To me, this movie is perfection.

Sorry, this movie sucks

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

This movie feels like it was made purely to piss off people who want good shows

No need to recap the oft-repeated plot. Unlike many cheap 50's sci-fi, this one has big-budget aims—Technicolor, elaborate costuming, futuristic interiors. Trouble is it's still pretty hokey. Getting Hugh Marlowe as lead is like throwing in the towel straightaway. He's so bland, I forget he's there. Good thing for Rod Taylor who provides much needed energy. Then there's headliner Nancy Gates who gets about three lines and looks bored if not embarrassed. Good thing for Lisa Montell who provides needed energy on the distaff side.I would have liked the results more had the exteriors gone somewhere besides Iverson Ranch. My gosh, I half-expected Gene Autry or Roy Rogers to come riding through the set any moment, so familiar are the rocks and scrubby plants from old cowboy movies. Clearly, the production scrimped on locations. Then there's the battle scenes with the mutants that are about as well staged and suspenseful as a Woody Woodpecker cartoon. It does take more than an ugly face to suggest a fearsome adversary. On the skimpy plus side are the vaulted narrow passageways of the other world. They're both well done and highly suggestive. And, of course, there're the skimpy-skirted girls, as the producers well knew. Sure, it's easy to mock a turgid misfire like this. But I think there's a point to be made. Many of the best 50's sci-fi's didn't try to create eye-catching alternate worlds, the kind that consumes a lot of budget that could otherwise go into good casts and story lines. Here I'm thinking The Day the Earth Stood Still (1951), Them (1954), Invasion of the Body Snatchers (1956), Incredible Shrinking Man (1957). These are among the decade's best. More importantly, all worked with fascinating permutations of our everyday world, instead of alternate worlds whose construction was expensive, confining, and difficult for 50's special effects. Now of course, alternate worlds can be created with the click of a mouse, but not then.Anyway, it looks like the producers had much bigger aspirations than their budget could accomplish. And thus we're left with a half-digested film more obscure than most and deservedly so.

Spoiler alert, there are plot revelations exposed here!! There is much about this movie that has been well described by other reviewers. I will just add my take on the script from an intentional & sociological viewpoint. Getting past the bad spider scenes (Eight-legged Freaks is truly years ahead of WWE's predators) & the interesting space ship, this movie is about mankind. I saw Earth vs the Flying Saucers when I was a kid & comprehended only mechanical ships, not the human logic & relationships also portrayed (though I did understand what I saw in what I value as the greatest of the older, as well as, some more modern Sci-Fi films, Forbidden Planet). As in F.P., World Without End looks at the ethical challenges that help mankind grow. Although there seems to be no religious inferences in this film, versus some of the other 50's & 60s sci-fi pieces, (Them or Day the World Ended, for example) the title has a Biblical ring which may resonant with some.The space team of Marlowe, Leigh, Dark & Taylor grasp the problem of the underground society rather quickly. Due to defensive isolation, humankind has wilted into a society of wimps. Humanity will end with a sniffle or sigh if the robust pioneering spirit & seeking of a better (not necessarily a more materialistic) life of humans is not rekindled. There is some balance between the space team & the futuristic earth group, led by Everett Glass as Timmek. Although the isolated lifestyle & concentrated interaction of the futuristic council leads to errors in judging their ancestors from the past, the 4 astronauts are patient & graceful toward the underground group, & lucky due to Deena's honest intervention, until they finally are given the opportunity to rebuild society. This film has more to offer in reviewing our own present situation of life. Our politically correct culture will be the death of us if we do not boldly pursue our own origins & purpose...until the end.

A returning spaceship crew of four astronauts(including Rod Taylor & Hugh Marlowe) find themselves sent through a time-warp into the 26th century, where an atomic war has taken place, resulting in a primitive tribe of men on the surface, and a society of intelligent(but tyrannical) people living below. The astronauts discover that they likely can't get home again, and so must sort out this world if they have any hope of surviving(and dodge the odd giant spider!). Good cast, but silly film with a pulp-minded story and clichés. Still, it is interesting to note how this may have influenced "The Time Machine", "Planet Of The Apes", and even "Star Trek"! (Though they greatly improved on these ideas, and made them more imaginative.)

This must be the dumbest 1950's sci-fi movie ever.It starts of fine, (like an early version of Planet of the Apes)only instead of apes we get a race of "mutates" on the surface of the earth and a small group of "regular humans" who have built a society underground(A lot of similarities with the Timemachine).Our 4 heroes end up in a cave and are taken in by the regular humans,finding out that after a big nuclear war the surface dwellers were mutated into hideous,violent,Cycloptic Neanderthal-like "mutates" due to radiation,and a group of humans went underground.These underground dwellers degenerated into spineless peace loving hippie treehuggers with no stomach for violence whatsoever (which seems logical considering the earth was decimated by nuclear war) Our 4 heroes however disagree with this peaceful society and take it upon themselves to lead the treehuggers back to the surface where humans belong,and propose to create weapons to take the surface back,because the underground society will go extinct due to the oh so obvious inbreeding.Now i am not sure about the morale of this tale but i'm sure American 2nd amendment lovers should adopt this movie.
