Chalamet reveals which Dune 3 co-star scared him on set
Timothée Chalamet says Anya Taylor-Joy scared him on the Dune: Part Three set, calling her Alia Atreides performance "actually terrifying" and insisting the praise is not media hyperbole. The Oscar nominee made the remarks at a July 8 Global IMAX Fan Event in Burbank, the same day Warner Bros. unveiled a new trailer for Denis Villeneuve's trilogy finale. Fans now have a clearer picture of why Taylor-Joy's expanded role is shaping up as one of the film's biggest talking points.

Which Dune 3 co-star did Timothée Chalamet say scared him?
At the Global IMAX Fan Event on July 8, 2026, Timothée Chalamet did not hold back about Anya Taylor-Joy. Speaking about her expanded role as Alia Atreides, he said she is "unbelievable" and "actually terrifying," adding that the compliment was not promotional exaggeration.
Chalamet told the crowd he barely worked with Taylor-Joy during her surprise cameo in 2024's Dune: Part Two. That changed once she stepped onto the Part Three set. "The first day Anya stepped on set, just visually, it was breathtaking," he said, crediting director Denis Villeneuve and cinematographer Linus Sandgren for the impact.
Why does Anya Taylor-Joy's Alia Atreides role matter for Dune 3?
Taylor-Joy portrays Alia Atreides, Paul's younger sister and a pivotal figure drawn from Frank Herbert's 1969 novel Dune Messiah. The story picks up roughly 20 years after Dune: Part Two, with Paul having married Princess Irulan to secure peace across the Imperium—a peace that has not held.
That fractured political landscape pushes Paul into darker territory, and Alia's expanded presence signals a sharper turn for the saga's final chapter. For fans tracking celebrity breaking news, Chalamet's reaction suggests Taylor-Joy's scenes will be among the film's most unsettling.
What else did Chalamet reveal about Dune: Part Three?
Chalamet also highlighted Robert Pattinson, who joins the cast as Scytale. "I worked with Rob before. I knew how good he was," he said, calling both Taylor-Joy and Pattinson "something special" in the movie. The returning ensemble includes Zendaya, Florence Pugh, Javier Bardem, Josh Brolin, Rebecca Ferguson, and Jason Momoa, with Hans Zimmer again composing the score.
Separately, Chalamet framed the trilogy finale as a "warning tale" about following charismatic leaders, remarks he made at the same Global IMAX event, according to AOL. Principal photography ran from July through November 2025 in Budapest and Abu Dhabi, and Villeneuve is now deep in post-production ahead of the December 18, 2026 release.
