With the release of Denis Villeneuve’s Dune just around the corner, Warner Bros has shared the film’s final trailer, expanding on the narrative and hinting at how it could potentially continue into a yet-to-be-announced sequel.

Like the previous trailers, the final Dune preview packs in plenty of action, including wide-scale battle scenes, spaceship sequences, and someone riding one of the sci fi epic’s legendary sandworms. It also delves deeper into the training of Paul Atreides, the young nobleman played by Timothée Chalamet.

However, it’s a line from Zendaya’s Chani — who occupies the desert planet Arrakis, as well as Paul’s dreams — that hints there’s more to the story than unfolds in Villeneuve’s first instalment. “This is only the beginning,” Chani reminds us as the trailer draws to a close.

Back in September, Villeneuve revealed that he initially wanted to shoot Dune: Part Two at the same time as the first film, having pitched a two-part adaptation of Frank Herbert’s 1965 sci-fi novel. Looking even further ahead, he’s suggested the possibility of a third Dune film based on Herbert’s Dune Messiah.

Chalamet also hinted at a second instalment in August, saying that Zendaya is likely to play a “huge role”. While a script is underway, however, Dune Part Two is yet to be officially confirmed, and the go-ahead is reportedly dependent on the first instalment’s box office performance.

Talking of box office success, Villeneuve has also recently made some controversial comments on the type of film that is currently dominating cinema screens, and its lack of originality. “Perhaps the problem is that we are in front of too many Marvel movies that are nothing more than a ‘cut and paste’ of others,” he says. “Perhaps these types of movies have turned us into zombies a bit.”

Dune is set to hit cinemas on October 22. Watch the new trailer below.
