Ray Harryhausen strikes again in It Came From Beneath the Sea. The 1950s nuclear bomb paranoia brings another irritated giant monster to attack mankind. The Wikipedia entry notes a humorous problem for Kenneth Tobey as he kept sinking in the sand next to Faith Domergue, and Harryhausen's budget only allowed for six of the octopus's eight tentacles to be animated. Thanks to ZC lurker Terry Michitsch for requesting this pressbook (and the one for First Men in the Moon, which I'll post as soon as I can find it. It's buried in the closet Terry, somewhere, I swear).
