Timothée Chalamet said "competitive" is too strong of a word to describe the relationship that he and his co-star Austin Butler had while filming “Dune: Part Two."

Chalamet reprises in the new film his role as hero Paul Atreides, who now faces Butler’s maniacal character Feyd Rautha.

But he admitted that acting opposite Butler did inspire the already hardworking Chalamet in him to operate at an even higher level.

“I feel genuinely inspired by Austin,” he said. “I feel genuinely challenged by him in a great way where when you see people, your peers demand the most of themselves, it makes you demand the most of yourself.”

Chalamet added that while their fight scene was choreographed, the similar way they challenged and demanded the best from their own selves informed their work.

Meanwhile, after mastering Elvis Presley’s voice for his Oscar-nominated performance in “Elvis,” Butler learned to do his “Dune” character’s voice by mimicking the way Stellan Skarsgård’s character Baron speaks.

“With this one, I had approached it for a while just thinking I would use my own voice,” Butler recalled. “Every time I would play through scenes, it just didn't feel right for whatever reason. Then I said to (director) Denis (Villeneuve), ‘What if Fayd grew up with the Baron as his uncle, what if that's the voice that he emulates?’”

He added: “Once you start figuring out a voice, that in a way it's kind of the fingerprint of the soul, it changes the way you breathe and it changes the way you feel and your body. You never know what kind of link it’s going to be.”

Chalamet shot to fame through the 2017 film “Call Me by Your Name” and he followed it with solid performances in films like “Beautiful Boy” and “Little Women.”

It’s been about five years since he was cast in the first “Dune.” Now, coming off of the 2023 blockbuster hit “Wonka” and his critically acclaimed performance in “Bones and All,’ he’s a full-fledged Hollywood superstar and a critics favorite.

In “Dune One,” viewers got to see his character grow as he searched for his identity and place in the world.

Asked if this mirrored his own growth, Chalamet said: “It definitely did. I very much felt like in the years between where we shot these two films, I had time to grow in my own life."

Chalamet added that he finished the first film with the hope of completing the arc of a character.

"As an actor, you go through your script and you can kind of see the arc naturally of where you go and maybe the ups of the character," he said. "But I felt like at the end of the first movie, Paul has not ascended yet, which is the nature of the story.”

“Dune: Part Two” is now out in theaters.
