Timothée Chalamet rides a sandworm, Austin Butler a bald psycho in first 'Dune 2' trailer

LAS VEGAS – Timothée Chalamet pulled double duty last week at CinemaCon, but even he was upstaged by the sight of an orange-faced Hugh Grant as an Oompa Loompa.

At the convention for theater owners and studios, Chalamet introduced fresh footage for two of his upcoming high-profile star vehicles: the sci-fi sequel "Dune Part Two" (in theaters Nov. 3) – with a trailer that debuted Wednesday online – and the prequel origin story "Wonka" (out Dec. 15).

The "Wonka" sneak peek reveals the main narrative: how Willy Wonka became the greatest chocolatier in the world. Yet he's still an eccentric dude even as a youngster, as Chalamet's character concocts an assortment of sweets in his room (one of which makes people fly) and has big dreams of owning his own chocolate shop – although there's a candy cartel that stands in his way.

The wackiest moment involves Willy chatting with a small Oompa Loompa – played by Grant – who threatens him with a song he'll never get out of his mind. (In reality, his little flute tune just annoys Willy.)

"Wonka" felt like an opportunity to play a version of the character "that is full of joy and optimism and hope," Chalamet said.

Chalamet was joined on the CinemaCon stage by director Denis Villeneuve and co-star Zendaya to debut the first trailer of the "Dune" sequel. The second installment picks up where the 2021 film left off, with Paul Atreides (Chalamet) and his mother (Rebecca Ferguson) taking shelter with Chani (Zendaya) and the Fremen tribe.

"Paul will have to find the trust of Chani and she will become his moral compass," Villeneuve said. Highlights from the trailer included Paul riding a gigantic sandworm and a first glimpse Austin Butler's pasty, bald and extremely violent villain Feyd-Rautha Harkonnen.

"He played some kind of Olympic swordmaster cross-mixed with a psychotic serial killer. I’m very proud of what he brought to the movie," Villeneuve said.

The director also took a playful jab at Chalamet's other big movie: "Timothee came back with a real knowledge of chocolate, which was helpful for us."
