Geek-culture expert Ryan Britt takes us behind the pages and scenes of the science-fiction phenomenon Dune, charting the series' life from cult sci-fi novels to some of the most visionary movies of all time.

Using original, deep-access reporting, extensive research, and insightful commentary, The Spice Must Flow brings the true popularity of Dune out into the light for the very first time. With original interviews with the beloved actors and directors behind the films—including Timothée Chalamet, Kyle Maclachlan, Denis Villeneuve, Patrick Stewart, Rebecca Ferguson, Alec Newman, and many more— The Spice Must Flow also examines the far-reaching influence of Dune on art, music, politics, and, most notably, its status as the first ecological science-fiction story specifically concerned with climate change.

Britt skillfully and entertainingly guides readers through the history of how the Dune universe has unfolded, including the novel’s unlikely evolution from a failed piece of journalism about Oregon sand dunes into an epic science-fiction story, the way Herbert’s work inspired George Lucas, untold stories from the 1984 David Lynch film, the knife-edge balance between blockbuster hit and indie film Timothée Chalamet brings to the 2021 movie, and the exciting future of the franchise. Through a blend of narrative, oral history elements, and fascinating trivia, The Spice Must Flow is the new essential guide to the behind-the-scenes story of Dune.

The fiction of Dune is deadly serious, but the real-life story of how it came into existence is full of wonder, surprises, and spice.
