Ok here is my pitch for the park.
Universal Studios Metropoli Theme Park.
It is as if USF and Epic had a love child.
You enter the park straight on to the central Lagoon like Epic. No "Main Street". At the back is the grand hotel, like Epic. But surrounding the Lagoon are 4 Cityscapes. Hollywood, New York, London and Tokyo.
Each city will have a "Portal" themed to a theater in the back, and also a secondary attraction in the City area.
Hollywood: a typical Universal Hollywood area with the Chinese Theater in the back. The large marquee and giant posters say Jurassic World: Something Something. You enter the theater/portal and pop out in Isla Nublar. A full blown land similar to HTTYD in Epic but instead of the tall skinny mountain you have the Innovation Center with the JWA ride from Beijing inside. There is also a family launch coaster and a flat.
The secondary ride in the Hollywood section would be a Universal based GMR using classic Universal IP like JAWS, BTTF, Psycho, Monsters, etc. themed like the USH tram tour, utilizing the Kong/F&F ride system. Have the shark attack the "tram" like it attacks the tram in Hollywood. Use the 360 tunnel for BTTF.
London: I don't know what the most famous movie theater in London is but that facade/Portal and the marquee would be showing Lord Of The Rings: Something Something. Enter the theater, exit the portal into Middle Earth land. Universal Creative do your thing.
The secondary attraction in London would be a bookshop facade that houses a Paddington ride similar to, but more charming than SLOP Hollywood.
Tokyo: again movie theater/portal showing Mario's and Luigi's Excellent Adventure! (Full blown Nintendo Land)
Secondary attraction would be Fast and Furious: Tokyo Drift Coaster!
New York:
(OK here is where I go totally off the rails, but bare with me.)
New York:
Secondary attraction: KONG!
It also uses the Kong/F&F ride system, but uses a lot of the practical effects from Earthquake. You leave the bus stop and round the corner where a practical set shows crumbling buildings, sparking power lines, a broken fire hydrant geyser and just general destruction, as the bus crosses the Roosevelt Bridge you see Kong the first time destroying the city. Leave the bridge into the 360 tunnel where Kong chases you, catches you, looks into the bus for his love, puts you down and turns around and walks off, bus speeds off into the final scene with a screen showing Kong on top of the Empire State Building swatting at planes.
Theater/Portal: Gershwin Theater on Broadway where Wicked has played for 21 years. You enter the theater/portal. Boom, Oz!
Since Potter is off the table, Glinda and Elphaba interactive wands. This is where they would use the Forbidden Journey ride system for Glinda's Bubble E Ticket and a B&M Flyer Flying Monkey coaster would be.
Ok this is just a rough up. Let me know what you think. Would you pay money to go to this park?
