"Dune" director Denis Villeneuve says the sequel to the sci-fi movie will explore space traveling.

The 54-year-old director told Empire magazine that throughout the first installment he "tried to keep all the space-traveling as mysterious as possible, like almost bringing some kind of mysticism or sacred relationship with that part of the movie."

"Everything involving space is just evocated and very mysterious," he told the outlet Tuesday. "The Heighliners that are used by the Spacing Guild are ships."

Villeneuve explained that the process of creating the ships was very long. However, they came up with a circle-shaped design.

"I knew we had the right one. It feels like an echo to the worm, and at the same time it feels like it could be seen as a stargate," he noted. "It's like the system that [the Imperium] are using to travel and to bridge space and time is."

The director noted that will not reveal too much regarding the sequel and wants things to remain "unknown" to the audience for now as it is an "absolutely beautiful" thing.

Villeneuve admitted that he took a little bit of "liberty from the book, where it has a feeling that it could be something that is folding space in a way, that you can see it as almost as a stargate."

"Dune" is an adaptation of Frank Herbert's 1965 novel of the same name.

The movie was released on Oct. 22 in theaters and on HBO Max. "Dune" includes Timothée Chalamet, Zendaya, Rebecca Ferguson, Oscar Isaac, Jason Momoa, Stellan, Javier Bardem, Skarsgård and Dave Bautista.

The book explored a lot about space travel but very little was shown in the movie. It seems fans will get to see more space traveling in its sequel. The second installment is slated to release on Oct. 20, 2023.
