Throughout the film, Buzz Lightyear makes use a launch platform inside of a large structure. As the movie progresses, the structure looks more and more familiar. By the end of the film, the structure has a shadowed silhouette that is unmistakably that of Space Mountain.
While we don’t have clear screenshots of this later form, the trailers that have been released to this point do show the Space Mountain structure on several occasions.
So, rumor has it that Space Mountain at Disneyland will be overhauled (not simply receiving an overlay like Hyperspace Mountain or Space Mountain Ghost Galaxy) to represent the “Lightyear” film as the centerpiece of the Tomorrowland overhaul that will be under construction for the next few years. This rumor seems somewhat confirmed by the clear presence of the structure in the film.
What would the re-themed attraction include or change from the classic Space Mountain? We simply still do not know at this point as the project isn’t public yet.
Of course, the last several years have seen Disney focus on removing or overlaying many attractions and such that are either free of the inclusion of current franchises or are themselves original Disney Parks ideas. The Great Movie Ride, the Universe of Energy, and California Screamin’ are great examples of this, as is the Red Rose Taverne overlay permanently replacing the Pinocchio restaurant in Fantasyland at Disneyland. Toy Story also took over Redd Rockett’s Pizza Port near Space Mountain just a few years ago, making the establishment Alien Pizza Planet.
Space Mountain at Disneyland wasn’t free of this movement either as it saw extended periods of operation as Hyperspace Mountain, a Star wars overlay. In fact, Space Mountain at Disneyland Paris has been the Star Wars version for years now and the resort has even stated there are no plans to go back to anything else. If you think a permanent IP overlay of Space Mountain seems “far out”, ask European Disney fans about it.
