Speaking with IndieWire, Rebecca Ferguson, who was a standout as Lady Jessica in the first two Dune movies, confirmed she is returning for the third entry. “I donโt have a big part in this one, [sheโs] just barely in the book,” Ferguson said. “Iโm not sure I was supposed to be in it and Denis had a little idea. The script is phenomenal. Itโs really hard to create a film, itโs such a dense book. Thereโs so much to tell. [Denis] does dip in and out and he does try and he does want to have certain connections and tentacles to the book. Whatever Denis touches I think is phenomenal.”
Dune: Part Three Will Make Key Changes to Dune: Messiah

Ferguson’s return in Dune 3 is fascinating because Lady Jessica does not have a role in the Dune: Messiah novel. The book mentions that the character has traveled to the planet Caladan (home of the Atreides’ ancestors), which serves as the explanation for her absence from the story’s events. Lady Jessica doesn’t return to Arrakis until Children of Dune. Ferguson couldn’t share too many details about the size of her role, but her inclusion marks a notable deviation from the Dune 3 source material since Lady Jessica will physically be seen on screen. Whether she just appears in a vision or factors into the narrative in some way remains to be seen.
Children of Dune could provide some clues for how Lady Jessica fits into Dune 3. In that book, she comes back to Arrakis to examine Paul Atreides’ twin children, Leto II and Ghanima. Nakoa-Wolf Momoa and Ida Brooke have been cast to portray those two characters in Dune: Part Three, so perhaps the film will depict this plot beat from the novels. The casting of Momoa and Brooke as Paul’s children implies Dune 3 could skip over the extensive 12-year time jump between the events of Dune and Messiah and incorporate a few elements from Children of Dune. It will be interesting to see how Villeneuve crafts this story.
