A potential trilogy based on the book series Dune is being discussed, with some outlets suggesting it could be comparable to the Lord of the Rings series. The main cast, including Timothée Chalamet and Zendaya, are reportedly enthusiastic about returning for a third film, and Denis Villeneuve is set to return for Dune 3, which is confirmed to be in development. However, it is unclear how this project relates to other reported developments, such as a potential season 2 update for Dune: Prophecy.
