Charmingly silly and inconsequential monster movie has archaeologists in Asia discovering secluded mountain city run by snarling, villainous humans who have mole people as slaves. Fair B-movie production with good cinematography by Ellis Carter, but a sluggish direction from barely-imaginative Virgil Vogel. Screenplay by Laszlo Gorog may have been intended as an antidote for non-fans of "Lost Horizon": this city looks like the flip-side to Shangri-La! Not a classic by any means, with predictably wooden performances by John Agar and Hugh Beaumont, though not terrible.
