Messrs. Harryhausen and Bradbury serve up a thoroughly enjoyable dinosaur epic with a reasonable amount of thrills and typically excellent effects work by Harryhausen. It's rather heavy on plot and dialogue for a while, so the less patient of viewers may get a little restless waiting for the next good bit of dinosaur action. However, whatever pacing issues there may be are compensated for with some wonderfully iconic shots & scenes. The lighthouse sequence in particular is a gem.
Based on the Saturday Evening Post short story "The Fog Horn" by Bradbury, this tells of an atomic test in the Arctic that unleashes a ferocious rhedosaurus from its icy tomb. It goes about doing just what you'd expect any monster to do in this type of tale, making its way to NYC for the grand finale. Nuclear physicist Tom Nesbitt (Paul Hubschmid), one of the first to glimpse the monster, must convince paleontologist Thurgood Elson (Cecil Kellaway) that he wasn't hallucinating, and also enlists the services of Jack Evans (Kenneth Tobey) in hunting down and destroying this beast.
The acting is engaging across the board, with Hubschmid very likable in the lead; Paula Raymond plays his leading lady (fortunately, hints of romance that might slow down the action further are kept to a bare minimum). Intrepid Tobey is once again terrific as the kind of hero you need in such a story, and Kellaway is delightful as the old pro who is willing to put vacation plans on hold in order to participate in a historic expedition. Donald Woods, Lee Van Cleef, Jack Pennick, Frank Ferguson, King Donovan, and an uncredited James Best can be seen among the top notch supporting cast.
The exciting amusement park finale is of course the best part, with expert marksman Van Cleef and Hubschmid taking on the beast from atop a roller coaster.
Good fun overall.
Seven out of 10.
