Waterworld? Or a 007 stunt show that uses a rethemed Waterworld stage it could be set in Dr. No's Laboratory and all the bond villains reunite in an attempt to stop him one last time. There would be a fake missile launch with opening roof, animatronic sharks (nod to JAWS) and plenty of real explosionsIf they get rid of Feat Factor and don't build more Potter they should be sued for theme park malpractice. It's the only other Potter expansion plot they have. They'd be foolish to use it for anything else.
Disney is opening up a STAR WARS land. Uni should open 2 new Potter rides to combat it, no question
