The prospect of a vast "underground city" linking the various parts of Disney World has tantalized fans for years, and a six-episode documentary coming to Disney Plus promises to explore them. A trailer for The Imagineering Story -- which will part of the streaming service's vast library at launch on Nov. 12 -- dropped Thursday, and it suggests that we'll learn a bunch of fun behind-the-scenes stuff about all the Disney parks.
"I don't know if you've ever walked through the hallways of a Star Destroyer before," says one of the Imagineers -- the engineers who design the parks -- in a comment that'll capture the imaginations of Star Wars fans.

The Imagineering Story promises an in-depth look at all the Disney Parks.

The documentary -- from Industrial Light & Magic: Creating the Impossible director Leslie Iwerks and narrated by Angela Bassett -- also promises to show us some of the "imperfections, the trial-and-error, and the experimentation" that went into the rides and attractions, including new Star Wars land Galaxy's Edge.
Disney Plus will cost $7 a month, and promises a healthy dose of nostalgia along with all of its new shows and movies.
