We told you about this one a while ago, but it now sounds like it may be happening and announced at the 2017 D23 Expo on Saturday July 15th…

From our August 2016 story:

While details are scarce at this point, rumors indicate the ride would be trackless and is also being developed to go somewhere at the Disneyland Resort simultaneously.

The latest trend in the parks seems to be Disney removing any connections to franchises that Disney does not own (Twilight Zone for example), and the Great Movie Ride is packed with a lot of films that Disney has absolutely no ownership over. The line of thinking here would be to feature the first ride ever devoted to Mickey Mouse (clearly the property of the Walt Disney Company), something that has been attempted many times over the last 60 years but never built in any Disney theme park.
