Timothée Chalamet remembers the darkness. It was the summer of 2019, and the cast and crew of Dune had ventured deep into the sandstone and granite canyons of southern Jordan, leaving in the middle of the night so they could catch the dawn on camera. The light spilling over the chasms gave the landscape an otherworldly feel. It was what they had come for.

“It was really surreal,” says Chalamet. “There are these Goliath landscapes, which you may imagine existing on planets in our universe, but not on Earth.”

They weren’t on Earth anymore, anyway. They were on a deadly, dust-dry battleground planet called Arrakis. In Frank Herbert’s epic 1965 sci-fi novel, Arrakis is the only known location of the galaxy’s most vital resource, the mind-altering, time-and-space-warping “spice.” In the new film adaptation, directed by Arrival and Blade Runner 2049 filmmaker Denis Villeneuve, Chalamet stars as the young royal Paul Atreides, the proverbial stranger in a very strange land, who’s fighting to protect this hostile new home even as it threatens to destroy him. Humans are the aliens on Arrakis. The dominant species on that world are immense, voracious sandworms that burrow through the barren drifts like subterranean dragons.

For the infinite seas of sand that give the story its title, the production moved to remote regions outside Abu Dhabi in the United Arab Emirates, where the temperatures rivaled the fiction in Herbert’s story. “I remember going out of my room at 2 a.m., and it being probably 100 degrees,” says Chalamet. During the shoot, he and the other actors were costumed in what the world of Dune calls “stillsuits”—thick, rubbery armor that preserves the body’s moisture, even gathering tiny bits from the breath exhaled through the nose. In the story, the suits are life-giving. In real life, they were agony. “The shooting temperature was sometimes 120 degrees,” says Chalamet. “They put a cap on it out there, if it gets too hot. I forget what the exact number is, but you can’t keep working.” The circumstances fed the story they were there to tell: “In a really grounded way, it was helpful to be in the stillsuits and to be at that level of exhaustion.”
