I haven't seen it either, but I just wanted to comment on how Disney seems to be trying to create stories for their attractions at their parks... Probably the best example is the Pirates of the Caribbean, which originally was just a pirate-themed ride but more recently has become a huge movie franchise for Disney. Similarly they made the Haunted Mansion into a movie with Eddie Murphey. I'm just thinking that Tomorrowland is just the latest version of making Epcot's Future World into a movie to further market the attraction.
