Dune(1984)

This one is definitely out there and really makes you think about cult classics as a whole and what that means. While slightly hard to explain this film it follows Paul, a prince, realizing his full potential and bringing peace to the galaxy by destroying the production of spice and the feud of 4 families. This film may have some of the worst CGI that we have ever seen but also has a few moments of action, suspense, and fantasy that is unmatched. If nothing else this film makes us want to know more of the lore from the books, but until then, we'll just keep waiting for the seeker to awaken.
