I promised to post some links to some Hayao Miyazaki movies, My Neighbor Totoro and Spirited Away. I would say that Totoro is great for preschoolers, and Spirited Away is better suited to school age kids.
The only one that I haven't let my 8 yo watch is Princess Mononoke. It's pretty violent and downright strange. I think I once heard a joke about needing to smoke a little something along with this movie, if you know what I mean. . . Just noticed on IMDB that Neil Gaiman wrote the English screenplay!
