The whole park is a Studio- (In the magical way Epcot's a Community, and that there are Magic and Animal Kingdoms.)
The Studios is the theme that ties all of Entertainment together. In a Studio, that's where the entertainment is created. Hollywood Blvd. and Sunset are the Main Street of the park, to get you into the spirit of what the park is about. The director statue is even clearly placed looking over the entire "shot" of this fictional Hollywood that they've created: As if you're the actors in a film about a Golden Age that never actually existed.
There are even VERY EXTREMELY CLEAR TRANSITIONS INTO the "Working Backlot" portion of the Studio. The Studio Arch on the right side, and the security gates on the right side of the park. Beyond those you'll find working departments such as the Animation Courtyard, Pixar Place (The Pixar Department at the Studios), the backlot sets such as Epic, Star Tours, Streets of America, Catastrophe Canyon, as well as Boneyards, Soundstages, and the actual working wardrobe and prop department for all of Disney World. (Despite popular idiocy, Studios still does alot of real work on the Backlot)
Seriously, you people astound me that Epcot makes any sense to you, but Studios is this crazy upsidedown world you don't understand.
It makes my soul face palm.
So, did the film about the Golden Age never exist, or is it the Golden Age of Hollywood itself that never existed?
