Tierra desconocida

A military mapping operation goes awry and lands a helicopter in a hidden volcanic crater with live dinosaurs.

This movie oozes potential. A reasonable script, decent actors, good pacing, spectacular sets, and the grandeur of CinemaScope. Then you see the dinosaurs.... oh lord, do you ever. One can easily see where their budget ran dry. The movie employs the two worst methods of portraying dinosaurs, and doesn't even do it well. However, the compositing is nearly seamless, so if it were possible, one could become convinced that the producers managed to find a 20 foot tall man to wear a full size Tyrannosaurus costume.

Aside from the special effects, the movie is quite good, nearly rising above B-movie status. The actors all seem for the most part, naturalistic. They all seem to find the line between flat and hammy. The movie never wastes much time on non-essential plot elements, and the running time works out quite well.

Recommanded for those who love the genre type, be it dinosaurs or jungle movies.

Long before I ever knew about the existence of "The Land Unknown", I had already seen clips of its legendary T-Rex in various TV-shows spoofing bad movies and even wannabe funny commercials promoting the strength of cornflakes. It was like THE archetypal bad 'man-in-a-suit' monster that supposedly had to look ferocious but actually couldn't even fright the smallest child. Granted, the T-Rex looks ludicrous and pitiful, but bear in mind the movie remains a product of the 1950's and – in fact – the T-Rex is the only truly weak element in an overall decent and spirited little Sci-Fi effort. "The Land Unknown" also boosts an adequate screenplay, solid performances and direction and a couple of other and far more successful monster designs, including a Pterodactyl and some kind of Dino living underwater. Heck, the imaginative photography even manages to make smaller and "harmless" animals like iguanas and lizards look menacing. The story revolves on a scientific expedition heading for the continent of Antarctica to investigate why it could possibly have warm-watered seas and lakes amidst all the mountains of ice. A four-headed crew, one woman and three men, become trapped in a sudden storm and their helicopter lowers down a crater, far out of reach of all the headquarters' radars and search parties. For nearly 30 days, they are stuck in a subtropical landscape far below sea level and – even more astonishingly – where times didn't evolve and dinosaurs still prowl around. As paranoia amongst them rises and the hope for rescue lingers, the team faces the biggest ordeals in their lives. Okay, so "The Land Unknown" is rather tacky and often tedious, but it's undeniably charming and the opening quarter is even somewhat educational, with actual footage of the historically fundamental Admiral Byrd expeditions. The footage inside the crater and amongst the dinosaurs is obviously very grotesque and implausible, but hey, so was "Jurassic Park" and yet everybody loved that. Worth watching, but probably not for nowadays Sci-fi target audiences.

While in a military expedition to Antarctica by ship, helicopter pilot Lt. Jack Carmen (William Reynolds), mechanic Steve Miller (Phil Harvey) and civilian journalist Margaret "Maggie" Hathaway (Shawn Smith) travel to investigate a mysterious oasis with hot water under the command of Commander Harold Roberts (Jock Mahoney). However a pterodactyl hits the helicopter and they are forced to land below the sea level on a foggy land with dinosaurs and other pre-historical animals and plants. Soon they stumble upon the lonely Dr. Carl Hunter (Henry Brandon), lost in another expedition twelve years ago. He offers a way out to the three military provided they leave Maggie with him. What will they do?

"The Land Unknown" is a dated black-and-white adventure with a group stranded in a pre-historical land with carnivorous plants, dinosaurs and pterodactyls. The film is entertaining and it seems that in 1947 was discovered warm water in Antarctica. The good guys are military, still a reflex of the WWII, and the lead actress has the usual female attitudes of the 50´s, fainting and screaming when in danger. My vote is six.

Title (Brazil): "No Mundo dos Monstros Pré-Históricos" ("In the World of Pre-Historical Monsters")

A rip-roaring sci-fi adventure that has quite a lot going for it: a novel premise, a square-jawed hero, a lovely blond heroine, and several dinosaurs presented in a bizarre landscape.

Universal's ace effects artist Clifford Stine did a terrific job. The sets are also remarkable. The film's explanation for the presences of a tropical prehistoric world in the frozen Antarctic is intelligent and plausible. The character don't act like stereo-types, so the plot avoids being predictable. Be kind when you view the dinosaurs; they serve the story well, despite the fact that they're puppets, men in suits, and enlarged lizards.

If at all possible, see the wide-screen version. There's nothing worse than watching a dinosaur's mid-section attack somebody off-screen because the dino's head and tail have been cut

This rip-roaring sci-fi adventure scores high marks in several categories. The story concerns four people whose helicopter lands in an unknown prehistoric valley, a freak temperate zone located thousands of feet below sea level in the Antarctic, kept warm by volcanically-heated water and a permanent cloud layer that traps the warm air.

The special effects are by Universal's FX wizard Clifford Stine, and even though the dinosaurs are not animated, they aren't badly done. The Tyrannosaurus Rex is a man in a suit, the flippered dinosaur is fairly convincing puppet, and the rest are enlarged lizards. All the dinosaurs are skillfully integrated with live action shots.

Stine loaded the film with wonderful scenes of the fog-shrouded prehistoric landscape, using marvelous matt shots and impressive sets, creating a Skull Island atmosphere.

In some ways, this is the perfect 1950's sci-fi film, because it proudly presents a wealth of facts about the Antarctic before it begins its fanciful story.

The music by Joseph Gershenson is extremely effective. Director Virgil Vogel ("The Mole People") keeps the action moving right along. Hero Jock Mahoney (who later played Tarzan) is a stalwart hero, and Shawn Smith (the stern lady astronaut in "It! The Terror from Beyond Space" and the luscious babe in a mini-skirt in "World Without End") makes a gorgeous heroine. Henry Brandon does a commendable job as a half-crazed survivor from a previous expedition -- and I read somewhere that he was actually a member of the 1947 Bird Expedition to the North Pole. Don't remember where I read it, so I might be misinformed.
