What I like about this column is it generally tends to focus on the small details of the park that can be overlooked, but today, we're going big picture. As in, it doesn't get much bigger than this. We're going to answer the question why is the (then) Disney-MGM Studios brought forth? The origins of the Studios go back to actually Epcot and a project that Imagineers were working on that ballooned into something completely new.
Back in the early 1980's, Imagineers were busy working on ideas for some new pavilions at Epcot. They came up with a couple of ideas, one of which was a pavilion similar in nature to the Great Movie Ride we have today. It was to be placed between the Imagination and Land pavilions and feature a soundstage backdrop with a grand movie theater entrance and seemed like a great idea. Disney CEO Michael Eisner heard about the idea and liked it so much that he wanted an entirely new theme park built around the idea of Hollywood and show business.
With approval from the head of the company, Imagineers took the initial idea of the Great Movie Ride and built a park around it. Remarkably, the Great Movie Ride, which was the original idea for the Epcot pavilion, ended up being very similar in nature to the original idea for the Epcot pavilion.
