"There are some characters that are less developed that I'm keeping for the second film — that's the way I found the equilibrium. We tried in this movie to stay as close as possible to Paul's experience," the director said. "Then, in the second one, I will have time to develop some characters that were left aside a little bit. That's the theory. I hope it will work." Production on the film, Deadline reported, is expected to start in the fall. The film will then premiere next October. Villeneuve will also return as a screenwriter for the sequel, as well as a producer. Dune: Part Two is set to premiere in theaters on Oct. 20, 2023.
