Pirates Of The Caribbean is one of Disneyland's most popular rides, and even though the story inside the ride has been whitewashed and given a Depp makeover in recent years it's still a fan favorite.
Walt Disney personally supervised the creation of the ride to ensure everything looked and felt right, but he originally intended for Pirates to be a wax museum type attraction.
The animatronics in It's A Small World and Great Moments With Mr. Lincoln were such a big hit at the 1964 World's Fair that Disney changed gears and made Pirates the animatronic heavy ride it is today.
Walt changed his mind about the Blue Bayou restaurant as well- it was originally going to include pirate themed dinner theater performances, which he cancelled after one dress rehearsal.
