Prigionieri dell'Antartide

This is a Universal low, low budget sci-fi movie modeled after "The Lost World".

Naval classes are being held before the next expedition to the South Pole. Harold Alan Roberts (Mahoney) will be in command, and reporter Margaret Hathaway (Smith) will be tagging along with two other crew members. They reach the South Pole, but then their helicopter crashes into a subterranean valley, still tropical in climate, with dinosaurs from the Mesozoic Era (according to the film). It follows a predictable path from here. The acting varies from boringly bad (Mahoney) to amusingly bad (Smith).

The movie is full of mistakes. Watch for:

The blown takes that made it into the finished film. Apparently the actors forgetting what mode of transportation they used wasn't deemed important enough to reshoot or the goofs weren't noticed.

There is also the giant iguana's costumes being ripped in their initial fight, the zipper running down the Tyrannosaurus Rex's costume, brooms disguised as oars, and the tiny set disguised as a forest, complete with lagoon. But without all of these mistakes this film would just be a bore.
