Denis Villeneuve’s Dune: Part One brought a faithful adaptation of Frank Herbert’s novel to the big screen. The sci-fi film set up a universe in the distant future; one with noble houses, political maneuvering, and the spice melange. We learned the Padishah Emperor wanted to remove House Harkonnen from Arrakis, the planet where the precious and valuable spice comes from, and install House Atreides. Already divided by an ancient feud, the Harkonnens and Atreides further clashed over this change. The move to Arrakis spelled disaster for House Atreides, leaving quite a lot on the shoulders of the young Paul. And along the way, we learned about the spice, Fremen, the Bene Gesserit, and more. And that’s just Part One!

Dune: Part Two will soon arrive in theaters, bringing more intrigue, prophecy, and sandworms. If you’d like more information on the key topics in the Dune universe, we have plenty of Dune explainers to help you out.
