This "surefire box-office attraction" (L.A. Free Press) delivers a daring, diabolical, dinosaur-laden fantasy adventure that's packed with "hair-raising beasties and erupting fire" (Daily Variety) every second. When an expedition in search of a lost colleague traces his last steps in the frozen Arctic, the team discovers a hidden, tropical oasis in the middle of all the ice! As things quickly thaw out, clothes come off and long forgotten cavemen--and dinosaurs--come a-hunting for fresh meat. Soon, prehistoric hysteria sets in and it's every man--and scantily clad woman--for himself. Original Theatrical Trailer, NTSC.
