Dune spoilers follow.

Dune stars Jason Momoa and Rebecca Ferguson have spoken about their own personal favourite moments from the movie.

The pair take on the roles of Paul Atreides's (Timothée Chalamet) mentor Duncan Idaho and mother Lady Jessica, respectively, in the new sci-fi epic, which is based on Frank Herbert's classic 1965 novel.

Speaking to Digital Spy at the London premiere, Momoa explained which scene he wants fans to look out for with his character, admitting his final moment in the movie proved to be a particularly emotional one on a personal level.

"The last scene where I'm protecting my boy, Timmy [Chalamet] – Paul – it's pretty special to me because there's this moment where I do this to him [signals upwards from his chest with his hand]," he explained.

"It's kind of a moment to signal my own child at home," Momoa added. "It's a pretty heavy moment."

As for what Ferguson wants fans to keep an eye out for, the actress went for the much-anticipated worm.

"Oh the worm! I mean who wouldn't be?" she replied. "It's an exquisite worm! I'm in it, running away from it. It's exciting.

"There are emotional moments," the actress added. "There are so many layers of character, and there's so many choices of action that characters have to do and generating issues and chaos.

"It's a relationship drama set in space with enormous consequences."

Dune, which also stars Josh Brolin, Oscar Isaac, Stellan Skarsgård and Dave Bautista, first premiered last month, earning divisive reviews from critics.

In Digital Spy's three-star verdict, we wrote: "There's a lot to admire in Dune: Part One, especially in terms of the impressive world-building and the excellent cast.

"However, you're left thinking about how good the second part will be, rather than being totally fulfilled with this movie. Let's hope this isn't our only visit to Arrakis."

Dune is released in UK cinemas on October 21 and in US cinemas on October 22. It will also be available to watch on HBO Max in the US from the same day.
