Timothee Chalamet believes that Dune: Part Three is a "different movie" from its predecessors.

The 30-year-old actor reprises his role as Paul Atreides in the concluding film in Denis Villeneuve's epic sci-fi trilogy and felt that it has a "new tone" when compared to the previous two pictures.

Chalamet said at an IMAX Q+A fan event in Los Angeles: "This is a different movie.

"I think the first two are sort of siblings, and then this one is really its own energy, and I love that approach.

"I was familiar with the crew and with this family, but there's a new tone to this."

Villeneuve expressed similar sentiments and claimed that the final project in his trilogy - which also features Zendaya, Jason Momoa and Florence Pugh - is a "very different beast".

The 58-year-old director said: "It will be the third and last Dune movie. It's a Dune movie but it is a very different rhythm and it's more intense."

Villenueve also revealed how he changed his approach to release Dune: Part Three just two years after the second movie, even though he had planned to do it "in a few years from now".

The Blade Runner 2049 helmer recalled: "We did both movies back to back and I was quite tired and said to everybody, 'Listen, I'm taking a break.'

"I went back home and two things happened. First of all I kept waking up in the night with images and these images started to get stronger and stronger.

"I felt an appetite and joy and a desire to finish that story and I felt a near responsibility.

"I was planning to do part three in a few years from now but I said, would it be a better idea instead of going back there on Arrakis by nostalgia, to go by necessity and honour these images that are coming to my mind right now?

"I wrote the movie right away and here we are. I'm really excited."

Meanwhile, Chalamet explained how he felt he was losing a part of himself in bidding farewell to the most "emotive" part of his acting career.

The Marty Supreme star said: "This is the most emotive on a personal level, not necessarily the character, but I've been living with this for so long.

"I'm so proud to live with it and so proud to work with Denis and his family.

"I felt there was a finality in the exercise that I was kind of nostalgic about, even the moment, even though I was 29 when we shot this, it still felt like, I was losing a part of me by getting through it."
