Howls Moving Castle
yes
In the book "Howl's Moving Castle" by Diana Wynne Jones, Sophie doesn't destroy Howl's castle. Instead, she helps Howl regain control of his castle and break the curse that has been placed on him. Sophie's actions ultimately lead to the restoration of Howl's true form and the resolution of the conflicts within the story.
I don't think there is a release date yet for a US blu-ray. But if you are ok with subtitles there was a blu-ray released in Japan that you can currently buy on Amazon.
The climax of "Howl's Moving Castle" in the book is when Sophie confronts the Witch of the Waste in the final battle, breaking the curse on Howl and Calcifer and ultimately defeating the witch. This leads to a resolution where Sophie and Howl's love for each other is finally acknowledged and they are able to live happily ever after.
Well, probably not, because it was based on a book that is not a series. If you liked howl's moving castle, you could always read the book. Or if you don't feel like reading, you could watch the other movies by hayao miyazaki (if I spelled that right) like Spirited Away, Princess Mononoke, My Neighbor Totoro, ect.WHAT!? Howl's Moving Castle is a book in a series! The author of Howl's Moving Castle, Diana Wynne Jones, wrote two other books, 'Castle in the Air' and 'House of many Ways'.
