Dune Part Three Moves Up IMAX Previews, Skirts Clash

Dune's final act is arriving a few nights early. The third installment in Denis Villeneuve's sand-swept epic will kick off special IMAX screenings before its wide release, a strategic nudge that feels equal parts celebration and chess move.

Villeneuve closes out his trilogy with an adaptation of Frank Herbert's divisive Dune Messiah, following Paul Atreides — now played by Timothée Chalamet — as he navigates the throne he won at the end of Part Two and the galaxy-spanning holy war he set in motion. The film was set for a December 18 release, but IMAX theaters will start showing 70mm previews on December 14, with more venues and digital IMAX screenings added from December 15. Early ticketing is reported to begin in August.

Why the early run? On the surface it's a straightforward play: build momentum and reward hardcore fans with the biggest format possible. But there’s also a competitive angle. Marvel’s Avengers: Doomsday opens the same day as Dune’s full release, and studios don’t shy away from maneuvering when two tentpoles aim for the same weekend. Industry chatter has already dubbed the showdown “Dunesday.”

IMAX will have exclusive premium 70mm showings of Dune: Part Three for three weeks, blocking Marvel’s access to that particular premium window. That exclusivity could meaningfully shift early box office numbers, since audiences who want the most immersive presentation often prioritize those IMAX engagements.

Studios and theater chains rarely explain every scheduling choice. Warner Bros. and IMAX have given no detailed public rationale, which only fuels speculation. Is this about creating a word-of-mouth surge? About avoiding a head-to-head that could steal eyeballs? Likely both. Think of it as getting the best seats at the table before a crowd rushes in.

The timing also matters because premium formats have been red hot lately. Films like Sinners and The Odyssey pushed demand for IMAX-level screens, and that pressure has forced studios to find alternatives. In Dune’s case, Warner is doubling down on the IMAX experience; in another move, rival studios are pitching their own certified premium options. Disney and Marvel have started promoting Infinity Vision, a technical standard that certifies theaters as delivering a higher-end picture and sound experience — a way to offer a premium spectacle even when IMAX bays are occupied.

For viewers, the upside is obvious: more chances to see the film in the format that suits its scale. For studios, it’s a tactical bet. A few days of early IMAX play can generate headlines, social-media buzz, and advance revenue before the wider battle lines are drawn at the box office.

And for the rest of us? We get a few more nights of desert storms, standoff gazes, and Chalamet doing what he does best. Will Dune’s early IMAX push change the narrative of holiday box office dominance? Only time — and ticket sales — will tell.
