You see, when the ride was built in 1967, it cost $105 million -- a sum that went into making PotC the most in every way possible, from the animatronics to lighting to special effects to puffy shirts. According to a book by former Disney producer Jason Surrell, the only problem they had was finding decorative skeletons that didn't look like they'd spent the best part of the last century sitting in your grandma's attic. Utilizing the sort of ingenuity that lands you the job of designing theme park rides, the team hit up some friends at UCLA Medical Center and asked if they wouldn't mind handing out some medical specimens.
And it worked! The ride was a smash hit with park patrons, who probably weren't aware that they were now subject to the dumbest curse imaginable. Over time, the skeletons were replaced with better-looking replicas and given a proper burial. Or at least, most of them were. Maybe. Although it's hard to say for sure, there's reason to believe that there are still a few genuine body parts occupying the ride, identifiable thanks to the fact that they look a lot more ... discolored than the fakes, and also possess anatomical features that it's doubtful model makers would have bothered to include.
