There are only two worlds in the “Three worlds of Gulliver”.“The 3 worlds of Gulliver”, starring Kerwin Matthews (7th voyage of Sinbad), is based on the book “Gulliver’s Travels” by clergyman and author Jonathan Swift. (Reportedly a distant relative of mine.) Originally written as a political satire it has been adapted as more of a children’s story but usually with a moral. Published anonymously the original title of the book was “Travels into Several Remote Nations of the World, in Four Parts. by Lemuel Gulliver, First a Surgeon, and then a Captain of Several Ships.” In the book Gulliver made 4 voyages. Only two of the four voyages from the book are in the movie. And only two worlds of the three worlds promised in the title of the movie. Animation was done by Ray Harryhausen. Due to time constraints to get the film into theaters there were only two stop motion creatures created for the movie by Harryhausen, a squirrel and a crocodile. Both creatures were for the second world, Bobdingnag. So if you’re looking for monsters or lots of creatures you won’t find them here. They did use Harryhausen’s Dynamation process to incorporate the differences in perspective between the various actors. The first world is Lilliput where everyone except Gulliver is small and the second world is Bobdingnag where everyone is giant except Gulliver. Far from uncle Jonathan’s original intent “3 Worlds” is a movie for young children. Adults are invited to watch but children would most likely enjoy it more. Unless you saw it as a kid and need a little nostalgia.
