The Happiest Place in the World
It should come as no surprise that this acclaimed movie had a very different ending originally, given that the script had been edited so many times by the end. The original movie, which was titled 3000, had a lot of Cinderella references; and perhaps that was why the script took Vivian and her friend, Kit, to Disneyland in an ending scene.

This was before the movie was bought by Disney, and it was quite a coincidence that the last scene took the two to Disneyland. But hey, we’re not complaining. It was a nice touch to take the two friends to the Happiest Place in the World. Because after all, where could a happy ending be depicted more accurately?
