It's not impossible - Disney did 'Hunchback of Notre Dame', after all, and that turned out pretty well. (Of course, one of the reasons I say that is that the original book is one of THE most depressing and pointless novels ever written, in my opinion, unless you're a REALLY big fan of Parisian architecture - so just about anything would have turned out better.) I could see a Disney Phantom being done well, with a bit of creativity - if nothing else, Christine and Raoul would have to be fleshed out a bit, since the Phantom would inevitably be made more of a bad guy, which would make them the hero and heroine, and they're WAY too cardboard-cutout for those roles at the moment. They'd probably wind up using the Lon Chaney version for reference, and I have NO PROBLEM with that.
