Three of my favorites that haven't been mentioned yet:
The Adventures of Baron Munchausen
In order to save the inhabitants of a walled town from a Turkish siege, the Baron embarks on a fantastical adventure to find his long-lost comrades-in-arms. Directed by Terry Gilliam.
Labyrinth
To rescue her baby brother from the Goblin King (a fashion-challenged David Bowie), Sarah (Jennifer Connelly) must navigate a labyrinth that leads to the Goblin Kings' castle. Lots of muppets in this one. Directed by Jim Henson. Produced by George Lucas.
The Wizard of Oz
Needs no introduction. I've always loved the Wicked Witch of the Wests' mountain castle.
