If you haven't been keeping up with the Disney theme parks, Disney–MGM Studios in Orlando is now Disney's Hollywood Studios. In 1994, they unveiled a terrifying roller-coaster with a drop shaft feature in a haunted house-type building called The Twilight Zone Tower of Terror. They now have the same ride at Disney parks in Tokyo and Paris. The thrill ride features Rod Serling as host, both in archival footage and an actor doing an impression. But it didn't start out that way.
When Disney first opened the movie-themed park in 1989, they were still brainstorming ideas for rides that connected to Hollywood movies. The Mel Brooks film Young Frankenstein was 15 years old, but was so memorable they were going to make a haunted house attraction based on it. The idea was presented as Mel Brooks’ Hollywood Horror Hotel, although staffers called it Hotel Mel. The premise was that Mel Brooks was in the process of directing a new movie there, and visitors would see classic monsters as animatronics in ridiculous scenes. What would that have been like, and why didn't it happen? Read the story of Mel Brooks' Disney attraction that never came to be at Cracked.
