Quite possibly the most-desired unbuilt concept in the Disney portfolio is Tony Baxter & Harper Goff’s iconic Discovery Bay expansion planned for Disneyland. This steampunk-infused land, to be located just beyond Big Thunder Mountain, would celebrate “an age of discovery and expansion” and feature attractions based on the works of H.G. Wells, Jules Verne, as well as the 1977 film, The Island at the Top of the World. The project floundered when that film, seen as a jumping-off point, bombed at the box office. However, remnants of this one-of-a-kind land exist at other Disney Parks worldwide. Elements of can be found in the Verne-esque idealized future stylings of Disneyland Paris’ Discoveryland, while Tokyo DisneySea’s stunning Mysterious Island is a love letter to what Discovery Bay could have achieved. Figment, EPCOT’s signature purple dragon, and his cohort The Dreamfinder, also found their start as part of Discovery Bay.
