The Last Unicorn, of course.
The Princess Bride, definitely.
The Sword in the Stone
The Little Shop of Horrors
Several of the Narnia stories have been filmed, successfully.
The Nightmare Before Christmas (1993)
The Butcher's Wife (1991)
Interview with the Vampire
James & the Giant Peach
Matilda (by Dahl)
The Fisher King
Groundhog Day (1993) (and check out GroundhogDay.com)
Dead Again (1991)
And the one, the original, the only Highlander. I make every effort
to ignore the existence of either of the creatures called sequels. I
enjoy the TV show, especially the naked sweaty male muscles, but I
dread the rumors of a new movie with the TV characters.
The Adventures of Baron Munchausen: both the one with Robin Williams and the older one.
The Neverending Story (a framed site)
Continue the Neverending Story(a framed site, but with a no-frames version)
Ferngully, the Last Rainforest
I'm reaching back a bit, but I have to include The Wizard of Oz; the Piglet Press website gives a great tour of the land and its inhabitants, as created by L. Frank Baum.
Who Framed Roger Rabbit?
Animation Art from Who Framed Roger Rabbit? This site also credits the book that most people forget, Who Censored Roger Rabbit? by Gary K. Wolf, which is a very good read if you can find it.
Army Of Darkness
Attack of the Killer Tomatoes
The Rocky Horror Picture Show
Flesh Gordon (not Flash Gordon, Flesh Gordon. Including my
favorite claymation monster, with a voice reminiscent of Vincent Price,
attempting to molest the heroine. Like everybody else was doing.)
Earth Girls Are Easy
(Off the subject: I also enjoyed Serial Mom and Lust in the Dust. Can you tell?)
I did not like
The Conan the Barbarian movies. Good fantasy movies are made by people who love the genre. The Conan movies were not made by someone who grew up on Barbarian
Fantasy and loved it. They weren't even made by someone like Terry
Pratchett who knows the literature of Sword & Sorcery enough to have
playful fun with it. They were made by someone who was saying, "Let's
see, the product they are buying is ... swords ... check ... naked
sweaty male muscles ... check ... barbarian swordwomen in
unrealistically skimpy outfits ... big monsters, snakes and stuff
... evil magicians ..."
