Although critics and audiences disliked it for being too gross and childish, the scene in which Gulliver saves the King from the fire in the palace by putting it out with urine is actually taken directly from Jonathan Swift's book. However, in the original novel, the person rescued in this manner is the Queen. The only other adaptation to include this scene is As Viagens de Gulliver (1996).
In the harbor containing all of the pun-named boats, the one to the far right is called Swift Passage, an allusion to Jonathan Swift, the author of the book upon which this movie was loosely based.
The Lilliputian palace is, in reality, Blenheim Palace, which is where former U.K. Prime Minister Sir Winston Churchill was born.
The stone jail where Lemuel Gulliver is imprisoned was modeled after a natural formation of volcanic origin in the northeast coast of Northern Ireland, consisting of over forty thousand interlocking basalt columns of distinctive shape. Quite appropriately, its Irish name "Clochan an Aifir" means "the Giant's Causeway".
