Denis Villeneuve has confirmed that Dune 3, based on Frank Herbert's 'Dune: Messiah,' is underway, marking his final involvement in the franchise. Villeneuve emphasizes that the first two films were designed as a duology and not a trilogy, intending for the third film to have a distinct identity. While he is excited about Dune 3, he plans to move on afterward, leaving the door open for other filmmakers to continue the saga. The director acknowledges the complexity of adapting the later books in Herbert's series and describes them as increasingly esoteric. The third film will require aging up the characters, including those played by Timothée Chalamet and Zendaya.
