It does not cost $165m to write a book, or adapt a book into a script. Building a fictional world with art in such a way that it is believable is an epic endeavour, and the Art and Soul of Dune does a decent job casting a light on the intentionality behind designs that sometimes get only seconds of screen time.
Dune Pt I is a movie conveyed visually. Likewise, you won’t be reading this book for it’s prose, however the sketchbooks provide a feast for the eyes and an understanding behind the art of the universe that is just what I was hoping for and a great companion to watching the movie.
