OK.. I made a username just so I could respond to this thread.
My wife and I were at Disneyland Paris on Saturday, May 17th. We were in the 12:45 Animagique showing.
Approximately 6-7 minutes into the show (during the King Louie/Jungle Book scene), the scrim was brought down all the way and the house lights were brought up. My wife saw the black-lit monkey puppet completely dropped to the stage. Also just before the curtain was closed, I was able to see (what I thought looked like) two legs being dragged from behind the scrim and out of view.
After the show, I had asked one of the cast members at the front of the attraction what had happened. He responded that he was not sure. He was just told that they were having "technical difficulties".
If anyone could find out exactly what happened, I would greatly appreciate it.
