Time to check in on 1968's Adventures of Gulliver, which, along with the Arabian Knights & Three Musketeers segments on Banana Splits, marked the end of Hanna-Barbera's first era of adventure.
In "The Dark Sleep", Captain Leach (John Stephenson) enlists the aid of an old witch, who creates a sleeping potion, intent on eliminating Gary Gulliver (Jerry Dexter) so Leech can steal the treasure map. However, the Lilliputian King (Stephenson again) ends up getting the potion instead, and so Gary and friends have to find the antidote.......
