As of right now, while Dune 2, i.e. the movie that will chronicle the second half of the original book, hasn’t officially been given the green light yet, Jon Spaihts, who co-wrote Dune with Villeneuve and Eric Roth, is penning the screenplay.
Brian Herbert recently described Villeneuve’s Dune as the “definitive” film adaptation of his father’s novel.
There’s also a prequel series in development for HBO Max called Dune: The Sisterhood.
Denis Villeneuve, whose credits include Prisoners, Arrival and Blade Runner 2049, had expressed interest for years in adapting Dune as a two-part film series, and in early 2017, it was confirmed he’d direct the project.
