There are more films that deserve attractions than room enough to build them, so I'll try to come up with a short list...
1. Nightmare before Christmas dark ride
2. Mary Poppins
3. Sleeping Beauty (all I want is a dragon AA, sort of like the yeti...is that too much to ask?
)
4. The Black Cauldron: I saw it for the first time a couple of weeks ago and was impressed with everything except the obvious film edits. No wonder the film was popular in countries that take animation seriously! TDL already has a walk-through based on it.
5. Monsters, Inc. door vault hanging roller coaster. No Pixar fan will ever be satisfied until one of these exists, most likely at the Studios.
6. Pinocchio
7. Fantasia boat ride: make it similar to the Jungle Cruise, but at AK.
8. James Bond at the Studios.
9. Either a better Narnia attraction, or none at all. The current show is little more than an extended trailer.
EDIT: Yes, I know that Bond isn't Disney.
