Dune 3: Jason Momoa Confirms Duncan Idaho’s Return for Denis Villeneuve Movie

Jason Momoa has confirmed that he’ll return as Duncan Idaho in Dune 3.

Momoa played Duncan Idaho, a swordmaster of House Atreides, in Denis Villeneuve’s Dune, which was released in 2021. Momoa did not return for the sequel, Dune: Part Two, as his character seemingly dies at the end of the first movie.

What did Jason Momoa say about Dune 3?

Speaking with TODAY’s Craig Melvin on Monday, March 31, 2025, Momoa confirmed that he’ll be returning to Arrakis for Dune 3.

“I’m making a comeback,” Momoa said. “You heard it first, right here with you, baby.”

Regarding how his character comes back, Momoa said, “Well, I’m not sure if I’m going to get in trouble or not, but it’s the same thing like Game of Thrones, you know what I mean? If you didn’t read the books, it’s not my fault, right? Yeah, there’s going to be … I’m going to be coming back.”

According to a February 2025 article published by Deadline, Dune 3 is looking to begin production sometime this summer, “providing key elements fall into place (talent avails, etc).” A release date for the film has not yet been set.

An official title for Dune 3 has also not yet been unveiled; however, the movie is expected to be an adaptation of Frank Herbert’s Dune Messiah, which is the second book (Villeneuve’s two movies have so far adapted the first novel) in his sci-fi series. Published in 1969, Dune Messiah picks up 12 years after Paul Atreides (Timothée Chalamet) has ruled as Emperor for 12 years.

Momoa, meanwhile, will soon be seen in A Minecraft Movie, which opens in United States theaters on April 4, 2025. The Aquaman star is also currently filming scenes for 2026’s Supergirl: Woman of Tomorrow, as he has been cast as Lobo in James Gunn and Peter Safran’s DCU.
