A volcanic eruption in the North Atlantic brings to the surface a 65-foot prehistoric monster. Two treasure divers capture the creature and take him to London where he is put on display in a circus. A scientist is thoughtful enough to point out that the sailors’ bonanza is only an infant, and that a full-grown specimen would be over 200 feet in height. Sure enough, Gorgo’s mama comes thundering ashore, reclaims her offspring and heads back to sea — but not before she trashes a generous portion of London. The special effects in GORGO, provided by Tom Howard — two-time Academy Award winner, are truly admirable. The monster is quite ferocious — except when he wiggles his ears. Released by MGM in 1961.
