Disney, constantly overtaken by reality?

[acroyear]

There have actually been a number of times where a really good idea suddenly becomes a really bad one, only because reality stepped in and turned comic fiction into tragedy.  Of course, this certainly proves the artistic perspective that comedy and tragedy are divided by an incredibly thin line.  Here's a few just in the last 10 years:

• In DCA's Superstar Limo ride, it was originally supposed to be a high speed ride (well, high speed is relative in a dark ride - think Mr. Toad) dodging paparazzi as you head through Hollywood highlights...only Diana, Princess of Wales was killed in a car accident doing pretty much exactly that in Paris.  (The ride got slowed down, they didn't have enough jokes to fill the time, and they didn't think the Muppets were hip enough to replace the original content (stupid choice), so they closed it down and turned it into a Monsters Inc darkride instead).
• Expedition Everest was originally going to go backwards because something would "go wrong" and the engine at the front of the train would break loose (based on an idea that Marc Davis had for the Florida Project over 40 years ago)...only that's exactly what happened by accident in Disneyland's Big Thunder Mountain in 2005.  Thus the change to "Yeti ripped up the track", which still works, I think.
• Lilo & Stictch's big finale was supposed to be Stitch hijacking a jumbo jet and flying it across the country, including past NYC's Twin Towers.  Well, 2 strikes against that idea happened during L&S's production.

Just a few, and there's probably more.
