Here's the thing about Great Movie Ride....it should NOT be centered on just ONE movie. Turning it into a Guardians of the Galaxy movie would be nonsense, as we don't know how long Guardians will keep full steam ahead....and there are many wonderful films that NEED to be represented in the park. (Chiefly Indiana Jones, since I'm almost certain that any construction on a future "Star Wars Land" will necessitate the bulldozing of the Epic Stunt Spectacular)
How about THIS....same idea, that you get sucked into the movies as a 4-D experience comparable to Spider-man and Transformers....But you get sucked into different movie scenes.
To borrow from Walt himself....It should begin with a Mouse. Make it so that the audience is going to a screening of Fantasia. The queue area inside the theater with trailers would actually have theater seating.
You're sitting there, and the Sorcerer's Apprentice music starts playing....Mickey starts doing his Sorcerer's Apprentice thing, and naturally it all gets out of hand....however instead of merely creating zombie-brooms and tidal waves, Mickey's magic gets into the projector room. Reel after reel of film comes alive...and so does the theater. See, the theater you thought you were sitting in is actually made up of blocks of vehicles. Similar to Universe of Energy, but much smaller, each vehicle has seating for 16.
And thus, the theater breaks apart, each ride vehicle being sucked into a movie scene using the same trackless technology that Ratatouille and Mystic Manor both use. You might be in a fast motion Guardians of the Galaxy at one point, you might be in a slow From Here to Eternity.
I do stipulate that the Alien franchise is maintained. However, instead of the pure horror of the original, make it the action war film. You turn a corner, and instantly you're aboard the Sulaco, and there's Ripley in the power loader. She does a double-take when she realizes you're in the room so she yells at you to get out, that you're not safe....and at that point the Queen alien pops up. Ripley then fights her off to protect the ride vehicle.
Anyway, the last room would feature Yen Sid, taking over and putting the films back in order. He saves the ride vehicles and gets the passengers safely to the unload area.
I like. Send this to TDO.
