I forgot about a current, little thing. I noticed throughout Magic Kingdom, there are a few cast members who make water paintings on the less populated walk ways, which is pretty cool (watched a couple of times).
Also, this past December, there were two things I never experienced. The first was in front of Pirates of the Caribbean, where they had a lot of pirates walking around, not for autographs, but as part of the scene. They would just sit in the bushes behind people and stuff like that. Some would be talking and then after a while, Captain Jack came out for a sword fight and some cool stuff.
Here's a picture from then, this is
after Captain Jack took care of some bad guys and he walked off the stage, past a bunch of people watching, and went through a door to back stage.
The second was the following day in front of Aladdin's ride. Aladdin and Jasmine were asking people what they wished for to try to get the Genie to come out. Eventually, the Genie appeared on top of one of the stores.
Both of these events were also being video recorded and I saw cast members taking notes, so this may have been a trial run for more interactive characters, but it was pretty cool.
