Berkley Books publishes The Dune Encyclopedia, written and compiled by Dr. Willis E. McNelly and approved by Dune creator Frank Herbert (who would still contradict this book with some of his later Dune novels). The book, written from an academic point of view within the Dune universe, later goes out of print and is now considered a collectors’ item. 
The long-awaited, long-delayed feature film adaptation Dune premieres, based on the best-selling SF novel by Frank Herbert. Starring Kyle McLachlan (Twin Peaks), Sean Young (Blade Runner), featuring Patrick Stewart (Star Trek: The Next Generation) and Sting (lead singer of The Police), and directed by David Lynch (The Elephant Man, Twin Peaks), the movie meets with very mixed reviews, compressing many of the book’s events into a narrative that viewers not already familiar with the book find confusing.
PolyGram Records releases Toto’s soundtrack from the 1984 David Lynch film Dune, featuring additional music by Brian Eno. This release nearly doubles the numbers of tracks that featured on the original 1984 LP release.
Westwood Games and Electronic Arts release a soundtrack album from the PC strategy game Emperor: The Battle For Dune with pre-ordered copies of the game, featuring music by Frank Klepacki, David Arkenstone, and Jarrid Mendelson.
Cinewax Records releases, both digitally and on physical media, Kurt Stenzel’s score from the documentary film Jodorowsky’s Dune. Concerning an abortive 1970s attempt to commit Frank Herbert’s seminal SF novel to film, the music is done in an analog, 1970s style.
