I bought this book on the recommendation of a friend whose taste in books and film is actually really good. So I bought this book from Amazon UK knowing I could trust in the opinion I was given, and as it turned out it really is a good book.
Being a fan of anime and in particular Studio Ghibli films coupled with me already owning a number of art books it was unfortunate I never knew about this book previously. From cover to cover it is filled with scenes from the creative process of producing "Howl's Moving Castle" and also includes a complete script.
It doesn't just show the creative process, it tells the story of how they went about developing this animated movie starting with them going on location to Alsace in France, moving on to drawing rough concept artwork and then moving on to design particular set pieces and characters and some of the final pieces.
It really is amazing to see how they produced this fun film and to see what they come up with along the way.Howl's Moving Castle [DVD] [2005
