No doubt about it, Ray Harryhausen owned the 50s as far as Giant Creatures on the Loose Movies go. From THE BEAST FROM 20,000 FATHOMS (1953) on. But, that didn't stop other stop motion animators from practicing their craft. One of the lesser seen epics Is THE GIANT BEHEMOTH (1959). Like the film that was it's "Inspiration", Beast, Atomic Tests disturb a long dormant creature who rises from the Ocean Floor to cause havoc all over London. Makes a great poster. Even greater with artwork by Reynold Brown.
