Demand Overload: When the attraction opened at Universal Studios Japan, it was so popular that it caused the park attendance to shoot up by 1.1 million people in less than a year.
Distanced from Current Events: When the ride first opened, the queue line had several news broadcast videos showing the Sinister Syndicate attacking the city by burning down buildings, attacking news reporters, and even making an attempt on the mayor's life. After 9/11, these clips were removed, which unfortunately caused the ride to lose a lot of its story development. It wasn't until sometime around 2009 that these clips were finally restored.
Keep Circulating the Tapes: The tie-in comic book for the ride, Marvel Super Hero Island Adventures, was only sold at Universal Orlando, and has since gone out-of-print, meaning that online sellers are your best bet if you want to read it.
Talking to Himself: Peter Parker/Spider-Man to J. Jonah Jameson, both of whom are voiced by Chris Edgerly.
Troubled Production: Plans for the sheer scope of the ride repeatedly changed dramatically, and programming the technology of the ride proved to be more troubling than Universal Creative was expecting. This resulted in the ride going incredibly over-budget, clocking in at well-over $100 million. While it ended up paying off in the end, it unfortunately caused many of the park's planned attractions to be either cut down or scrapped entirely.
Unintentional Period Piece: The rides adherence to the design sensibilities of Spider-Man: The Animated Series has become this years after that show was canceled. Hell, even after the 2012 refurbishment it's feels like this after they decided to kept the TAS designs rather than redesign the ride to be closer to either the Sam Raimi or Marc Webb styles. In retrospect, however, this might have been the right call due to Amazing Spider-Man's (the current series when the ride was refurbished) short life.
Early designs for this ride showed it not even being a Spider-Man ride, but a Superman ride, with the queue line going through the Daily Planet instead of the Daily Bugle. This was because the initial plans for the park had it having DC heroes instead of Marvel heroes, but after negotiations between Universal and Warner Bros. fell through, Marvel was ultimately chosen instead and the planned 3D ride became focused on Spider-Man.
Concept art by Gary Goddard showed the ride being accompanied by several smaller attractions themed around Spider-Man's villains, such as a twirler ride themed around Doctor Octopus and a walk-through funhouse themed around the Green Goblin.
Earlier drafts of the ride showed different villains being used, such as Mysterio, The Lizard, Venom, and the Green Goblin, as well as the ride vehicles being themed as more generic-looking cars.
The ride was planned to be cloned to Universal Studios Hollywood as well as Universal Studios Singapore, but the plan fell through due to disagreements between Universal and Marvel. The failure to clone the ride resulted in Universal creating the similar Transformers: The Ride for the parks.
Steven Spielberg had actually helped out with the creation of the ride, as well as with Islands of Adventure as a whole.
The ride won Amusement Today's "Golden Ticket Award for Best Dark Ride" for twelve years straight from 1999 to 2010, eventually being ousted by Harry Potter and the Forbidden Journey the year after. It also won a Thea Award for "Best New Attraction" from the Themed Entertainment Association.
