This a really nice video i found on youtube, so enjoy:D
The book and the movie are so different:(
I like the video a little bit better because it's easier to understand and because i saw it first. I like moving castle and find the door pretty amazing. It can open on four different locations. The locations are determined by which color is turned facing down when opening the door. For the first half of the book; which is before howl moved and changed the castle the doors opens on the following location:
Blue: Porthaven A seaside town where the real castle is situated. Blue for the sea!
Red: Kingsbury The capital and the home of the King. Red for royalty.
Green: The moving castle!!! Always moving on the hill above Market Chipping. Green for grass!!!
Black: Wales Howl's sister Megan's front drive. A weird mysterious place... Black for darkness...
