Mickey and Minnie's Runaway Railway is an upcoming dark ride, slated to replace The Great Movie Ride at Disney's Hollywood Studios in Walt Disney World. The ride features an original story, themed after the animated series Mickey Mouse, making it the first Mickey Mouse-themed ride-through attraction to open in the Disney parks' history. 
Prior to this attraction, there had been several proposals for a ride based around Mickey Mouse. In 1976, as part of the proposed Dumbo's Circusland expansion of Disneyland's Fantasyland, an attraction called Mickey's Madhouse was developed by Ward Kimball. This would be a wild mouse style rollercoaster dark ride through the world of early black and white Mickey shorts. Later versions of this concept would be called Mickey's Movieland and Mickey's Studio Tour and would feature a madcap Disney studio tour featuring numerous characters and setpieces.
The ride was announced at the 2017 D23 Expo in Anaheim, California, and will feature "2 1/2 D" technology (no glasses required). Disney Imagineer Kevin Rafferty stated: "This is one of the boldest…most impossible things I’ve ever worked on in almost 40 years of being an Imagineer. And you know what? That’s what I love about it. Well, that, and Mickey," [...] “This is not going to be a small attraction, it’s going to be game-changing.”
Furthermore, the Disney Television Animation team responsible for the recent, Paul Rudish helmed Mickey Mouse shorts are collaborating with the Disney theme park division and its Imagineers to bring the attraction to life.
Guest will step through the movie screen and join Mickey and his friends like never before. The attraction will put you inside the wacky and unpredictable world of a Mickey Mouse Cartoon Short where you’re the star and anything can happen. This zany out-of-control adventure features surprising twists and turns, dazzling visual effects and mind-boggling transformations that happen before your very eyes.
