"Dune: Part Three" is already starting production ahead of its current Dec. 18, 2026, release date, and one of its stars, Jason Momoa, just made a shocking transformation to get ready for filming.
Momoa was one of the biggest names in the first "Dune" movie (now titled "Dune: Part One"), but his character, sword-master Duncan Idaho, seemingly died off-screen, and he was therefore absent for the sequel, "Dune: Part Two."
