was the theory of "plate tectonics" completely unknown (it's no longer considered a theory), that the core was a viscous super-heated liquid with a solid center (outer core and inner core) was merely a conjecture (today it too is considered fact). This picture strikes me as a sort of "Journey to the Center of the Earth" (1959) meets "The Core" (2003), with perhaps a little more emphasis on the latter.

    What was surprising was to see that the credit for music went to Ernest Gold (who appears to have scored a number of forgettable pictures earlier in his career). Gold would go on to score "The Young Philadelphians " (1959), "On the Beach" (1959), "Inherit the Wind" (1960), "Exodus" (1960) and "It's a Mad, Mad, Mad, Mad World" (1963); he won an Oscar for the score to "Exodus." Words were added in 1961 by Pat Boone(!) as "This Land Is Mine." Various versions charted in 1961, including by the piano duo Ferrante & Teicher and Montavani. It still can be heard today on radio stations that program older popular music.

    Better than you'd think

    This is not as bad a picture as some of the other reviews suggest.

    I'm not saying it's a great movie, but it IS surprisingly well done for being made with no money.

    It's an odd movie in that it's not really the kind of sci fi you'd expect. There are no monsters or other creatures.

    It a straightforward story about finding a alternative place to live in case of nuclear war.

    It does drag a bit, but it's worth a watch.

    The plot.

    Dr. Jerimiah Morley becomes convinced that the world is headed to an inevitable worldwide nuclear war.

    He organizes an expedition made up of a team of expert scientists and an atomic-powered rock-boring vehicle called a "cyclotram" to find a subterranean environment where holocaust survivors could live indefinitely.

    When funding falls through, independently rich adventurer Wright Thompson underwrites the project under the condition that he be allowed to go.

    As the group goes deeper beneath the Earth's crust, personalities clash, tempers flare, and the dangerous journey claims the lives of several expedition members.

    When they come upon an enormous underground expanse with its own ocean and phosphorescent light, it appears that their goal has been achieved.

    Very surprising

    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.

    • 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.
