Denis Villeneuve and Timothée Chalamet unveiled an action-packed new trailer for “Dune: Part Three,” marking the latest and most comprehensive look at the highly anticipated final chapter in his sci-fi trilogy.

The Oscar-nominated filmmaker and his star unveiled the new footage before an audience full of “Dune” devotees and press in Los Angeles, while the global Imax fan event was simulcast in Chicago, Dallas, Toronto, Montreal, London, Berlin, Mexico City and Abu Dhabi. The footage will be shown ahead of Imax 70mm screenings of “The Odyssey.”

The new film sees Chalamet return as Paul Atreides, continuing the story after his ascent to power at the end of “Dune: Part Two.” Inspired by Frank Herbert’s novel “Dune Messiah,” the third installment takes place 17 years after the events of the previous film and explores the consequences of Paul’s rule as Emperor. And things are getting…dark. Really, really dark. As lovers of the first film know, Paul is blessed with visions of the future, but his mind has grown clouded since assuming control of the galaxy.

“The future has a way of talking to me,” Paul intones. “I can’t see what’s ahead.”

And Paul has a new adversary in Robert Pattinson as Scytale, a shapeshifter who wants to dethrone the emperor. “We plan to strike the core of imperial power,” Scytale says. Making it clear that he wants nothing short of “regime change.”
