Howl's Moving Castle. I loved this movie the first time I saw it! Then I had a new found appreciation for it when I found out the all-star cast who did the voicing. Christian Bale as Howl, Jean Simmons as Grandma Sophie, Emily Mortimer as Young Sophie, Lauren Bacall as the Witch of the Waste, Josh Hutcherson as Markl, and Billy Crystal as Calcifer! WOAH!!! What a cast!!!
