The Disney Studios have been having a hard time keeping activity going on in their soundstages. They'll pretty much let anyone film there because they don't want guests staring at empty soundstages on the tour. Currently Soundstage 3 is the Dooley and Pals show (not a Disney produced show), #2 has Donna's Day (Jim Henson Prod.) and Soundstage 3 has the leftover scenery from Mortal Combat (Disney bought the set so there would be something to look at).
Disney has decided to get out of the film production business at the Florida studios. The animation department will continue but the soundstages will be shutdown. They are going to install a replica of the "Who wants to be a Millionaire" set and guests will be able to come in and play the game (no real money involved).
