"Dreams are messages from the deep" ("Dune)" and "Power over spice is power over all" ("Dune: Part Two") are credited to an anonymous Sardaukar, an elite soldier.
Villeneuve specifically chose the Sardaukar as they are a dark mirror of the Fremen. He told the New York Times, "Frank Herbert said beginnings are very delicate times.”
Villeneuve continued. "By starting with a Sardaukar priest, I was indicating to the fans that I was taking absolute freedom with this adaptation, that I was hijacking the book."
