The film, based on Frank Herbert’s second novel in the Dune saga, is currently being shot in Hungary’s capital, Budapest.

Filming kicked off amid buzz about a major change in Timothée Chalamet’s appearance—fans noticed that the actor’s signature curly hair seems to be gone, sparking speculation that he shaved his head for the role.

Reports also say that Zendaya, who plays Chani in the series, has arrived in Budapest as filming is expected to take place at multiple locations and continue for several months. Meanwhile, fans spotted Chalamet vacationing in Saint-Tropez, France, with his partner Kylie Jenner. He was seen wearing a baseball cap with a green scarf wrapped around his head—possibly hiding his new hairstyle.

The previous film, Dune: Part Two, was a global hit, earning over $700 million worldwide and receiving five Oscar nominations.
