If you are interested in topic as psychology and science fiction, you should read Dune by Frank Herbert, if you haven't read it already :)
And if you haven't watched the move already, you shouldn't it doesn't convey important motifs from the book.

Dune is by far one of the best books, not only in genre but generally. Story follows young Paul Atriedes, a son of one of two most powerful noble families. His family moves to the planet Dune. Whole planet is a desert and is used for mining spice. The spice is psychedelic substance which gives insight into the future, and only with insight gained from the spice is the space travel possible.
The book is truly remarkable, I have never seen someone create a civilization and connected it with environment as good as Frank Herbert did with Fremen - the native people of planet Dune.
