I called Roy Disney's OLD number, from before he was out of Disney .... I got an answering machine, which is a good sign. I'll call back tomorrow and see who's at that number now, and if they know where Roy is.
I called Howard Green, a Disney publicist who worked on trying to get a proper DVD release of The Thief back in the late 90s. I was shocked to hear an answering machine message starring Roger Rabbit - Charles Fleischer! I left a message and will try again.
