As HBO Max’s Dune: The Sisterhood moves into production, Deadline reports that series creator and writer Diane Ademu-John is stepping down as co-showrunner. She will remain involved in the Dune prequel as executive producer. Writer-producer Alison Schapker, who was co-showrunner with Ademu-John, will now be the sole showrunner for the upcoming sci-fi series.

Schapker counts Westworld, Altered Carbon, Fringe, Lost, and Almost Human among her lengthy resume, so there’s no doubt that the series is in capable hands.

Starring Emily Watson, Shirley Henderson and Travis Fimmel, Dune: The Sisterhood – the series’ working title – is set 10,000 years before the ascension of Paul Atreides. It follows the Harkonnen Sisters (Watson and Henderson) as they fight dangerous forces that threaten the future of humankind, and establish the renowned and powerful sect of the Bene Gesserit.

The cast also includes Indira Varma, Sarah-Sofie Boussnina, Shalom Brune-Franklin, Faoileann Cunningham, Aoife Hinds and Chloe Lea. Denis Villeneuve, who directed, co-wrote and produced last year’s Dune, is executive producing the HBO series.

We’re likely to see Dune: Part II before we see The Sisterhood, as the former is set for a cinema on November 17th, 2023. No date has yet been set for the HBO Max prequel.
