I don't really see how this will work. I hate the film so don't really like this idea. Also the fact that its only $500,000,000 is sad considering its Disney who are very bad when it comes to spending money on their attractions (Universal can do a better themed land for less money). Unless this goes over budget I can't see it being very good, considering the level of theming require for it based on the movie.
I can't understand why hating the film means you should hate the idea of the land. No one can argue the film is visually appealing and has potential for some fun rides. A lot of people weren't fond of the new Mummy movies, does that mean the ride isn't fun?
