The hometown of Superman was supposed to get even bigger in the 1970s with the addition of a super-sized theme park, but it never came to fruition. According to Comicbookresources.com, the city of Metropolis, Illinois was primed and ready for the newest addition to their already growing popularity. The park was supposed to be called The Amazing World of Superman. The place was going to be gigantic with everything dedicated to the Man of Steel.
The proposed layout was made in the early 1970s. The economic times were tough in the area and the park was hopefully going to fix the issue. The little town of Metropolis had already added elements of the comic books like a newspaper called The Metropolis Planet and free kryptonite available in City Hall. According to the article, DC Comics endorsed the idea and even declared the city of Metropolis the “Hometown of Superman” in 1972.
The park layout included a Fortress of Solitude, Bizarro playground, hotels, and a humongous statue of Superman that would act like the Colossus of Rhodes. The price at the time for building the park would have been around $50 million. The park never got off the ground because of the great oil crisis in 1973 that affected the tourist industry everywhere. Metropolis never got the theme park and instead received a river boat casino, museum, and the title of "Hometown of Superman."
