Alongside Labyrinth, this is my favourite film. I really like IMDB's description of it:
"A classic fairy tale, with swordplay, giants, an evil prince, a beautiful princess, and yes, some kissing (as read by a kindly grandfather)."
This is one of those perfect films that appeals to children but there is so much more for grown ups too. It's a very tongue in cheek fairy tale. The book is just as wonderful. Another cult classic.
In fact, I want to go and watch it again...
