DHS modern identity should be a showcase of all the flagship franchises of all the studios under the company's umbrellas against the background of a romanticized old Hollywood (ex: Tower of Terror, Brown Derby, Crossroads, Hyperion).
This would explain why and how Mickey (WDAS), Toy Story (Pixar), Star Wars and Indy (Lucasfilms), and Muppets (Muppet Studio) all exist in the same park. All that was missing was Marvel Studios and 20th Century Fox.
Monsters Inc. sorta puts an end to this theme though since Pixar is already represented. At least it matches their equally odd placement in DCA.
