Dunesday Is Here as Dune Smashes an IMAX Record

Hollywood's biggest same-day showdown in years has a nickname, a date, and now a first score on the board. Fans call it Dunesday: the December 18, 2026 collision of Dune: Part Three with Avengers: Doomsday, and the opening shot went to Arrakis. Dune Smashes an IMAX Record at the BFI IMAX in London, the largest screen in Britain, selling thirty-three thousand advance tickets in a single day for a first-day presale record at the venue, according to CBR.

The numbers behind the record are striking. The haul grossed eight hundred eighty thousand pounds in twenty-four hours, comfortably ahead of the previous mark of seven hundred fifty thousand pounds set earlier this year by the summer's Nolan epic. The venue's all-time first-day presale table now reads like a large-format hall of fame: the new leader, followed by that runner-up, then Dune: Part Two, Oppenheimer, and Avatar: Fire and Ash, each separated by a wide margin.

How the trilogy finale took the first round

The record landed days after general pre-sales began worldwide on October 20, 2026, opening every format and time slot for the first time after two earlier rounds that covered previews and select large-format screenings. The studio marked the moment with a brief "Now on Sale" teaser — more ticket announcement than trailer — plus a new poster placing Paul Atreides on the throne and a first single, "Desert Chant," from Timothée Chalamet and Hans Zimmer, according to Fiction Horizon.

The film itself is the closing chapter of Denis Villeneuve's trilogy, adapting Dune Messiah, Frank Herbert's sequel novel, and picking up seventeen years after the previous installment with Paul ruling as Emperor. Villeneuve has described the entry as more action-packed and thriller-driven than its predecessors, and said it will be his final Dune project. Warner Bros. is selling it as a big-screen event: the release carries a three-week global IMAX exclusivity window and seventy-one minutes of footage in IMAX's expanded aspect ratio, shot largely on large-format film cameras.

Marvel's answer arrives during tonight's World Series opener

Marvel is not standing still. The studio will air a new special look at its December team-up during the World Series opener on Friday night, putting the film in front of one of television's biggest live audiences, according to Men's Journal. MLB announced the crossover with a stormy short clip showing a packed stadium under churning skies as players watch the clouds gather — atmosphere that fits a story built around an enormous threat.

The campaign has been building all year: four teaser trailers, a full trailer, character reveals, and a countdown clock that fans now watch for glitches after an earlier stutter lined up with a trailer drop, according to Comic Basics. The latest rumor mill claims reshoots added a scene of Doctor Doom confronting Loki in the TVA that was originally planned to happen off-screen, though the studio has confirmed nothing and the claim comes from an online insider account.

Advance sales suggest the clash will be enormous on both sides. The superhero film pulled in sixteen and a half million dollars in its first day of advance sales and has passed fifty million dollars in presales, with seventy percent of those tickets for premium formats outside IMAX — a notable detail, since the rival's three-week IMAX lockout keeps Marvel off the format through the holidays. The film leads into Avengers: Secret Wars, dated for the following December.

For moviegoers, the takeaway is practical: the biggest screens will sell out first, and the calendar is already set. Preview screenings land in the UK on December 15, 2026, the international rollout begins the next day, and the Dune: The Experience attraction — giant sandworms, real props, a seat on Paul's throne — opens in downtown Los Angeles this November and runs through December 20, 2026. Industry coverage has already framed the night Dune Smashes an IMAX Record as the first official score of Dunesday: one side owns the IMAX screens, the other owns the biggest advance-sales machine in the business, and both arrive the same night.
