It would be hard to overstate the influence of Dune in science fiction—and, by extension, our science-fictionalized pop culture in general—over the last half-century or so. Take the broadest outline of the plot: A chosen one, ordained by an inscrutable interstellar religion, uses deadly mind powers to rise up from a barren desert planet to battle the evil galactic emperor. If it sounds familiar, it’s because Star Wars imported all of that from Dune. 

At 20 million copies moved, the book is considered the best-selling science fiction work of all time, even today, over 50 years after its original publication. This is fairly insane, considering that it has never had a single hit cinematic adaptation or popular television tie-in, the fuels that juice our pools of permanently recirculating IP. Outside dedicated fandoms and science fiction reading circles, the Dune “brand” was famously nonexistent. Until now, maybe.
